Okie, so there are 2 ways to approach this problem. One way is to solve the problem via substitution. The other method which I'll use in this case is plug it in. So, let's go one by one.
2(0) - 2(-6) = 12 yup
2(4) - 2(-2) = 12 yup
2(-6) - 2(0) = 12 nope
2(-2) - 2(4) = 12 nope
So we canceled it down to 2 left. Now, plug the two possible answers into the second equation.
(-6) ^ 2 + (0) ^ 2 = 36 yup
(-2) ^ 2 + (4) ^ 2 = 36 nope
The answer that fits both equation is therefore the first one (-6,0)
I hope this helps :-)
Answer:
FE = 12
Step-by-step explanation:
10/15 = 8/FE
10FE = 120
divide both sides of the equation by 10:
FE = 12
He complete 468 passes and this represents 71.2% of his attempted passes. Set this up as a ratio. 468 71.2---- = ------ x 100 cross multiply and solve46800 = 71.2xx = 657.3He attempted 657 passes.
Answer:
x=57
Step-by-step explanation:
63+60= 123
A triangle is 180 degrees
180-123= 57
x=57
Thing is, you didn't give us the choices!
