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
Answer:
what's there to intercept its 1 line
Answer:
8c - 7r + 10p - 20e
Step-by-step explanation:
Subtract (20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)
(20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)
Open bracket
20c + 15r + 75p + 50e - 12c - 22r - 65p - 70e
Collect like terms
= 20c - 12c + 15r - 22r + 75p - 65p + 50e - 70e
= 8c - 7r + 10p - 20e
Answer:
DFG
Step-by-step explanation:
It is a right triangle, and so is DEF. Thus they are similar.
Step-by-step explanation:
2. Amount of soil provided.
In order to give different pH values of the soil, the amount of soil can directly affect this independent variable.
