Answer:
4 and 8
Step-by-step explanation:
Let 'a' represent one of the numbers. Then the other is 12-a, and their difference is ...
a - (12-a) = -4
2a = 8 . . . . add 12
a = 4 . . . . . divide by 2
12-a = 8 . . . . find the other number
The two numbers are 4 and 8.
Answer:3/8y+(6x+4)
Step-by-step explanation:
I’m 99% sure to is is right
first invert fraction of the slope from 4/1 to 1/4 and switch sign. then figure out the y-intercept
the algebraic approach would work like this:
-4x + 10 = 1/4x + b
plug in what you got, here: the intersection information
-4*(4) + 10 = 1/4*(4) + b
-16 + 10 = 1 + b
-6 = 1 + b
-7 = b
Answer:
x = 3
Step-by-step explanation:
7(x + 4) - 7 = 48 - 2x ← distribute parenthesis and simplify left side
7x + 28 - 7 = 48 - 2x
7x + 21 = 48 - 2x ( add 2x to both sides )
9x + 21 = 48 ( subtract 21 from both sides )
9x = 27 ( divide both sides by 9 )
x = 3
