Drag and drop each pair of lines into the correct category to indicate whether the pair of lines are parallel, perpendicular, or neither.
Answer:
Step-by-step explanation:
to know:
-to be paralel the lines have to have the same slope
-to be perpendicular the slope has to be negative invers of thhe other
-to be neither has to be none of the above two
equation to compare to is
y=mx+b where m is the slope
if your equation does not have this form make it have this form
2y=3x+1 so divide by 2
y=[tex]\frac{3}{2}[/tex] x+1 so here the slope is [tex]\frac{3}{2}[/tex]
4x+6y=14 so subtract 4x and then divide by 6 to isolate y
6y= -4x+14
y=[tex]\frac{-4}{6}[/tex] x + [tex]\frac{14}{6}[/tex] symplify
y=[tex]\frac{-2}{3}[/tex] x + [tex]\frac{7}{3}[/tex] so the slope here is [tex]\frac{-2}{3}[/tex]
So if you compare the slopes you can see that are negative reciprocal of eachother so the lines are perpendicular
and so on...

It takes 12 people to mow Richard Richerson's lawn. If his lawn is 600,000 square yards, what is the average number of square yards each person will mow?
Answer:
each person will mow 50,000 square yards
Step-by-step explanation:
Given;
mow Richard Richerson's lawn = 600,000 square yards
number of people, = 12 people
The average number of square yards each person will mow is given by;
= 600,000 square yards / 12 people
= 50,000 square yards / person
Therefore, each person will mow 50,000 square yards

Step-by-step explanation:
[tex] m\angle AED = 79\degree \\ .... (given) \\\\

1a. A club has 11 members. How many different 3-member committees could the club form?
a) 165
OR
b) 990
1b. in how many ways a club president can a club president, treasurer and secretary be chosen?
a) 165
OR
b) 990
Answer:
1a is 165
1b is 990
Step-by-step explanation:
So the first one is basically asking the possibility of each member being chosen for one of each role.
While the second one is asking the possibility of the person being in one specific role and making that be considered a possibility.
In other words, it's basically easier to get into one of the three roles rather than being in one specific role.

A rope is 225 centimeters long.
You need the rope to be 1 1/2 meters long.
How many centimeters should you cut off?
Rope = 225 cm
Needed rope = 11/2m = (11/2) × 100 cm = 550cm
So, rope needed to be cut
= 550cm - 225cm
= 225cm
=225/100m
=2.25 m

Answer:
1/3 or 0.3
Step-by-step explanation:
5/8 x 4/5 x 2/3 =
1/3 or 0.3
Answer:
1/3 in^3
Step-by-step explanation:
In order to find the volume, you must multiply the length, by the width, by the height. This would mean you need to do 2/3x5/8x4/5=40/120
40/120 simplified will give you 1/3
the answer would be (12)

Solve the following system of equations graphically on the set of axes below. y=3x−3 , x+y=5
Answer:
x=2, y=3
Step-by-step explanation:
First, graph both equations on a rectangular coordinate system (see attached screenshot). Then, simply figure out where these two lines intersect. Since they intersect at (2,3), x=2 and y=3.
Plugging these values in the equations for x and y, you can see if these are the correct answers:
(3)=3(2)-3, (2)+(3)=5
Since both of these are true, you have the right answer.
Hope this helps!
Two linear equation has their solutions on the points where they intersect each other.
The solution of the given system of equations is:
x = 2, y = 3.
How to determine the solution of system of linear equations graphically?Each linear equation represents a straight line.
If both the given lines intersect at one point, then that point's coordinate is the solution of the given system of the equations.
If both the given lines are parallel, then there is no intersection and thus no solution.
If both the lines are coincident(that is, lying over each other fully), then there are infinite points of intersection, as they touch each other on infinite points, and thus infinite solutions to the given system of equations exist.
Using method of substitution to solve the system of equations:[tex]y = 3x-3\\ x+y = 5 [/tex]
Substituting the value of y from first equation in the second equation, we get:
[tex]x + y = 5\\ x + (3x-3) = 5\\ x+3x = 5+3\\ 4x = 8 \\ x = 2\\ [/tex]
Thus, putting this value of x in first equation, we get:
[tex]y = 3x - 3\\ y = 3 \times 2 - 3\\ y = 6-3\\ y = 3[/tex]
Thus, the system has one solution and it is x = 2, y = 3.
Using graphing, we can see that point of intersection is (x,y) = (2,3)

Two trapezoids below are similar what is the length of RS?
9514 1404 393
Answer:
11.5 m
Step-by-step explanation:
The fact that the figures are similar means the side lengths are proportional:
RS/QT = BC/AD
RS/(7 m) = (2.3 m)/(1.4 m)
RS = (7 m)(2.3/1.4) . . . . . . multiply by 7 m
RS = 11.5 m

Reggie plans to have a garden with 36 plants. He wants the ratio of tomato plants to cucumber plants to be 4:5. How many cucumber plants will be in Reggie's garden?
Answer:
20
Step-by-step explanation:
Total no of plants in a garden = 36
The ratio of tomato plants to cucumber plants to be 4:5.
Let tomato plants are 4x and cucumber plants is 5x.
ATQ,
4x+5x=36
9x = 36
x = 4
For cucumber plant, 5x = 5(4) = 20
So, there are 20 cucumber plants will be in Reggie's garden
(180-x)+(90-x) = 124
Answer:
x = 73
General Formulas and Concepts:
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Define equation
(180 - x) + (90 - x) = 124
Step 2: Solve for x
Combine like terms: 270 - 2x = 124Subtract 270 on both sides: -2x = -146Divide -2 on both sides: x = 73Step 3: Check
Plug in x to verify it's a solution.
Substitute: (180 - 73) + (90 - 73) = 124Subtract: 107 + 17 = 124Add: 124 = 124what is the equation of the line with slope -3 and y-intercept 6? Express your answer in slope-intercept form.
Answer:

Answer:
y = -3x + 6
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
SO
m = -3
b = 6
Thus,
y = -3x + 6
