Answer:
4^-3= 1/64
Step-by-step explanation:
Simplify the power using PEMDAS, so that will be 2-(3*4)+7, which is -3.
Then, since a number with a negative power has to be a fraction, it will be 1/64.

Simplify the expression below:
5m - 17 -5 + 2m
Answer:
-22 + 7m
Step-by-step explanation:
5m - 17 -5 + 2m (combine like terms)
- 17 - 5 = -22
5m + 2m = 7m
-22 + 7m
After simplification the given expression is 7m - 22.
Given expression is:
5m - 17 -5 + 2m
Add (- 17 -5) = -22
Add (5m + 2m) = 7m
5m -22 + 2m
7m - 22.
Therefore, the final expression is 7m - 22.

−4/11 ÷ 2/7=
Answer:
-14/11
Step-by-step explanation:
when dividing a fraction, you flip the second fraction and turn the division sign into multiplication
so now you have -4/11 x 7/2
4 is divisible by 2 so you have: -2/11 x 7/1
now multiply -2 with 7 and 11 with 1: -14/11

Line KR bisects JKM. If mJKR = 81°, what is the mJKM?
Answer:
[tex]m\angle JKM = 162^\circ[/tex]
Step-by-step explanation:
Angle Bisector
An angle bisector is a ray that divides an angle into two congruent angles, each having a measure exactly half of the original angle.
We are given ray KR bisects angle JKM.
This means angle JKM is divided into two congruent angles JKR and RKM. We know:
[tex]m\angle JKR = 81^\circ[/tex]
Thus, the measure of angle JKM is twice the measure of JKR. Therefore:
[tex]m\angle JKM = 2*81^\circ= 162^\circ[/tex]
[tex]\mathbf{m\angle JKM = 162^\circ}[/tex]

What is the value of -2xy if x = -1 and y = 6?
A. 12
B.-12
C. 26
D. 8
Answer: A
Step-by-step explanation:
If we are given the values of x and y, we just have to plug them into the expression. So -2xy means -2(-1)(6) which is 12. 12 corresponds to A so A is the correct answer.
Answer:
A , we find it like this :
-2(-1)(6)=12
-2t^2+4t+30 in vertex form
Answer:
- 2(t - 1)² + 32
Step-by-step explanation:
Given
- 2t² + 4t + 30
Use the method of completing the square to express in vertex form.
The coefficient of the t² term must be 1, so factor out - 2 from the first 2 terms.
= - 2(t² - 2t) + 30
To complete the square
add/subtract ( half the coefficient of the t- term)² to t² - 2t
= - 2(t² + 2(- 1)t + 1 - 1) + 30
= - 2(t - 1)² + 2 + 30
= - 2(t - 1)² + 32
There are 70 students in a school band . 40% of them are sixth graders , 20% of them are seventh graders , and the rest are eighth graders . what percentage of the band members are eighth graders?
Answer:
40% of the band members are eighth graders.
Step-by-step explanation:
There can only be a total of 100%. The problem already gives us the percentages of sixth graders and seventh graders, and it tells us that there are only eighth graders left. Subtract the sum of 40 and 20 from 100 to get your answer.
100% - (40% + 20%) = 40%
