Answer:

$2 price per pound

2 is the constant of proportionality

Step-by-step explanation:

Price of Cherries = $2 per pound

what is the constant of proportionality

If y = total cost of buying x pounds of Cherries at $2 per pound

The equation below represent the situation

y = $2 * x

y = 2x

The constant of proportionality is 2

That is, the $2 price per pound

Answer:

Mia is right

Step-by-step explanation:

the red graph is a negative slope. y=4+6x is a positive slope.

Answer:

Mia

Step-by-step explanation:

If you plot in any number (say 1) for x, then y will equal 10 (4+6(1)). The blue dotted line shows that as it approaches 1 on the x axis, it approaches 10 on the y axis. However, the red line shows that when x=1, y is about 3.5

Thus Mia is correct

Answer:

Y=3x + 5

Step-by-step explanation:

Answer: Option D.

Step-by-step explanation:

We have the inequality:

Id - 3.5I ≤ 1.5

remember that : IxI < d means that:

-d < x  < d

Now let's find the possible values of d, breaking the absolute value we have that:

-1.5 ≤ d - 3.5 ≤ 1.5

adding 3.5 in each part, we have:

-1.5 + 3.5 ≤ d - 3.5 + 3.5 ≤ 1.5 + 3.5

2 ≤ d ≤ 5

Then d can be any value in the set [2, 5]

Then the correct graph is D, because the purple line starts at 2, and ends at 5.

Answer:

1. 48 stickers 2. 1.2 miles

Step-by-step explanation:

1. 12x4=48 stickers. 2. If we let w denote the length of the morning walk, Sierra walks w+2.5w or 3.5w miles each day. At the end of the week she has walked 7 times as far and she said that this was 30 miles. Solving the equation

24.5w=30,

we have w=30/24.5≈1.2 miles. Therefore the distance of Sierra's morning walk is about 1.2 miles

Solution: Using a diagram

We can illustrate the solution to this problem with a tape diagram. If we let one box be the morning walk, then the evening walk is 2.5 boxes. The total distance Sierra walks in one day is represented by 3.5 boxes. Instead of talking about the number of boxes, we can choose a variable to represent the value or length of each box, say w.

Since Sierra walks every day of the week, the total distance walked is 7 times as long. Therefore, we have the total distance walked during the week is 7(3.5w)=24.5w. We know that Sierra walks a total distance of 30 miles, so we have 24.5w=30 miles. We can use another diagram to illustrate the total distance with 24.5 boxes.

Dividing both sides of the equation 24.5w=30 by 24.5 allows us to find w, and we have

w=30/24.5≈1.2.

Therefore, Sierra's morning walk is about 1.2 miles.

Answer:

Use the slope formula to find the slope  m.

 m = 0

Step-by-step explanation:

The slope of the line is zero (0).

Given the following points:

To find the slope of the line, we would use the following formula;

[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Substituting the points into the formula, we have;

[tex]Slope. \;m = \frac{5 - 5}{-9 - 8}\\\\Slope. \;m = \frac{0}{-17}\\\\Slope. \;m = \frac{0}{-17}[/tex]

Slope, m = 0

Therefore, the slope of the line is zero (0).

Answer:

2 x 11  x 17  = L x W x H

Step-by-step explanation:

x² + 12 (8) - 160 = 0

8(8) + 96 -160 = 0

8(8) + 96 -160  

160 -160 = 0

x² + 12x -160 = 0  

x² + 8 × - 20 = 0  

(x +8) (x-20)

2( x+3 ) × (x+9) = 374

(x+3) × (x+9) = 374 ÷ 2

(x+3)× (x+ 9) = 187

x² = 184 - 9

x² = 175

x = 175/25

x = 8

Formula of Volume of Cuboid  

V = L ×W × H

V = 2 × (x+3) × (x+9)

2 ( 8+3 ) × ( 8+ 9)

2 (11) × (17)

x + 3 = 11

x + 9 = 17

Volume L × W × H

2 × 11 × 17 = 374cm³

Answer:

A translation can map one angle onto another since dilations preserve angle measures of triangles.

Step-by-step explanation:

A translation transformation could be used to prove the figures are similar using the AA similarity postulate because it can map one angle onto another since dilations preserve angle measures of triangles.

In a translation transformation, every point of the figure is moved by the same quantity. This means that the angles and lengths of the figure remain the same. The only thing that changes are the points on which it lies.

Translation transformation is the correct answer. This is because, in translation transformation, only the cartesian coordinates of the figure change. Nothing happens to the angles and lengths of the figure.

In the other given transformations, the orientations of the figures are not preserved and this makes it harder to prove using the AA similarity postulate.

Therefore, we have found that a translation transformation could be used to prove the figures are similar using the AA similarity postulate because it can map one angle onto another since dilations preserve angle measures of triangles.

Answer:

C) -10 * (- 8) = 80

Step-by-step explanation:

(- 10) * (½) * (- 8)

Checking all the options

A) (½) * - 8 = - ( - 8/16 )

1/2 * - 8

= -8/2

= -4

(½) * - 8 = -4

(½) * - 8 = - ( - 8/16 ) Wrong

B) (-10) * (½) = 5

-10 * 1/2

= -10/2

= -5

(-10) * (½) = -5

(-10) * (½) = 5 Wrong

C) -10 * (- 8) = 80

-10 * (- 8)

= -10 × - 8

= + 80

-10 * (- 8) = 80 Correct

D) -8 * 2 = - 16

-8 * 2

= -16 correct but we don't have 2 in the expression so, it is wrong

The correct way to start solving the problem is C) -10 * (- 8) = 80

(- 10) * (½) * (- 8)

-10 * (- 8) = 80

80 * 1/2 = 80 / 2
