I thought it would be c but try b or a
Hi!
When multiplying by ten, the decimal moves one space to the right.
^the answer
I also included an image showing the decimal place moved to the right.
Hope this helps! :)
Solving for y, we add 5x to both sides to get 2y=14+5x, and divide by 2 to get
y=2.5x+7. The slope is the coefficient of x, which is 2.5
Answer: False!
This equation is in slope - intercept form, where y = mx + b. B is the y - intercept and m is the slope. They got the location of the y - intercept right, but they forgot to add the negative. It's actually -8.
Hope this helps!

Answer:
A. 120%
B. 150%
Step-by-step explanation:
a. Let 'a' represent the percentage of interest.
600 = a% × 500
600/500 = a/100 . . . . . . . % means /100
100(6/5) = a = 120
600 is <u> 120 </u>% of 500
__
b. Let 'b' represent the percentage of interest. The given statement means ...
100 = 40 + b% × 40
100 = 40(1 +b/100) . . . . . factor out 40, use /100 for %
2.50 = 1 +b/100 . . . . . . . divide by 40
1.50 = b/100 . . . . . . . . . . subtract 1
150 = b . . . . . . . . . . . . . . multiply by 100
100 is <u> 150 </u>% more than 40
