Answers

Answer 1

Answer:

the first choice 2 ; -2 ; 6 :-6

Step-by-step explanation:

1) method : you can put this values 2 ; -2 ; 6 :-6 you are 0

2) method  you can solve this equation

x^4-40x^2+144=0

let : x² = t   and t ≥ 0

t² -40t +144 = 0

Δ = b²- 4ac    a= 1           b = - 40         c = 144

Δ =(-40)²- 4(1)(144= 1600 -576 = 1024=32²

t1 = (40+32)/2 = 36 = 6²

t1 = (40-32)/2 = 4 = 2²

but :  x² = t   and t ≥ 0

1)case    :    x² = 6²       x = 6 or x= -6

2() case : x² =2²          x = 2 or x= -2

Answer:

(p +5)²  = 26

Step-by-step explanation:

p²+10p = 1

try to arrange them like a²+2ab+b² ;

     

here,

a² = p²  →      ∴a=p

and,

2ab = 10p

⇒2ab = 10a    [∵a=p]

∴ b=5            [dividing both sides by 2a]

∴b²=5²

hence,

⇒ p² + 2 .p.5 + 5² = 1+5²   [add  5² on both sides ]

⇒ (p +5)²  =1+25

∴  (p +5)²  = 26

D) 75

Answers

Answer:

(1).(C) Commutative property.

(4).(D) 3

(3).(D)  75

Step-by-step explanation:

(1) Commutative property of addition states that if two number p and q are real. Then, it doesn't matter in which order the numbers are added it will provide the same result. i.e.

p + q = q + p

Therefore, -8 + (-15) = (-15) + (-8) is an example of commutative property.

(2) - (q+14) = (-3) + (-14)

[tex]\Rightarrow -q - 14=-3 -14[/tex]

[tex]\Rightarrow-q= -17 +14[/tex]

[tex]\Rightarrow-q=-3[/tex]

[tex]\Rightarrow q=3[/tex]

(3) -10 + a + (-15) = 50

[tex]\Rightarrow a -25 = 50[/tex]

[tex]\Rightarrow a = 50 + 25 = 75[/tex]

What is the image point of (9,8) after a translation right 4 units and up 2 units?​

Answers

Answer:

(13,10)

Step-by-step explanation:

On the graph, all the points going right starting from 0, would be positive, and all points going up starting from 0 would be positive.

You should also know that going right would mean the x (which is 9 here) would get bigger; and the y (which is 4) going up would get bigger too.

So if you move (9,8) right 4 times 9 + 4 = 13, so now you have (13,8).

Then, you move (13,8) up 2 units, so 8+2 more units = 10, so then your final answer would be (13,10).

Hope this helped, sorry if its confusing I wasn't born to teach lol

The image point of (9, 8) is (13, 10), after the translation.

What is the required image point ?

In graphs, we know that the horizontal line is the x-axis, more we go right in that line, more positive values of x we get & in similar manner, more we go left, we get more negative values of x.

So, if we translate (9, 8), 4 units in the right, then we get larger value of x, i.e. 9+4=13 and the point becomes (13,8)

Also, the vertical line on a graph defined the y-axis, more we go up in that line, more we get positive values of y and more we go down that line, more we get negative values of y.

So, if we up the value of y 2 units, then the co-ordinate of y is 8+2 = 10

And the point becomes (13,10)

So, the required image point is (13,10)

3w - (7w + 12) = 2(w – 3)

how do u do this step by step​

Answers

Answer:

w=-1

Step-by-step explanation:

3w-7w-12=2(w-3)

1) Combine alike terms:

-4w-12=2(w-3)

2) Use the Distributive property on the left side of the equation:

-4w+12=2w-6

3) Add a 6 to both sides:

-4w-6=2w

4) Add a 4w to both sides:

-6=6w

5) Divide both sides by 6:

w=-6/6

6) Simplify the fraction:

w=-1

The solution to the equation 3w - (7w + 12) = 2(w - 3) is w = -1.

The given equation is 3w - (7w + 12) = 2(w – 3).

Distribute the negative sign (-) to the terms inside the parentheses on the left side and distribute the 2 to the terms inside the parentheses on the right side:

3w - 7w - 12 = 2w - 6

-4w - 12 = 2w - 6

Move all the terms involving w to one side of the equation by adding 4w to both sides:

-4w + 4w - 12 = 2w + 4w - 6

-12 = 6w - 6

Add 6 to both sides of the equation to isolate the term with 6w:

-12 + 6 = 6w - 6 + 6

-6 = 6w

Divide both sides of the equation by 6 to solve for w:

(-6) / 6 = 6w / 6

-1 = w

Therefore, the solution to the equation 3w - (7w + 12) = 2(w - 3) is w = -1.

complement of angle Y. Y=(8x-20°)​

Answers

Answer:

Step-by-step explanation:

Complement = 90 - Angle

Complement = 90 - y

Complement = 90 - (8x - 20)

Complement = 90 - 8x + 20

Complement = -8x + 110

Final answer:

The complement of an angle Y denoted as (8x-20°), is found by subtracting the angle from 90°. After distribution and addition, the final formula for the complement of angle Y is 110° - 8x.

Explanation:

The complement of an angle is defined as the difference between 90 degrees and the angle. In this case, we need to find the complement of angle Y, represented as (8x-20°).

To find the complement, we subtract the angle from 90°. So, the complement of angle Y is given by the formula 90° - (8x - 20°).

When you distribute the negative sign into the parentheses, the formula becomes 90° - 8x + 20°. Adding 90° and 20° gives us 110°, making the final formula for the complement of angle Y as 110° - 8x.

0.099 < 0.101

0.101 - 0.099 = 0.002

If she cuts the paper in half 3 times, she will have 8 pieces.

Suppose that each quarter at a particular community college Jared has to pay $785 in tuition and $23 in fees. If Jared has 2 quarters remaining find the total amount he will need for tuition and fees

Answers

Answer:

he will need exactly $808.75

Final answer:

Jared's total expense for the remaining 2 quarters would amount to $1616, which is the sum of tuition ($785) and fees ($23) per quarter, multiplied by the total remaining quarters (2).

Explanation:

To determine the amount Jared will need for tuition and fees, we first have to calculate the total cost for each quarter. For every quarter, the total cost comprises of $785 in tuition and $23 in fees. Consequently, the overall cost per quarter will be 785 (for tuition) + 23 (fees), which amounts to $808.

Given that Jared still has 2 quarters remaining, the net amount he would require will be the product of the amount needed per quarter and the number of remaining quarters i.e., 808 * 2, therefore equally to $1616.

The corret match is as follows:

Multiplication property of equality: (4x)(1/4) = (3)(1/4)

Addition property of equality : 3x - 4 + 4 = 12 + 4

Subtraction property of equality: (1/2) + 5x -(1/2)=8-(1/2)

Division property of equality: 55/11 = 11x/11.

For multiplication property of equality:

Consider an equation:

4x = 3

Multiply by (1/4) on both sides by this property we get,

(4x)(1/4) = (3)(1/4)

For addition property of equality:

Consider an equation:

3x - 4  = 12
Add 4 both sides we get,

3x - 4 + 4 = 12 + 4

For subtraction property of equality:

Consider an equation:

(1/2) + 5x=8

Subtract both sides by (1/2)

(1/2) + 5x -(1/2)=8-(1/2)

For division property of equality:

Consider an equation:

55= 11x

Divide both sides by 11 we get,

55/11 = 11x/11.

Hence,

The corret match is:

Multiplication property of equality: (4x)(1/4) = (3)(1/4)

Addition property of equality : 3x - 4 + 4 = 12 + 4

Subtraction property of equality: (1/2) + 5x -(1/2)=8-(1/2)

Division property of equality: 55/11 = 11x/11.

They added enzymes to the heat-killed S strain to target different types of molecules in each test. If they had then injected the different mixtures into mice, what would the results have been? Bryan took a taxi home from the opera. The taxi fare was $2.50 per mile, and he gave the driver a tip of $3. Bryan paid a total of $35.50. The equation 2.50x + 3 = 35.5 can be used to find the distance in miles (x) between the opera house and Bryan's home.How many miles is it between the opera house and Bryan's home? Part A Calculate the freezing point of a solution containing 5.0 grams of KCl and 550.0 grams of water. The molal-freezing-point-depression constant (Kf) for water is 1.86 C/m.
