Answer:
([tex]\frac{31}{4} , \frac{-1}{8}[/tex])
Step-by-step explanation:
use substitution:
3x+2y=23
x=2y+8
plug in 2y+8 for x
3(2y+8)+2y=23
distribute:
6y+24+2y=23
combine like terms:
8y+24=23
solve the equation:
y=-1/8
substitute -1/8 for y:
x=2(-1/8)+8
solve the equation:
x=31/4

What’s the area of this figure?
Answer:
374 mm
Step-by-step explanation:
There are two rectangles and one triangle. This means that we need to add the sum of two rectangles and one triangle together.
Rectangle 1:
19*9=171
Rectangle 2:
19*9=171
Triangle:
8*23*1/2=32
(We divide by 1/2 because it's a triangle)
Now we add them together.
171+171+32=374
In the end, the answer is 374. I didn't show all of my work because most of it was done mentally.
