Answer:
(-1,3)
Step-by-step explanation:
Graph the given system of equations
y=-x+2
make a table for each equation to graph it
Lets assume some value for x and find out y
x y=-x+2
-1 -(-1) + 2= 3
0 0+2 = 2
1 -1+2 = 1
Now make a table for second equation
y= 4x+7
Lets assume some value for x and find out y
x y= 4x+7
-1 4(-1) + 7= 3
0 4(0) + 7 = 7
1 4(1) + 7 = 11
The graph is attached below
Solution is (-1,3)

Answer:
C. between 80 and 90
Step-by-step explanation:
430/5=86
Yes because 3² + 4² = 5²
to be sure
9 + 16 = 25
25 = 25
