Answer:
first car = 35, second car= 15
Step-by-step explanation:
40x+15y=1625
x+y=50
multiplying the 2nd by -15 and add the 2 equations, we get x= 35 and by substituting on second equation we get y= 15
Answer: $19.60
Step-by-step explanation:
24.50 x 20% or (.20)= 4.90
24.50-4.90=19.60
$19.60 is the answer
Answer:
y = -2x + 5
Step-by-step explanation:
Assuming this is linear, the slope would be constant. For every 1 x, y decreases by 2. This means that the slope is -2.
y = -2x + b
Now all we need is the y-intercept.
If we plug in the first point (1,3), we get:
3 = -2*1+b
3 = -2+b
b = 5
This is the y-intercept.
y = -2x + 5
Answer:
x=6
Step-by-step explanation:
8x-11=37
Add 11 to both sides
8x=48
Divide 8 from both sides
x=6
