Answer:
$51.2
Step-by-step explanation:
3 + 4 + 1 = 8
8 x 6.40 + 51.2
Answer:
x = 1, y = 10
Step-by-step explanation:
y = -5x + 15 --- Equation 1
2x + y = 12 --- Equation 2
Substitute y = -5x + 15 into Equation 2:
2x + y = 12
2x - 5x + 15 = 12
Evaluate like terms.
15 - 3x = 12
Isolate -3x.
-3x = 12 - 15
Evaluate like terms.
-3x = -3
Find x.
x = -3 ÷ -3
x = 1
Substitute x = 1 into Equation 2:
2x + y = 12
2(1) + y = 12
2 + y = 12
Isolate y.
y = 12 - 2
y = 10
Answer:
y=9
Step-by-step explanation:
Slope: 9-9/-2-15=0
Therefore, y=0x+b
Plug values in: 9=0(-2)+b
0+b=9
b=9
Therefore, equation is y=9
