Answer:
Choice B: Only (-2, 9)
Step-by-step explanation:
Of the two choices, only the point (-2, 9) satisfies the equation:
... y = -2x +5
... 9 = -2(-2) +5 = 4 +5 = 9
Answer:
x=50
Step-by-step explanation:
since all triangles angles add up to 180 and x and the other corner look equal, than minus 80 from 180 and then divide by two (because of the 2 corners.) x=50 degrees
Answer: 
Step-by-step explanation:
To solve this exercise it is important to remembet the definition Definition of a Logarithm:
If
and, 
, then
is equivalent to
(which is the exponential form).
Knowing this definition and having the following logarithmic equation:

You can identify that:

Therefore, susbtituting values into
, you can rewrite this equation as an exponential equation. Then:

Answer:
x=7/5
Step-by-step explanation:
So u times it first so -15p-15-63+9p
so it would short it down because of cobine like terms -6p-78
