Answer:
- 749.5i + 10821.5
−2669.5
−4168.5
Step-by-step explanation:
Given tgat:
Number of stores in 2003 (y2) = 1078
Number of stores in 1999 (y1) = 4076
1999 = i = 9
2003 = 13
y - y1 = m(x - x1)
m = slope = (y2 - y1) / (i2 - i1)
m = (1078 - 4076) / 13 - 9
m = - 2998 / 4
m = - 749.5
y - 4076 = - 749.5(i - i1)
y - 4076 = - 749.5(i - 9)
y - 4076 = - 749.5i + 6745.5
y = - 749.5i + 10821.5
Prediction for 2008 and 2010
2008 ; i = 18
y = - 749.5(18) + 10821.5
y = −2669.5
2010 ; i = 20
y = - 749.5(20) + 10821.5
y = − 4168.5

A rubber bouncy ball is bouncing up and down such that the ball's distance, d, in feet above the ground is given by the inequality
Which of the following graphs shows all the possible distances?
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:
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

find the slope: (8,5) and (-9,5)
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:
Points on the x-axis = (8, -9)Points on the y-axis = (5, 5)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).

1.Bella brought stickers to give to 12 of her friends. Each friend received 4 stickers. How many stickers did she bring to school?
2.ierra walks her dog Pepper twice a day. Her evening walk is two and a half times as far as her morning walk. At the end of the week she tells her mom,
I walked Pepper for 30 miles this week!
How long is her morning walk if there are 7 days in the week?
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.
Below are different ways students tried to start this problem. Which is correct?
(- 10) * (½) * (- 8)
A) (½) * - 8 = - ( - 8/16 )
B) (-10) * (½) = 5
C) -10 * (- 8) = 80
D) -8 * 2 = - 16
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
= 40

If a figure has been dilated by a scale factor of one third, which transformation could be used to prove the figures are similar using the AA similarity postulate? A translation because it can map one angle onto another since dilations preserve angle measures of triangles. A rotation because it can change the orientation of a figure since dilations do not preserve orientation. A dilation because it can map one side onto another since dilations preserve side length of triangles. A reflection because it can change the orientation of a figure since dilations do not preserve orientation.
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.
What is translation?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.
The transformation that could be used to prove the figures are similar using the AA similarity postulate is given below: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.

a cuboid with a volume of 374cm^3 has dimensions
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
