Answer:

identification from the table given below. use y = mx + c to solve

Step-by-step explanation:

y = 3x to third

y = 1.5x -7 to second

y =7 to first

y = -1.5x-4 to fifth

y = -3x+4 to fourth

<u>Answer:</u>

Below!

<u>Step-by-step explanation:</u>

Let's use the formula to identify the correct slope and y intercept.

We know that:

Formula = y = mx + b

Option 1: (y = 3x)

Let's compare y = 3x with the formula.

(y = 3x) = (y = mx + b)

<u>We can clearly see that the slope(m) is 3 and the y-intercept(b) is 0.</u>

Final answer: m = 3, b = 0

__________________________________________________________

Option 2: (y = 1.5x - 7)

Let's compare y = 1.5x - 7 with the formula.

(y = 1.5x - 7) = (y = mx + b)

<u>We can clearly see that the slope(m) is 1.5 and the y-intercept(b) is -7.</u>

Final answer: m = 1.5, b = -7

Option 3: (y = 7)

Let's compare y = 7 with the formula.

y = 7 = (y = mx + b)

<u>We can clearly see that the slope(m) is 0 and the y-intercept(b) is 7.</u>

Final answer: m = 0, b = 7

Option 4: (y = -1.5x - 4)

Let's compare y = -1.5x - 4 with the formula.

(y = -1.5x - 4) = (y = mx + b)

<u>We can clearly see that the slope(m) is -1.5 and the y-intercept(b) is -4.</u>

Final answer: m = -1.5, b = -4

Option 5: (y = -3x + 4)

Let's compare y = -3x + 4 with the formula.

(y = -3x + 4) = (y = mx + b)

<u>We can clearly see that the slope(m) is -3 and the y-intercept(b) is 4.</u>

Final answer: m = -3, b = 4

Answer:

Volume of a cup

The shape of the cup is a cylinder. The volume of a cylinder is:

\text{Volume of a cylinder}=\pi \times (radius)^2\times heightVolume of a cylinder=π×(radius)

×height

The diameter fo the cup is half the diameter: 2in/2 = 1in.

Substitute radius = 1 in, and height = 4 in in the formula for the volume of a cylinder:

\text{Volume of the cup}=\pi \times (1in)^2\times 4in\approx 12.57in^3Volume of the cup=π×(1in)

×4in≈12.57in

2. Volume of the sink:

The volume of the sink is 1072in³ (note the units is in³ and not in).

3. Divide the volume of the sink by the volume of the cup.

This gives the number of cups that contain a volume equal to the volume of the sink:

\dfrac{1072in^3}{12.57in^3}=85.3cups\approx 85cups

12.57in

Please help Which of the following inequalities is graphed on the coordinate plane?

Gekata [30.6K]

Answer:

The inequality which represents the graph is y ≤ -2x + 1 ⇒ A

Step-by-step explanation:

To solve the question you must know some facts about inequalities

If the sign of inequality is ≥ or ≤, then it represents graphically by a solid line

If the sign of inequality is > or <, then it represents graphically by a dashed line

If the sign of inequality is > or ≥, then the area of the solutions should be over the line

If the sign of inequality is < or ≤, then the area of the solutions should be below the line

Let us study the graph and find the correct answer

∵ The line represented the inequality is solid

∴ The sign of inequality is ≥ or ≤

→ That means the answer is A or B

∵ The shaded area is the area of the solutions of the inequality

∵ The shaded area is below the line

∴ The sign of inequality must be ≤

→ That means the correct answer is A

∴ The inequality which represents the graph is y ≤ -2x + 1

Clarissa has a budget of $1,200 a month to spend for rent and food. She has already spent $928 this month. Which inequality repr

shtirl [24]

Answer:

1200-928 = 272 for the rest of the month Clarissa has to spend.

Step-by-step explanation:

So we don't want her to go over her budget so we wouldn't choose a greater than option for her so eliminate the first option and the last option. Now we just have the middle two. We want to keep it under 1200 but theres nothing wrong with spending that exact amount each month so I would pick x less than or equal to 272, since we can still equal the total of less than the total and not go over. Option 2 or B.
