Answer:

4.2 is your answer rounded to the nearest tenth.

Step-by-step explanation:

8/17 is equal to 0.470588235294.

In order to make an equivalent fraction with 9 as the denominator, divide 9 by 17 to get 0.529411764705.

Then, multiply 0.529411764705 by 8 to get 4.235294117647.

4.235294117647 is our u.

Simplified to the nearest tenth it is 4.2.

we can double check our answer by taking 4.235294117647 divided by 9. You should get 0.470588235294.

Hope this helps!

Slope-intercept form of Slope = -9/5, y-intercept = -4

Brilliant_brown [7]

Answer:

y = - $\frac{9}{5}$ x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - $\frac{9}{5}$ and c = - 4 , thus

y = - $\frac{9}{5}$ x - 4 ← equation of line

Answer:

15 -1

12 0

9 1

6 2

3 3

0 4

Step-by-step explanation:

This is a function table. For a linear function, find the average rate of change between the listed points called slope. Then use the slope to fill in other inputs and outputs for the function.

$m = \frac{y_2-y_1}{x_2-x_1}=\frac{4-0}{0-12} =\frac{4}{-12} =- \frac{1}{3}$

This means for every 3 units made in the input, the function moves down 1 output.

The perimeter of a rectangular pool is 414 meters. The length is 7 meters more than 4 times the width find the length and width

Marina86 [1]

Answer:

The length of rectangular pool is 167 meters and the width is 40 meters

Step-by-step explanation:

Let

x ----> the length of rectangular pool

y ----> the width of rectangular pool

we know that

The perimeter of rectangle (rectangular pool) is equal to

$P=2(x+y)$

we have

$P=414\ m$

$414=2(x+y)$

simplify

$207=x+y$ ----> equation A

$x=4y+7$ ----> equation B

solve the system by substitution

substitute equation B in equation A

$207=4y+7+y$

solve for y

$207-7=4y+y$

$200=5y$

$y=40\ m$

Find the value of x

$x=4y+7$

$x=4(40)+7=167\ m$

therefore

The length of rectangular pool is 167 meters and the width is 40 meters
