Answer:

rotated about 180 degrees clockwise

Step-by-step explanation:

Triangle C is in the first quadrant and this transformation is done by translating triangle A by a vector (-3,1) and then rotating the triangle B by 180 degrees.

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

From the given graph, the vertices of triangle A are (1, -1), (1, -4) and (3, -4)

The given vector is (-3, 1).

Translate triangle A by a vector (-3,1) to give triangle B.

Then rotate your triangle B 180 degrees around the origin to give triangle C.

The following steps can be used to describe the transformation that maps triangle A onto triangle C:

Step 1 - Triangle A is given in the fourth quadrant.

Step 2 - Now, as per the given data translate triangle A by a vector (-3,1) which means the triangle shift in the negative x-axis by a factor of 3 and also shift downwards in the negative y-axis by a factor of 1.

The resulting triangle is in the third quadrant which is triangle B.

Step 3 - Now, rotate the triangle B by 180 degrees. So, the resulting triangle is triangle C which is in the first quadrant.

Therefore, triangle C is in the first quadrant and this transformation is done by translating triangle A by a vector (-3,1) and then rotating the triangle B by 180 degrees.

The maximum profit is $923.44 which is gotten when 83 T shirts are produced.

Given the function:

Profit = Revenue - Cost

Profit (P) = 100x - (0.6x²+0.52x+3200)

P = -0.6x² + 99.48x - 3200

The maximum profit is at dP/dx = 0, hence:

dP/dx = -1.2x + 99.48

0 = -1.2x + 99.48

1.2x = 99.48

x = 82.9

x ≅ 83

The maximum profit is at x = 83, hence:

P = -0.6(83)² + 99.48(83) - 3200

P = 923.44

y = 2x + 1

Step-by-step explanation:

1. Find the slope;  (change in y values)/(change in x values)

Slope = (-5 - 3)/ (-3 - 1) = -8/-4 = 2

2. Find the y-intercept (b) using  the slope intercept formula: y = mx + b

    m = 2 and using point (1, 3) , solve for "b"

       y = mx + b

       3 = 2(1) + b

       3 = 2 + b

      1 = b

Answer:

Slope: 2

Y-intercept:  (0, -1) or - 1

Step-by-step explanation:

Given the linear equation, -4x + 2y = -2:

Transform the given equation into its slope-intercept form, y = mx + b:

-4x + 2y = -2

Add 4x to both sides:

-4x + 4x + 2y = 4x - 2

2y = 4x - 2

Divide both sides by 2 to isolate y:

[tex]\frac{2y}{2} = \frac{4x - 2}{2}[/tex]

y = 2x - 1 ⇒ This is the slope-intercept form where the slope, m = 2, and the y-intercept is (0, -1).

Answer:

  p : q : r = 3 : 18 : 2

Step-by-step explanation:

Given:

  p : q = (1/3) : 2

  p : r = (3/4) : (1/2)

Find:

  p : q : r

Solution:

We want to rewrite these ratios so they use the same number for p. We can do that by using the least common multiple of (1/3) and (3/4) for p. That value is 3.

  p : q = (9)(1/3) : (9)(2) = 3 : 18

  p : r = (4)(3/4) : (4)(1/2) = 3 : 2

Then the ratio of interest is ...

  p : q : r = 3 : 18 : 2

Additional comment

We are not often asked to find the least common multiple of fractions or mixed numbers. One way to do it is to write the numbers using a common denominator, then find the LCM of the numerators, and reduce any resulting fraction.

  LCM(1/3, 3/4) = LCM(4/12, 9/12) = (1/12)·LCM(4, 9) = 36/12 = 3

__

As with integers, you also have ...

  LCM(1/3, 3/4) = product/GCD = (1/3)(3/4)/GCD(1/3, 3/4)

The greatest common divisor (GCD) will be the unit fraction with the least common denominator: 1/12, so this is ...

  LCM(1/3, 3/4) = (1/3)(3/4)/(1/12) = (3/12)/(1/12) = 3

A system of equations consists of at least two equations

The value of x is [tex]\mathbf{x = \frac{y}2 +2}[/tex]

The equation is given as:

y = 2x - 4

The actual question is to solve for x.

So, we start by adding 4 to both sides of the equation

y +4 = 2x - 4 + 4

y +4 = 2x

Rewrite the equation as:

2x= y +4

Divide both sides of the equation by 2

[tex]\mathbf{\frac{2x}2 = \frac{y +4}2}[/tex]

Divide 2x by 2

[tex]\mathbf{x = \frac{y +4}2}[/tex]

Split the fraction

[tex]\mathbf{x = \frac{y}2 +\frac{4}2}[/tex]

Simplify

[tex]\mathbf{x = \frac{y}2 +2}[/tex]

Hence, the value of x is [tex]\mathbf{x = \frac{y}2 +2}[/tex]
