3 0

Answer:

A

Step-by-step explanation:

Start with variable x.
4x - 6y = 28
Substitute the variables for numbers.
4(1) - 6(-4) = 28
Solve the new equation
4 + -24 = 28

Move to the second equation with variable y.
8x - 4y = 24
Substitute variables
8(1) - 4(-4) = 24
Solve
8 - (-16) = 24

The answer is A, x = 1, y = -4

What is the area of the figure to the nearest hundredth renter the answer in the box 2yd 4yd
Norma-Jean [14]

Answer:

9.57 yd squared

Step-by-step explanation:

we can divide this figure into two shapes:  a rectangle and a semi-circle

since we know the length and width of the rectangle, all we ahve to do is multiply them together to find the area: <u>8 yd squared</u>

for the semi-circle, we know the area is \frac{\\\pi r^2}{2\\}

raduis is half the diameter so 1 yd

\frac{3.14(1)^2}{2}

\frac{3.14}{2}<u />

<u>1.57 yd squared</u>

lastly, add the area of the two figures together 8+1.57
