Answer:

8a + 6b = 3

Step-by-step explanation:

Simplifying

8a + 6b = 3

Solving

8a + 6b = 3

Solving for variable 'a'.

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

Add '-6b' to each side of the equation.

8a + 6b + -6b = 3 + -6b

Combine like terms: 6b + -6b = 0

8a + 0 = 3 + -6b

8a = 3 + -6b

Divide each side by '8'.

a = 0.375 + -0.75b

Simplifying

a = 0.375 + -0.75b

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

tanx = [tex]\frac{sinx}{cosx}[/tex] , sin²x + cos²x = 1, secx = [tex]\frac{1}{cosx}[/tex]

Consider left side

tanAsinA + cosA

= [tex]\frac{sinA}{cosA}[/tex] × sinA + cosA

= [tex]\frac{sin^2A}{cosA}[/tex] + cosA

[tex]\frac{sin^2A+cos^2A}{cosA}[/tex]

= [tex]\frac{1}{cosA}[/tex]

= secA = right side , thus proven

The rate of flow in cups per year is  3645 cups per year.

To convert the rate of flow from quarts per day to cups per year, we first need to convert quarts to cups and days to years.

1 quart is equal to 4 cups,

So 5 quarts is equal to 5 x 4 = 20 cups.

1 year is equal to 365 days, so

2 days is equal to 2/365 = 1/182.5 years.

So the rate of flow in cups per year is 20 cups / (1/182.5 years) = 3645 cups per year.

Answer:

A

Step-by-step explanation:

Adding positively to an x moves it right, and negative moves left. Adding to a y moves it up, and subtracting moves it down.

The transformation that moves figures to the right 3 units and down 7 units is A. (x, y) ⇒ (x + 3, y - 7)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Translation is the movement of a point up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units right and b units down, the new location would be at A(x + a, y - b).

A function that moves figures to the right 3 units and down 7 units can be represented by:

(x, y) ⇒ (x + 3, y - 7)

Answer : Rena's weekly gross earnings are $976.31.

Step-by-step explanation :

As we are given total earning of Rena per year is $50,768.

Now we have to calculate her weekly gross earnings.

As we know that in one year there are 52 weeks.

That means,

1 year = 52 weeks

According to the question:

As, Rena earns in 52 weeks = $50,768

So, Rena earns in 1 week = [tex]\frac{\$ 50,768}{52}[/tex]

                                          = $976.31

Therefore, Rena's weekly gross earnings are $976.31.

Answer:

y=41  73=x

Step-by-step explanation:

180=x+9+98

minus 98 from both sides

82=x+9

minus 9 from both sides

73=x

2y=x+9 because they are corresponding angles

2y=73+9

2y=82

divide by 2 on both sides

y=41

Answer:

A

Step-by-step explanation:

6 friends

Mean - 10

Median - 9.5

Range - 14

3 friends watched 12, 13, and 18 movies.

Let's find the sum, this will help us find the total number of movies the other 3 friends watched.

12 + 13 + 18 = 43

The mean is all their movies added toether, divided by the number of friends.

m = number of movies the other friends watched.

(43 + m) / 6 = 10        Multiply each side by 6

43 + m = 10 * 6

43 + m = 60          Subtract 43 from each side

m = 60 - 43

m = 17

So we know the total movies the other friends watched is 3.

A. 4+6+7 = 17

B. 4+4+7 = 15

C. 5+8+9 = 22

D. 2+3+5 = 10

We know the answer is A.

We can check it by looking at the Median, the median is the middle number, if there are an even number of samples, you add the 2 middle numbers together and divide by 2.

4, 6, 7, 12, 13, 18

So 7+12 = 19

19/2 = 9.5

So we know for sure A is correct!

Answer:

[tex]\frac{-1}{6}[/tex]
