-x = 4 -3x + 6
First, let's get x on one side.
Add 3x to both sides.
-x + 3x = 2x
-3x + 3x = 0
We now have:
2x = 4 + 6
Combine like-terms (add 4 to 6)
4 + 6 + 10
2x = 10
Divide both sides by 2 to solve for x.
2x / 2 = x
10 / 2 = 5
We're now left with:
x = 5
I hope this helps!
(4b+3) (2b−5)
(4b+3) (2b+−5)
(4b) (2b) + (4b) (−5) +(3) (2b) +(3) (−5)
8b²−20b+6b−15.
= 8b²−14b−15.
The vertical distance between Dean and Jeff is 13 ft below the surface
Explanation:
Jeff dove 39 ft below the surface and then ascends 18 ft
-39 - 18 = 21
Jeff is 21 ft below the surface
------------------
Dean is 34 ft below the surface
-34 - (-21) = -13 ft
-----------------
So, Dean and Jeff are 13 feet away from each other (vertical distance).
The formula for point slope form is (y-y1) = m(x - x1)
In this formula m will always be the slope. So, you can substitute 3 in for m
(y-y1) = 3(x-x1)
y1 is the y-coordinate and x1 is the x-coordinate. So, you can substitute them in and you will be done.
(y - 1) = 3(x - (-2))
But since it is minus a negative it changes to a positive so it would be:
(y -1) = 3(x + 2)
Hope this helps!
