Answer:
x = 7/15
Step-by-step explanation:
you can check by replacing the x with the number I gave you
Answer:
the answer will be something like 18
*Hint: When you have two y's, they could equal each other in order to solve for the x value.
|x^2 -3x + 1| = - (x - 1)
x^2 -3x + 1 = -x + 1
x^2 - 2x + 1 = 1
x^2 - 2x = 0
x (x - 2)
x = 2 and x = 0
Once both of them are plugged in, only x = 2 works so that's the value for x. Now we just plug it in order to solve for y.
y = x - 1
y = 2 - 1
y = 1
(2, 1)
The answer would be C.
(x + 5)^2 + (x/2 + 6)^2 = (30)^2
Take it from here.
Answer:
Daniela spent 1/20 of an hour longer on her English homework than her Math homework.
Step-by-step explanation:
I think what your asking is how much longer Daniela took on her English homework then her math homework. If that's what your asking, you need to subtract 3/4 from 4/5.
First, the denominators need to be the same (meaning we have to multiply them):
4/5 * 4 = 16/20
3/4 * 5 = 15/20
Finally, we subtract the two fractions:
16/20 - 15/20 = 1/20
