That is easy!! :)
y=3 and x=-7
When you find the factors of something like this, you have to just get the letter alone.
For example: y-3. You have to first write it as y-3=0, then you add 3 from BOTH sides of the = so that you can make the -3 go away and y will be alone. So, it will look like this: y-3+3=0+3. Then, you solve it for y (which just means that you want y by itself on one side of the = ). So, -3+3=0, which means they disappear from that side; since 0+3=3, that's what that side turns into, so what you end up with is y=3
Same thing goes for the x+7 equation:
x+7=0
x+7-7=0-7
x=-7
3x + 5 = 20
x = 5
Hope this helps
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: $6.66
Explanation:
3.70 multiplied by 0.80 = 2.96.
3.70 + 2.96 = $6.66
