Equation:
----------------------------------------------------------------
y= -4x² <span>+ 16x - 7
</span>----------------------------------------------------------------
<span>Find x-intercept:
</span>----------------------------------------------------------------<span>
At x-intercept, y = 0
</span> -4x² + 16x - 7 = 0
(7 - 2x) (2x - 1) = 0
----------------------------------------------------------------
Apply zero product property:
----------------------------------------------------------------
(7 - 2x) = 0 or (2x - 1) = 0
x = 3.5 or x = 0.5
----------------------------------------------------------------
Answer: The x-intercept are (3.5, 0) and (0.5, 0).

Answer:
45=32+13
Step-by-step explanation:
because you need to get 45 on the other side to balance it out
cheap answer is, you <u>multiply one fraction by the other's denominator</u>, so let's do that with both of these fellows.
