Answer:
Average rate of change is -7/3 and the initial value is 24
Step-by-step explanation:
The rate of change is simply the slope of the line connecting the points
mathematically, that would be;
m = y2-y1/x2-x1
m = (10-3)/(6-9) = -7/3
Let us get the complete equation;
The general equation form is;
y = mx + b
where m is slope and b is y-intercept
y = -7x/3 + b
To get b, we simply insert one of the points
Let us use (9,3)
We insert x = 9 and y = 3
So we have;
3 = -21 + b
b = 3 + 21
b = 24
So the complete equation is;
y = -7x/3 + 24
The initial value is when x = 0
If x = 0, y will be 24

Stan ran 4 and StartFraction 7 Over 10 EndFraction miles, which was 1 and StartFraction 3 Over 10 EndFraction fewer miles than Matt ran. Four students wrote and solved equations to find m, the number of miles that Matt ran. Which student wrote and solved the equation correctly?
Answer:
6 miles
Step-by-step explanation:
From the above question:
Stan ran 4 and StartFraction 7 Over 10 EndFraction miles
The number of miles stan ran =
4 7/10 miles
We are also told that this number of miles was 1 and StartFraction 3 Over 10 EndFraction fewer miles than Matt ran.
Let the number of miles Matt ran = m
Hence,
4 7/10 miles = m - 1 3/10
m = 4 7/10 + 1 3/10
m = (4 + 1) + ( 7/10 + 3/10)
m = 5 + (7 + 3/10)
m = 5 + (10/10)
m = 5 + 1
m = 6 miles
Therefore, the number rod miles Matt ran was 6 miles

I need help. I finished questions 9 and 10. Now I need help with 11 and 12.
Answer:
Question 9) [tex]y=\frac{-3}{2}x+2 \\\\[/tex]
Question 10) [tex]y=-x-6\\[/tex]
Step-by-step explanation:
Well there are two methods of determining an equation of line
Method 1 (Using the slope-intercept form):
[tex]y=mx+b[/tex]
This method is mostly used when the y-intercept also known as b is given and the slope also known as m is given
Method 2 (Using the point-slope form):
[tex]y-y_1=m(x-x_1)\\[/tex]
This method is used when a point is given also known as (x1 , y1) and the slope is given which is denoted by m.
Since in Question 9 there is no y-intercept given only two points we will use the second method so here goes,
Q9)
Two points are (0 , 2) and (4 , -4) first step to find out the equation of line is to calculate the slope which is as follows:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-4-2}{4-0} \\\\m=\frac{-6}{4}\\\\m=-3/2 \\[/tex]
Now we have our slope which is m = -3/2 now since we have two points we can use any point in the point-slope form equation because both of these points lie on the line hence satisfying the desired equation that we need so we select the point (0 , 2) [YOU CAN TRY OUT FINDING THE EQUATION OF LINE BY USING THE OTHER POINT THE ANSWERS WOULD BE SAME]
so now we have the point (0 , 2) and value of m = -3/2
[tex]y-y_1=m(x-x_1)\\y-2=\frac{-3}{2}(x-0)\\\\y-2=\frac{-3}{2}x\\\\y=\frac{-3}{2}x+2\\\\[/tex]
Question 10)
Two points are (-2 , -4) and (-3 , -3) we use the same method as shown above,
First step calculate the slope:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-3-(-4)}{-3-(-2)} \\\\m=\frac{-3+4}{-3+2}\\\\m=1/-1\\\\m=-1\\[/tex]
now we insert the value of m = -1 and take any point of the two points that are given, we select the first point (-2 , -4)
[tex]y-y_1=m(x-x_1)\\y-(-4)=(-1)(x-(-2))\\y+4=(-1)(x+2)\\y+4=-x-2\\y=-x-2-4\\y=-x-6\\[/tex]

In order, top to bottom:
(-3,6)
(-2,1)
(0,-3)
(2,1)
(3,6)
Step-by-step explanation:
All you have to do is plug the X given into the equation provided to find Y, y=x^2-3.
For the first row, you're given -3 for X, so you plug that into the equation.
y=(-3)^2-3 So, -3^2 is just (-3) times (-3) which equals 9. Then you subtract 3 from 9 which gives you 6. So your Y=6 for the first row. And, you do the same thing for the rest of the rows. Just plug X in and solve. Anything raised to the second power is just that number multiplied by itself like I did with the -3.

What is the value of x? ( BRAINLY FOR WHOEVER )
Answer:
-6
Step-by-step explanation:
I hope this helps you out!
Answer:
x = 22
Step-by-step explanation:
Okay since they give you the measurement of 96 degrees and the lines are parallel, this means that 6x - 36 equals 96 degrees. However we are trying to find out what the variable x equals so we are going to put 6x - 36 and 96 degrees into a equation:
6x - 36 = 96
Now we are going to get all variables on one side of the equal sign and all numbers on the other, starting with adding 36 to both sides of the equal sign.
6x - 36 = 96
+ 36 +36
So now the equation looks like this:
6x = 132
Now we are going to segregate the variable x from 6x by dividing 6x by 6 and what you do to one side of the equal sign you do to the other:
6x/6 = 132/6
to equal:
x = 22
Now to check our work we are going to replace the variable x with 22 into the equation:
6x - 36 = 96 Now 6(22) - 36 = 96
132 - 36 = 96
96 = 96
I hope this helps you!!

Francis can buy 7 shirts for $42 or 8 shirts for $48. How much will she pay for nine?
Answer:
$54
Step-by-step explanation:
[tex]42/7=6\\48/8=6\\x/9=6\\x=54[/tex]
Hope this helped :D
Answer: $54
Step-by-step explanation:
if we divide 42 by 7, or we divide 48 by 8, we can see that it is 6. so, one shirt costs $6. then, we just multiply 9 (the amount of shirts) by 6 (the cost of a shirt), and we get 54.

Study the statements carefully.
12/3 = 4 because 12 = 4•3
6/0 = x because 6 = x•0
What value can be used in place of x to create true statements? Explain your
reasoning
Answer
x = unidentified
Explanation
If 12÷3=4 and 12 = 4×3, that means 6÷0=x and x×0=6.
This isn't possible because any number divided by 0 is unidentified.
Ali was swimming along the bottom of his backyard pool at a depth of 6 feet then he pushed off the bottom and rose 4 feet what is ali's position now relative to the surface of the pool .To solve the problem ,fatima made this equation _6+4 and came up with an answe of 2 feet
Answer:
2 feet.
Step-by-step explanation:
Here the surface of the water is taken as the reference point. Let us take the depth of the swimmer below the water to be negative. Ali is 6 feet from the surface of the water so his height is -6. He then rose 4 feet so this need to be added to his initial height.
So, Ali has reached a height of [tex]-6+4=-2\ \text{feet}[/tex]. Hence, Ali is 2 feet from the surface of the water.

Analyze the graph. Which inequality represents the graph?
y > -1/3x + 4
y –3x + 4
y < –3x + 4
Answer:
y < -3x + 4
Step-by-step explanation:
From the graph, we can see that the intercept on the y axis is 4 while the intercept on the x-axis is approximately 1.33 or simply 4/3.
This means, at x = 0, y = 4 and at y = 0, x = 4/3.
Therefore the linear equation is;
y = -3x + 4
However, the shaded area is below the line and so the operation will be with the sign less than(<). Also, we see that the line is broken and this means that the line doesn't include equal to "=" sign.
Thus, the correct inequality is;
y < -3x + 4
