11 is 97
12 is -7
13 is 75
14 is 2
15 is -40
I think there is a mistake in 16
17 is 13
18 is 5
Answer:
Step-by-step explanation:
3x + 6 = 2x
3x - 2x = -6
x = -6
Answer:
The next step is draw a line connecting the point F and the point lies on ray l.
First, we have to realize that this is factored form, so we have to put this in standard quadratic form using FOIL, which is a rule mandating how we multiply the numbers here. F stands for First, which means the first number inside the parentheses for both of them, then O means the first number in the first quantity(fancy word for parentheses) multiplied by the last number of the second quantity, and so forth. When you are done, you combine like terms
anyway, you end up with x²-12x-189, but you have to inverse all numbers because of the parentheses in front, so it becomes -x²+12x+189.
Now you can find the axis of symmetry uisng the equation -b=2a (oh yeah, I forgot to mention: the standard quadratic form is a(x)²+b(x)+c already). So you do -12 / -2, which then becomes 6.
The axis of symmetry is 6
<h3>Philipe has to make a weekly sales of $ 3000 so that he can earn $ 360</h3>
<em><u>Solution:</u></em>
Given that,
Philipe works for a computer store that pays a 12% commission and no salary
We have to find his weekly sales have to be for him to earn $360
From given, we can say,
12 % of weekly sales will earn him $ 360
12 % of weekly sales = 360
Let "x" be the weekly sales
12 % of "x" = 360
Solve the above expression
Thus Philipe has to make a weekly sales of $ 3000 so that he can earn $ 360
