The value is -6
(-1,-6)
all you have to do it plug in -1 for x
f(-1)= -2(-1+4
f(-1)=-2(3)
f(-1)=-6
The midpoint of EF is M. The length of EM is 5
Given :
The endpoints of EF are E(2, 3) and F(8, 11).
M is the midpoint of EF
Lets find out the midpoint M using midpoint formula

Substitute the values inside the formula

Midpoint M is (4,7)
Now to find out length of EM, we use distance formula

So, length of EM= 5

In triangle ABC, two angles angle A and C are already given
Angle A =33.7
Angle C = 26.4
We know that the sum of angles in a triangle is 180 degree
Angle A + B + C = 180
33.7 + angle B + 26.4 = 180
60.1 + angle B = 180
Angle B = 119.9 degrees
Now we use sin angle formula to find b. Given a=24



b = 37.4979
Round answer to two decimal places
b = 37.50
Answer:
0
Step-by-step explanation:
Write out the 2 equations:
2x + y = -3
-2y = 6+4x
-You then pick a variable that you want to solve for. I chose to solve for y because it would be a bit easier.
-2y = 6 + 4x
-Divide both sides by -2 to isolate the variable
(-2y) / -2 = (6 + 4x) / -2
-it comes out to y = -3 -2x
-Now that you have the y you can plug in the value into the second equation.
2x + y = -3 ---> 2x + (-3 -2x) = -3
This can be simplified to:
2x - 3 - 2x = -3
The 2x's cancel out because there is a +2x and a -2x. You are left with a
-3 = -3. If you add 3 to both sides of the equation you end up with 0 = 0, which can be simplified to just 0.
