Answer:

41,44

Step-by-step explanation:

make the width x. lenght = x+3.

so, the perimeter will be x+x+3+x+x+3=170.

Simplifiyng, 4x+6=170

subtract six from both sides. Get 4x=164

Divide by 4. Get x=41

add three. Get length = 44

Write an equation of the line that passes through (2, 2) and is parallel to the line y = 7x

zimovet [89]

Answer:

y = 7x - 12

Step-by-step explanation:

Parallel lines have same slope.

y = mx + b

m - > slope & b -> y-intercept

y = 7x

So, slope = 7 & (2 , 2)

y - y1 = m(x -x1)

y - 2 = 7(x - 2)

y - 2 = 7x - 14

y = 7x - 14 + 2

y = 7x - 12

Please be quick! i need answer for each in the box, giving 15 points

The solutions are $f(-2)=12, f(-1)=7, f(0)=2, f(1)=-3$ and $f(2)=-8$

Explanation:

To find the values of f(x), we need to substitute the values for x in the function $f(x)=2-5x$

For $x=-2$ ,

$\begin{aligned}f(x) &=2-5 x \\&=2-5(-2) \\&=2+10 \\&=12\end{aligned}$

Thus, $f(-2)=12$

For $x=-1$ ,

$\begin{aligned}f(-1) &=2-5(-1) \\&=2+5 \\&=7\end{aligned}$

Thus, $f(-1)=7$

For $x=0$ ,

$\begin{aligned}f(0) &=2-5(0) \\&=2+0 \\&=2\end{aligned}$

Thus, $f(0)=2$

For $x=1$ ,

$\begin{aligned}f(1) &=2-5(1) \\&=2-5 \\&=-3\end{aligned}$

Thus, $f(1)=-3$

For $x=2$ ,

$\begin{aligned}f(2) &=2-5(2) \\&=2-10 \\&=-8\end{aligned}$

Thus, $f(2)=-8$

Hence, the solutions are $f(-2)=12, f(-1)=7, f(0)=2, f(1)=-3$ and $f(2)=-8$
