Answer:
70 is the answer for this question
Answer:
<em>(J) </em>
Step-by-step explanation:
If the scale factor of dilation is greater than 1, the image is an enlargement.
If the scale factor of dilation is between 0 and 1, the image is a reduction.
The correct answer is A because a(in the equation) dictates slope and, if negative, think opposite

Answer:
- vertical change: 1 unit
- horizontal change: 2 units
- rate of change: 0.5
Step-by-step explanation:
The marks on the graph show the vertical change is 1 unit, and the horizontal change is 2 units.
The "rate of change" is the ratio of vertical change to horizontal change:
rate of change = slope = Δy/Δx = 1/2 = 0.5
Expressed as a decimal, the rate of change is 0.5.
So first (3 1/2) equals to 3+1/2 which is 7/2, same for(2 1/3), 2+1/3=7/3. It's asking for speed in laps per minute, so like how many labs did she swim per minute, which is labs over time——(7/2)/(7/3)=(7/2)*(3/7)=3/2. So she swam 3/2 labs per minute.
