Y - 3 = 12 (x - 4)
y - 3 = 12x - 48
y = 12x - 45 is your answer

(edit)
y - 3 = 1/2 (x - 4)
y - 3 = 1/2x - 2
y = 1/2x + 1 is your answer

If I were to tell a kid how to use the formula (the SA of a pyramid it looks like):

First, find the area of the base of the figure, using length times width.

Next, find the perimeter of the base by adding up the length of each side of the base.

Multiply the perimeter of the base by the slant height of the figure, which is the line on the side of the figure that is diagonal.

Divide the answer you got from multiplying the perimeter of the base times the slant height of the base by 2.

Now add up the area of the base of the figure with the answer you just got by dividing the perimeter of the base times the slant height by 2.

That is how you use the formula: SA = B + 1/2(P · l)

Answer:

A. Solutions are: x = 2, y = 1.

B. Solutions are: x = 3, y = 2.

1. Inconsistent

2. Inconsistent

3. Consistent

Step-by-step explanation:

A. Solutions of each system of linear equations by substitution method:

Equation 1: 3x - 2y = 4

Equation 2: x = 2y

Step 1: Substitute x = 2y into the Equation 1:

3(2y) - 2y = 4

6y - 2y = 4

4y = 4

Step 2: Divide both sides of the equation by 4 to isolate y:

$\frac{4y}{4} = \frac{4}{4}$

y = 1.

Step 3: For Equation 2, x = 2y, substitute y = 1 into the equation to solve for x:

x = 2y

x = 2(1)

x = 2

Therefore, the solutions are: x = 2, y = 1.

B. Find the solutions of each system of linear equations by elimination method:

Equation 1: 2x + y = 8

Equation 2: x + y = 5

Step 1: Multiply Equation 2 by 2:

2(x + y) = 5(2)

2x + 2y = 10

Step 2: Subtract Equation 1 from the equation derived from Step 1, 2x + 2y = 10:

2x + 2y = 10

- 2x + y = 8

y = 2

Step 3: Plug in y = 2 into Equation 1, 2x + y = 8 to solve for x:

2x + y = 8

2x + (2) = 8

Step 4: subtract both sides of the equation by 2 to isolate x:

2x + 2 - 2 = 8 - 2

2x = 6

Step 5: Divide both sides of the equation by 2 to solve for x:

$\frac{2x}{2} = \frac{6}{2}$

x = 3.

The solutions are: x = 3, y = 2.

1. Inconsistent

2. Inconsistent

3. Consistent (infinitely many solutions)

A bag contians 5 blue and 8 red and 7 green marbels. A marble is selacted at random. Find the propobility the marbelis not red.

sammy [17]

Total number of marbles = 5 + 8 + 7 = 20

Total number of non-red marbles = 5 + 7 = 12

P(not red) = 12/20 = 3/5

Answer: 3/5
