For a distance vs time graph. X axis is time and Y axis is distance. at t=6s, dist=5m at t=8s, dist=6m at t=10s, dist=7m at t=12s, dist=8m I don't see any of those as choices.
Problem 1 A is not the answer. f(4)- f(1) =11 - (-1) = +12 -------------- Problem 3. C looks correct
Problem 2. The answer is not B, (x=0).
Problem 1. The answer is NOT D. The average rate of change is: for x=1, f(1)=-3 for x=4, f(4)=-3 Average rate of change is 0, not a negative number. One of the answers does give a negative average rate of change.
Yes, that's what I got, also.
Let B = the "break even" number of books. Production costs=$76,322 + B * $10 Total Sales = B * $25.50 Setting these equal... Total sales = Production costs or... $76,322 + B * $10 = B * $25.50 Solve for B
MATH 7th GRADE
1, 2, 3, 4, and 6 look OK I don't understand 5, 7 is wrong.
MAT 7th GRADE
number 4 should be +5 6 is wrong.
slope = rise/run. For a slop of 0.4 0.4 = rise/130 Solve for rise. It looks like you have accidentally moved the decimal in your line: .040=rise
