The slope and y-intercept of a graph can be determined by examining the equation of the line.
The slope is the coefficient of the x-term (the number next to x in the equation) and the y-intercept is the number that the line crosses the y-axis (the constant in the equation). For example, if the equation of a line is y = 2x + 5, then the slope is 2 and the y-intercept is 5. To graph the line, you can use the slope and y-intercept. Start at the y-intercept and move up or down the number of units indicated by the slope. For example, if the slope is 2, move two units up or two units down and plot a point. Repeat this process until the graph is complete.

The function increases when x > 1
The function increases when x > 2
The function increases when x > -3
According to the given image, the given function is increasing at (C) x > 2.
What are functions?A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X.
The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
The relationship between the input or domain and the output or range is known as the function rule.
If and only if there is a single value in the range for each domain value, a relation is a function.
A function is denoted by the notation f x, where x is the input value.
A function has the general form y = f x.
So, let's consider the given image:
The function is increased from the point +2 on the x-axis.
Which can be the point x > 2.
Therefore, according to the given image, the given function is increasing at (C) x > 2.

using substitution to solve the system below, what expression should be substituted into the first equation?
The expression should be substituted into the first equation is "x = 8 -2y" and also the value of x = 3 and y = 2.5
What do you mean by substitution?
The substitution method is an algebraic strategy for resolving simultaneous linear equations. This approach, as the name suggests, involves substituting the value of one variable from one equation into the second equation. This makes it easier to answer a pair of linear equations by combining them into a single equation with a single variable.
The equations given in the question,
2x - 4y = -4
x + 2y = 8
Let these two equation be named as 1 and 2 respectively.
Taking equation 2 and making x stay one side and all others on other side of the equation. We get,
x = 8 -2y
Substituting this value of x in equation 1.
2x - 4y = -4
2(8 - 2y) - 4y = -4
y = 2.5
substituting this value of y in equation 2,
x + 2y = 8
x = 8 - 5
x = 3
Therefore, The expression should be substituted into the first equation is "x = 8 -2y" and also the value of x = 3 and y = 2.5

Mickey earned $475 from mowing lawns last summer. He deposited this money in an account that pays an interest rate of 3. 8% compounded annually. What will be his balance after 4 years rounded to the nearest cent?.
The balance after 4 years is $551.42. Here we use the formula of compound interest to calculate the total amount or balance after 4 years.
Define compound interest.Compound interest is the interest calculated based on the initial principal and sum of the interests calculated over the previous time periods.
Formula for calculating the compound interest is:
A = P( 1 + [tex]\frac{r}{n}[/tex])^nt
Here A is the final amount accumulated
P is the Principal = $475
r is the interest rate = 3.8%
n is the number of times compounded in a year(here it is compounded annually) so n = 1.
t is the given time period = 4
Therefore
A = 475(1 + 3.8%)⁴
= 475(1.038)⁴
= 551.42$
Therefore total balance after 4 years is $ 551.42

Landon made plain cookies and raisin cookies in the ratio of 2:3
He then made 6 more raisin cookies and the ratio changed to 1:3.
How many cookies did Landon make in all?
Step-by-step explanation:
x = number pain cookies
y = number raisin cookies
x/y = 2/3
x/(y+6) = 1/3
x = (y + 6)/3
x = 2y/3
therefore,
x = x = (y + 6)/3 = 2y/3
y + 6 = 2y
6 = y
x = 2y/3 = 2×6/3 = 2×2 = 4
so, he made originally 4 + 6 cookies, and then he made 6 more raisin cookies, so, he made 4 + 6 + 6 = 16 cookies.

The null hypothesis get rejected comparing the 95% confidence interval to the proportion of the given central valley residents and bay area residents .
As given in the question,
Total number of voters in California = 7525
x₁ = Number of voters of central valley residents approved California legislature
= 68
n₁ = Total number of voters of central valley residents
= 200
x₂ = Number of voters of bay area residents approved California legislature

Using the percentage by volume of the solutions, we can calculate that we require 216 mL of 100% alcohol and 384 mL of 50% alcohol.
What is the percentage by volume?Volume/volume percentage is a unit used to represent how much of a substance is present in a solution.
It is sometimes referred to as v/v percent or %v/v.
It is calculated by dividing the volume of the solute by the total volume of the solution, then multiplying the result by 100.
So, we are aware of:
A + B = 600 mL
We also know that the total alcohol concentration of the final solution must be equal to:
0.68 * 600 mL = 408 mL
Therefore, it follows that:
0.50 * A + B = 408 mL
The first equation leads to the following conclusion:
A = 600 mL - B
Using that A in the second equation, we arrive at:
0.50 * (600 mL - B) + B = 408 mL
300 mL - 0.50 B + B = 408 mL
If we rewrite this equation as follows:
B - 0.50 * B = 408 mL - 300 mL
0.50 * B = 108 mL
B = 108 mL / 0.50
B = 216 mL
A = 600 mL - 216 mL = 384 mL
Therefore, using the percentage by volume of the solutions, we can calculate that we require 216 mL of 100% alcohol and 384 mL of 50% alcohol.

8. Determine the perimeter of Parallelogram STUV.
Round to the nearest hundredth, if necessary.
The answer to this Question Based on Perimeter is 8.72
What is Perimeter?
Perimeter is total length of boundary of any closed figure
Solution:
to calculate perimeter of this first we need to calculate the lengths of all sides
BY pythagoras theorem we can see that SV = sqrt(4^2 + 1^2)
SV = sqrt(17)
By similar procedure other lengths we can calculate as
UV = sqrt(5)
UT = sqrt(17)
ST = sqrt(5)
Hence perimeter will be sum of all these that is 2sqrt(5) + 2sqrt(17)
2(2.24) + 2(4.12)
4.48 + 4.24
8.72 will be perimeter

Multiple linear regression refers to a statistical technique used to predict the outcome of one variable based on the values of two or more variables. Sometimes simply called multiple regression, it is an extension of linear regression. The variable we want to predict is called the dependent variable, and the variables we use to predict the value of the dependent variable are called the independent or explanatory variables.

Yi is the dependent or predicted variable
β0 is the y-intercept, i.e., the value of y when both xi and x2 are 0.
β1 and β2 are the regression coefficients representing the change in y relative to a one-unit change in xi1 and xi2, respectively.
βp is the slope coefficient for each independent variable.
