Answer: (-10, 20) and (6.5, 14)
Step-by-step explanation:
When x is -3 the equation would look as so:
y=6(-3)+8
y=-18+8
Then you would simplify: -18+8=-10
So: y=-10 when x is -3
Next, when x is 2 the equation would look as so:
y=6(2)+8
y=12+8
Simplify: 12+8=20
So: y is 20 when x is 2
For the equation y=1.5x+11 and x is -3 the equation will look like:
y=1.5(-3)+11
y=-4.5+11
Simplify: -4.5+11= 6.5
So y is 6.5 when x is -3
Next when x is 2 the equation would look like:
y=1.5(2)+11
y=3+11
Simplify: 3+11=14
So y is 14 when x is 2
Write the equation in slope intercept form. -5y + 10x = 20 help meeee

% (answer as a percent round to the nearest whole percent)
The probability of rolling dice twice
What is Probability?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Total no. of outcomes = 6
The probability of getting a 1,2 or 3 from the first rolling is 3/6.
The probability of getting a 5 or 6 from second rolling is 2/6
As the two rollings are independent,
you can just multiply two probability values to come up with a final answer.
Which is,
= (3/6) x (2/6)
= (1/2) x (1/3)
= (1/6)
The probability a rolling a 1, 2 or 3 on a number cube on your first roll, then a 5 or 6 the second roll is 1/6 or 0.16
Probability in % will be
0.16 x 100/100

C1 Determine the Greatest Common Factor of polynomials
To find the greatest common factor of a polynomial, find a number that all of its coefficients are divisible by, for example, the GCF of an 8x 2 + 4x + 2 is 2 because all of the coefficients (8, 4, 2) are divisible by 2 and the expression simplifies to 2(4x2 + 2x + 1).
What is the Greatest Common Factor?A group of numbers' greatest common factor (GCF) is the biggest factor that all the numbers have in common. For instance, the numbers 12, 20, and 24 share the components 2 and 4. The GCF of 12, 20, and 24 is 4 because it is the largest.
To find the greatest common factor of a polynomial, find a number that all the coefficients of the polynomial are divisible by i.e. the GCF of a 8x^2 + 4x + 2 is 2 because all the coefficients (8, 4, 2) are divisible by 2 and the expression simplifies to 2(4x^2 + 2x + 1).
The GCF can be smaller than the smallest coefficient, for example 20x^2 + 15x + 10 (GCF is 5, smallest coefficient is 10) and 5 < 10. However it cannot be larger than the smallest coefficient.
Therefore the smallest coefficient should be larger than or equal to the GCF in order to be divisible.

What is volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity. The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.

Find JKL and LKM if JKM = 140.
The measure of angles JKL and LKM are 100° and 40° respectively.
What is a supplementary angle?A supplementary angle simply refers to two (2) angles or arc whose sum is equal to 180 degrees.
Additionally, the sum of all of the angles on a straight line is always equal to 180 degrees. In this scenario, we can logically deduce that the sum of angles JKL, LKM and JKM are not supplementary angles:
m∠JKL + m∠LKM = m∠JKM
Substituting the given parameters into the formula, we have;
4x° + (2x − 10)° = 140°
6x° − 10 = 140°
6x° = 140° + 10°
6x° = 150°
x° = 150/6
x = 25°
For angle JKL, we have:
m∠JKL = 4x
m∠JKL = 4(25)
m∠JKL = 100°.
For angle LKM, we have:
m∠LKM = 2x − 10
m∠LKM = 2(25) − 10
m∠LKM = 50 − 10
m∠LKM = 40°

5. Find the selling Price of an item that originally cost a store $70 was marked up20% and then after no selling for 6 months was discounted 10%?
Answer:
$75.6
Explanation:
If the original cost was $70 and it was marked up 20%, the price after this is calculated as:
$70 + $70(0.2) = $70 + $14 = $84
Where $70(0.2) = $14 is the amount added to the original when it is marked up 20%.
Then, it was discounted 10%, we get that the selling price is
$84 - $84(0.1) = $84 - $8.4 = $75.6
Where $84(0.1) = $8.4 is the discount made on the initial price.
Therefore, the answer is $75.6

The length of A'B' = 5 units
The line segment AB is of 5 units. AB is then transformed through translation of 3 units to the right.
The translation only means change through a straight line. This transformation does not change the length of a line segment.
So the length of A'B' will also be 5 units.
But the position of A'B' will be different from that of AB on the co-ordinate plane. To be exactly, A'B' would be 3 units right to the position of AB on the co-ordinate plane.

A)278
B)288
C)298
D)388
Answer: A
Step-by-step explanation:
First you multiply 138 x 14 =1932 then divide 28 then you have 69 then add 209 then you have 278.
sorry if its wrong.
Answer:
A) 278
Step-by-step explanation:
Use PEMDAS for order of operations:
Start with anything in parentheses, and then operations are performed on any exponents (also called powers). Next, perform operations on multiplication or division from left to right. Finally, operations on addition or subtraction are performed from left to right.
Kimi and Jordan are both working during the summer to earn money and they are saving all their money. Kimi earns $9 an hour at her job, and has $6 saved up initially. Jordan earns $7.50 an hour, and has $18 saved up initially.
Using linear functions, it is found that they will have the same amount after 8 hours.
What is a linear function?A linear function, in slope-intercept format, is given by:
y = mx + b
In which the coefficients are described as follows:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the y-axis(x = 0).In the context of this problem, for their earning functions, we have that:
The slope is represented by the hourly earnings.The intercept is represented by the initial amount saved.Hence the functions are given as follows:
Kimi: K(x) = 6 + 9x.Jordan: J(x) = 18 + 7.5x.The number of hours after which they will have the same amount is found solving the following equation for x.
K(x) = J(x)
6 + 9x = 18 + 7.5x.
1.5x = 12
x = 12/1.5
x = 8 hours.
What is the missing information?This problem is incomplete, hence we suppose that it asks after how many hours they will have the same amount.
