Answer:
y=-1/5x-8/5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-2-(-1))/(2-(-3))
m=(-2+1)/(2+3)
m=-1/5
y-y1=m(x-x1)
y-(-1)=-1/5(x-(-3))
y+1=-1/5(x+3)
y=-1/5x-3/5-1
y=-1/5x-3/5-5/5
y=-1/5x-8/5
(4x-6)/3=8
4x-6=24
4x=30
x=7.5 or x=30/4
Answer:
85 = 5x + 20 is the inequality.
Step-by-step explanation:
Why is it right? Because I said so.
Just kidding. Here:
The cost of the games, 5, is multiplied by x, which is the amount of games that Angel will buy. To solve:
Subtract 20 from both sides:
65 = 5x
Divide 65 by 5.
The answer of the question is: Angel can buy 13 games. (Angel! That's a waste of 65 bucks!)
Answer:
The answer is 1470 seconds.
Step-by-step explanation:
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.
