864=800+60+4 800 in the hundreds place 60 in the tens place and 4 in the ones place
Answer:
1. y = 1/4 and y = 1/4x+2
2. y - 1 = -x (x + 7) and y = -x and x + y = 3
-------
4. y = 3 and x = 6
5. y = 1/2x + 2 and y + 1 = -2x
6. Slope of <u>AB</u> = 2/3
Slope of BC = -3/2
AB is perpendicular to BC because 2/3(-2/3) = -1
ABC is a right triangle because it contains a right angle
Answer:
b
Step-by-step explanation:
b
Answer:
x=-4
Step-by-step explanation:
These two angles have to equal 180 because they are opposite of each other. Therefore, the equation will be 129+x+x+59=180. You add all common terms. 2x+188=180. You want to isolate x so you have to subtract both sides by 188. Therefore, the equation will be 2x=-8. Divide both sides by 2 to isolate x. x=-8/2. This is equal to x=-4.
