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.

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.

The expression for total change in Anaya's account on Monday is [tex]-10.50\times 3[/tex] or [tex]3\times (-10.50)[/tex].

Important information:

Value of one entry is [tex]-\$10.50[/tex].

It means, the change in account by one entry is [tex]-\$10.50[/tex].

The value of three entries is the product of the value of one entry and 3.

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

Answer:

B! Since Its not positive, it is negative, so its -6. Hope this helps!

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.

The earnings of Jack by the function assuming x as time spent from 2.30 PM will be $53.

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".

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:

The 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
