Answer:
27 and 23
Step-by-step explanation:
x + y = 50
x - y = 4
2x = 54
x = 27
y = 23
Answer:
f86
Step-by-step explanation:
f36
Answer:
y+9=1/5(x+3)
Step-by-step explanation:
Point slope formula: y-y1=m(x-x1)
slope=m
m=1/5
-3=x1 -9=y1
y-(-9) =1/5(x-(-3))
simplify...
y+9=1/5(x+3)
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
y-----> the cost of fuel
x-----> the number of gallons
we know that
The linear equation that represent this situation is equal to

This linear equation represent a direct variation, because the y-intercept is equal to zero ( the line passes through the origin)
using a graphing tool
see the attached figure
