Answer:
It should be "The unit rate is 2/3 every 1 hour" everything else is correct.
Step-by-step explanation:
Answer:
x=24
Step-by-step explanation:
4(2/3x+2)=3x
8/3x+8=3x
collect like terms
8=3x-8/3x
8=
cross multiplication
9x-8x=8 x 3
x=24
Answer:
Choice B) {-21, -7, 7, 21}
Step-by-step explanation:
The multiples of 7 are: 0, 7, 14, 21, 28, 35, ... both the positive and negative versions of each number. Erase the even numbers in that list to end up with 7, 21, 35, ...
Choice A fits the description, but there are items missing, namely -7 and 7. So this answer choice is crossed off the list
Choice B has both odd numbers and multiples of 7 listed. Every number is listed. This is why this is the answer.
Choice C has multiples of 7, but these are even numbers. We can cross it off the list.
Choice D is a similar story to choice C, though it has some odd numbers in this list.
To find the equation perpendicular to the graph of 4x - 2y = 1. First, rearrange the equation in slope intercept form and find the slope. Then take the reciprocal of the slope and add a negative to it.
4x - 2y = 1
-2y = 1 - 4x
-2y/-2 = 1/-2 -4x/-2
Y = -1/2 + 2x
Y = 2x - 1/2.
Assuming y intercept is the same (0,-1/2), we can find the new equation.
Y = -1/2x - 1/2.
I believe the above equation is the new line that is perpendicular to the original line.
Your answer is 400,000.
Hope this helps!
