In this equation x = 49.
In order to find this, follow the order of operation of solving equations.
1/7x - 5 = 2 -----> Add 5 to both sides
1/7x = 7 ----> Multiply both sides by 7
x = 49
The sum of opposite angles are equal, so two of the angles are 45°. The sum of all angles about the intersection of two lines is 360°. So the remaining two angles are found by:
α=(360-2*45)/2
α=135° thus all four angles are:
45°,135°,45°,135°
Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept → (0, b)
The formula of a slope:
We have two points (8, -4) and (0, 2) → b = 2.
Calculate the slope:
Therefore the equation of a line t in the slope-intercept form is:
