Answer:
Green graph: y = 5x + 2
Red Graph: y = 3x + 3
Blue graph: y = 2x + 3
Step-by-step explanation:
M is the slope, so, y=mx or y=2x. If y is 8 then x is 4.
y=6 x=r
6÷2=3, so r=3.
hope this helps and sorry if it got confusing.
Hello
I have done this before and Nothing further can be done.
Hope this helps
Answer:
$19.23
Step-by-step explanation:
First, add the prices of all 5 comics together. That should equal $17.63. The tax is 9% so that would be 1.5867 or $1.60. In total, Sami paid $19.23.
Step-by-step explanation:
the function actually is
y = 40(x - 1) + 70 = 40x - 40 + 70 = 40x + 30
still, the slope (the factor of x) is 40.
that means y (the cost) increases by 40 for every additional hour (x increases by 1).
so, the rate of change (slope) is 40/1 = $40 per hour.
