Formula: y = mx + b
m being the slope
Slope given: -2, plug it in
Y = -2x + b
Now find y intercept (b)
Plug in the point (5,-11)
-11 = -2(5) + b
-11 = -10 + b, b = -1
Solution: y = -2x -1
Means Evan completes the 1/168 of the job each hour, and together they complete 1/56 each hour. 1/56 = 3/168, so Evan completes 1/168 of the job each hour and Emma completes the other 2/168 (so together they add up to be 3/168). So Emma completes 2/168 = 1/84 of the job per hour if she does it alone. So 84 hour is how long it takes.
Answer:
g(-4)= -52
Step-by-step explanation:
g(x) = 8x -20
Substitute -4 for x
g(-4) = 8(-4) -20
g(-4) = -52
Answer:
c)3
Step-by-step explanation:
Just Google the answer or better yet try to at least solve it
Log 100 equals 2. If you use a scientific calculator it equals 2.
