The only things that will multiply to equal -5 is -5x1 or 5x-1. Of those two you can figure out which one adds to 4. Check each one: -5+1=-4 or 5+-1=4 (don’t forget adding a negative sign is the same subtracting). So the answer must be 5 and -1 * please comment on this if you need help understanding how to add and multiply negatives
Answer:
(x) =
Step-by-step explanation:
let y = f(x) then rearrange making x the subject , that is
y = 3x + 5 ( subtract 5 from both sides )
y - 5 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x with x = (x) , then
(x) =

hhhhhnn the answer is 3n+2.5.
Answer:
1 + 2sqrt(3)/3
Step-by-step explanation:
tan(30) = sqrt(3)/3
sin(90) = 1
tan(60) = sqrt(3)
cot(60) = 1/sqrt(3) = sqrt(3)/3
sqrt(3)/3 + 1 + sqrt(3)/3
1 + 2sqrt(3)/3
Answer:
2x - 2
Step-by-step explanation:
Move the numbers to be near their mates
4x - 2x + 8 - 10
Then solve as much as you can
4x - 2 = 2x, 8 - 10 = -2
<u>2x - 2</u>
