let me explain
y=x+1
y= -x + 5
x + 1 = -x +5
GET RID OF X
1 = 5
1 and 5 do not equal each other and there is no x left either so you can’t solve it.
Answer:
No
Step-by-step explanation:
if both equations begin with 'y=' then we can set the expressions equal to each other:
-x+1 = -x+5
1 ≠ 5 ∴ there are no solution to this system of equations

Which statement best compares the spreads of the data sets?
Answers
Answer:
(a) is true
Step-by-step explanation:
Given
See attachment for box plots
Required
Which of the options is true?
Option A compares the IQR of both plots.
IQR is calculated using:
[tex]IQR = Q_3 - Q_1[/tex]
Where
[tex]Q_1 \to[/tex] Lower quartile
[tex]Q_2 \to[/tex] Upper quartile
From the attached plots, we have:
Republican
[tex]Q_1 = 170.5[/tex]
[tex]Q_3 = 356[/tex]
So:
[tex]IQR = 356 - 170.5[/tex]
[tex]IQR = 185.5[/tex]
Democratic
[tex]Q_1 = 181[/tex]
[tex]Q_3 = 367.5[/tex]
So:
[tex]IQR = 367.5 - 181[/tex]
[tex]IQR = 186.5[/tex]
We have:
[tex]IQR = 185.5[/tex] --- Republican
[tex]IQR = 186.5[/tex] --- Democratic
Hence, (a) is true

A rectangular room is 7 times as long as it's wide and it's perimeter is 64metres. Find the dimension of the room.
Answers
Answer:
Length = 28 meters Width = 4 metersStep-by-step explanation:
Assume the width of the rectangle is x. That means that the length of the rectangle is 7x which is 7 times as long as it is wide.
Perimeter of a rectangle:
= Length + length + Width + Width
Therefore:
7x + 7x + x + x = 64
16x = 64
x = 64/16
x = 4 meters
Length is 7 times as long:
= 4 * 7
= 28 meters

Answer:
Team A: 25 players
Team B: 24 players
Step-by-step explanation:
Team A:
to find the total # of players of the team we need to set up a fraction. 5 out out of an unknown number of players is equal to 1/5, so we set it up as:
[tex]\frac{5}{x} = \frac{1}{5}[/tex]
then we cross multiply to get
x*1 = 5*5
x=25 players
Team B
similarly to Team A
[tex]\frac{3}{x} = \frac{1}{8}[/tex]
cross multiply to get
x*1=3*8
x= 24 players

The graph shows the line y= -3x - 6.
Complete the table so it includes two solutions to the equation.
Answers
Answer:
0 | -6
____
3 | -15
Step-by-step explanation:
just plug in the numbers they give u in the chart
when x = 0 -> y = -3*0-6 = -6
when y = -15 -> -15 = -3x-6 -> x = 3
The graph of the line y = -3x -6 is giving the solution (0,-6) and (3,-15).
What is an equation of a line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The given equation of the line is y = -3x - 6. the two points on the graph are satisfying the equation.
x = 0 , y = -3 x 0-6 = -6
y = -15 -> -15 = -3 x-6 -> x = 3
Therefore, the graph of the line y = -3x -6 is giving the solution (0,-6) and (3,-15).

The circus admits children for $2 each and adults for $5 each. How many of each ticket were sold if 160 total tickets were sold for $476? Please I need an answer ASAP
Answers
Answer:
adults = 52
children = 108
Step-by-step explanation:
two equations can be derived from the question
x + y = 160 equation 1
2x + 5y = 476 equation 2
x = number of children
y = number of adults
multiply equation 1 by 2
2x + 2y = 320 equation 3
subtract equation 1 from 2
3y = 156
y =52
substitute for y in equation 1
x + 52 = 108
x = 160 - 52 = 108

A truck delivers 14,000 pounds of gravel.
How many tons are in 14,000 pounds?
Answers
Answer:
7000

Thus the truck delivers 7 tons of gravel.
What is a unit conversion?"A unit conversion expresses the same property as a different unit of measurement. A conversion factor is a ratio that expresses how many of one unit is equal to another unit".
For the above situation,
A truck delivers 14,000 pounds of gravel.
We know that,
1 US ton = 2000 pounds
Thus, 14000 pounds = [tex]\frac{14000}{2000}[/tex]

The radius of the circle X is XY.
Coordinates of X are (0,3) and coordinates of Y are (-3,-1).
To find:
The area of the circle.
Solution:
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The radius of the circle is the distance between the points X(0,3) and Y(-3,-1).
[tex]XY=\sqrt{(-3-0)^2+(-1-3)^2}[/tex]
[tex]XY=\sqrt{(-3)^2+(-4)^2}[/tex]
[tex]XY=\sqrt{9+16}[/tex]
[tex]XY=\sqrt{25}[/tex]
[tex]XY=5[/tex]
The radius of the circle is 5 units.
The area of the circle is:
[tex]A=\pi r^2[/tex]
Where, r is the radius of the circle.
Putting [tex]\pi=3.14, r=5[/tex] in the above formula, we get
[tex]A=(3.14)(5)^2[/tex]
[tex]A=(3.14)(25)[/tex]
[tex]A=78.5[/tex]
