Answer: 
Step-by-step explanation:
In slope-intercept form y is isolated
So Let's solve for y.

Step 1: Add -2x to both sides.

Step 2: Divide both sides by 3.

Answer:

Step-by-step explanation:
Exponents are a way of shortening multiplication statements. The exponent represents how many times a term is being multiplied by itself. So, when two terms have the same base it can be written with exponents. For example. 10*10 can be written as
because 10 is being multiplied 2 times. Therefore, if we do this with every term you get
.
Answer:
x ≥ 12
Step-by-step explanation:
Given that :
Total points required = 40
1st round point = 4
2nd, 3rd and 4th round points are identical
Let the point number of points = x
2nd + 3rd + 4th = 3
1st round + 3(x) ≥ 40
4 + 3x ≥ 40
3x ≥ 40 - 4
3x ≥ 36
x ≥ 12
