Answer:
Step-by-step explanation:
y - 8 = 2(x - 2)
y - 8 = 2x - 4
y = 2x + 4
15c=m
15 x (amount of cars) = amount of money
Answer:
in one hour = 567÷9
= 63
hence, to drive 315 miles he would need = 315×63 hours

If there is any kind of suspicious mistake
then sorry
You can reconstitute the equation of this quadratic function
of te form:y = ax² + bx + c, by giving x and y the various values in the table. For instance: for x = 0, y =1. Plug 0 & 1 in the equation:1 = a(0)² +b(0) + c → c = 1 . You continue with the other values and you will find :
a-b = -3 and
4a - 2b =- 4
Solving it will give y = x² +4x +1
This is a parabola opening upward (because a >0) with an axis of symmetry = -b/2a or x= -2 and a minimum y = (-2)² -2(4)+1 = -3; hence
MINIMUM (-2, -3).
N.B: Your various answers don't mention my result. However in your
C. Answer they are claiming Maximum (-2,-3) and it's wrong it should be MINIMUM.
Please refer to your teacher since I am sure of the result <span> </span>
