Answer:
Slope Formula: 
Step-by-step explanation:
It is wise to remember this formula. It is one of the most important formulas in Algebra and is fundamental in higher level math courses.
We use this formula to determine the slope, or the average rate of change between 2 points.
Answer:
Part 1) (the missing steps in the explanation)
Part 3) (8, 4); The vertex represents the maximum profit
Part 4) x = 3.58, 0.42
Part 5) x = 6, x = 44; The zeros represent the number of monthly memberships where no profit is made
Part 6) 2(x − 7)2 + 118; x = $7
Part 7) The maximum height of the puck is 4 feet. −(x − 4)^2 + 6
Part 8) (x + 3)^2 − 4
Part 9) 2(x − 1)^2 = 4
Part 10) 8(x − 4)^2 + 592
Step-by-step explanation:
X --- <span>first number
y --- </span><span>second number
x + y = 2x - 15
x - y = 2y - 5
x - 2x + y = -15
x - y - 2y = - 5
-x + y = -15
x - 3y = - 5
-----------------
-2y = -20 /:(-2)
y = 10
</span>x - 3y = - 5 ⇒ x = - 5 + 3y = - 5 + 3 · 10 = - 5 + 30 = 25
Ans.:
x = 25
y = 10
Answer:
Option 3. step 1.
Step-by-step explanation:
Her whole wall is 1=6/6 hence what's not white is 1-2/6=4/6=2/3.
2/3 of her wall is green.
