Given
h(x) = f(x)·g(x) = -x² -3x +4
Find
Possible equations for f(x) and g(x)
Solution
h(x) factors as -(x -4)(x +1)
There are an infinite number of possibilities for f(x) and g(x). Some of the simpler ones are ...
f(x) = 4 -x; g(x) = x +1
or
f(x) = -x -1; g(x) = x -4
or either of this with f and g swapped.
For some q(x), you can also have ...
f(x) = (4 -x)×q(x); g(x) = (x +1)/q(x)
again, possibly with f and g swapped
Hello!
Explanation:
Slope-intercept form: → 
m: represents the slope and is constant.
b: represents the y-intercept.
Rise/run.
<u><em>Y-intercept is -7</em></u>
<u><em>But the slope is -5.</em></u>
<u><em>Answer: → 0.714</em></u>
Hope this helps!

Answer:
$40
Step-by-step explanation:
x is the original price of the gift
(10% of x) is the value of the discount
(10% of x) = 10/100 . x = 0.1 x
0.1 x is the value of the discount
x - (10% of x) is what was paid, after the discount
x - 0.1 x = 0.9 x
0.9 x is what was paid
4 children paid $9/each
4 times $9 = $36
$36 is the total amount that was paid by the children
$36 = 0.9 x
$36 / 0.9 = x
x = $36 / 0.9 = 360 / 9
x = 40
