Answer: The answer is given below.
Step-by-step explanation: We are given an equality involving logarithm and we are to show the implication of L.H.S. to R.H.S.
We will be using the following two properties of logarithm:

The proof is as follows:

Hence proved.
To do this subtract 2 from each side of the equation to get y = -5, so the value of y in this is -5. Hope this helps!
By angle addition postulate,
m(∠ABD) + m(∠DBC) = m(∠ABC)
Now substitute the values of each angle,
(5x + 5)° + (3x + 12)° = 153°
Combine like terms of the expression,
(5x + 3x) + (5 + 12) = 153
8x + 17 = 153
8x = 153 - 17
x = 
x = 17
Substitute the value of 'x' to get the measure of each angle,
m(∠ABD) = (5x + 5)
= 5(17) + 5
= 90°
m(∠DBC) = (3x + 12)
= 3(17) + 12
= 63°

Answer:
C and D
Step-by-step explanation:
Use Pythagorean theorem to test
a^2 + b^2 = c^2 ? a and b are the shorter two sides c = longest side
Doing this for each data set shows C and D ARE rt triangles
Answer:
B is -6.
Step-by-step explanation:
y=mx+b
6 is negative and is in the place of the y intercept (b)
