5x+8=-27
8 more means addition. -27 would be total. 5 times the number ( in this case x) would mean multiplication.
one solution i think it has one solution
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:
y-intercept: [0, -2]; 0 = m
Step-by-step explanation:
Anything set to equal <em>y</em><em> </em>is what is known as a zero <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] because it is a horizontal line.
