Answer:
The function that can be used in the online shopping club about its monthly revenue is:
Step-by-step explanation:
First, we're gonna take into account the different values we have in the exercise:
- 10,000 members
- $7 per month for membership
- Loses of 400 members by each $1 monthly increase
How the variable 
represents the price increase, we can do the formula below:
In this formula, we represent in the first part that by each 1 in the variable , the total of members will be reduced in 400, in the second part, we mention that at the same time, the membership fee will be increased in the same value of . Now we must simplify this function:
We operate the values:
Solve we can:
And organize:
At the end, how 
represents the monthly revenue received by the club, we use that variable for our formula:
Answer:
424 cm²
Step-by-step explanation:
The figure is composed of a square and a trapezium on top
A of square = 18² = 324 cm²
A of trapezium = 
h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 8, b₁ = 18 and b₂ = 7 , then
A = 0.5 × 8 × (18 + 7) = 4 × 25 = 100 cm²
Area of hexagonal park = 324 + 100 = 424 cm²
It was 11 hours because if the temperature drops 2 degrees after every hour, after 11 hours, the temperature would have dropped 22 degrees and 62 - 22 = 40.
Answer- 3x-56(x) =8
Explanation- Good luck
Answer:
<u>y=6x-4</u>
Step-by-step explanation:
<u>What we know</u>
- the slope is 6
- our point is (-9,-58)
-9 is x and -58 is y so we have to find the y-intercept y=mx+b is also the formula for this
-58=6(-9)+b
-58=-54+b
-58=54+b - we changed -54 to a positive 54
54-58=-4
y=6x-4
