The answer is $5.25 or .75 cents each
Answer:
(4, 26)
(-6, -24)
Step-by-step explanation:
Step 1: Substitution
5x + 6 = x² + 7x - 18
Step 2: Move everything to one side
0 = x² + 2x - 24
Step 3: Factor
(x - 4)(x + 6) = 0
Step 4: Find roots
x = 4, -6
Step 5: Plug in <em>x</em> to find <em>y</em>
y = 5(4) + 6
y = 20 + 6
y = 26
y = 5(-6) + 6
y = -30 + 6
y = -24
find the slope, or "rate of change", then plug those values in the
point-slope form and solve for "y", to get the equation of that line,
how much is it for 73 minutes? well, make x = 73, and to get "y" :)
It should be 2 but i’m not positive
