The earnings of Jack by the function assuming x as time spent from 2.30 PM will be $53.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
As per the given function,
f(x) = 10x + 8
Time spent working x = 7:00 PM - 2:30 PM
x = 4.50 hour
f(4.30) = 10(4.50) + 8
f(x) = $53
Hence "The earnings of Jack by the function assuming x as time spent from 2.30 PM will be $53".

triangle A'B'C is created by dilating triangle ABC by a scale factor of 4. what is the length of AB? The length of A'B'
Answer:
The length of AB is 20 units
Step-by-step explanation:
The given parameters from the graph for coordinates A and B are;
The coordinates of the point A = (1, 4)
The coordinates of the point B = (4, 8)
The length of segment AB is given by the equation for finding the distance, d between two points given their coordinates as follows;
[tex]d = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Where;
(x₁, y₁) = (1, 4)
(x₂, y₂) = (4, 8)
Substituting gives;
[tex]d_{AB} = \sqrt{\left (8-4 \right )^{2}+\left (4-1 \right )^{2}} = \sqrt{25} = 5[/tex]
The length of [tex]\overline {AB}[/tex] = 5
Therefore, given that ΔA'B'C is created by dilating ΔABC by a scale factor of 4, the length of A'B' = 4 × The length of AB
Therefore, the length of [tex]\overline {A'B'}[/tex] = 4 × The length of [tex]\overline {AB}[/tex] = 4 × 5 = 20
The length of [tex]\overline {A'B'}[/tex] = 20 units.

How much does one slice of pumpkin pie cost if there are 8 servings per pie?
Ingredients
• Pumpkin 15oz can ($1.50 for 15oz can)
2 eggs ($2.59 for one dozen)
• 1 tsp pumpkin pie spice ($5.99 for 1.12oz Jar =
approx.6tsp)
• Evaporated Milk 14oz can ($1.25 for 14oz can)
• Pillsbury Pie Crust ($3.79 for two crusts)
Show Your Work Here:
Answer:
$0.76 per serving of pumpkin pie
Step-by-step explanation:
the total cost of the ingredients needed to prepare a pumpkin pie = $1.50 + ($2.59 / 6) + ($5.99 / 6) + $1.25 + ($3.79 / 2) = $6.075
if we cut 8 servings per pie, then the cost per serving = total cost of the pie / number of servings = $6.075 / 8 = $0.759375 ≈ $0.76 per serving of pumpkin pie
We want to find the cost of each slice of a pie given that we know the price of the ingredients that we use to make the whole pie. We will see that the cost of a single slice is $0.75.
First, we must get the cost of the whole pie. We have:
$1.50 for the 15oz can of PumpkinWe know that 12 eggs cost $2.59, then 2 eggs cost: (2/12)*$2.59 = $0.43.We know that 1.12 oz of pie spice costs $5.99, and we use only one teaspoon of this, remember that: 1tsp = 0.167 oz, Then the cost of 1tsp of pie spice is: (0.167 oz)/(1.12 oz)*$5.99 = $0.89.$1.25 for the 14oz can of evaporated milk.One pie crust, we know that two of them cost $3,79, then only one costs: $3.79/2 = $1.90The total cost is then:
C = $1.50 + $0.43 + $0.89 + $1.25 + $1.90 = $5.97
Now we know the total cost of the pie, and it has 8 slices, then each slice costs: $5.97/8 = $0.75

Bill has two fat cats. He feeds each cat 150 grams of dry food each, twice a day. If he buys a 5 kilogram bag of dry food, about how many days will the bag last?
Answer: 4 days (I think)
Step-by-step explanation:
One cat = 150*2 = 300g
Two cats = 600g
600*2 = 1200 (this is the total amount of food they both eat in a day)
5kg = 5000g
1200g/5000g = 4.17
The bag will last 4 days.
Janine's family is designing a new garage. Use A l w to determine the area of the garage if the length l is 24 feet and the width w is 22 feet. Find the area A of the garage in square feet.
Given :
Length of garage, l = 24 feet.
Width of garage, w = 22 feet.
To Find :
Area of garage in square feet.
Solution :
We know, area of a rectangular shape is given by :
Area = l × w
Area = 24 × 22 feet²
Area = 528 feet²
Therefore, area of garage is 528 feet².
Hence, this is the required solution.

Which of the following
represents a function?
PLEASE HELP 15 POINTS OR BRAINLIEST JUST ASK PLEASE HELP ME
Answer:
A: represents a function
Explanation:
Every other option, A, has two y for one x.
It can be a function if there is 1x for 1y.
If this was helpful, please mark brainliest. Have a beautiful day!
Choice A is not a function because x = 2 leads to more than one y value (y = 1 and y = 7 at the same time)
Choice B is not a function for similar reasoning. Here we have x = 1 lead to y = 2 and y = 5 simultaneously.
Choice D is also not a function because of the two points (5,2) and (5,4). This tells us we have x = 5 lead to y = 2 and y = 4 at the same time.
A function is only possible if you have any input lead to exactly one output. Choice C shows this. Note how it passes the vertical line test. It is impossible to draw a vertical line through more than two points on the function curve.

Using the substitution of (y=y) what is y= -3x+5 y= -2x+3 (pls help this is)
Answer:
x = 2 and y = -1
Step-by-step explanation:
y = -3x + 5
y = -2x + 3
-3x + 5 = -2x + 3
Add 2x to both sides;
-x + 5 = 3
Subtract 5 from both sides;
-x = -2
Divide both sides by -1
x = 2
Solve for y;
y = -3x + 5
y = -3(2) + 5
y = -6 + 5
y = -1

Step 1: Simplify both sides of the equation.
−2(−9x+5)−4x=2(x−5)−4
(−2)(−9x)+(−2)(5)+−4x=(2)(x)+(2)(−5)+−4(Distribute)

In math formulas, A and a, always represent the same number.
Answer: False
Step-by-step explanation:
In math formulas, we want to use different symbols to represent different things.
While in linguistics, A and a represent the same thing, the symbols are different, then we can use them to represent different things.
For example, we can define a square of side length a.
And the area of that square will be equal to the square of its side length, we can represent the area with A, such that:
A = a^2.
Here A and a are different numbers (and also represent different measures, a is in units of length and A is in units of surface).
Then the statement is false.
