Answer:

He missed 14 questions

Step-by-step explanation:

Total = Right + Miss ⇒ t = r + m

Right = Miss + 12 ⇒ r = m + 12

t = 40

Since t = r + m and r = m + 12 then:

t = m + 12 + m

t = 2m + 12

40 = 2m + 12

28 = 2m

m = 14

Trey is taking out a loan for $85000. It is a 20-year loan with an APR of 5.85% what will his monthly payment be?

Answer:

$768.54 (Approximate)

Step-by-step explanation:

Trey is taking out a loan for $85000. It is a 20-year loan with an APR of 5.85%.

Therefore, if we consider the interest rate is simple interest, then using the simple interest formula, the sum will become after 20 years

$85000(1 + \frac{5.85 \times 20}{100}) = 184450$ dollars.

Therefore, the monthly payment for the loan will be $\frac{184450}{20 \times 12} = 768.54$ dollars. (Answer)

Write an equation of the line that passes through the points (-2,-2) and (0,5)

marshall27 [118]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
&&(~ -2 &,& -2~) 
&&(~ 0 &,& 5~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{5-(-2)}{0-(-2)}\implies \cfrac{5+2}{0+2}\implies \cfrac{7}{2}
\\\\\\
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-2)=\cfrac{7}{2}[x-(-2)]
\\\\\\
y+2=\cfrac{7}{2}(x+2)\implies y+2=\cfrac{7}{2}x+7\implies y=\cfrac{7}{2}x+5$

Because
$\frac{f(x)}{x-3} = 2x^{2} + 10x - 1$
therefore
f(x) = (x-3)(2x² + 10x - 1) + k, where k = constant.

Because f(3) = 4, therefore k =4.
The polynomial is
f(x) = 2x³ + 10x² - x - 6x² - 30x + 3 + 4
= 2x³ + 4x² - 31x + 7

Answer: f(x) = 2x³ + 4x² - 31x + 7
