Answer:
Step-by-step explanation:
Angle EFB = 180 - 147 = 33 (Angles on a straight line add up to 180 degrees)
Angle FEB = 180 - 4x (Angles on a straight line add up to 180 degrees)
Since the angles in a triangle add up to 180 degrees ,
Remove brackets:
Add/Subtract:
Subtract 213 from both sides:
Divide both sides by -3:

Question # 28
We can use any two points to find the equation of the total cost(y) in terms of number of square feet(x).
I will be using first two points (1800, 630) and (2300, 805)
First we need to find the slope of the line.
Using the slope and a point (1800, 630) we can write the equation as:
y - 630 = 0.35 (x - 1800)
y = 0.35x - 630 + 630
y = 0.35x
So, option G gives the correct equation of the function.
Question # 29
Given function is:
y = 3.54x - 54.68
Increasing the y-intercept by 33.14 will result in following equation:
y = 3.54x - 54.68 + 33.14
y = 3.54x - 21.54
Notice that the slope of the lines are still the same. This suggest the lines are parallel. Addition or subtraction of a number to y-intercept only shifts the graph vertically. So in this case the graph will be shifted up by 33.14 units and will be parallel to the original line. Since graph is shifted up, its y-intercept will also be shifted up i.e. y-intercept will increase.
x-intercept is the point where y is zero. So substituting y=0 in both equations and finding the value of x will result in x-intercepts. The x-intercept decreases on shifting up the y-intercept in this case.
So, the only correct option is option A

Just subtract 20.35 from 100.8
if your bag weighs 100.8 kg and you scoop out 20.35 kg then weigh your bag it will be 80.45 bc u took out 20.35 kg of the cement to use. hope that explains it
