A. Multiplication is the ONLY function that reverses what division did. If you did 56/-14 = n, then n x -14 should equal 56.
John's. Find the first common multiple of both denominators, in this case it's going to be ten, then the number you had to multiply to change these numbers to the common multiply you do to the numerators. so it works out like so:
Deena has a bottle of 4/10
John has a bottle of 25/10 or 2 1/2 (simplified)
The answer is m=4/5 so the slope of the line is 4/5
Answer:
y = -2x + 7.
Step-by-step explanation:
The slope is (5-7)/1-0 = -2 ,
Checking with other values: slope = (- 3 - 7)/ (5-0) = -10/6 = -2.
So the function is -2x + c where c is some constant.
Plugging in the point (0, 7):
7 = -2(0) + c
c = 7.
So the answer is y = -2x + 7.
