The slope of the line is 6, meaning that you can eliminate A,C. Since the point slope formula is y-y1=m(x-x1) you just need to see if the points are correct.

B. (3,9)
D. (1,-3)

While these do contain one point, substitute the coordinates to see which contain both.

B.

(1,-3): -3-9=6(1-3): -12=-12
(3,9): 9-9=6(9-3): 0= 6(6)

D.

(1,-3): -3+3=6(1-1): 0=6(0); 0=0
(3,9): 9+3=6(3-1): 12=6(2): 12=12

D is correct since the coordinate are on the line.

Answer:

x_1=5,\\x_2=2

Step-by-step explanation:

<u>Problem 1:</u>

The angles \angle 3 and \angle 7 are corresponding, and thus are equal to each other. We can then set up the following equation:

5x+2=27,\\5x=25,\\x=\fbox{$5$}.

<u>Problem 2:</u>

The angles \angle 6 and \angle 4 are supplementary, meaning they add up to 180^{\circ}. Therefore, we have the following equation:

18x+144=180,\\18x+36,\\x=\fbox{$2$}.

What is the solution to the inequality?
Trava [24]
ANSWER

A.

x <  - 2


EXPLANATION

The given inequality is

10x + 18 <  - 2


We add the additive inverse of 18, which is -18 to both sides of the equation to get,




10x + 18 +  - 18 <  - 2 +  - 18


Recall that,

-  +  =  -

This implies that,


10x + 18 - 18 <  - 2   - 18


We simplify to get,


10x + 0 <  -20


10x <  - 2 0


We now divide both sides by 10 to obtain,


\frac{10x}{10}   <  \frac{ - 20}{10}


We cancel out the common factors to get,

x <  - 2


The correct answer is A.
