Answer:
m = 7
Step-by-step explanation:
Step 1:
- 6m + 8 = - 6 - 4m Equation
Step 2:
8 = - 6 + 2m Add 6m on both sides
Step 3:
14 = 2m Add 6 on both sides
Step 4:
m = 14 ÷ 2 Divide
Answer:
m = 7
Hope This Helps :)
Answer:
8+6=6m-4m( because when 6goes to first its+ be- and -6m goes right it be 6m it has own and rule).
then,
14=2m

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%

-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

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 slope and y-intercept of y = 3x – 1
Answer:
The slope is 3, and y-intercept is -1.
Step-by-step explanation:
All slope - intercept equations are written in the form y = mx + b. m represents the slope and b represents the y-intercept. Therefore, the slope is 3 and the y-intercept is -1.
the slope of the line is 3, and the y-intercept is -1
In the equation y = 3x - 1, the coefficient of x (the number multiplied by x) is 3. This coefficient represents the slope of the line.
Therefore, the slope of the line y = 3x - 1 is 3.
To find the y-intercept, we can observe that the equation is in the form y = mx + b, where b represents the y-intercept. In this case, the y-intercept is the constant term, which is -1.
Therefore, the y-intercept of the line y = 3x - 1 is -1.
In summary, the slope of the line is 3, and the y-intercept is -1. These values provide information about the steepness of the line and where it intersects the y-axis.

Answer:
100, because 180 - 50 - 90 = 40
The vertical angles theorem is applied, so now angle DCE is 40
And since CE = ED, its isosceles triangle, so base angles are equal, so 40 and 40.
180 - 80 = 100 = Angle E.
What is the equation for this great?
