Given
and
(say).
Then,

From the above 3 equations,

From the equations, we get

Since
, the negative value is rejected.

Answer:
y=3x + 1
Step-by-step explanation:
slope is same
insert coordinates into x and y values
determine y-intercept
12. 4(s+5)
4s+20
15. 2(3r-12)
6r-24
18. -3(16-3d)
9d-48
There all log base 3, the base won't matter as long as they're all the same.
log(x^2/y)=2log(x)-log(y)=2(4.5)-3=6
Answer: c. 6
Answer:
= 2(2x + 5)
Step-by-step explanation:
Given that:
= (7x + 5) - (3x - 5)
By simplifying
"-" sign before bracket will alter the inner signs
= 7x + 5 - 3x + 5
Adding like terms
= 4x + 10
By taking 2 common we get:
= 2(2x + 5)
