Multiply. Distribute 3x to all terms in the parenthesis: x and -8
3x(x) = 3x²
3x(-8) = -24x
3x² - 24x is your answer
hope this helps
Answer:
y= (6/5)x-3
if you want the slope it's 6/5 and the y intercept is -3
Step-by-step explanation:
sI'm not too sure what the question so i'll just assume that you want to write this in slope intercept form
or y=mx+b
to do this all we need to do is have y be positive and by itself
to do this you can just divide both sides by -5
which gives us
y= (6/5)x-3
Answer:
its D
Step-by-step explanation:
X-doubling periods
Y-height of bamboo
Y=ab^x
1) make a table of values
X Y
1 5
2 10
3 20
2) write equations and substitute
5=ab^1 —> a=5/b^1 —> a=5/b
10=ab^2
Substitute into second equation
10=(5/b)*b^2
10=5b^2/b
10=5b
b=2
Substitute back in
b=2
10=a*2^2
10=4a
a=5/2
End equation:
Y=5/2*2^x
