Answer:
9/3=3
Step-by-step explanation:
the formula is y2(7) minus y1(-2)
divided by x2(-4) minus x1(-7)
Answer:

Step-by-step explanation:
In relation to the given angle, we are given the triangle's opposite side and hypotenuse. Therefore, we use the sine function to set up a proportion and solve for the opposite side:





Therefore, the length of the opposite side is about 7.8 units
The answer is 5-3/2x. Hope this helps :)
Answer:
Slope of the line is
.
Step-by-step explanation:
Given points are:
(10, 3) and (7, 11)
Here,
x1 = 10 and y1 = 3
x2 = 7 and y2 = 11
Slope of a line is given by

Therefore,
Slope of the line is
.
1/2DF = EF
1/2(2y) = 8y - 3
y = 8y - 3
- Subtract 8y from both sides.
-7y = -3
y = 3/7
- Plug 3/7 for y into DF and EF.
DF: 2(3/7) = 6/7
EF: 8(3/7) - 3 = 24/7 - 3 = 3/7
EF = DE because they are bisected, so DE = 3/7
