Substitute y = 1/5 x + 1 into x + 5y = -15

x + 5y = -15

x + 5(1/5 x + 1) = -15

x + x + 5 = -15

2x = -20

x = -10

Plug in x = -10 into y = 1/5 x + 1

y = 1/5 (-10) + 1

y = -2 + 1

y = -1

(-10 , -1)

Answer is the last one

(-10 , -1)

Monica has a 24

melamori03 [73]

Answer:

The fraction of frame did Monica paint blue is $\frac{3\sqrt{6}}{2}$

Step-by-step explanation:

Given as :

The area of square frame = A = 24 square inches

Monica paint $\frac{3}{4}$ of one side of the frame blue

Let the measure of one side of frame = x

So, <u>From Area of square</u>

Area = side × side

Or, A = x × x

Or, x ² = 24

∴ x = $\sqrt{24}$ = 2 $\sqrt{6}$

So, Measure of each side = x = 2 $\sqrt{6}$

Now, As Monica paint $\frac{3}{4}$ of one side of the frame blue

So, The painted part = $\frac{3}{4}$ × 2 $\sqrt{6}$

∴ The painted part = $\frac{3}{2}$ × $\sqrt{6}$

I,e The fraction of painted blue = $\frac{3\sqrt{6}}{2}$

Hence, The fraction of frame did Monica paint blue is $\frac{3\sqrt{6}}{2}$ Answer
