What is the answer to -3+5+6g=11-3g

Find the number needs to be added to both sides of the equation in order to complete the square

x ^2+16x=18

In completing the square , we take the coefficient of x and divide it by 2

Then square it and add it on both sides.

The coefficient of x  is 16

Half of 16 is 8

Then we square it . [tex](8)^2 = 64[/tex]

Add 64 on both sides

[tex]x ^2+16x + 64=18+64[/tex]

Now we factor x^2 + 16x+64

[tex](x+8)(x+8)=18+64[/tex]

[tex](x+8)^2=82[/tex]

so 64 is added to both sides of the equation in order to complete the square.

Answer:

x=1

Step-by-step explanation:

When the argument of the absolute value is positive, the equation has no solutions. It is equivalent to -3 = -1.

So, the only solution is found where the argument of the absolute value is negative:

-(2x -3) = 2x -1

4 = 4x . . . . . . . . add 2x+1

1 = x . . . . . . . . . . divide by 4

Answer:

The first answer is that x = 3. The second is that x = 6.

Step-by-step explanation:

To find either of these, we need to follow the order of operations.

2 + x = 5 ----> Subtract 2 from both sides

x = 3

2(4x - 8) = 32 ----> Distribute

8x - 16 = 32 -----> Add 16 to both sides

8x = 48 -----> Divide both sides by 8

x = 6

slope = [tex]\frac{1}{4}[/tex]

to calculate the slope m use the gradient formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (8, 8 ) and (x₂, y₂ ) = (- 4, 5 ) ← 2 poinys on the line

m = [tex]\frac{5-8}{-4-8}[/tex] = [tex]\frac{-3}{-12}[/tex] = [tex]\frac{1}{4}[/tex]

In general, if you have a parent function, f(x), the graph of a daughter function f(x - h) + k is related with the graph of the parent function as per these rules:

Therefore, the graph of  f(x) = |x - h| + k is a translaion of h units to the right and k units upward fo the function f(x) = |x|.

Since, the graph of f(x) = |x| has vertex (0,0), the graph of f(x) =  |x - h| + k has vertex (h, k).

To visualize the images of the graph, assume some positive value for h and k. For instance, h = 3 and k = 5.

See the image attached showing the graphs for the functions f(x) = |x| (red line) and f(x - 3) + 5 = |x - 3| + 5 (blue line). As you can see, the blue line is the translation of the red line 3 units to the right and 5 units upward.

i know things...

[tex]210^{o} and 260^{o}[/tex] are not quadrantal angles.

A quadrantal angle is formed by two lines which lie on x-axis and y-axis.

For this reason, angles like;

[tex]0^{o},90^{o},180^{o},270^{o} and also -90^{o},-180^{o},-270^{o}[/tex] are quadrantal.

However, on the other hand,

[tex]210^{o} and 260^{o}[/tex] are not quadrantal because these angles are not formed by lines lying along x-axis and y-axis.

Answer:

210 and 260 degrees are not quadrantal angles

Step-by-step explanation:

quadrantal angles are angles that directly fall on the x or y axis. They're also multiples of 90 degrees. Quadrantal angles are 0, 90, 180, 270 degrees. hope this helps!

Answer:

19:00 or 7:00 PM

Step-by-step explanation:

Baby armadillos need to be fed every four hours.

Baby bats need to be fed every three hours.

So we need to figure out when will they be fed again at the same time:

Basically, we need to find the LCM of two numbers i.e. 4 and 3. And the reason why are we finding the LCM is because that time difference will is the least common multiple of both the time differences, it is the smallest non-zero number that is the multiple of both 4 and 3.

The LCM of 4 and 3 is 12. So the time when they will be fed again at the same time will be 12 hours after 7:00 AM that is 19:00 hours or 7:00 PM.

option E) 30 is the answer for the square root of 75 times the square root of 12

We start by using the property of square roots that states the product of two square roots is the square root of the product of the numbers. This gives us:

[tex]\sqrt{75} \times \sqrt{12} = \sqrt {75 \times 12}[/tex]

Now we can simplify the expression by finding the product of 75 and 12. This gives us:

[tex]\sqrt {75 \times 12} = \sqrt{900} = 30[/tex]

Thus, the square root of 75 times the square root of 12 gives 30 as the answer. So, option E) 30 is the correct answer.

Correct question:

The square root of 75 times the square root of 12.

A. the square root of 63

B. 3 times the square root of 7

C. 3 times the square root of 3

D. 8 times the square root of 3

If you look at the graph, the x axis the the number of hats and y axis is the cost.

So 8 hats will cost $60

Answer

D. The cost of 8 hats is $60

Answer: The cost of 8 hats = $60.

Step-by-step explanation:

In the given graph , the x-axis is representing the number of hats and y-axis is representing the cost of hats ( in dollars $).

To find the cost of 8 hats , just look at the x-axis and search for point x=8 on it .

Then , draw a straight line vertically passing through x=8 or just look at the dot marked above x=8 on the graph.

Then check the y-value associated with that dot or draw a horizontal line from that point , you will get y= 60

It means, the cost of 8 hats = $60.00.

Answer:

c. Definition of altitude.

Step-by-step explanation:

We are given that segment QS is an altitude in ΔPQR and we are asked to find a justification used while proving the similarity of triangles ΔPSQ and ΔQSR.

Since we know that altitude meets opposite side at right angles. When QS will intersect line PR we will get two right triangles QSR and QSP right angled at S.

ΔPQR is similar to ΔPSQ as they both share angle P and right triangle. So their third angle should also be similar.

ΔPQR is similar to ΔQSR as they both share angle R and both have a right triangle at Q and S respectively. So they will have their third angle equal.

ΔPQR is similar to triangles ΔQSR and ΔPSQ. Therefore, ΔQSR is similar to ΔPSQ.

Therefore, by definition of altitude triangles ΔPSQ and ΔQSR are similar as ΔPSQ and ΔQSR are created from ΔPQR by altitude QS.

Answer:

[12/(4c)] + [12/(6c)] = 2.5

Step-by-step explanation:

time = distance/speed

You know the speeds upstream (5-1)c and downstream (5+1)c, the distance, and the total time for both trips. This information can be combined to give the equation above.

_____

The first equation assumes the trips upstream and down took 2.5 hours each.

The second equation is an incorrect combination of the numbers, as the units on the left are miles²/hour and are equated to hours on the right.

The third equation makes appropriate use of the relation between speed, distance, and time.

Answer:

Last option as

[tex][12/(4c)] + [12/(6c)] = 2.5[/tex]

Step-by-step explanation:

Time = distance/speed

Speed of boat = 5c (given)

Hence upstream speed = 5c+c =6c and

downstream speed = 5c-c =4c

Distance remains the same 12 miles for up and down

Total time = 2.5 hours

The first equation assumes total time as 5 hours when it is actually 2.5 hours.

The second equation is an incorrect because time x distance will not yield any result instead distance /time should have been done.

The third equation calculates time taken for upstream and downstream and add to equate to 2.5 hours.

So this is correct.

Answer:

m = kg

Step-by-step explanation:

125 = 5k   , k = 25  where k is the constant of variation.

175 = 7k,  k = 25

Direct variation m = kg

Answer:

[tex]m=kg[/tex]  direct variation

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

In this problem

Let

m------> the number of miles traveled

g------> the number of gallons used

we have that

[tex]\frac{125}{5}\frac{miles}{gallons}=25\frac{miles}{gallons}[/tex]

[tex]\frac{175}{7}\frac{miles}{gallons}=25\frac{miles}{gallons}[/tex]

The linear direct variation that represent the situation is equal to the equation

[tex]\frac{m}{g}=k[/tex]  or [tex]m=kg[/tex]

where

k is the constant of proportionality

In a direct variation the constant k is equal to the slope m of the line, and the line passes through the origin

[tex]k=25\frac{miles}{gallons}[/tex]

substitute

[tex]m=kg[/tex] -------> [tex]m=25g[/tex]

Answer:

1. See below for the table

2a. Early Pay: y = 45

2b. Deposit Plus: y = 12 + 4x

2c. Daily Pay: y = 6x

3. See the second attachment for a graph.

Step-by-step explanation:

1. The deposit (Deposit Plus) and the flat rate (Early Pay) are paid whether or not any days are spent swimming. For Early Pay, there are no additional charges, so the total cost is the same regardless of the number of days spent swimming.

For Deposit Plus, the $4 per day cost will add $20 for each 5 swimming days.

For Daily Pay, the $6 per day cost will add $30 for each 5 swimming days.

2. As described above, the Early Pay and Deposit Plus have charges when the number of swimming days is zero. The Daily Pay does not. The Deposit is only paid once, not each day.

a. Early Pay: y = 45

b. Deposit Plus: y = 12 + 4x

c. Daily Pay: y = 6x

3. The above equations are graphed in the second attachment. You will note that the plan that results in a minimum charge depends on the number of swimming days.

Answer:

2a. Early Pay: y = 45

2b. Deposit Plus: y = 12 + 4x

Paula's dog : Carolos' dog = 3 : 1

The total number of ratio units is 3+1 = 4, so each one stands for (48 lb)/4 = 12 lb.

Paula's dog weighs 3·12 lb = 36 lb.

Carlos' dog weighs 1·12 lb = 12 lb.

Answer:

A) -9/4

Step-by-step explanation:

The answer ends up becoming -2.25.

So if you do the math, that's -9/4. or add up 4 until you're at 9.

4, 8. Now we know we have 2 whole. What's left? 1/4.

So now we have, -2 1/4. or "-9/4".

The only equation that has 3 as the coefficient of x (a slope of 3) is ...

... d.) y = 3x+4

_____

Happily, it also goes through the given point.

... 5/2 = 3(-1/2) +4

... 5/2 = -3/2 + 8/2 . . . . true

The equation of the line with a slope of 3 that passes through the point (-1/2, 5/2) is y = 3x + 4, which corresponds to answer option (d.) y = 3x + 4.

To find the equation of a line with a given slope and that passes through a specific point, we can use the point-slope form of a line, which is y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the given point. So, for a line with a slope of 3 that goes through the point (-1/2, 5/2), we can plug in the values to get the equation.

Substituting into the point-slope form, we get y - 5/2 = 3(x + 1/2). Simplifying and solving for y will give us the equation of the line in the form of y = mx + b. After distributing and rearranging, the equation will be y = 3x + 4.

Therefore, the correct answer is (d.) y = 3x + 4.

there is enough acres to support 3 cattle on their farmland .

Michael's family's 210-acre farmland can support 630 cattle, with each cow needing 1/3 acre for grazing.

To find out how many cattle Michael's family's farmland can support, you would divide the total acreage by the amount of land each cow needs for grazing.

Given:

- Michael's family has 210 acres.

- Each cow requires 1/3 acre for grazing.

You can calculate it like this:

[tex]\[ \text{Number of cattle} = \frac{\text{Total acreage}}{\text{Acreage per cow}} \][/tex]

[tex]\[ \text{Number of cattle} = \frac{210 \, \text{acres}}{\frac{1}{3} \, \text{acre/cow}} \][/tex]

To divide by a fraction, you multiply by its reciprocal:

[tex]\[ \text{Number of cattle} = 210 \, \text{acres} \times \frac{3}{1} \, \text{cow/acre} \][/tex]

[tex]\[ \text{Number of cattle} = 630 \, \text{cows} \][/tex]

So, Michael's family's farmland can support 630 cattle.

356 + 365 + x = 977   where x is the number of students in the third grade.

to find x  subtract 356 and 365 from 977

x = 977-356-365 = 256

The equation of the given problem will be as; 356 + 365 + x = 977 . Therefore, there are 256 kids in the 9th grade.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

It is given that the combined enrollment in the three grades at Jefferson Middle School is 977. there are 356 students in the 7th grade 365 in the 8th grade.

Equation:

356 + 365 + x = 977  

where x is the number of students in the third grade.

Since there are 977 kids in total, we have to add 356 and 365 to get 721.

356 + 365 + x = 977  

721 + x = 977  

Then subtract 721 from 977 to get how many kids are in 9th grade.

x = 977 - 721

x = 256

Therefore, there are 256 kids in the 9th grade.

The variation statement tells you that when the radius is multiplied by 5, the volume is multiplied by 5² = 25. When the height is multiplied by 1/2, the volume is multiplied by 1/2.

Both of these variations together will multiply the volume by 25·(1/2) = 25/2.

So, the revised volume is (2π in³)·25/2 = 25π in³.

A. The loan balance decreases $500 per month.

We can see from slope of our given line that loan balance is decreasing $250 per month, therefore, option A is incorrect.

B. Harrison makes a monthly payment of $250.

We have seen that our slope is negative 250 this means that loan balance is decreasing $250 per month. This implies that Harrison makes a monthly payment of $250, therefore, option B is the correct choice.      

C. The loan balance increases $250 per month.

We can see from our graph that our slope is negative, which means that loan amount is decreasing, therefore, option C is incorrect.

D. Harrison increases his monthly payment by $500 each month.

Since we know that linear functions have a constant rate of change, therefore, option D is not true regarding slope of the line.

To work this problem, you must assume that Juan's pedaling speed adds to the wind speed when going downwind, and that the wind speed subtracts from Juan's pedaling speed going upwind. (In other words, Juan's pedaling speed is relative to the air, not the ground.)

Let w represent the wind speed in miles per hour.

... distance = speed × time

Juan's total distance is 40 miles, so we have ...

... 40 = (11.5 +w)×1.75 + (11.5 -w)×2.50

... 40 = 48.875 - 0.75w . . . . . simplify

... -8.875/-0.75 = w . . . . . . . . subtract 48.875, divide by -0.75

... w = 11.833... = 11 5/6

The wind was blowing 11 5/6 miles per hour.

_____

Compared with real-life experience, and working through the details, this problem makes no sense whatever. Pedaling a bicycle is not like rowing a boat, where the current of the medium directly affects speed.

If you work through the segments of the problem, you find that Juan traveled 40.833 miles with the wind in the first 1.75 hours, so actually finished the race and then some. He spent the next 2.5 hours being blown backward by the wind, even though he was pedaling forward at 11.5 mph. (How much sense does that make?)

The value of 2.704 is .004 because it is 3 spaces to the right of the decimal point.
