Answer:

Slope: 2/3

y-intercept: -3

Step-by-step explanation:

Subtracting both sides of the equation by 3 to make it in 'y=mx+c' form:

y + 3 - 3 = 2/3x - 3

y = 2/3x - 3

Seeing this,

m = 2/3

c = -3

Since m is the slope, the slope is 2/3

Since c is the y-intercept, the y-intercept is -3

Answer:-36

Step-by-step explanation:-3(-1)-12

so negative times negative is positive so -3 x -1 is 3 so now positive times negative is negative so 3 x -12 is -36

The statement which best describes all the possible values of m is –12 < m < 4.

The turning point of a function is defined as the point where the graph of the function changes it's form. That is, an increasing graph changes to decreasing at that point and vice versa.

Given a table values of function.

Also, given that, one of the turning point is at x = -1.

At x = -1, f(x) = 4.

After it, the function decreases.

We can also see another turning point at x = 1.

At x = 1, f(x) = -4.

After x = 1, the function again increases to get the value f(x) = -2.

So x = -2 is not a turning point.

So the value of f(-2) = m lies in between -12 and 4.

Hence the correct option is B.

Answer:

length-77m

Step-by-step explanation:

since we already know the area which is 4158m² and width which is 54m we will do the opposite of multiplication to find the length which is division you divide 4158 by 58 and we get 77m

The box with area of the base of the box is 112 square inches and the height is 3.5 inches has volume of 392 in³

A cuboid is a three dimensional shape polyhedral with six quadrilateral faces. The volume of a cuboid is:

Volume of cuboid = length * width * height

A box is a three dimensional shape in the form of a cuboid. The volume of a box is:

Volume of box = length * width * height

Volume of box = area of base * height

The area of the base of the box is 112 square inches and the height is 3.5 inches, hence:

Volume of box = 112 in² * 3.5 in

Volume of box = 392 in³

The box has volume of 392 in³

Answer:

x = 3

Step-by-step explanation:

(13x - 2) and (12x + 1) are vertically opposite angles and are congruent , so

13x - 2 = 12x + 1 ( subtract 12x from both sides )

x - 2 = 1 ( add 2 to both sides )

x = 3

Answer:

y-intercept is -18

Step-by-step explanation:

The total y=mx+b equation is y=4x-18, you can check in a calculator. I checked on a graphing calculator, and solved it via graphing on a piece of paper.

A line is drawn on the coordinate plane that passes through the point (3,-6) and has a slope of 4. The y-intercept of the line is -18.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

Given:

A line that passes through the point (x, y), with a y-intercept of b and a slope of m, can be represented by the equation,

y = mx + b.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

m = 4 (given)

So, the equation of the line is,

y - y₁ = m(x - x₁)    equation 1

And here

x₁ = 3 and y₁ = -6.

Substituting the values to the equation 1,

y - (-6) = 4 (x - 3)  

y+6 = 4x -12

y = 4x -18.

Comparing with the slope-intercept form,

we get y-intercept b = -18

Therefore, the equation is y = 4x -18 and y -intercept of the equation is -18
