Find the x intercepts of thr following parabola y= -4x^2 + 8x +12
2 answers:
For this case we must find the x-intersepts values of the following equation:
Doing y = 0 we have:
Dividing between -4 on both sides of the equation:
We factor, we look for two numbers that when multiplied by -3 and when added by -2. These are -3 and 1:
Thus, the x-intercepts values are:
Answer:
Answer:
x=-1 or x=3
Step-by-step explanation:
This is a quadratic equation
You can use the graph tool to visualize the x-intercepts on the graph as attached below.

Answer:
13 and 27
Step-by-step explanation:
x+y=40
x- smaller
2y-x=41
x=2y-41
Now to plug it into our first equation:
3y-41=40
3y=81
y=27
x=13
