Answer:
A. x=0 and x=4
Step-by-step explanation:
The roots of a quadratic function are the x intercepts of the parabola. In this case, the roots are 0 and 4 because the parabola intercepts the x axis twice in these points.
Your answer is A. x=0 and x=4
Hope I helped!
Answer:
8
2
0
2
8
Step-by-step explanation:
f(x)=2x^2
f(x)=y
y=2x^2
y=2(-2)^2
y=2(4)
y=8
y=2x^2
y=2(-1)^2
Y=2
Y=2X^2
y=2(0)^2
y=0
y=2x^2
y=2(1)^2
y=2
y=2x^2
y=2(2)^2
y=8
DON'T FORGET BODMAS
The problem statement gives you the relationship between their speeds, and it gives you information you can use to find their total speed. You solve this by finding the total speed, then the proportion of that belonging to Bill.
The total speed is (120 mi)/(3 h) = 40 mi/h.
The speed ratio is ...
... Bill : Joe = 3 : 1
so the speed ratio Bill : Total is ...
... 3 : (3+1) = 3:4.
Bill's speed is (3/4)×(40 mi/h) = 30 mi/h.
Answer:
I assume your goal is to rationalize the denominator -
So you need to multiply the denominator by its conjugate.
So we have:
->
gg
<span>y-intercept when x = 0
</span>so
y = -7x + 1
y = -7(0) +1
y = 1
