<u>Simplify:</u>
Answer:
A. (5x - 2) - (2x +1)
B. x -1
C. 68
Step-by-step explanation:
Heather = 5 times Donna -2 H = 5D - 2
Gina = 2 times Donna + 1 G = 2D + 1
Plug in D for X and you get
H = 5x -2
G = 2x + 1
If Heather's expression is 5x -2 and Gina's expression is 2x + 1 then to show how many more Heather has than Gina. You have to subtract Gina from Heather.
(5x - 2) - (2x +1)
Now to simplify it, you just combine all the like terms.
5x - 2 - 2x -1 = 3x - 3 and then you can simply this further by dividing all terms by 3. x - 1
To solve how many Heather has if Donna has 14. You substitute 14 for x in Heather's equation. 5 (14) -2 = 70 - 2 = 68
Answer:
D
Step-by-step explanation:
Swap x for y and y for x. Then solve the equation for y.
We are given equation: y=ln(x) .
And translation is 5 units down.
We know the rule of transformation f(x) = y + k, if k is greater than 0 it would move up or if k is less than 0, it would move down.
For the given translation 5 unit down, 5 should be less than 0.
Number less than 0 are negative numbers.
So, we need to add -5 in the given function to ln(x).
So, we would get the final equation for five units down as
y =ln(x) - 5.
