Answer:
In some schools yes but it depends is it a required class? if so then you'd have to retake it.
y = 20x
The graph passes through the origin , hence is of form
y = mx ( m is the slope )
to calculate m use the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁) = (2, 40) and (x₂, y₂) = (4, 80) ← 2 points on the graph
m = 
= 
= 20
y = 20x
Answer:
#3
Step-by-step explanation:
If it is parallel to the x axis it has 0 slope, and that means its y=y value. The y value here is 13 so,
It has a slope of zero and an equation of y=13
13.5 tablespoons of concentrate need to be mixed with 9 gallons of water.
Given that the directions for a weed spray concentrate state that 3 tablespoons of the concentrate should be mixed with 2 gallons of water, to determine how many tablespoons of concentrate need to be mixed with 9 gallons of water, the following cross multiplication calculation must be performed :
- 2 = 3
- 9 = X
- 9 x 3/2 = X
- 27/2 = X
- 13.5 = X
Thus, 13.5 tablespoons of concentrate need to be mixed with 9 gallons of water.
