Answer:
The correct answer is option D. Dilation by a scale factor of 2 followed by reflection about the x-axis
Answer:
x≤ -7 or x≥ -4
Step-by-step explanation:
There is a closed circle at -7 and the line goes to the left
x≤ -7
There is a closed circle at -4 and the line goes to the right
x≥ -4
Since they both can't be true at the same time it is an or
x≤ -7 or x≥ -4
Answer:
The student took 2.5 minutes to paint 1 square foot.
Step-by-step explanation:
In order to know how long the student took to paint each square foot we first need to know the total area of the bulletin board. Since it is a rectangle we can compute it's area by multiplying the width and the height. That is:
area = 2*3 = 6 square foot
Since the student took 15 minutes to paint the whole board the pace at which he was working can be calculated by dividing the total area of the board by the time he took to paint all of it. So we have:
pace = 6/15 = 0.4 foot/min
To find how long it took him to paint 1 square foot we can divide it by the pace he was painting. We have:
time = 1/0.4 = 2.5 minutes
The student took 2.5 minutes to paint 1 square foot.
48/14 so you just simplify that for gallons/minutes. something that goes into both of those numbers is 2 so you would have 24/7 when you divide by 2. that’s your answer.
24/7
