A car maintains a speed of 23 mi/h for 5 seconds. It then accelerates to a speed of 46 mi/h in 5 seconds. It maintains that speed for the next 5 seconds. Which graph shows the car’s speed over time?
Solution:
The graph is Time versus Speed.
In figure (a), the graph has a speed or y-axis=23mi/h for time or x-axis=5seconds.
The car maintains a speed of 23mi/h for 5 seconds.
For next 5 seconds, in figure a the graph increases linearly or we have a acceleration and reaches to 46mi/h.
It accelerates to a speed of 46 mi/h in 5 seconds.
It maintains that speed for the next 5 seconds. In figure (a), after we reach speed=46mi/h, there is a straight line for 5 seconds at speed=46mi/h.

Ellen is drawing two polygons one of the polygons has 3 more angles than the other what shape could she be drawing
Answer:
Step-by-step explanation:
The attachment shows different types of polygons.
Now depending on these we have following five possibilities:
Case 1: Triangle and hexagon
If first polygon is triangle with three angles, the second will have 6 angles and the second polygon will be hexagon.
Case 2: Quadrilateral and heptagon
If first polygon is quadrilateral with 4 angles, the second will have 4+3 =7 angles and the second polygon will be heptagon.
Case 3: Pentagon and Octagon
If first polygon is pentagon with 5 angles, the second will have 5+3=8 angles and the second polygon will be octagon.
Case 4: Hexagon and Nonagon
If first polygon is hexagon with 6 angles, the second will have 6+3=9 angles and the second polygon will be nonagon.
Case 5: Heptagon and Decagon
If first polygon is Heptagon with 7 angles, the second will have 7+3=10 angles and the second polygon will be decagon.
Depend on the possibilities, which figure Ellen is drawing.
What is polygon?A closed, two-dimensional form with straight line segments is called a polygon. It does not have three dimensions. A polygon has flat surfaces throughout. A polygon must have three sides at a minimum. Only at its terminal must each side of a line segment cross another line segment. Depending on a polygon's number of sides.
Given Ellen is drawing two polygons one of the polygons has 3 more angles than the other,
Now, based on these, there are the five options listed below:
Case 1: Hexagon and triangle
If the first polygon is a triangle with three angles, the second polygon will be a hexagon with six angles.
Case 2: Heptagon and quadrilateral
If the first polygon has a quadrilateral shape and four angles, the second polygon will have four plus three more angles, making it a heptagon.
Pentagon and Octagon in Case 3
If the first polygon has a pentagon shape with five angles, the second will have an octagon shape with five plus three equals eight angles.
Hexagon and Nonagon in Case 4
If the first polygon has a hexagon shape and 6 angles, the second will have 6 + 3 = 9 angles and be a nonagon.
Heptagon and Decagon in Case 5
if the initial polygon is a hexagon, then The first polygon has 7 angles, the second has 7+3=10 angles, and the third is a decagon.
Hence the shape of polygon depend on these possibilities.

Is the system of equations is consistent, consistent and coincident, or inconsistent? y=4x−4 y=−4x+4 Select the correct answer from the drop-down menu.
If a system has exactly one or infinite number of solutions then it will be a consistent system.
So, we can solve the given system of equation to get the answer.
y=4x−4 ................(1)
y=−4x+4...............(2)
After equating both the equations we will get,
4x-4= -4x+4
4x-4+4x=4 (Adding 4x to each sides).
8x-4=4
8x=4+4 (Adding 4 to each sides).
8x=8
8x/8=8/8 ( Dividing each sides by 8).
x=1
Now pluging x=1 in equation (1). So,
y=4x−4
=4(1)-4
=4-4
=0
Hence the solution of the given system is (1, 0) which also means that the two equations is intersecting at a point(1,0).
So, the given system is consistent and coincident.
Answer:
The answer is " Consistent And Independent"
Why? :
When 2 Lines intersect at one point it means it Consistent and Independent
and When the Lines are the same exact thing its Consistent and Dependent
But, when 2 lines don't intersect at all its inconsistent. :)

Gabriel wants to solve the equation 5/8 m=25. What step should he do to get m by itself on one side of the equation?
Final answer:
To solve the equation 5/8 m = 25, Gabriel needs to multiply both sides of the equation by the reciprocal of 5/8, which is 8/5, to isolate m on one side. The result after simplification is m = 40.
Explanation:
To solve the equation 5/8 m = 25, Gabriel needs to isolate the variable m on one side of the equation. He should start by multiplying both sides of the equation by the reciprocal of the fraction that is multiplied by m, which is 8/5. Here's the step-by-step process:
Multiply both sides of the equation by 8/5 to cancel out the 5/8 on the left side:
(8/5) × (5/8) m = (8/5) × 25
Simplify the left side by canceling out the common factors in the fraction:
1 m = (8/5) × 25
Next, multiply the number 25 by 8/5 to find the value of m:
m = 25 × (8/5) = 40
Thus, the solution to the equation is m = 40.

Ling must spend no more than $40.00 on decorations for a party. She has spent $10.00 on streamers and wants to buy bags of balloons as well. Each bag of balloons costs $2.50. The inequality below represents x, the number of bags she can buy given the spending limit and how much she has already spent on streamers.
10+2.5X_<40
Which best describes the number of bags of balloons she can buy?
A.She can buy from 0 to 12 bags, but no more.
B.She can buy from 0 to 20 bags, but no more.
C.She must buy 12 or more bags.
D.She must buy 20 or more bags.
Answer:
Option A is the correct choice.
Step-by-step explanation:
We have been given that Ling must spend no more than $40.00 on decorations for a party. She has spent $10.00 on streamers and wants to buy bags of balloons as well. Each bag of balloons costs $2.50.
The inequality [tex]10+2.5x\leq 40[/tex] represents x, the number of bags she can buy given the spending limit and how much she has already spent on streamers.
Let us solve for x by subtracting 10 from both sides of our inequality.
[tex]10-10+2.5x\leq 40-10[/tex]
[tex]2.5x\leq 30[/tex]
Now we will divide both sides of our inequality by 2.5.
[tex]\frac{2.5x}{2.5}\leq \frac{30}{2.5}[/tex]
[tex]x\leq 12[/tex]
Therefore, Ling can buy from 0 to 12 bags, but no more and option A is the correct choice.
You buy 8 packs of markers with 20 markers in each pack. You already had 10 markers. Which equation shows how to calculate the total number of markers, m, you have?
Answer: [tex]m= 8(20)+10[/tex]
Step-by-step explanation:
Given : The number of markers in each of 8 pack = 20
Then, the number of markers in 8 packs = 8 x 20 = 8(20)
Also, You already had 10 markers.
Then, the total markers you have now = Number of markers in 8 packs+ 10
= 8(20)+10
If we denote the total number of markers be 'm'.
Then, the required equation will be :-
[tex]m= 8(20)+10[/tex]
Hence, the equation shows how to calculate the total number of markers, m, you have : [tex]m= 8(20)+10[/tex]

Kasimir rode his bike 34,478 centimeters. He converts the distance to kilometers. His work is shown below.
A.Kasimir should have divided by 10,000.
B.Kasimir should have multiplied by 100.
C.Kasimir should have divided by 100,000.
D.Kasimir should have multiplied by 0.001.
Answer:
c) Kasimir should have divided by 100,000.
Step-by-step explanation:
Given that Kasimir rode his bike 34,478 centimeters.
We have the table
10 mm=1 cm
10 cm =1dm
10dm = 1 m
...
Hence we have 100 cm = 1 m
100x1000 cm = 1 km
1 km = 34478/100000 = 0.34478
Hence C) is right
Kasimir should have divided by 100,000.
The average rate of change from x = 0 to x = 15 is about −4.667. How does the average rate of change from x = 0 to x = 20 compare to this number?
Suppose that the height of the slide is 2 feet, when x = 20. What is the average rate of change over the entire slide?
The average rate of change over the entire slide is -0.05.
The average rate of change from x = 0 to x = 15 is calculated by finding the slope of the secant line that intersects the graph of the function at x = 0 and x = 15.
The slope of the secant line is:
m = ([tex]y_2[/tex] - [tex]y_1[/tex])/([tex]x_2[/tex] - [tex]x_1[/tex])
= (-2 - 15)/(15 - 0)
= -17/15
= -1.133
The average rate of change from x = 0 to x = 20 is calculated by finding the slope of the secant line that intersects the graph of the function at x = 0 and x = 20.
The slope of the secant line is:
m = ([tex]y_2[/tex] - [tex]y_1[/tex])/([tex]x_2[/tex] - [tex]x_1[/tex])
= (2 - 15)/(20 - 0)
= -13/20
= -0.65
The average rate of change from x = 0 to x = 20 is smaller than the average rate of change from x = 0 to x = 15.
This is because the slope of the secant line is getting closer to 0 as the interval gets larger.
If the height of the slide is 2 feet when x = 20, then the average rate of change over the entire slide is:
m = ([tex]y_2[/tex] - [tex]y_1[/tex])/([tex]x_2[/tex] - [tex]x_1[/tex])
= (2 - 1)/(20 - 0)
= -1/20
= -0.05
The average rate of change over the entire slide is also negative, but it is much smaller than the average rate of change from x = 0 to x = 15.
This is because the slope of the secant line is getting closer to 0 as the interval gets larger.
