Answer: A
Explanation:
Just use substitution because it's more efficient. Plug -2x-8 into y to make -2x-8=3x+2. Add 8 to both sides to get -2x=3x+10. Subtract 3x to both sides to get -5x=10. Divide -5 to both sides to get x=-2. Now, plug in x=-2 to one of the equations, let's use y=3x+2. The equation would be y=3(-2)+2. Multiply 3 and -2 to get -6. Add -6 to 2 and you'll result with y=-4.
This problem can simply be expressed in an equation. Let's say that x is the amount of sales that is being looked for here. So our equation will be 0.03x = 180. So to put it simply, the amount of sales (x) has to be multiplied by 0.03 in order to get 180. So to solve for x, all we have to do now is divide 180 by 0.03. If we do that, we will be able to get a final answer of 6,000. So we can conclude that the total amount of sales received by the salesperson is 6,000.
I can't graph the function but I can tell you that the equation is y= 20 + 2x
The values are a = 7, b = -9, c = -18.
<u>Step-by-step explanation:</u>
The given quadratic equation is 
The general form of the quadratic equation is 
where,
- a is the coefficient of x².
- b is the coefficient of x.
- c is the constant term.
Now, you have to modify the given quadratic equation similar to the general form of quadratic equation.
So, bring the constant term 18 to the left side of the equation for equating it to zero.
⇒ 
Compare the above equation with general form
⇒ a = 7
⇒ b = -9
⇒ c = -18
Therefore, the values of a, b, and c are 7, -9 and -18.
Answer:
B) 4
Step-by-step explanation:
(f-g)(x) = x² - 4x - 1
5² - 4(5) - 1 = 4
