I think you're having trouble because the equation you wrote for 8a has a slight typo.
The question says that the length is 9 less than twice the width. Your equation states the length is 9 times the width minus 2. So the length actually equals 2w – 9, meaning that w(2w – 9) = 180
Hope this helps! If you're still having trouble, let me know :)
Answer:
rate of change=slope= y2-y1/x2-x1
Step-by-step explanation:
x: -2|-1|0|1
y : 5|4|3|2
so choose 2 ordered pairs. in this case, we will choose (-2,5) and (-1,4)
now we plug them in: 
4-5=-1
-1-(-2)=1
so -1/1 is equal to -1, meaning it's answer option b.
Hello from MrBillDoesMath!
Answer:
5 x^3 + 15 x^2 + 15 x + 5 , none of the provided choices
Discussion:
f(x) = 5 x^3
g(x) = x+ 1
=>
(f•g)(x) =
f(g(x)) =
f(x+1) =
5 * (x+1)^3 =
5 x^3 + 15 x^2 + 15 x + 5
which is none of the provided answers.
Thank you,
MrB
Answer:
The answer could be easier if you make a ratio and actual graph
Step-by-step explanation:
Answer:
3/10
Step-by-step explanation:
An hour is 60 mins
so the fraction would be 18/60
Then you can divide both numbers by 6 to 3/10
