-Graphing Linear equalities with slope and y-intercept-

Answers

Answer 1

Answer:

slope = 1

y-intercept = -3

equation: y = x - 3

Step-by-step explanation:

slope = (y₂ - y₁) / (x₂ - x₁)

choose any 2 consecutive x. y pairs and plug the numbers into the equation. I pick (0, -3) and (1, -2)

slope = (-2 - -3 / (1 - 0) = 1/1 = 1

y-intercept = -3 this is where the line crosses the y axis at point (0, -3)

Equation: y = mx + b = (1)x + (-3) = x - 3

y = x - 3

To draw the graph, it's easy (sorry, Brainly doesn't provide drawing tools):

put the first point at (0, -3) then go up 1, over 1, up 1, over 1, etc. because the line has a slope of 1/1.

the line should slant up because it has a positive slope

A roll of 40 quarters weighs 8 ounces. Which proportion can be used to find the weight in ounces, w, of 200 quarters?

A. 40/8 = 200/w
B. 40/w = 8/200
C. 40/200 = w/8
D. 40/8+w = w/200

Answers

Answer:

The answer is A. 40/8=200/w

Step-by-step explanation:

This works because the corresponding proportions are in the same place in each fraction. 40 is the number of quarters and it is the numerator. 200 is also the number of quarters and is the numerator. The same goes for 8 and w being the denominators.

If you were to finish solving the problem, you'd get w=40.

It's d 40/8 +W = W/200

Answers

Answer:

B. 8=2+2a and 3=a

Step-by-step explanation:

1. Look at the scale. On the left side we have 8, on the right side we have 2a + 2.

The two balance each other out perfectly, therefore they're equal.

2. We write our equation.

8=2a+2

3. we substract 2 from the right side so only the '2a' will be left. but if we do something to the right side, we do the same to the left. So, -2 from both sides.

8=2a+2 /-2

6=2a

4. Now we know that 2a=6, but we need to know much much one 'a' is, so we divide by 2.→ divide both sides by 2, so only the 'a' is left on one side, and only a number on the other.

6=2a. /÷2

3=a → this is your answer.

A convenience store sells prepaid mobile phones. It purchases them for $12 each and uses a markup rate of 250%.

What is the markup rate in decimal form?

The markup rate is the constant of proportionality in the equation y=kx
. Write an equation that can be used to find the markup on the cost x
of a phone.

Using the equation, calculate the markup amount.

What is the retail price of a phone?

Next week the store is going to reduce the price to $31.50. Calculate what percent the sale price is of the retail price.

Think of the retail price of the phone as 100%. How does the sale price compare to the retail price? What does this tell you about the markdown rate? The sale price is ??% less than the retail price. The markdown rate is ??%.

What is an equation in the form y=kx that relates the sale price to the retail price x?

Answers

The markup rate in decimal form is 2.50 (250% = 2.50).

An equation that can be used to find the markup on the cost x of a phone is y = 2.50x, where y represents the markup amount.

Using the equation, the markup amount can be calculated as y = 2.50($12) = $30.

The retail price of a phone is the cost price plus the markup amount, which is $12 + $30 = $42.

The percent the sale price of $31.50 is of the retail price $42 can be calculated as (31.50/42) x 100% = 75%.

The sale price is 25% less than the retail price. Therefore, the markdown rate is 25%.

An equation in the form y=kx that relates the sale price to the retail price x is y = 0.75x, where y represents the sale price.

The vertices of a figure are given. Draw the figure and its rotation as described. Identify the coordinates of the image.
P(−3, 4), Q(−1, 4), R(−2, 1), S(−4, 1)
180° about vertex R

Answers

Answer:

Step-by-step explanation:

The coordinates of the vertices of △PQR are P(−3,4), Q(−3,1), and R(−1,1). The coordinates of the vertices of △P′Q′R′ are P′(−6,−5), Q′(−6,−1), and R′(−4,−1)

Which statement correctly describes the relationship between △PQR

and △P′Q′R′ ?

A.) △PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′

using a reflection across the x-axis followed by a translation 3 units to the left, which is a sequence of rigid motions.

B.) △PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′

using a translation 3 units to the left followed by a reflection across the x-axis, which is a sequence of rigid motions.

C.) △PQR is not congruent to △P′Q′R′ because there is no sequence of rigid motions that maps △PQR to △P′Q′R′

D.) △PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′ using a reflection across the x-axis followed by a translation 1 unit down, which is a sequence of rigid motions.

The image of the figure is added as an attachment

How to determine the image of the figure

From the question, we have the following parameters that can be used in our computation:

P(−3, 4), Q(−1, 4), R(−2, 1), S(−4, 1)Rotation by 180° about vertex R

The rule of 180 degrees rotation is

(x, y) ⇒ (-x, -y)

Represent the rotation point R with (a, b)

So, we have

(x, y) ⇒ (-(x - a) + b, -(y - b) + a)

We have

R = (a, b) = (-2, 1)

This gives

(x, y) ⇒ (-(x + 2) + 1, -(y - 1) - 2)

(x, y) ⇒ (-x - 1, -y - 1)

Using the above as a guide, we have the following:

P' = (3 - 1, -4 - 1) = (2, -5)

Q' = (1 - 1, -4 - 1) = (0, -5)

R' = (2 - 1, -1 - 1) = (1, -2)

S' = (4 - 1, -1 - 1) = (3, -2)

See attachment for the image of the point
