Answer:
y = 3-8 =-5
Step-by-step explanation:
mark me as brainliest ❤️
hi <3
you have to isolate the variable 'y'
to do that, just subtract 8 from both sides of the equation
thus, y = 3 - 8
giving you an answer of y = -5
hope this helps :)

Jim washes 2/3 of his car with 1/2 a bottle of soap. What fraction of the soap will he use to clean his entire car?
Answer:
if he uses 1/2 for 2/3, then you can divide 2/3 and 1.2 by 2 to get the remaining soap needed to complete the wash
so to clean the last 1/3 of the car, he`ll use 1/4 of the remaining soap
the entire car needs 3/4 of a bottle of soap

The correct option is (a) i.e. Regression equations are usually used to predict values of unavailable data. If the data do not closely model a particular type of function, then that type of function is not appropriate to use in statistical regression. The more closely data fit a model, the more accurate predicted values will be.
What is Regression analysis?
A collection of statistical techniques known as regression analysis is used to estimate the associations between a dependent variable and one or more independent variables. It can be used to simulate the long-term link between variables and gauge how strongly the relationships between them are related.
Although there are non-linear regression techniques for more complex data and analysis, simple linear regression and multiple linear regression are the two fundamental types of regression. While multiple linear regression employs two or more independent factors to predict the outcome, simple linear regression just uses one independent variable to explain or predict the outcome of the dependent variable Y. (while holding all others constant).
Professionals in other industries, including banking and investment, might benefit from regression. Regression can also aid in predicting sales for a business based on external factors like the weather, past sales, GDP growth, and other variables. A popular regression model in finance for valuing assets and calculating capital expenses is the capital asset pricing model (CAPM).

A nurse mixes 40 cc of a 70% saline solution with a 20% saline solution to produce a 36% saline solution. How much of the 20% solution should he use?
00
The amount of 20% saline solution needed is
CC.
B
We will need 85cc of 20% saline solution for the mixture
Let the amount of 20% saline solution be "a"
If a nurse mixes 40 cc of a 70% saline solution with a 20% saline solution to produce a 36% saline solution, then the finished product will be 40 + a cc which containing 36% saline solution.
The saline content will therefore be expressed as:
(70% of 40)+20% of a = 36% of (40 + a)
0.7*40 + 0.2a = 0.36(40 +a)
28 + 0.2a = 14.4+0.36a
28 - 14.4 = 0.36a - 0.2a
13.6= 0.16a
a = 13.6/0.16
a = 85
This means that we will need 85cc of 20% saline solution for the mixture

Compare the numbers 6x10-6 to 2x10-8.
Which number has the greater value?
Which number has the lesser value?
How many times greater is the greater number?
Answer:
6×10-6 have greater value than 2×10-8
Step-by-step explanation:
6×10-6
60-6
=54
And
2×10-8
20-8
=12
Thus, 6×10-6 had the greatest value by 42 more than 2×10-8
6×10-6 have greater value than 2×10-8
The greater value is 600 x 10⁻⁸. And the lesser value is 2 x 10⁻⁸. The number 600 x 10⁻⁸ is 300 times greater number 2 x 10⁻⁸.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Compare the numbers 6 x 10⁻⁶ and 2 x 10⁻⁸.
Then the numbers can be written as,
⇒ 6 x 10⁻⁶ and 2 x 10⁻⁸
⇒ 600 x 10⁻⁸ and 2 x 10⁻⁸
The number 600 x 10⁻⁸ times greater than the number 2 x 10⁻⁸ will be
⇒ 600 x 10⁻⁸ / 2 x 10⁻⁸
⇒ 300
The greater value is 600 x 10⁻⁸. And the lesser value is 2 x 10⁻⁸. The number 600 x 10⁻⁸ is 300 times greater number 2 x 10⁻⁸.
