What are you trying to find?
Answer:
D
Step-by-step explanation:
Plug in and see.
Check A: Lets plug in (0,3) into y<2/3 x+2.
3<2/3 (0)+2
3<2 is not true so not A
Check C: Lets plug in (3,5) into y<2/3 x+2.
5<2/3 (3)+2
5<2+2
5<4 is not true so not C
Check B: Lets plug in (-3,1) into y<2/3 x+2.
1<2/3 (-3)+2
1<0 is not true so not B
Check D: Lets plug in (1,2) into y<2/3 x+2.
2<2/3 (1)+2
2<2/3+2 is true so D
Answer: <em>In the upper triangle x = 33° and in the lower triangle x = 128°</em>
Step-by-step explanation:
<em><u>Upper triangle:
</u></em>
<em>x = (180° - 114°) ÷ 2 = 33°</em>
<em><u>Lower triangle:</u></em>
<em>x = 180° - 26° × 2 = 128°</em>
Answer:
34
Step-by-step explanation:
We start by working out the slope. The slope is change in y over change in x, so (66-58)/(-56)-(-42) is the slope here. 66-58 is 8, and -56-(-42) is -14. -8/14=-4/7. The equation of a line in slope-intercept form is y=mx+b where b is the y intercept and m is the slope. Since the slope is -4/7, then y=-4/7x+b. We then insert any x and y pair into this equation and solve for b, the y intercept to get it. (We can do ANY pair) So, 50=(-4/7)(-28)+b.
: 50=16+b
: 50-16=b
: 34=b
So, in conclusion, the y intercept is 34. Hope this helps!
Answer: 63 degrees.
Step-by-step explanation:
7x + 4 +5x+3+2x+5=180 degrees
14x+12=180 -12 Degrees
14x / 14 = . 168 /14
x=12
5(12) +3
63
