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:

Simplifying

c + -2 = 3c + 14

Reorder the terms:

-2 + c = 3c + 14

Reorder the terms:

-2 + c = 14 + 3c

Solving

-2 + c = 14 + 3c

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-3c' to each side of the equation.

-2 + c + -3c = 14 + 3c + -3c

Combine like terms: c + -3c = -2c

-2 + -2c = 14 + 3c + -3c

Combine like terms: 3c + -3c = 0

-2 + -2c = 14 + 0

-2 + -2c = 14

Add '2' to each side of the equation.

-2 + 2 + -2c = 14 + 2

Combine like terms: -2 + 2 = 0

0 + -2c = 14 + 2

-2c = 14 + 2

Combine like terms: 14 + 2 = 16

-2c = 16

Divide each side by '-2'.

c = -8

Simplifying

c = -8

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

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

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:-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.
