Answer:

1.5

Step-by-step explanation:

of the similar shapes you are only given the lengths of two corresponding sides, 22mm and 33mm

if you do 33/22 you get 1.5 so your scale factor is 1.5

(in order to go from the original shape to the copy times by 1.5, and divide if you know the length of the copy and want to work out the original)

-6 - 3(2x + 4) = 18what’s the answer

Brrunno [24]

Answer:

$x=-6$

Step-by-step explanation:

$-6-3\left(2x+4\right)=18$

Add 6 to both sides:

$-6-3\left(2x+4\right)+6=18+6$

$-3\left(2x+4\right)=24$

Divide both sides by -3:

$\frac{-3\left(2x+4\right)}{-3}=\frac{24}{-3}$

$2x+4=-8$

Subtract 4 from both sides:

$2x+4-4=-8-4$

$2x=-12$

Divide both sides by 2:

$\frac{2x}{2}=\frac{-12}{2}$

$x=-6$

Answer:

We can use excel regression data analysis tool to find the equation of the regression line that best fits the data.

The excel output is attached here.

Therefore, the equation of the linear regression is:

$\hat{y}=21.9028+1.5736x$

Where:

21.9028 is the intercept and 1.5736 is the slope.
