Step-by-step explanation:
x^2^2 - 9x^2 + 1x^2 - 9
= x^2(x^2 - 9) + 1(x^2 - 9)
= (x^2 + 1)(x^2 - 9)
= (x^2 + 1)(x-3)(x+3) <- (This is due to the a^2-b^2 theorem)

m= slope
b = y-intercept (The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.)
To start with, you’ll need two ordered pairs (x,y) from the line to solve for slope.
For the first graph:
Let (x1,y1) = (0,2)
(x2,y2) = (2,4)
Substitute these values into the slope formula:
m = (y2 - y1)/(x2 - x1)
m = (4 - 2)/(2 - 0)
m = 2/2 = 1
Therefore, the slope (m) = 1.
Next, for the y-intercept, the point where it crosses the y-axis is at point (0, 2). Therefore, the y-intercept (b) = 2.
Thus, the linear equation of the first graph in slope-intercept form is: y = x + 2.
For the 2nd graph, do the same steps as we have done in the 1st graph:
Choose 2 ordered pairs:
Let (x1,y1) = (0,2) — right off the bat, this is the y-intercept.
(x2,y2) = (2,0)
Substitute these values into the slope formula:
m = (y2 - y1)/(x2 - x1)
m = (0 - 2)/(2 - 0)
m = -2/2 = -1
Therefore, the slope (m) = 1.
For the y-intercept, I noted earlier that (0,2) is the y-intercept. Hence, b = 2.
The linear equation in slope-intercept form of the 2nd graph is: y = -x + 2

The total number of person in the sport center is given as 130
We have 130 - 123 = 7
This means that there are a total of 7 persons that do not make use of this facility.
Hence the probability of a person not using the facility is 7/130

This week he worked for 9 1/2 hours.
Work out John's total pay for this week.
Answers
Step-by-step explanation:
Given,
John get paid for working per hour = £6.80
he worked this week = 9 1/2 hr can be written as 19/2 hr.
so, total amount he will get paid for working 19/2 hr
= 19/2 × 6.80
= 19 × 3.40 = 64.60 or 64.6
therefore, John's total.pay of this week is £64.6.
hope this answer helps you dear...take care and may u have a great day ahead!
Explanation
convert 9 1/2 to a decimal
9.5 which is the hours he worked
then multiply his pay £6.80 by his hours worked 9.5

Explanation:
The mean is the average of a data set; it is the number that falls directly in the middle of the data set.
The formula to find the average is: a=sum of terms/ number of terms.
Therefore, we just add up all the values in the data set and divide by how many numbers there are.
3+9+10+10+4+10+10+10/8 = 8.25. We added up all the numbers and then divided by how many numbers there were, which was 8.
8.25 rounded to the nearest tenth is 8.3.
Your answer is 8.3

PLEASE HELP ME ASAP.
Answers
Step-by-step explanation:
anything whole or complete is designated as 100%.
what is x% of that whole ?
well, we need to multiply the whole with the same factor we need to multiply 100 with to get x.
100×f = x
f = x/100
whole × f = x% of the whole
so, when we are looking for 5%, what did that mean ?
it means that x = 5, and f = 5/100.
therefore, 5% of $13 is
13 × 5/100 = 65/100 = 0.65
so,
basic cost = $13
tax rate = 5%
tax amount = $0.65
and
basic cost = $13
tax amount = $0.65
total cost = 13 + 0.65 = $13.65
as 5/100 = 0.05
we have seen that the tax amount is simply $13×0.05
and when we add the tax amount to the basic cost, we need to add $13×1 (basic cost) to the $13×0.05 (tax amount), and we get as total
total cost = $13×(1+0.05) = $13×1.05 = $13.65
so, the decimal factor we can use directly without going through all the detail above is : 1.05

Answers
Answer:-105
Step-by-step explanation:
Answer:
Ok so, let's break it down
Step-by-step explanation:
-35+(-31)
Let's ignore the parenthesis and the - symbol
35+31
That would equal 66, so now we add back the - symbol which will make it -66
So we already have -66, so now we have -66+(-39)
We do the same thing we did with -35+(-31)
So we have 66+39
That makes -105
So your answer is -105

A triangle is shown
What is x?
What is y?
What is z?
Answers
Answer:
x = 44
y = 136
z = 136
Step-by-step explanation:
The angles of a triangle have to add up to 180°
54 + 82 + x = 180
136 + x = 180
x = 44
We know that y and z are vertical angles, so they have the same measurements.
Also, x and the other angle across from it are also vertical angles.
88 + 2n = 360
2n = 272
n = 136
Therefore,
x = 44
y = 136
z = 136

Deion is making sandwiches for a picnic. He uses 2 slices of cheese to make each sandwich,
and he has a package of cheese with 24 slices. How many sandwiches can Deion make before
he runs out of cheese?
answer quickly please!
Answers
Answer:
12 sandwiches
Step-by-step explanation:
We know that Deion has 24 cheese slices, and uses 2 slices per sandwich, so in order to find how many sandwiches he can make, we can divide the total number of cheese slices by the number used to make a sandwich:
24 / 2 = 12
Therefore, Deion can make 12 sandwiches before he runs out of cheese.

Rounding a decimal to the nearest whole number
If you have a decimal that is greater than or equal to 5 in the tenths place then you round up. Ex: 5.8 would be rounded to 6, 1.5 would be rounded to 2.
If you have a decimal that is less than or equal to 4 in the tenths place then you round down. Ex: 5.1 would be rounded 5, 1.2 would be rounded to 1.
Since 0 is in the tenth’s place we round down to 7.
