Write each equation in slope-intercept form.
19. y - 4 = 3(x - 2)
20. y + 2 = -(x + 4)
21. y - 6 = -2(x + 2)
22. y + 1 = -5(x - 3)
23. y - 3 = 6(x - 1)
24. y - 8 = 3(x + 5)

Answer:

[tex]y=-\frac{1}{3}x+1[/tex]

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Where 'm' = slope of the line

b = y-intercept

From the picture attached,

b = 1

Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is represented by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of the line passing through the points (0, 1) and (3, 0) will be,

m = [tex]\frac{0-1}{3-0}[/tex] = [tex]-\frac{1}{3}[/tex]

Equation of the line will be,

[tex]y=-\frac{1}{3}x+1[/tex]

Step-by-step explanation:

when you look at a parallelogram, it could be a rectangle, square, or rhombus. so apply each of these statements to all of these shapes to see if they are true.

a. on a rectangle, not all sides are congruent. cant be that one

b. on a rhombus, not all angles are congruent. cant be that one

c. on a rhombus, the diagonals are not the same length. cant be that one

d. on every parallelogram, the opposite angles are congruent because that is what makes opposite sides parallel

14) No. 15) No. 16) Yes. 17) Yes.

Explanation:

When something is not a function, you can either use the vertical line test which involves drawing a line going up and down to see if the graph hits the line more than once. If this is the case, it is not a function. Or the input or x value of a function cannot have more than one

output or y value.

The line x = |y| on the graph of #14 is not a function because there is more than one y value for a single x value. This also hits a vertical line more than once.

The table on #15 is not a function because their is more than one y value per x value. It also hits a vertical line more than once.

The equation y = 1/4x is a function because there is only one output for each input. This also does not hit a vertical line more than once

The equation x = y - 1 is a function because it is simply a rearanged version of y = x + 1 which has only one output for each input. It also does not hit a vertical line more than once.

Answer:

[tex]Vc = 2,261.9\ in^3[/tex]

Step-by-step explanation:

Volume of a Cylinder

The volume of a cylinder of radius r in and a height h can be calculated by:

[tex]Vc=\pi\cdot r^2\cdot h[/tex]

The height of the cylinder is h = 20 in and the base radius is r = 6 in, thus:

[tex]Vc=\pi\cdot 6^2\cdot 20[/tex]

[tex]Vc = 2,261.9\ in^3[/tex]

Answer:

28+63

Step-by-step explanation:

Answer:

A) [tex]5x-1=-6[/tex]

B) [tex]x=-1[/tex]

Step-by-step explanation:

On the left, we have five (positive) Xs and one -1. So, we can represent the left with the expression [tex]5x-1[/tex].

On the right, we have six -1s. So, we can represent the right with the expression [tex]-6[/tex].

A)

Since the balance is balanced, we know that the two expressions are equal to each other. So, we can write the equation:

[tex]5x-1=-6[/tex]

B)

Now, we can solve the equation for x. Add 1 to both sides:

[tex](5x-1)+1=(-6)+1[/tex]

The left will cancel. Add on the right:

[tex]5x=-5[/tex]

Finally, divide both sides by 5:

[tex](5x)/5=(-5)/5[/tex]

The left side will cancel. So, the value of x is:

[tex]x=-1[/tex]

Answer:

A)  5x-1=-6

B) x=-1

The length of each side of the square will be 1 yard.

A square has four equal sides, and four vertices, and is a closed, two-dimensional object. It has parallel sides on either side. A square is also equivalent to a rectangle with equal length and width.

The square's perimeter is four times as long as its side.

For a square with a side length of a unit, we get:

Perimeter of the square = 4a unit

A square has a perimeter of 4 yards. Then the length of each side of the square will be given as,

4 = 4a

a = 1 yard

The length of each side of the square will be 1 yard.

Both are 123

When dealing with angles you have to remember that all angles add up to 180, “the line angle” as I like to call it, it’s because 180 is completely flat.

2: Here you can use your eyes to see the angle is wider than 90, ”a perfect right”. So you can easily assume that the angle is gonna be 123.

1: the angle here shares the same place as your original angle. So you can easily assume that they have the same degree

Answer: (F-G)(x)=5x2+2i +1

Step-by-step explanation

The resulting function for (f−g)(x) is 2x²+x-3

Let the required functions be:

f(x)=2x²+3x

g(x)=2x+3

We are required to find (f−g)(x).

(f−g)(x). = f(x) - g(x)

(f−g)(x) = 2x²+3x - (2x+3)

(f−g)(x) = 2x²+3x - 2x - 3

(f−g)(x) = 2x²+x-3

Hence the resulting function for (f−g)(x) is 2x²+x-3

Answer:

Explained below.

Step-by-step explanation:

Categorical variables are those variables that represents certain characteristic or attribute. Such as gender, eye color, age limit and so on.

Numerical variables are variables that assumes numerical values. Such as height, weight, time and so on.

Numerical variables are of two types: Discrete and Continuous.

Discrete variables are those variables that assumes finite whole number values. Such as number of girls in a house, number of children in the nursery and so on.

Continuous variables are those variables that assumes values from a fixed interval. Such as length of screw, amount of payment for donations and so on.

The attributes are classified as follows:

a. Brand of computer purchased by a customer : Categorical

b. State of birth for someone born in the United States : Categorical

c. Price of a textbook : Numerical and Discrete

d. Concentration of a contaminant (micrograms per cubic centimeter) in a water sample : Numerical and Continuous
