You cannot add -10y+9x or 10y+5x because of the rule “combine like terms”...
Answer:
X = 8
Step-by-step explanation:
Since the shape is a parallelogram the opposite sides are equal
The equation is:
Solve:
- 6 + 10 = 2x -10 + 10
- 16 = 2x
- 2x = 16
- Divide by 2 on both sides
- <u>x = 8</u>
Check:
- 2(8) - 10 = 6
- 16 - 10 = 6
- 6 = 6
- CD = BE
- 6 = 6
Answer: 13.96 in²
<u>Step-by-step explanation:</u>
d = 2r
16 = 2r
8 = r

180(θ) = 25(π)
θ =
θ = 
A =
r² θ
= 
= 
= 13.96

Answer: 22.440 cm²
<u>Step-by-step explanation:</u>
A =
r²θ
=
(10)²
= 
= 22.440

Answer: 270°, 630°, -450°, -810°
<u>Step-by-step explanation:</u>
positive: -90 + 360 = 270
270 + 360 = 630
negative: -90 - 360 = -450
-450 - 360 = -810

If you subtract another 2π, you will end up with a negative value. The question asks for the smallest positive value.
Y=-5x+1
Slope intercept form is y=mx+b
m is slope and b is the y-intercept
It can be used on this one 10x=3
