11.2x+x+(x+8)=180
Combine like terms
3x+(x+8)=180
4x+8=180
180-8=172
4x=172
x=43

12.(x-3)+x+(x+8)+(x-5)=360
Combine like terms
4x-3+8-5=360
-3+8=5
5-5=0
4x=360
x=90

Answer:

This is not the answer this is the trick to find it

Step-by-step explanation:

The points after reflection will follow points equal but different direction, to the path followed before the reflection. So, if the line would cover 3.5 on the x and 5 on the y; it will reflect symmetrically giving you the formula to get your answer.

Write a linear inequality in two variables that has (-1, 3) as a solution but does not have (4,0) as a solution.

Stels [109]

Answer: y ≤ -x + 2

<u>Step-by-step explanation:</u>

There are an infinite number of possible solutions.

Plot the two points, draw any line between them such that the two points are NOT connected, then choose the inequality symbol that shades (-1, 3).

Here is one solution that satisfies the requirements. y ≤ -x + 2

Here is another: y < -x + 3

And another: y > x + 3

And one more: y ≥ x + 4

The slope of the lines that passes through the points (-10,0) and (-13,3)

goldenfox [79]

Answer:

-1

Step-by-step explanation:

The formula to find the slope of a line is:

$\frac{y_{2}- y_{1} }{x_{2} -x_{1} }$

where (x1, y1) and (x2, y2) are points on the line. We can substitute the points (-10, 0) and (-13, 3) into the formula and simplify:

$\frac{3-0}{-13-(-10)} =\frac{3}{-13+10} =\frac{3}{-3} =-1$

This means the slope of the line is -1.
