Answer:
x = -2
Step-by-step explanation:
( 2x - 1 ) ( x + 3 ) - ( x + 3 ) ( x - 3 ) = x + 2
Expand
x^2 + 5x + 6 = x + 2
x^2 + 5x + 6 - 2 = x + 2 - 2
x^2 + 5x +4 = x
x^2 + 5x + 4 - x = x - x
x^2 + 5x + 4 = 0
-4 / 2 = -2
x = -2

Step-by-step explanation:
(3,1) m=2
show werek
[tex]\\ \sf\longmapsto y=mx+b[/tex]
[tex]\\ \sf\longmapsto 1=2(3)+b[/tex]
[tex]\\ \sf\longmapsto 1=6+b[/tex]
[tex]\\ \sf\longmapsto b=-5[/tex]
Equation of the line:-
[tex]\\ \sf\longmapsto y=2x-5[/tex]
Answer:
y = 2x - 5
Step-by-step explanation:
Assuming you require the equation of the line
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (3, 1 ) into the partial equation
1 = 6 + c ⇒ c = 1 - 6 = - 5
y = 2x - 5 ← equation of line

Liam knows the key to making creamy risotto, a rice dish, is to add the liquid to the rice gradually. He adds 5 ladles of chicken broth to his rice before adding seasoning, and he continues to add 2 ladles of broth each minute afterwards.Write an equation that shows the relationship between the number of minutes since Liam added the seasoning, x, and the total number of ladles of broth he has added, y.
The equation that shows the relationship between the number of minutes and total number of ladles of broth is y = 2x + 5
Let x represent the number of minutes and y represent the total number of ladies.
Since he adds 2 ladles of broth each minute and he has 5 ladies initially, hence:
y = 2x + 5
The equation that shows the relationship between the number of minutes and total number of ladles of broth is y = 2x + 5

Jon is training for a bike race and is attempting to improve his average speed. With his old trainer, Jon averaged a pace of 20 MPH. With his new trainer, he rode at an average speed of 22 MPH. By what percent did his average speed increase?
Answer:
Jon is now 10% faster.
Step-by-step explanation:
Since Jon's average speed was 20 MPH and his new average speed is now 22 MPH, we can see that his speed increased by 2 MPH. Now we know that, we would now do 2÷20 = .1
10% is the percent form of 0.1

this is because you do 250 - 100 which equals -150
In part A you subtracted 100 from 100 giving you 0.
Continuing to part B you would subtract 100 from 250 leaving you with 150.

While on vacation in Washington DC, the cab ride for the Dulles airport to the hotel is 15 miles. The
total cost of the cab ride was $25.50. The cabbie charges $1.50 per mile for the entire trip.
A. Write an equation to that can be used to determine how much a cab ride would cost anywhere in Washington DC.
B. What is the flat rate of the cab ride?
C. How much does it cost to travel 7 miles in a cab?
The equation that can be used to determine the cost of a cab ride is cost = $3 + ($1.50 x miles driven).
The flat rate of the cab ride is $3.
The cost of travelling 7 miles is $13.50.
The total amount that would be spent on the cab ride is a function of the price per mile, the total miles driven and the flat rate.
Total cost = variable rate + flat rate
variable rate = cost per mile x total miles driven
15 x $1.50 = $22.50
Flat rate = total cost - variable rate
$25.50 - $22,50 = $3
The equation to determine the total cost of a cab ride: $3 + $1.50m
Where m is the miles driven.
The cost of travelling 7 miles : 3 + (1.5 x 7) = $13.50

Step-by-step explanation:
True option is, B. AP+PM=AM.
What is a straight line?A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.
Here, given that, point P is between A and M,
Then, A & M are the endpoints & P is on the line.
A---------------------P--------------------M
So, we get, AP+PM= AM
Hence, True option is, B. AP+PM=AM.

In the given figure, no pair of opposite sides are parallel.
There are no parallel side in the given figure.
Given is a figure we need to determine if there are any parallel side or not,
So, the parallel sides are defined as =
When two or more sides of a polygon are described as parallel, it means that they never cross over and are always equally spaced apart.
In other words, these sides would never intersect or cross each other if you extended them endlessly.
Shapes like squares, parallelograms, rectangles, and trapezoids are frequently linked to the idea of parallel sides.
The opposing sides of these polygons are parallel to one another. For instance, just one pair of opposite sides in a trapezoid is parallel but both sets of opposite sides are parallel in a rectangle.
So according to the definition of parallel lines there are no parallel sides in the figure.

A project calls for three pieces of wood. The longest piece must be twice the length
of the middle-sized piece. The shortest piece must be 10 in. shorter than the middle-
sized piece. If a board 70 in. long is to be used, how long can each piece be?
Answer:
70,35,25
Step-by-step explanation:
Let longest piece = a = 70
Let medium piece = b = 35
Let shortest piece = c = 25
a=2b
70=2b
35=b
c+10=b
c+10=35
c=25

Fractions are integers that have both a numerator and a denominator. They are represented as; [tex]\frac{x}{y}[/tex]
Where:
x = Numerator
y = Denominator.
To solve the above question, we would be applying the operations of the addition of fractions.
It will take both of them [tex]27\frac{3}{11}[/tex] hours if they worked together.
From the question,
Nyesha takes 50 hours a week to render services to her customers.
Shantese takes 60 hours a week to do the same amount of work.
Let us represent the number of hours it will take them both to decorate the room working together as "T"
Hence,
1/T = 1/50 + 1/60
Lowest Common Denominator for (50, 60 ) = 300
Hence,
1/T = 6 + 5 / 300
1/T = 11/300
Find the reciprocal of both sides
T = 300/11 hours
T = [tex]27\frac{3}{11}[/tex] hours
Therefore, it will take them both of them [tex]27\frac{3}{11}[/tex] hours in they both work together.

TOMATO: I chose the tomato (because the numbers are round and easy to manipulate) The target is 60ft away, so the maximum height of the launch has to be 45 feet.
PUMPKIN: I chose the pumpkin. The target is 50 ft away, so the maximum height is 62 feet.
