Answer:
The amount of money he is putting into the account
Step-by-step explanation:
By definition of absolute value we have two equalities:
2x + 1 = 10
2x + 1 = -10
For 2x + 1 = 10:
2x + 1 = 10
2x = 10-1
2x = 9
x = 9/2
For 2x + 1 = -10:
2x + 1 = -10
2x = -10-1
2x = -11
x = -11 / 2
Answer:
{-11/2, 9/2}
Answer:
68
Step-by-step explanation:
Since this is an isosceles triangle the bottom 2 angles are equal. So both bottom angles are 56 degrees. The three angles of a triangle add to 180 degrees.
56+ 56+ x = 180
Combine like terms
112 +x =180
Subtract 112 from each side
112-112+x = 180-112
x =68
X²-10x+15=0
x²-10x=0-15
x²-10x=-15
x(x-10)=-15
x=-15/(x-10)
