35 pages are read. 56 divided by 8 equals 7 so 7 multiplied by 5 is 35.
Step-by-step explanation:
First, since this is already in factored form, we can find the zeroes of this quadratic, which are -3 and -1/2. (To check, you can try plugging in these 2 values for x, and they indeed equal to zero.)
Now, we want to find the vertex. The x value would be exactly halfway between -3 and -1/2, which is -1.75. Now, we just need to evaluate it, so we can find the y value of the vertex:
(-1.75+3)(2*(-1.75)+1)
=(1.25)(-2.5)
=(-3.125)
Therefore, the vertex is at (-1.75, -3.125).
3 points define a parabola, so we can directly graph it now(graph attached to the answer).
I hope this helped.
Answer:
1/6
Explain:
The reciprocal of the slope is its perpendicular.
6/1 --> 1/6
x=-½ y=0
Step-by-step explanation:
y=2x+1
y=6x-1. this means that
2x-1=6x+1
2x-6x=1+1.
-4x=2. divide both sides by -4
x=-½
thus y=2x-1
y=1-1
y=0
