Answer:
x= -5, 2
Step-by-step explanation:
set them equal to each other: [tex]x^{2}+5x-9=2x+1[/tex]
subtract 2x from both sides: [tex]x^{2} +3x-9=1[/tex]
subtract 1 from both sides to make it equal to zero: [tex]x^{2} +3x-10=0[/tex]
find which 2 factors of -10 equal 3: 5 and -2
plug it into: [tex](x +?)[/tex]: [tex](x+5) (x -2)[/tex]
set both equations to zero: [tex]x +5=0[/tex] [tex]x-2=0[/tex]
solve: {x| x=-5, 2}

Create an equation which contains the solution (-1,3)
Answer:
3x + y =0
Step-by-step explanation:
We need to create equation whose solution is (-1,3) . So let another point through which it passes be ( 0,0) .
Since at least two points are required for making a line .Slope :-
=> m = -1-0/3-0
=> m = -1/3
Using point slope form :-
=> ( x - x1) = m( y - y1)
=> ( x - (-1)) = -1/3( y - 3)
=> (x + 1 )3= -y + 3
=> 3x +3 = -y + 3
=> 3x + y = 0
✔️ Checking :-
(-1,3)=> 3(-1) + 3 = 0
=> -3+3=0
=> 0 = 0
• Hence the equation can be 3x + y = 0 .
Explain how to find the volume of the four ice cubes in the glass below if each ice cube is 2 inches wide. Pls help
The total volume of the ice cubes is 32 in^3
We know that, for a cube of side length L, the volume is:
V = L^3
So if we know that each of the ice cubes is 2 inches wide, we can see that the side length of each ice cube is 2 inches.
Then we have L = 2in
Then the volume of each ice cube is:
V = (2in)^3 = 8 in^3
And we have four of these, then the total volume is 4 times the volume of a single ice cube.
Total volume = 4*( 8 in^3) = 32 in^3

7. Murray spins the pointer of the spinner shown at the right
a. What is the sample space for the probability model?
b. What is the probability of each event in the sample space?
Answer:
a)
Sample Space of Probability model is - S' = { [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] }
b)
Probability of Event 1 , P(1) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]
Probability of Event 2 , P(2) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]
Probability of Event 3 , P(3) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]
Probability of Event 4 , P(4) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]
Step-by-step explanation:
Given - Murray spins the pointer of the spinner as shown .
To find - a. What is the sample space for the probability model?
b. What is the probability of each event in the sample space?
Proof -
The Sample space is the set of all possible outcomes.
So,
Sample space becomes -
S = { 3, 5, A, Y, 3, 5, A, Y}
Total number of outcomes, n(S) = 8
Now,
We can see that There are 4 types of event
Event 1 : 3
Event 2 : 5
Event 3 : A
Event 4 : Y
So,
Probability of Event 1 , P(1) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]
Probability of Event 2 , P(2) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]
Probability of Event 3 , P(3) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]
Probability of Event 4 , P(4) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]
Now,
Sample Space of Probability model is -
S' = { [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] }
∴ we get
a)
Sample Space of Probability model is - S' = { [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] , [tex]\frac{1}{4}[/tex] }
b)
Probability of Event 1 , P(1) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]
Probability of Event 2 , P(2) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]
Probability of Event 3 , P(3) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]
Probability of Event 4 , P(4) = [tex]\frac{2}{8} = \frac{1}{4}[/tex]

What is the length of the line?
Choose 1 answer:
Answer:
√29
Step-by-step explanation:
We can use the pythagorean theorem to find the length of this line. You can draw a vertical line downwards from the higher point and a horizontal line towards the left from the lower point. This will create a right triangle. Wd can count the lengths of the legs, getting 2 and 5. We can substitute these values in the pythagorean theorem:
a^2 + b^2 = c^2
2^2 + 5^2 = c^2
4 + 25 = c^2
c^2 = 29
c = √29
Since c is the hypotenuse and is the same length of the line, the line is √29 units long

The graph of a linear equation passes through the points (-4,1) and (4,6)
HELP!
Answer:
a) (0, 3.5)
b) (12, 11)
Step-by-step explanation:
The points through which the graph of the linear equation passes are;
(-4, 1) and (4, 6)
The slope of the equation of a straight line passing through points (x₁, y₁), and (x₂, y₂), 'm', is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
∴ The slope of the equation, m = (6 - 1)/(4 - (-4)) = 5/8 = 0.625
The equation of th line in point and slope form is therefore;
y - 1 = 0.625·(x - (-4))
∴ y = 0.625·(x - (-4)) + 1 = 0.625·x + 3.5
y = 0.625·x + 3.5
Therefore;
a) When x = 0, y = 0.625 × 0 + 3.5 = 3.5
∴ The point (0, 3.5) is a solution
b) When x = 12, we have, y = 0.625 × 12 + 3.5 = 11
∴ The point (12, 11) is a solution
However;
c) When x = 8, we have, y = 0.625 × 8 + 3.5 = 8.5
∴ The point (8, 5) is not a solution
d) When x = -6, we have, y = 0.625 × (-6) + 3.5 = -0.25
∴ The point (-6, 0) is not a solution
Therefore;
The points which are solutions are;
(0, 3.5) and (12, 11)
What is the equation of the line that is perpendicular to the line y=3/4x - 6 and passes through the point (-3,5)?
Answer:
[tex]y=-\frac{4}{3}x+1[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Perpendicular lines always have slopes that are negative reciprocals of each other (ex. -1/3 and 3, 1/2 and -2, etc.)1) Determine the slope (m)
[tex]y=\frac{3}{4} x - 6[/tex]
Looking at the given equation, we can identify clearly that [tex]\frac{3}{4}[/tex] is in the place of m, making it the slope of the line. Because perpendicular lines always have slopes that are negative reciprocals, we know that the slope of the line we're solving for will be [tex]-\frac{4}{3}[/tex]. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-\frac{4}{3}x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=-\frac{4}{3}x+b[/tex]
Plug in the given point (-3,5)
[tex]5=-\frac{4}{3}(-3)+b\\5=4+b[/tex]
Subtract 4 from both sides
[tex]5-4=4+b-4\\1=b[/tex]
Therefore, the y-intercept is 1. Plug this back into [tex]y=-\frac{4}{3}x+b[/tex]:
[tex]y=-\frac{4}{3}x+1[/tex]

Jorge works at a dairy farm that ships eggs to restaurants. Jorge decides to try new packaging for the eggs to see if it results in fewer broken eggs. Jorge packs a random sample of 8 shipments with the current packaging and a random sample of 8 shipments with the new packaging. He collects data from the restaurants on the number of broken eggs in each shipment. Current packaging: 5, 9, 4, 4, 5, 5, 7, 4 New packaging: 3, 6, 6, 3, 5, 5, 6, 5 The means are 5.375 and 4.875 respectively, for a difference of 0.5. Jorge wants to know if this is significant or if it could be caused by chance. To find out, he re-randomizes the results 12 times and finds the differences of the means. The dot plot shows the data. What is the best conclusion for Jorge to make based on the data
Answer:
The difference of 0.5 is not significant because the re-randomizations show that it is within the range of what could happen by chance.
Step-by-step explanation:
For the means which are given as 5.375 and 4.875 respectively, for a difference of 0.5.
