Answer:
The equation of line is: y = 7
Step-by-step explanation:
point = (-8, 7)slope = 0Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope, and (x₁, y₁) is the point
substituting the values m = 0 and the point (-8, 7)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-7 = 0(x-(-8))[/tex]
[tex]y-7 = 0[/tex]
[tex]y = 7[/tex]
Thus, the equation of line is: y = 7

9. Mario found the composite function (hºg)(x), where h(x) = 4 -
- ž, and g(x) = 2x + 10.
State which step he made the error and explain the mistake he made in his reasoning,
(2x + 10)
Step 1: h(g(x)) = 4 -
2
Step 2: h(g(x)) = 4 - x + 10
Step 3: h(g(x)) = 14 - X
a. Step 1: 2(4 - Ž)+10
b. Step 2: h(g(x)) = 4 - x + 5
c. Step 2: h(g(x)) = 4 - x-5
d. no error
Answer:
The mistake is in step 2
Step-by-step explanation:
We are given h(x)=4-x
Note: Considering h(x)=4-x as in question given there is some issue. If value of h(x) is different the answer would be different.
and g(x)=2x+10
We need to find h(g(x))
h(g(x)) can be found by putting the value of g(x) in h(x)
Steps used by Mario are:
Step 1: h(g(x)) = 4 - x
Step 2: h(g(x)) = 4 - x + 10
Step 3: h(g(x)) = 14 - X
She did mistake in step 2:
The step 2 should be:
h(g(x))=4-(2x+10)
h(g(x))= 4-2x-10
h(g(x))=-6-2x
So, the mistake is in step 2

C.B. Clothing ordered sweaters at a wholesale cost of $20 each. The store marked up the price 50 percent above the wholesale cost to use as their selling price. After every month that the sweater didn't sell, the store reduced the selling price by 20 percent. After how many monthly price reductions did the price dip below the wholesale cost? after 1 monthly price reduction after 2 monthly price reductions after 3 monthly price reductions after 4 monthly price reductions
Answer: after 2 monthly price reductions
Step-by-step explanation:
Given that :
Wholesale cost = $20 each
Markup = 50%
Selling price = $20 + (50% * 20) = $30
After each month selling price reduces by 20%;
Dip in price per month for which item didn't sell ;
Let m = Number of months
$30 - 0.2(30)m = $30 - 6m
After how many monthly price reductions did the price dip below the wholesale cost?
$30 - 6m < $20
-6m < $20 - $30
-6m < - $10
m > 10/6
m > 1.667
m = 2
After 2 monthly price reduction

The intensity,I, of light received at a source varies inversely as the square of the distance, d, from the source. If the light intensity is 33 foot-candles at 20 feet, find the light intensity at 5fee
Answer:
The light intensity is 528 foot-candles at 5 feet
Step-by-step explanation:
If x and y are in inverse variation, then x y = k, where k is the constant of variation
In the given question
∵ The intensity I, of light received at a source, varies inversely as the
square of the distance d, from the source
→ That means I × d² = k, where k is the constant of variation
∴ I × d² = k
∵ I = 33 foot-candle at d = 20 feet
→ Substitute them in the rule above to find k
∴ 33 × (20)² = k
∴ 33 × 400 = k
∴ 13200 = k
→ Substitute the value of k in the equation
∴ I × d² = 13200 ⇒ equation of variation
∵ d = 5
→ Substitute it in the equation to find I
∵ I × (5)² = 13200
∴ I × 25 = 13200
→ Divide both sides by 15
∴ I = 528
∴ The light intensity is 528 at 5 feet

Maya and Edward cut lawns in the summer to earn spending money. Maya has a newer lawnmower, so Edward takes 15 minutes longer to cut a lawn than Maya. Working together they can both cut a lawn in 18 minutes. How long would it take Edward to cut a lawn alone?
Answer:
The answer would be 45 minutes.
Step-by-step explanation:
Just skipped to the answer on Edementum.
A fraction is a way to describe a part of a whole. The time it takes Edward to cut the lawn alone is 45 minutes.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Let the time taken by Maya to lawn the garden be x.
The rate at which Maya lawn = 1/x
Maya has a newer lawnmower, so Edward takes 15 minutes longer to cut a lawn than Maya. Therefore,
The rate at which Edward lawn = 1/(x+15)
Working together they can both cut a lawn in 18 minutes.
The rate at which they both work = 1/18
Now, the rate of working can be compared as,
1/x + 1/(x+15) = 1/18
(x+ x + 5)/x(x+15) = 1/18
(2x + 15)18 = x(x+15)
36x + 270=x² + 15x
x²-21x-270=0
x = 30, -9
Since time can not be negative. Therefore, the time it takes Edward to cut the lawn alone is,
x + 15
= 30 + 15
= 45 minutes
Hence, the time it takes Edward to cut the lawn alone is 45 minutes.

The amount of concrete, c, needed to make a walkway around a circular swimming pool varies directly as the square of the diameter, d, of the
pool. Which statement is true?
OA If the diameter of the pool is doubled, the amount of concrete needed is multiplied by 2.
•B. If the diameter of the pool is doubled, the amount of concrete needed is multiplied by 4.
OC. If the diameter of the pool is halved, the amount of concrete needed is multiplied by 2.
OD. If the diameter of the pool is halved, the amount of concrete needed is multiplied by 4.
Answer:
Step-by-step explanation:
For all Plato users
The amount of concrete needed after doubling the diameter of the circle will be multiplied by 4 by the initial amount. Hence, the correct option is (B).
What are direct proportions?Direct proportions are the proportions where a variable changes with another variable by direct mean so the coefficient of constant will be direct.
For example y ∝ x² here y varies with respect to x square.
y = Kx² where k will be the coefficient of constant.
Given that amount is Amount ∝ d²
Amount = k d²
By doubling the diameter
Amount = k (2d)²
Amount = 4 kd²
Amount = 4 × initial amount hence, the amount will be multiplied by 4.

The lengths of two sides of a triangle are 4 cm and 13 cm. Identify the range of possible lengths for the third side.
Answer:
9cm<x<17cm
Step-by-step explanation:
your welcome
The range of the possible lengths for the third side is 9 cm < x < 17 cm.
What is Triangle?A triangle is a geometrical shape which has three vertices, three edges and three angles. In other words, in Euclidean geometry, a triangle is defined as a two dimensional shape which is three non-collinear points lying on a unique plane.
The sum of the interior angles of a triangle is 180 degrees.
Here we have lengths of two sides of a triangle which are 4 cm and 13 cm.
If the length of two sides of a triangle are given, then the length of third side will lie in the range between the difference of the other two sides and the sum of the other two sides.
Let x represents the third side of the triangle.
So, here the third side lies between 13 cm - 4 cm and 13 cm + 4 cm.
13 - 4 < x < 13 + 4
9 < x < 17
Hence the range of possible lengths for the third side of the triangle is in between 9 cm < x < 17 cm.
