Answer:

y = -1/4x - 6

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Find points from the graph.</em>

Point (-4, -5)

y-intercept (0, -6)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{-6+5}{0+4}
  2. Add:                              m=\frac{-1}{4}

<u>Step 3: Write linear function</u>

y = -1/4x - 6

Each side of the square below is 8 inches. A triangle inside of a square. The top of the triangle divides a side of the square i
dmitriy555 [2]

The probability that a point is chosen at random in the square is in the blue region is 0.8.

<h3>What is Probability?</h3>

The probability helps us to know the chances of an event occurring.

\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}

As we know that the area of the shaded region is the sum of the area of triangle A and the area of triangle B. Therefore, the area of the blue shaded region is,

\text{Area of shaded region} = (\dfrac{1}{2} \times 8 \times 8) + (\dfrac{1}{2} \times 4 \times 8)

                                  = (32) + (16)\\\\= 48\rm\ in^2

The area of the square can be written as,

\text{Area of Square} = \rm(Side)^2 = 8^2 = 64\ in^2

Now, the probability that a point is chosen at random in the square is in the blue region can be written as,

\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\

\rm Probability = \dfrac{\text{Area of blue region}}{\text{Area of square}}\\\\Probability = \dfrac{48}{60} = 0.8

Hence, the probability that a point is chosen at random in the square is in the blue region is 0.8.

PLZ HELP 20 POINTS FOR THE ANSWER.<br><br> BTW THERE IS ANSWER CHOICE F WHICH IS NONE OF THE ABOVE
SpyIntel [72]

Answer:

F. None of the above

Step-by-step explanation:

A cone is produced by rotating the shape about line m.

The height of the cone will be 0.5 because it's perpendicular to the base.

Since the height is 0.5, the answer is not A or B.

The circular base is formed by the line split into two "1"s. Each "1" is the radius, together, the diameter of the base.

Since r = 1, the answer is not C.

Since d = 2r = 2(1) = 2, the answer is not D.

∴ The answer is none of the above, F.
