Which Expression Has A Value Of 30 When X = -1 And Y = 3?

Answers

Answer 1

Answer:

B. (x - 3²)(y-6)

Step-by-step explanation:

Find the expression with a value of 30;

 when x  = -1 and y = 3:

   A.  (x - 3²).y-6

           (-1 - 9).3-6 = -10 x 3 -6  = -30 - 6 = -36

 B.  (x - 3²)(y-6)

          ( -1 -3²)(3 - 6) = (-1 -9)(-3) = 30

C.  x - 3² . (y-6) = -1 - 9.(3-6)

                         = -1-9.-3

                         = -1 - 9 x -3

                         = -1 + 27

                         = 26

D. x - 3².y-6 = -1 - 9. 3 - 6

                   = -1 - 27 - 6

                   = -34

Identify one point and the slope from the equation y + 4 = 1/3(x - 1)
Options:
m = 4 Point = (1/3, 1)

m = 1/3 Point = (1, -4)

m = 1/3 Point = (1, 4)

m = 1/3 Point = (-1, 4)

Answers

Answer:

m = 1/3 Point = (1, -4)

The slope is 1/3.

The point is 1,-4.

If you are wondering how I got the point, I just unsimplified the equation!

From y+4=1/3(x-1).

To y- -4=1/3(x-1).


The original formula is y-y1=m(x-x1). So we know where the y and the x is, and the slope.

Hope this helped!! :)

Answers

Step-by-step explanation:

start at the 6 then go down 2 Y and over 5X

Answer:

See explanation below

Step-by-step explanation:

Start at (0,6) which is the y-intercept where b=6, then go down 2 units, and 5 units to the right which represents the slope m=-2/5 and mark that point. Repeat until you feel you're done and then connect the points to form the line of the equation.

For example, the next point after (0,6) would be (5,4) because by going 5 units to the right and 2 units down, we can represent this as (0+5,6-2) which is (5,4). I've attached a graph with some points to help draw the line.

Write an expression to represent the perimeter of the figure below.

Answers

Step-by-step explanation:

A perimeter is when you add up all of the sides

Here would be our equation

[tex]2(x+4)+2(2x-8)[/tex]

Answer: The expression for this would be 2(x+4) + 2(2x-8)

Step-by-step explanation:

This is because when we calculate perimeter, we add up all the sides. So, instead of doing (x+4)+(x+4), we can just do 2(x+4) and add up all sides. So, here’s the answer in simplest form!

Answers

Answer:

(2.5, -2.5)

Step-by-step explanation:

I think that's right. Quadrant IV is when (x, -y)

The point in Quadrant IV that is 4 units away from point (-1.5, -2.5) on the coordinate plane is (2.5, -6.5)

What is the coordinate plane?

A coordinate plane is a two-dimensional plane formed by the intersection of two number lines.

Given that, there is a point in quadrant IV that is 4 units away from point (-1.5, -2.5) on the coordinate plane.

If we have a coordinate point (x, -y) in quadrant 4, if the coordinate is 4 units away, the resulting coordinate will be expressed as (x+4, y-4)

(-1.5+4, -2.5-4) = (2.5, -6.5)

Hence, The asked point is, (2.5, -6.5)
