Answer:
<h2>x = 3, y = 2</h2>
Step-by-step explanation:
<u>Graph 1</u>
coordinates : (0,-5) (-6,-2)
m = (y2-y1)/(x2-x1)
m = (-2-(-5))/(-6-0)
m = 3/-6 = -1/2
Substitute the values,
y = mx + c
-2 = (-1/2)(-6) + c
-2 = 3 + c
c = -5
Thus, equation is y = -1/2x -5
<u>Graph </u><u>2</u>
coordinates : ( 4,-2) (-5,3)
m = (y2-y1)/(x2-x1)
m = (3-(-2))/(-5-4)
m = 5/-9
Substitute the values,
y = mx + c
-2 = (-5/9)(4) + c
-2 = -20/9 + c
c = 2/9
Thus, the equation is y = -5/9 + (2/9)
Hope it helps :)
Answer: 2 deliveries per hour
Step-by-step explanation:
Make an equation:
J = 1/2F - 10
Where 'J' represents Justin's age and 'F' represents his Father's age.
Plug in 12 for J:
12 = 1/2F - 10
Add 10 to both sides:
22 = 1/2F
Divide 1/2 to both sides or multiply by its reciprocal, 2:
F = 44
I think the answer is B. But if I’m wrong I am so sorry :(
