Answer:
Step-by-step explanation:
a) The relative minimum of the function from the graph is -18 at x=0.
b) The graph ends with two arrows which means it continues from there indefinitely. So the function increases from x equal to negative infinity to -2 and then from 0 to +2.
Answer:
Step-by-step explanation:
The correct question is
Zena needs a salesperson. Salesperson A is offering his services for an initial $50 in addition to $5 per hour. salesperson B is offering her services for an initial $40 in addition to $7 per hour. When will the two coaches charge the same amount of money?
Let
x ----> the number of hours
y ----> the total charge
we know that
Salesperson A
------> equation A
Salesperson B
------> equation B
To find out when the two coaches charge the same amount of money, equate equation A and equation B and solve for x
7x+40=5x+50
7x-5x=50-40
2x=10
<h2>x=5 hours i think just im not sure but i tried</h2>
Y - y1 = m(x - x1)
slope(m) = -56
(8,-4)...x1 = 8 and y1 = -4
now we sub...pay close attention to ur signs
y - (-4) = -56(x - 8)....not finished yet
y + 4 = -56(x - 8) <===
