Answer:
1. x = 47
2. x = 156
3. x = 62
4. x = 58
Step-by-step explanation:
1. 180 - 133 = 47
2. 180 - 24 = 156
3. 28 + 90 = 118. 180 - 118 = 62
4. 32 + 90 = 122. 180 - 122 = 58
The slope of the line passing through the points (-4 , 0) and (7 , 0) is 0 ⇒ 3rd answer
Step-by-step explanation:
The formula of the slope of a line is 
where
and
are two points on the line
To find the slope
- Let one of the two points to be

- Let the other point

- Substitute them in the formula of the slope
- Calculate the value of m
∵ The line passes through points (-4 , 0) and (7 , 0)
∴
= -4 and
= 7
∴
= 0 and
= 0
- Substitute these values in the formula above
∴ 
∴ m = 0
The slope of the line passing through the points (-4 , 0) and (7 , 0) is 0

Answer:
5/3
Step-by-step explanation:
Plug the 3 into the equation.
3 = (-3/5)x+4
Solve.
-1 = (-3/5)x
5/3 = x
x = 5/3
