Answer: 10 or -10
Step-by-step explanation: 3x + 12 = -18
-12 both sides then you get 3x = -30 divide by 3 which equals x = 10 or -10
Since U is being subtracted by 8.1, we can assume that if we added 8.1 to both sides, it should equal U
U - 8.1 = 6.35 To make it equal to U, we have to add 8.1 to both sides
The answer is,
U = 14.45
Answer:
Step-by-step explanation:
For this question they are asking you to find y when x is {2, 4, and 6}
That means you need to plug 2,4, and 6 into the equation and solve.
For example:
f(x) = 5x - 4
f(2) = 5(2) - 4
f(2) = 10 - 4
f(2) = 6
f(x) = 5x - 4
f(4) = 5(4) -4
f(4) = 20 - 4
f(4) = 16
f(x) = 5x - 4
f(6) = 5(6) - 4
f(6) = 30 - 4
f(6) = 26
