Answer:
98 : 15 = 6 R 8
She can pay for six months 6*15 = $90 and she will have $8 left.
Answer:
<em>(a). P(x) = 8x - 112,000 </em>
<em> (b). $80,000 </em>
Step-by-step explanation:
(a). P(x) = R(x) - C(x)
P(x) = 50x - 112,000 - 42x
<em>P(x) = 8x - 112,000</em>
(b). P(24,000) = 8(24,000) - 112,000 = <em>80,000</em>
----------------------------------------
(a). <em>P(x) = 8x - 112,000</em>
Answer:
The value of x that makes the equation equal to 0 is -2.
Step-by-step explanation:
In order to find this, we first must create the composite function using the designated operation. The operation is addition, so we just add them together.
f(x) + g(x) = (f+g)(x)
(x^2 - 2x) + (6x + 4) = (f+g)(x)
x^2 + 4x + 4 = (f+g)(x)
Now, in order to find when this is equal to 0, we need to factor.
x^2 + 4x + 4 = 0
(x + 2)(x + 2) = 0
When it is fully factored, we can set each parenthesis equal to 0 in order to find the value. Since the parenthesis are exactly the same, we only have to do this once.
x + 2 = 0
x = -2
