Answer:
x = 2/3
y = -13/15
Step-by-step explanation:
3x – 8 = -6
+8 +8
[addition property of equality]
3x = 2
÷3 ÷3
[division property of equality]
x = 2/3 → -2x – 5y = 3
[substitution property]
-2(2/3) – 5y = 3
[distributive property]
-4/3 – 5y = 3
[Create the proportional equivalent of each term so that all terms share the same denominator]
-4/3 – 15y/3 = 9/3
[multiplication property of equality]
3 ( -4/3 – 15y/3 ) = 3 ( 9/3 )
[distributive property]
-4 – 15y = 9
+4 +4
[addition property of equality]
-15y = 13
÷-15 ÷-15
[division property of equality]
y = -13/15

Expand by multiplying each term in the first expression by each term in the second expression.
The easy way would be multiplying the first expression by 2x then set those numbers off to the side.
Then multiply the first expression by -3 and set those numbers off to the side as well.
Then add the numbers you put off to the side together.
This should result in: 2x^3 - 3x^2 + 10x^2 - 15x - 8x + 12
Combine the alike terms together
=2x^3 + 7x^2 -23x + 12

Step-by-step explanation:
Consider the following statement: Two sets of data with the same mean will also have the same variability. Do you agree or disagree with this statement? Explain.
The statement is false and same mean can have different variability
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the mean of the data be represented as M
Now , The mean is a measure of central tendency that represents the average value of a set of data, but it does not provide information about the variability or spread of the data.
For example, consider the following two sets of data:
Set 1: 1, 2, 3, 4, 5 (mean = 3)
Set 2: 0, 2, 3, 4, 6 (mean = 3)
Both sets have the same mean of 3, but Set 1 has a smaller range (4) compared to Set 2 (6). The range is a measure of variability that represents the difference between the maximum and minimum values in a set of data.
Hence , two sets of data with the same mean can have different variability,

(this is 6th grade math) please help whats the equation for this?
Answer:
t=100-s
Step-by-step explanation:
Since we know T as the total amount, we need to figure out how much was spent from the $100 Julie has. She can't gain more money magically so you have to take away from the 100. The amount taken away is the S (a.k.a- how much was SPENT). After putting that together, you get t=100-s.

Step-by-step explanation:
When two or more quantities have the same exponents, their bases can be multiplied together.
A survey revealed that 20% of workers at a company were satisfied with their job. If 30 workers selected this option. How many total workers are at the company? Use the model below to help you solve the question.
Answer:
150 workers are at the company
Step-by-step explanation:
If 20% of the workers is equal to 30 workers than in order to find 100% of the worker you need to multiply the percentage with a number that makes it 100% and then multiply that number to the 30 workers so
20% * 5 = 100%
30 * 5 = 150
so 100% of the workers is equal to 150 workers

The age of the oldest sibling is 15 years old.
What is consecutive number?
Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers.
Here, let the age of youngest sibling be x years
the age of middle sibling be (x+1) years
the age of oldest sibling be (x+2) years
According to question,
x + (x+1) + (x+2) = 42
3x + 3 = 42
3x = 39
x = 13
Thus, the age of the oldest sibling is (x+ 2) years = 15 years old.

10 ÷ 5 + 4 ( 72 - 6 )
Answer:
266
Step-by-step explanation:
A probability model includes P(red) = 27 2 7 and P(blue) = 314 3 14 . Which of the following probabilities could complete the model? Select all that apply. A. P(green) = 27 2 7 , P(yellow) = 27 2 7 B. P(green) = 38 3 8 , P(yellow) = 18 1 8 C. P(green) = 14 1 4 , P(yellow) = 14 1 4 D. P(green) = 521 5 21 , P(yellow) = 1121 11 21 E. P(green) = 37 3 7 , P(yellow) = 114 1 14
Answer:
[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]
[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]P(Red) = \frac{2}{7}[/tex]
[tex]P(Blue) = \frac{3}{14}[/tex]
Required
Which completes the model
Let the remaining probability be x.
Such that:
[tex]P(Red) + P(Blue) + x = 1[/tex]
Make x the subject
[tex]x = 1 - P(Red) - P(Blue)[/tex]
So, we have:
[tex]x = 1 - \frac{2}{7} - \frac{3}{14}[/tex]
Solve
[tex]x = \frac{14 - 4 - 3}{14}[/tex]
[tex]x = \frac{7}{14}[/tex]
[tex]x = \frac{1}{2}[/tex]
This mean that the remaining model must add up to 1/2
[tex](a)\ P(Green) = \frac{2}{7} ; P(Yellow) = \frac{2}{7}[/tex]
[tex]P(Green) + P(Yellow)= \frac{2}{7} + \frac{2}{7}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{2+2}{7}[/tex]
[tex]P(Green) + P(Yellow)= \frac{4}{7}[/tex]
This is false because: [tex]\frac{4}{7} \ne \frac{1}{2}[/tex]
[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{3}{8} + \frac{1}{8}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{3+1}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{4}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]
This is true
[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{4} + \frac{1}{4}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{1+1}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{2}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]
This is true

Answer:
y=-9/7x-15/14
Step-by-step explanation:
Slope-intercept form is y=mx+b
The y-coordinate is on one side, and the slope, x-coordinate, and y-intercept are on the other side.
18x+14y+15=0
-15 -15
18x+14y=-15
-18x -18x
14y=-15-18x
14y=-18x-15
