y2 =3
y1 = 0
x2 = -1
x1 = - 2
Formula
m = (y2 - y1)/(x2 - x1)
Solution
m = (3 - 0) / (-1 - - 2)
m = (3 )/ (-1 + 2)
m = 3/1
m = 3

Al and Tom are painting a shed. Working alone, Al can paint the shed in 2 hrs. Together they can paint the shed in 1.5 hours. How long would it take Tom to paint the shed on his own?
Answers
Answer:
6 hours.
Step-by-step explanation:
The formula sort of has to be invented.
Al
rate = 1 shed / 2 hours
Tom
rate = 1 shed / x hours.
Together.
rate = 1 shed / 1.5 hours.
Equation
1 shed / 2 hours + 1 shed / x hours = 1 shed / 1.5 hours.
1/2 + 1/x = 1/1.5 Put the fractions over a common denominator.
(x + 2) / 2x = 1 / 1.5 Cross Multiply
1.5(x + 2) = 2x Remove the Brackets.
1.5x + 3 = 2x Subtract 1.5x from both sides
3 = 2x - 1.5x
3 = 0.5x Multiply both sides by 2
6 = x
It would take Al 6 hours to do the shed on his own.

if x,y are in inverse proportion then complete the following table x= 42 y=-15 , x=30 y=-----
Answers
Answer:
when x=30, y = -21
Step-by-step explanation:
x = k/y
x = 42 y = -15
x = k/y
42 = k/-15
Cross product
42 * -15 = k
-630 = k
k = - 630
Find y when x=30
x = k/y
30 = -630/y
Cross product
30 * y = - 630
30y = - 630
y = - 630/30
y = -21
when x=30, y = -21

Answer: A
Step-by-step explanation: This is a rotation. An easy way to tell the difference between a rotation and a reflection is that the order of the points will not change in a rotation. For this problem, pre-image ABCD is still in the order of ABCD when mapped to the image. (You can still follow along the points in that order). When something is reflected, the points swap orders and you would not be able to follow the points in order.
Now that we know this is a rotation, Notice A’ B’ C’ and D’ are all left of the pre-image. This means the mapped image moves counter clockwise.

How to solve inequality equations?
An inequality is a mathematical expression using the symbols >, <, ≥, and ≤. Many straightforward inequalities can be resolved by adding, taking away, multiplying, or dividing both sides until the variable is all that remains. On multiplying or dividing both sides with negative number changes the direction of inequality. If we flip the number, we just have to flip the inequality symbol also.
Inequality:
2x-3> 2x-5/2
2x - 2x > -5/2 + 3
2x - 2x > -2.5 + 3
0 > -2.5 + 3
0 > 0.5
This shows that solution set will not contain any elements, i.e. x ∈ ∅
Therefore, Solution set = ∅

Find the measure of each interior angle and each exterior angle of a regular 90-gon.
Answers
Answer:
Interior angle
176 degrees
Exterior
4 degrees
Step-by-step explanation:
Exterior angle
For any polygon, the measure of the total exterior angle is 360
To get the individual exterior angle, we divide the total by n, which is the number of sides, 90 in this case
We have this as;
360/90 = 4
Interior
To get the measure of each interior angle, we use the formula below;
[(n-2)180]/n
n in this case is 90
So we have
[(90-2)180]/90
= (88 * 180)/90
= 2 * 88 = 176

Circle A has center of (6, 7), and a radius of 4 and circle B has a center of (2, 4), and a radius of 16.
Answers
Answer:
See solutions below
Explanation
We are to find the equation of circle A and B
The equation of a circle is expressed as;
(x-a)^2 + (y-b)^2 = r^2
(a, b) is the centre and r is the radius
For Circle A that has center of (6, 7), and a radius of 4
Substitute;
(x-6)^2 + (y-7)^2 = 4^2
(x-6)^2+(y-7)^2 = 16
Hence the equation of circle A is (x-6)^2+(y-7)^2 = 16
For circle B:
If circle B has a center of (2, 4), and a radius of 16
The equation is expressed as;
(x-2)^2+(x-4)^2 = 16^2
(x-2)^2+(x-4)^2 = 256
Hence the required equation is (x-2)^2+(x-4)^2 = 256

the lengths of the sides of a triangle are 2n, n^2 and n+5 for what value of n do these lengths not make a triangle ?
Answers
Answer:
Step-by-step explanation:
Try n = 2
2n = 4
n^2 = 4
n+5 = 7 That works. It will make a triangle since the 2 smallest numbers are bigger than 7
Try n = 3
2n = 6
n^2 = 9
n + 5 = 8 That works. Same reason as above.
n = 4
2n = 8
n^2 = 16
n + 5 = 9 That works. Same reason.
n = 5
2n = 10
n^2 = 25
n+5 = 10 Aha! That doesn't work. the two smaller numbers only = 20.
There are likely many numbers that don't work. I'll try one more
n = 6
2n = 12
n + 5 = 11
n^2 = 36 This won't work either. Same reason as n = 5.

Compare the theoretical probabilities to your experimental probabilities. Why might there be a difference?
Answers
Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.

Answer:
Theoretical probability is what is expected to happen, where as experimental probability is what happens when you test out that theory. There is a very unlikely chance that a concept in theory would be the same as a concept in action, therefore explaining why these answers are not alike.
