Answer:
R = 35l-215
Step-by-step explanation:
total amount they earn = 35l
however, to account for the money used to rent the machines, we have to deduct 215 from the total cost.
hence,
<u>R= 35l-215</u>
total amount they raised = 35(26)-215 = <u>$695</u>
they would lose <u>$215</u> if they were unable to aerate due to weather conditions
they could avoid this potential loss by <u>checking the weather report before renting the machines</u>
Answer: x= 2/5, 20
Step-by-step explanation:
5x+8=10
1. subtract 8 on both sides
5x = 2
2. divide 5 on both sides
x = 2/5
10x+16
x = 2/5
1. substiuite x for 2/5
10 times 2/5 +16
4 + 16
= 20
Angle B corresponds to angle Y
Answer:
All the intervals that contain the number are solution of the problem
Step-by-step explanation:
we know that
The equation of a vertical parabola into vertex form is equal to
where
(h,k) is the vertex of the parabola
In this problem we have
Convert to vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
-------> equation in vertex form
The vertex is the point
The x-coordinate of the vertex is
