Answer: y = - 0.4 x - 4.5
Step-by-step explanation:
Equation y=mx+b
m is the slope
x is *ANY* x coordinate
y is *ANY* y coordinate
b is y intercept or WHERE the point is on the Y AXIS
Lets look at the given:
Slope (m) is -2/5
Passes through point 15, -9/2
As you can see, the point goes through the Y axis at (-9/2)
Our equation is y = - 0.4 x - 4.5
Answer:
x = 0.1, y = 0.075
Step-by-step explanation:
Given the 2 equations
27x + 24y = 4.5 → (1)
1.5x + y = 0.225 → (2)
Multiplying (2) by - 24 and adding to (1) will eliminate the y- term
- 36x - 24y = - 5.4 → (3)
Add (1) and (3) term by term to eliminate y
- 9x = - 0.9 ( divide both sides by - 9 )
x = 0.1
Substitute x = 0.1 into either of the 2 equations and solve for y
Substituting into (2)
1.5(0.1) + y = 0.225
0.15 + y = 0.225 ( subtract 0.15 from both sides )
y = 0.075
Answer:
Step-by-step explanation:
well... all the least common factor have to write in the increasing order.
So, following this picture, we have to write in this order:
2 x 2 x 2 x 3 x 5
