Suppose that you decide to participate in a charity walkathon to raise money for your cause. Some people decide to donate a fixed amount, while others agree to donate a little money for every mile you walk. Before the event starts, you raised $25, and you have been pledged $1.50 for each mile you walk. The function defined by d(m)=1.5m+25 can be used to relate the miles you walk, m, and the amount of money donated to you in dollars, d(m).
Evaluate d(3).
Answer:
Step-by-step explanation:
d(3)=1.5x3+25=29.5
Which of the following is a zero for the function f(x) = (x + 3)(x - 7)(x + 5)
O x= -7
x = -3
x = 3
x = 5
Answer:
-3, 7, -5
Step-by-step explanation:
The x intercept is when y equals zero, so plug in numbers that would make y equal 0.
In this case, if anything inside the brackets is 0 then the whole think would be 0.
any number times 0 is 0.

How often does the line y = 1 intersect the graph?
three times
does not intersect
once
twice
Answer:
3 times
Step-by-step explanation:
Take out a ruler and draw a horizontal line through y = 1. It should become obvious immediately that this horizontal line intersects the graph 3 times.
The line [tex]\boldsymbol{y=1}[/tex] intersect the graph three times.
GraphA graph is a mathematical depiction of a network that describes the connection between lines and points.
A graph is made up of points with lines connecting them. The length of the lines and the position of the points are irrelevant. Each object in a graph is referred to as a node.
Line [tex]\boldsymbol{y=1}[/tex] intersects the graph at three points.
So, the line [tex]y=1[/tex] intersect the graph three times.

Grace is going to a carnival that has games and rides. Each game costs $1.50 and each ride costs $2.50. Grace spent $16.50 altogether at the carnival and the number of games she played is twice the number of rides she went on. Write a system of equations that could be used to determine the number of games Grace played and the number of rides Grace went on.
Answer:
Number of Rides: [tex]5.5R = 16.5[/tex]
Number of Games: [tex]1.5G = 9[/tex]
Step-by-step explanation:
Given
Represent the games with G and the Rides with R
[tex]G = 1.50[/tex] -- cost
[tex]R = 2.50[/tex] --- cost
[tex]Total = 16.50[/tex] -- cost
Required
Represent the system using an equation
The equation can be represented as follows;
[tex]G + R = Total[/tex]
Assume She plays G games and had R rides, we have
[tex]1.5G + 2.5R = 16.5[/tex]
Since she plays twice as much games as rides,
This implies;
[tex]G = 2R[/tex]
So, we have
[tex]1.5 * 2R + 2.5R = 16.5[/tex]
[tex]3R + 2.5R = 16.5[/tex]
[tex]5.5R = 16.5[/tex] --- This equation can be used to solve for Number of Rides
Solving further
[tex]R =16.5/5.5[/tex]
[tex]R =3[/tex]
Substitute 3 for R in [tex]1.5G + 2.5R = 16.5[/tex]
[tex]1.5G + 2.5 * 3 = 16.5[/tex]
[tex]1.5G + 7.5 = 16.5[/tex]
Solve for 1.5G
[tex]1.5G = 16.5 - 7.5[/tex]
[tex]1.5G = 9[/tex] --- This equation can be used to solve for Number of Games
Solving further
[tex]G = 9/1.5[/tex]
[tex]G = 6[/tex]

Part A.
bh + hr = 25
h( b + r ) = 25
h = 25/ b + r
Part B
hr = 25 - bh
r = (25 - bh)/h
r = 25/h - b
2.
Part A.
xy = r - h
-h = -r + xy
divide both sides by -1
h = r - xy
Part B
xy = r - h
xy + h = r

24. Predict the type of quadrilateral that is formed
by the points of intersection of the lines
3x + y - 4 = 0, 4x - 5y + 30 = 0,
y = – 3x – 1, and - 4x + 5y + 10 = 0. Give
reasons for your prediction. Verify that your
prediction is correct by solving this problem.
Answer:
A PARALLELOGRAM OR A RHOMBUSStep-by-step explanation:
Given the equation of the lines 3x + y - 4 = 0, 4x - 5y + 30 = 0, y = – 3x – 1, and - 4x + 5y + 10 = 0. For us to be able to predict the type of quadrilateral formed by this lines, we need to find the slope of each of the lines. Any two lines with the same slope will be parallel lines.
The standard form of equation of a line is expressed as y = mx+c where m is the slope of the line.
Re-writing each equation in standard format:
For the line 3x + y - 4 = 0;
3x+y = 4
y = 4-3x
y = -3x + 4
Hence the slope of the line is -3
For the line 4x - 5y + 30 = 0:
4x-5y = -30
-5y = -30-4x
-5y = -4x-30
divide through by -5
y = 4/5 x + 6
Hence the slope of this line is 4/5
For the line y = – 3x – 1:
The line is already in its standard format, hence the slope of the line is -3
For the line - 4x + 5y + 10 = 0:
-4x+5y = -10
5y = -10+4x
5y = 4x-10
divide through by 5
y = 4/5 x - 10/5
y = 4/5 x - 2
Hence the slope of this line is 4/5
From the slopes above, it can be seen that the line 4x - 5y + 30 = 0 is parallel to - 4x + 5y + 10 = 0 and that of the line 3x + y - 4 = 0 is parallel to y = – 3x – 1 due to their similar slope.
To know the the type of quadrilateral formed by this lines, first we need to check whether two dissimilar lines are perpendicular to each other. If they are perpendicular to each other, it means the quadrilateral could be a square or a rectangle but if otherwise, it will either be a parallelogram or a rhombus.
For two lines to be perpendicular, the product of their slope must be -1 i.e m1m2 = -1
For the first two lines:
m1 = -3 and m2 = 4/5
Taking their product:
-3*4/5 = -12/5
Since the product did not give use -1, hence the quadrilateral is neither a square nor a rectangle. The quadrilateral can therefore either be a parallelogram or a rhombus since the intersecting lines of either shapes are not perpendicular to each other.
Chris can be paid in one of two ways. Plan A is a salary of $490 per month, plus a commission of 9% of sales. Plan B is a salary of $826 per month, plus a commission of 3% of sales. For what amount of sales is Chris better off selecting plan A?
Step-by-step explanation:
Explanation:
First, when dealing with percents, "Percent" or "%" means "out of 100" or "per 100", Therefore x% can be written as
x/100.
The expression for Plan A can be written as:
490+(9/100)s where s is the sales for the month.
The expression for Plan B can be written as:
826+(3/100)s
The question we are being asked is when is Plan A > Plan B. So, we can write and solve this inequality:
490+(9/100)s>826+(3/100)s
490+(9/100)s−490−(3/100)s>826+(3/100)s−490−(3/100)s
490−490+(9/100)s−(3/100)s>826−490+(3/100)s−(3/100)s
0+(9/100)s−(3/100)s>826−490+0
(9/100)s−(3/100)s>826−490
(9/100−3/100)s>336
(6/100)s>336
(100/6)×(6/100)s>(100/6)×336
s> 33600/6
s>5,600
Plan A is better when sales for the month are greater than $5,600.

An automobile with a mass of 1200 kg accelerates at a rate of 3.0 m/s2 in the forward direction. What is the net force acting on the automobile?
The net force acting on the automobile is 3600N
The acceleration of an object is directly proportional to the net force acting on it.
The acceleration of an object also depends upon its mass.
Acceleration (a) = net force (F) / mass (m)
a = F / m
Given that; a = 3 m/s², m = 1200 kg, hence:
3 = F / 1200
F = 3600N
The net force acting on the automobile is 3600N

how do u do this ??????
Answer:
the answer is 50 degrees
Step-by-step explanation:
the sum of all three angles of a triangle is always 180 degrees.
first you have to combine all terms, equal it to 180, and then solve for x.
4x-20+2x+2x=180
8x-20=180
8x=200
x=25
then to find angle G you multiple x times 2 (2x)
