Answer:

Prime

Step-by-step explanation:

If we have a point on a pre-image, we can have it labelled as A(x,y)

Now, we can write this as the image

To write this as the image, we simply have to add a mark on the A

This mark is at the upper right

We have it as A’ (x,y)

The part added is called a prime

Answer:

Answer:

7x - 7

Step-by-step explanation:

In this equation you are going to add like terms.

The like terms you have are the terms with x and then the terms without the x.

So 4x + 3x = 7x

5 - 12 = -7

So your answer is 7x-7

Answer:

$52.50

Step-by-step explanation:

Lets use V for Veggie, and H for Ham.

V=4

H=4.50

She is getting 12 sandwiches, and Every 3 H, she buys one V.

So, the order of her buying the sandwiches would be:

H H H V H H H V H H H V

9 H and 3 V

9*H=40.5

3*V=12

40.5+12= $52.50

The total cost of all the sandwiches is given by the equation A = $ 52.50

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total cost of 12 sandwiches be A

Now , the equation will be

For every 1 veggie sandwich 3 ham sandwiches are ordered by Dawn

The cost of veggie sandwich = $ 4.00

The cost of ham sandwich = $ 4.50

So ,

Let the veggie sandwich be = x

Let the ham sandwich be = y

The total number of sandwiches = 12

So , x + 3y = 12

when x = 3 and y = 3

3 + 3 ( 3 ) = 12

3 + 9 = 12

12 = 12

Therefore , the number of veggie sandwich = 3

The number of ham sandwich = 9

And , the cost of 3 veggie sandwich = 3 x 4.00

The cost of 3 veggie sandwich = $ 12

The cost of 9 ham sandwich is = 9 x $ 4.50

The cost of 9 ham sandwich is = $ 40.5

The total cost of 12 sandwich A = cost of 3 veggie sandwich + cost of 9 ham sandwich

Substituting the values in the equation , we get

The total cost of 12 sandwich A = 12 + 40.50

The total cost of 12 sandwich A = $ 52.50

Therefore , the value of A is $ 52.50

Answer:

In this example, if you buy an item at $18.99 with 25% discount, you will pay 18.99 - 4.7475 = 14.24 dollars.

Step-by-step explanation:

Half of 4.50 is 2.25, so for one pound it would be $2.25.

To calculate five pounds, you need to add 2.25+2.25+2.25+2.25+2.25 = 11.25.

For five pounds of strawberry's, it would cost $11.25.

Answer:

The second option, B.

[tex](x| -3< x \leq 2)[/tex]

Explanation:

Since the point on -3 is hollow, this means that -3 is not included in the equation. Therefore, -3 < x. Since the point on 2 is filled, this means that 2 is a valid number that is included in the equation. Therefore, [tex]x\leq 2[/tex].

Answer: B

Step-by-step explanation:

Equation A:

15x - 45 = 75x + 75

=> -120 = 60x

=> x = -2

Equation B:

15x - 45 = 15x + 75

=> 0 = 15

No Solutions

Equation C:

45x - 45 = -15x + 75

=> 60x = 120

=> x = 2

Equation D:

-45x - 45 = -75x + 75

=> 30x = 120

=> x = 4

Step-by-step explanation:

Answer:

(0, 12 )

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (- 5, - 3)

m = [tex]\frac{-3-3}{-5+3}[/tex] = [tex]\frac{-6}{-2}[/tex] = 3 , then

y = 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 3, 3 ), then

3 = - 9 + c ⇒ c = 3 + 9 = 12 ← y- intercept

Thus the line crosses the y- axis at (0, 12 )

Answer:

It crosses the y-axis at the point where y = 12

- the point (0, 12).

Step-by-step explanation:

First we need to find the equation of the line q:

The slope of the line = (-3-3)/(-5-(-3))

= -6/-2

= 3.

Using the point-slope form of a line:

y - y1 = m(x - x1)         Take the point (-3, 3):

y - 3 = 3(x -(-3)

y - 3 = 3x + 9

y = 3x + 12.

Where q crosses the y-axis x = 0 so we have

y = 3(0) + 12

y = 12

The required point is (0, 12).

Volume= 0.96m^3

TSA= 6.56m^2

Step-by-step explanation:

Given data

Length = 2m

Width= 80cm= 0.8m

Height= 60cm= 0.6m

Volume= L*W*H

Volume= 2*0.8*0.6

Volume= 0.96m^3

TSA=2lw+2lh+2hw

TSA= 2*2*0.8+2*2*0.6+2*0.6*0.8

TSA=  3.2+ 2.4+ 0.96

TSA= 6.56m^2

Answer:

3 1/3 Because When we divide two fractions, such as 5/2 ÷ 3/4, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.

Step-by-step explanation:

remember to simplify if ever possible!:D

soooo

in order to do this both fractions has to have the same denominator

so you find the CMD (common denominator)

which is 4

so you'd only change 5/2

5/2 * 2/2 to make it 10/4

now both fractions have the same denominator

you do keep change flip

you keep 10/4

change division to multiplication

and flip 3/4 TO 4/3

which would equal

10/4 * 4/3= 40/12

40/12

and you divide it with long division

you get 3 as ur quotient

divisor as 12

and remainder as 4

= 3 4/12

nd u simplify which u divide 4/12 by 4 and get 1/3

so the answer would be 3 1/3

Answer:

$36.01

Step-by-step explanation:

141.82 - 8.25 = 133.57

133.57-97.56=36.01

The collector earned a total of $36.01 by selling the book.

Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

The collector earned $141.82 - $97.56 = $44.26 by selling the book.

To find the total amount the collector earned, we need to subtract the price they paid for the book from the price they sold it for. This gives us the profit that the collector made on the sale of the book.

However, we also need to subtract the auction fees that the collector had to pay.

The collector paid $8.25 in fees, so their total earnings from the sale of the book were :

⇒ $44.26 - $8.25

Apply the subtraction operation, and we get

⇒ $36.01.

Therefore, the collector made a total of $36.01.

The volume is 418.93 ft^3

Step-by-step explanation:

Here, we want to find the volume of a cone

Mathematically, we use the formula;

V = 1/3 * pi * r^2 * h

r = 5 ft

h = 16 ft

Substituting these values;

V = 1/3 * 3.142 * 5^2 * 16

V = 418.93 ft^3
