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.

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

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)
2 × 25 = 50
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]

A lion runs 45 mph and crosses a bridge in 40 seconds. A cheetah runs across the same bridge in 30 seconds. How fast does the cheetah run?
Answer:
60 mph because the cheetah runs at 4/3 of the lion's pace, which is 45 mph. 4/3 x 45 is 60.
The cheetah's speed is 60 mph
Average speed is total distance ran per time
Average speed = total distance / time
We are to determine the average speed of the cheetah. The average speed cannot be determined because the distance ran by the cheetah is not provided. The distance has to be determined
Information on the distance run can be determined from the information of the lion provided
45 = total distance ÷ 40
total distance = 45 x 40
total distance = 1800
Average speed of the cheetah = 1800 ÷ 30
= 60 mph

Question
Cable company A charges $45 a month for cable plus a $18 installation fee. Cable B charges $39 a month for cable plus a $30 fee for installation. Which inequality can be used to find out when the monthly cost for Cable company A is less than Cable company B?
a)39x+30<45x+18
b) 45x+18>39x+30
c) 45x+18<39x+30
d)39x+18<45x+30
Answer:
c) 45x+18<39x+30
Step-by-step explanation:
Step 1
We have to find the Algebraic expressions for the cable companies
Cable company A charges $45 a month for cable plus a $18 installation fee.
Let the number of months be represented as x
Hence, this is represented as:
$45 × x + $18
= 45x + 18
Cable B charges $39 a month for cable plus a $30 fee for installation.
Let the number of months be represented as x
Hence, this is represented as:
$39 × x + $30
= 39x + 30
The inequality that can be used to find out when the monthly cost for Cable company A is less than Cable company B?
= Cable company A < Cable company B
= 45x + 18 < 39x + 30
Therefore option c is correct
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.

Find an equation perpendicular to x=1 and passing through (8,-9)
What is the equation (Type your answer in standard form.)
Answer:
[tex]y=-9[/tex]
Step-by-step explanation:
We want to find an equation of a line that's perpendicular to x=1 that also passes through the point (8,-9).
Note that x=1 is a vertical line since x is 1 no matter what y is.
This means that if our new line is perpendicular to the old, then it must be a horizontal line.
So, since we have a horizontal line, then our equation must be our y-value of our point.
Our y-coordinate of our point (8,-9) is -9.
Therefore, our equation is:
[tex]y=-9[/tex]
And this is in standard form.
