Answer:15b^2-5b^3+24b-16
Step-by-step explanation:
(4-b)(5b^2+5b-4)
Open the brackets
20b^2+20b-16-5b^3-5b^2+4b
Collect like terms
20b^2-5b^2-5b^3+20b+4b-16
15b^2-5b^3+24b-16
Answer:
Step-by-step explanation:
y=9/4 x-2
Where because I do not see it
Answer:
y = 1/5 x + 8
Step-by-step explanation:
slope of line j: m = -(1/-5) = 1/5
j pass (5,9): (y-9)/(x-5) = 1/5
y-9 = 1/5(x-5) = 1/5 x - 1
y = 1/5 x + 8
Here I did all I can do rn
