Answer:
x =9/4
Step-by-step explanation:
log3(4x) = 2
Raise each side to the base of 3
3^ log3(4x) = 3^2
We know that 3log3 is 1
4x = 9
Divide each side by 4
4x/4 = 9/4
x = 9/4
Answer:
a
Step-by-step explanation:
A is the answer, since when you graph it, you are able to visualize y crossing -2 and x crossing 3.
Answer:
5(2x+5)
Step-by-step explanation:
This is the answer because the highest multiple is 5 for both of them.
so since it is 5 divide both numbers by 5 put 5 outside the parenthisis and
then divide the numbers inside
this will give you - 5(2x+5)
Hope it helps :)
Answer:
r = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 
m = 
with (x₁, y₁ ) = (- 9, - 3) and (x₂, y₂ ) = (- 2, r)
m =
, that is
=
( cross- multiply )
7(r + 3) = 7 ( divide both sides by 7 )
r + 3 = 1 ( subtract 3 from both sides )
r = - 2
