Answer: 3
Explanation: logarithm base 8 of 512 is 3
Answer: y = 1/2 or y = -1/2
Step-by-step explanation:
First move the 1 to the side with the 0
-4y^2 = -1 // -1 because when you move a number to the other side of the equation you have to multiply -1
Then divide by -4 on each side
y^2 = 1/4
square root each side
|y| = 1/2 // sq rt y^2 becomes an absolute value because when you square root a square it automatically becomes an absolute value
so the answer would be y = 1/2 or -1/2
to check just put it into the equation as y. Both work.
Answer:
Step-by-step explanation:
x - 9 = 17
x = 26
the answer is D
Answer: m1 m2 and m5 all equal to 135 as well
While m3 m6 and m4 are 45
Why: since they are on a line the two angles together should equal 180. So 180- 135= 45

Answer: 1</h3>
Explanation:
The jump from 2 to 2&1/2 is an increase of 1/2
2 + 1/2 = 2 & 1/2
The jump from 2 & 1/2 to 1 & 1/2 is a decrease of 1
(2 & 1/2) - 1 = (2 - 1) & 1/2 = 1 & 1/2
The jump from 1 & 1/2 to 2 is an increase of 1/2
(1 & 1/2) + 1/2 = 1 + (1/2 + 1/2) = 1 + 1 = 2
The pattern seems to be "add 1/2, subtract 1". Assuming this is the case, we would then subtract 1 from the last term we got (2) to get 2-1 = 1
