U have given half of the question, I mean, do we have to find something or what? please mention :)
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.
It’s 12/16 and 8/12 because if you subtract 12/16 with 4/4 than you’ll get 8/12
Answer:
see the explanation
Step-by-step explanation:
Let
x -----> the number
we know that
Three-eighths multiplied by a number plus one must be equal to 11
so
The linear equation that represent this situation is
Solve for x
Subtract 1 both sides
Multiply by 8/3 both sides
The number is 80/3
