Hi There!
Answer:
C) about $8
Step-by-step explanation:
If you look at the graph you notice that line dosen't reach 100 so you just to imagine that line keeps going. You also notice that the line reaches about 8.
Hope This Helps :)

3x + y = 9 is equivalent to -15x - 5y = -45 by multiplying both sides by -5
<u>
</u> -15x - 5y = -45<u>
</u><u>+ </u><u>4x + 5y = 23</u>
-11x + 0y = -22
<u>
</u>-11x = -22
<em>x = 2</em>
3(2) + y = 9
6 + y = 9
<em>y = 3
</em>4)<em>
</em>2x + y = 17 is equivalent to -6x - 3y = -51 by multiplying both sides by -3
<em>
</em> 4x + 3y = 37
<u>+ (-6x - 3y = -51)
</u> -2x + 0y = -14
-2x = -14
<em>x = 7</em>
4(7) + 3y = 37
28 + 3y = 37
3y = 9
<em>y = 3</em><u>
</u>6)
x + 2y = 18 is equivalent to -10x - 20y = -180 by multiplying both sides by -10
10x - 3y = 19
<u>+ (-10x - 20y = -180)</u>
0x - 23y = -161
-23y = -161
<em>y = 7</em>
10x - 3(7) = 19
10x - 21 = 19
10x = 40
<em>x = 4
</em>
I hope this helped ^_^
The two triangles BQA and DQC are similar triangles. The ratio of corresponding sides of similar triangle is the same.
So, we can write:
BQ : BA = DQ : DC
15 : 32 = DQ : 19.2
⇒
32 * DQ = 19.2 * 15
DQ = 9
We are to find the length of BD.
BD = BQ + QD = 15 + 9 = 24
So the answer to this question is 24
Answer:
X = - 5/3 or X = -1.6
Step-by-step explanation:
Move variable to the left hand side and change its sign
Collect like terms
Divide both sides of the equation by -3
You just find the coordinate point. then, use your slope 2/3 (up 2, right 3) :)
EX: if your slope was negative, you’d do the same thing, but opposite -2/-3 (down 2, left 3)
hopefully this helps, good luck with math!! <3
(ps sorry if the drawing bothers you, but I wanted to show you as best as I could on how to solve your question :) )
