3 0

Answer and Explanation:

The line seems to pass trough the points (0,6) and (-3,4).

Slope is: $m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{4-6}{-3-0} =\frac{-2}{-3} =\boxed{\frac{2}{3}}$

The slope of the line should be $\frac{2}{3}$ .

Ethan surveyed 120 registered voters at random out of a total of 12,600 registered voters in town. He asked them who they planne

krek1111 [17]

Answer:

Based on the results of the survey, the total number of registered voters expected to vote for Ms. Gibson in the upcoming election are 4725 votes

Step-by-step explanation:

Ms. Gibson has 45 votes of 120 votes

let Ms. Gibson vote of 12,600 be x

45 120

x 12600

cross multiply

120x = 45 x 12600

120x = 567,000

Divide all through by 120

x = 567000 / 120

x = 4725

Based on the results of the survey, the total number of registered voters expected to vote for Ms. Gibson in the upcoming election are 4725 votes

300% = 45 x 3 = 135
45 + 135 = $180

180 x 0.8 = $144

Let f(x)= x^2-4x-c. Find a nonzero value of c such that f(c)=c.

Dimas [21]

Answer:

The nonzero value of c will be:

$c = 6$

Step-by-step explanation:

Given the function

$f\left(x\right)=\:x^2-4x-c$

$f\left(c\right)=\:c^2-4c-c$

$f(c) = c$

$c=\:c^2-4c-c$

switching the sides

$c^2-4c-c=c$

subtract c from both sides

$c^2-4c-c-c=c-c$

$c^2-6c=0$

$c\left(c-6\right)=0$

Using the zero factor principle

$\:If}\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)$

$c=0\quad \mathrm{or}\quad \:c-6=0$

so, the solutions to the quadratic equations are:

$c=0,\:c=6$

Therefore, a nonzero value of c will be:

$c = 6$
