Answer:

I believe you distribute 2 into x and 1 so you would get 2x + 2 - 8= x-1. then you would want to get all the number variables on one side of the equation and solve.

Write the equality for the graph

Veronika [31]

≥ the graph would be going to your right

≤ the graph would be going to your left

Both cases assume x is on the left side of the inequality.

If the circle is open < or > will be used.

If the circle is shaded in then use ≤ or ≥

If the circle is open, then x<2 would indicate that the ray is going left (which it is) and 2 is not included.

Answer: x < 2

estamos construyendo una carretera que enlace los puntos a = 12 ,21 y b =(17,23) otro punto se encuentra en c =(3,9) es posible

Nadusha1986 [10]

Answer:

is not possible

Step-by-step explanation:

<u><em>The question in English is</em></u>

we are building a road that links the points a = (12 ,21) and b =(17,23) another point is in c =(3,9) it is possible that a single road allows to join these three points?

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

step 1

Find the slope ab

we have

a = (12 ,21) and b =(17,23)

substitute

$m=\frac{23-21}{17-12}$

$m=\frac{2}{5}$

step 2

Find the slope ac

we have

a = (12 ,21) and c =(3,9)

substitute

$m=\frac{9-21}{3-12}$

$m=\frac{-12}{-9}$

simplify

$m=\frac{4}{3}$

step 3

Compare slopes ab and ac

The slopes are different

That means ----> is not possible that a single road allows to join these three points

Answer: 46 degrees

Explanation:

Angle PRS = 98 degrees

The two smaller pieces add up to this larger angle, so,

(anglePRQ) + (angleQRS) = angle PRS

(3x-8) + (2x+6) = 98

5x-2 = 98

5x = 98+2

5x = 100

x = 100/5

x = 20

Then we can find each angle

angle PRQ = 3x-8 = 3*20-8 = 52 degrees
angle QRS = 2x+6 = 2*20+6 = 46 degrees

Notice how 52+46 = 98 to confirm the answers.
