ANSWER THESE TWO QUESTIONS PLEASE THANK YOU

Arturiano [62]

Answer:

1) $63.60

2) y=8x-6

Step-by-step explanation:

1) $233.20 divided 11 hours is a hourly rate of $21.20. $21.20 multiplied by 3 hours is $63.60.

2) To find the slope you need $\frac{y_{2} -y_{1}}{x_{2}-x_{1}}$ . (10-2)/(2-1) is 8. The slope is 8. So you have y=8x+b. To find b just plug in a point and solve. 2=8(1)+b. B= -6. y=8x-6

What is (f−g)(x)?

Oxana [17]

Answer:

$\large\boxed{(f-g)(x)==3x^5-2x^4-x^2+x-21}$

Step-by-step explanation:

$(f-g)(x)=f(x)-g(x)\\\\\text{We have}\\\\f(x)=3x^5+6x^2-5\\\\g(x)=2x^4+7x^2-x+16\\\\\text{substitute:}\\\\(f-g)(x)=(3x^5+6x^2-5)-(2x^4+7x^2-x+16)\\\\=3x^5+6x^2-5-2x^4-7x^2+x-16\\\\\text{combine like terms}\\\\=3x^5-2x^4+(6x^2-7x^2)+x+(-5-16)\\\\=3x^5-2x^4-x^2+x-21$
