Answer:

x = 3 , y = 0

Step-by-step explanation:

Solve the following system:

{y = (2 x)/3 - 2 | (equation 1)

y = 3 - x | (equation 2)

Express the system in standard form:

{-(2 x)/3 + y = -2 | (equation 1)

x + y = 3 | (equation 2)

Swap equation 1 with equation 2:

{x + y = 3 | (equation 1)

-(2 x)/3 + y = -2 | (equation 2)

Add 2/3 × (equation 1) to equation 2:

{x + y = 3 | (equation 1)

0 x+(5 y)/3 = 0 | (equation 2)

Multiply equation 2 by 3/5:

{x + y = 3 | (equation 1)

0 x+y = 0 | (equation 2)

Subtract equation 2 from equation 1:

{x+0 y = 3 | (equation 1)

0 x+y = 0 | (equation 2)

Collect results:

Answer: {x = 3 , y = 0

To solve the given system of equations, we can use the method of substitution. After obtaining the value of x, we can substitute it back into one of the original equations to solve for y. The solution to the system is x = 3 and y = 0.

The given system of equations is:

y = \frac{2}{3}x - 2

y = -x + 3

To solve this system, we can use the method of substitution. We can rearrange the second equation to solve for y:

y = -x + 3

Now, substitute this value of y into the first equation:

\frac{2}{3}x - 2 = -x + 3

Add x to both sides:

\frac{2}{3}x + x - 2 = 3

Multiply both sides by 3 to eliminate the fraction:

2x + 3x - 6 = 9

Combine like terms:

5x - 6 = 9

Add 6 to both sides:

5x = 15

Divide both sides by 5:

x = 3

Now, substitute the value of x back into one of the original equations to solve for y:

y = -x + 3

y = -3 + 3

y = 0

Therefore, the solution to the system of equations is x = 3 and y = 0.

Answer:

6 cm

Step-by-step explanation:

circumference = 3.14 times the diameter, which is half of the radius.

I think you meant 36.7 cm

if you divide 36.7 by 3.14, you get the diameter (11.687). half of that is 5.843cm.

Answer:

C 2.226 times 10^8

Step-by-step explanation:

5.3* 10^4    * 4.2 * 10^3

We multiply the numbers out front

5.3* 4.2 =22.26

We add the exponents

10^(4+3) = 10^7

22.26*10^7

But we are not done yet because The number out front has to be between 1 and less than 10

Move the decimal 1 place to the left and add 1 to the exponent

Answer:

36.6 or 36.61

Step-by-step explanation:

the first thing you want to do is add all your numbers together.

57+28+19+19+26+54+88+65+13+10+18+50+29

this would equal 476

the second thing you do is divide your total by the amount of numbers in your equation:

476/13

which would equal:

36.6153846

Lastly, you round to the tenth place, if the number in the second place after the decimal is under 5, the number before stays the same(if its above 5 you would round up). Since the second number after the decimal is under 5 it stays the same

your answer would be 36.6 or 36.61.

I hope this helped! sorry if i messed up its been a while.

Final answer:

To find the average of a list of numbers, add all the numbers and divide by the total count. In this case, the average of the numbers provided is 36.6 when rounded to the nearest tenth.

Explanation:

Given numbers = 57 28 19 19 26 54 88 65 13 10 18 50 29

To calculate the average of a list of numbers, you need to add all the numbers together and then divide by the total count of numbers.

Add all the numbers in the list: 57 + 28 + 19 + 19 + 26 + 54 + 88 + 65 + 13 + 10 + 18 + 50 + 29 = 476

Divide the sum by the total count of numbers in the list: 476 ÷ 13 = 36.6

Rounded to the nearest tenth, the average of the list of numbers is 36.6

The length of the radius of the circle is 3.45 unit.

We all know that a circle's radius is the distance a point on the circle's circumference travels from its centre.

The circle's diameter is a straight line that passes through its centre and has its endpoints on the circle.

Radius is therefore equal to half of diameter.

From the figure we have,

Diameter = 6.9 unit

Now, using the relation

Diameter = 2 x radius

6.9 = 2 x  radius

radius = 6.9/ 2

radius = 3.45 unit

Answer:

D. $9.50

Step-by-step explanation:

In total, Jeff spends 21/40 of his money. (1/8+2/5=21/40)

He has 19/40 left.

19/40*20=380/40=9.5

First, let's put 2/5 and 1/8 into similar fractions, in that they have the same denominator.

2/5 = 16/40

1/8 = 5/40

Then, we'll add the fractions together.

16/40 + 5/40 = 21/40

So, Jeff spent 21/40 of his money. We can set up a proportion to find the amount that Jeff spent.

x/20 = 21/40

420 = 40x

x = 10.50

Finally, we'll subtract the amount that Jeff spent from the original amount.

20 - 10.50 = 9.50

Jeff has D. $9.50 left.

Answer:

A, C, and D

Step-by-step explanation:

The rate of change will simply be the slope of the line, which we can find by taking the change in y and dividing that by the change in x:

slope = [tex]\frac{6-3}{4-2} =\frac{3}{2}[/tex]

Thus, the slope is 3/2 = 1.5.

Since the slope remains constant throughout the graph, we know that A is correct. In addition because the points 0, 2, 4, and 6 are on the graph, the rate of change between any of the two points will still be the constant 1.5, making C and D correct as well.

So, we can choose A, C, and D.

Hope this helps!

Answer:

The rate of change of a linear function is always the same.

The rate of change from 2 years to 4 years on the graph is 1.5 inches per year.

The rate of change from 0 years to 6 years on the graph is 1.5 inches per year.

Step-by-step explanation:

Slope = rate = (6 - 3)/(4 - 2) = 3/2

Slope of a straight line is constant hence the rate of change is also constant

Answer: It would take 6 trips

Step-by-step explanation: The pile of earth has formed into a cone with the following dimensions, height is 9 feet and base diameter is 24 feet across.

However the haulage truck has its capacity measured in yards, and so we use a standard rate of conversion of yards to feet and vice versa. The standard rate is;

1 Yard = 3 Feet

Hence, the height of the pile of earth an now be given as;

h yards = 9/3

h yards = 3

height = 3 yards

Similarly, the the base of the pile of earth can be calculated as;

(Note that the radius is derived as diameter divided by 2, that is 24/2)

r yards = 12/3

r yards = 4

radius = 4 yards

The volume of a cone is given as;

Volume = πr²h/3

Volume = 3.14 x 4² x (3/3)

Volume = 3.14 x 16

Volume = 50.24 cubic yards

For a haulage truck that can haul 9 cubic yards per trip, the total number of trips required to haul the entire volume of dirt is given as follows;

No of trips = 50.24 ÷ 9

No of trips = 5.5822

No of trips ≈ 6

Therefore it would take the truck 6 trips to haul the entire pile of earth.

Answer:

6 trips

Answer:

3 square units branliest pls

Step-by-step explanation:

The correct answer is option A. The estimated area of the circle is 3 square units.

To estimate the area of a circle, we use the formula for the area of a circle:

[tex]\[ A = \pi r^2 \][/tex]

where [tex]\( r \)[/tex] is the radius of the circle. Given that the diameter of the circle is 2 units, we can find the radius by dividing the diameter by 2:

[tex]\[ r = \frac{d}{2} = \frac{2}{2} = 1 \text{ unit} \][/tex]

Now, we substitute the radius into the area formula:

[tex]\[ A = \pi (1)^2 = \pi \][/tex]

Using the value of [tex]\(\pi \approx 3.14\)[/tex], we get:

[tex]\[ A \approx 3.14 \][/tex]

Rounding 3.14 to the nearest whole number, we get:

[tex]\[ A \approx 3 \][/tex].

The complete question is:

Estimate the area of the circle, given the diameter as 2 unit. Round to the nearest whole number.

Answer:

85 flu patients Per week so A

Step-by-step explanation:

Final answer:

Using the two given points during the flu season, we calculate the slope of the reduction in patients per week and use one of the points to find the y-intercept. The resulting linear equation representing the number of patients seen each week at the clinic is f(x) = -5x + 100, which corresponds to option B.

Explanation:

To find the function that represents the number of patients seen each week during flu season at a medical clinic, we can use the two data points provided: In week 5, there were 75 patients (point 1: (5, 75)), and in week 10, there were 50 patients (point 2: (10, 50)). The goal is to find a linear equation of the form f(x) = mx + b, where m is the slope of the line and b is the y-intercept.

First, we find the slope (m) using the formula:

m = (Y2 - Y1) / (X2 - X1)

Substituting the given values, we get:

m = (50 - 75) / (10 - 5) = -25 / 5 = -5

Now we use one of the points to find the y-intercept (b).

Using point (5, 75):

75 = (-5)(5) + b

75 = -25 + b

b = 75 + 25

b = 100

So the equation of this function in function form is:

f(x) = -5x + 100

Therefore, the correct option is B. f(x) = -5x + 100.
