Answer:

The correct option is;

[tex]8.3 = -0.5 \times \left | x -5 \right | + 9[/tex]

Step-by-step explanation:

The coordinates of the roof are;

Starting point, = (1, 7)

Maximum height = (5, 9)

Maximum range = (9, 7)

The slope of the left portion of the roof = (9 - 7)/(5 - 1) = 0.5

The equation of the left portion of the roof is given as follows;

y - 9 = 0.5 × (x - 5)

y = 0.5 × (x - 5) + 9

The slope of the right portion of the roof = (7 - 9)/(9 - 5) = -0.5

The equation of the right portion of the roof is given as follows;

y - 9 = -0.5 × (x - 5)

y = -0.5 × (x - 5) + 9

However, when x < 5, we have;

[tex]0.5 \times \left | x -5 \right |= -0.5 \times \left | x -5 \right |[/tex]

[tex]\therefore y = 0.5 \times \left | x -5 \right | + 9 = -0.5 \times \left | x -5 \right | + 9 = 0.5 \times \left ( x -5 \right ) + 9[/tex]

When x > 5, we have;

[tex]0.5 \times \left | x -5 \right |> -0.5 \times \left | x -5 \right |[/tex]

[tex]\therefore y = -0.5 \times \left | x -5 \right | + 9 = -0.5 \times \left ( x -5 \right ) + 9[/tex]

Therefore, the equation that applies to both the left and right portion of the roof is [tex]y = -0.5 \times \left | x -5 \right | + 9[/tex]

Which gives the correct option as follows;

[tex]y = 8.3 = -0.5 \times \left | x -5 \right | + 9[/tex]

Answer: Choice A) Slope = -1

==============================================

Explanation:

The two points given to us are (x1,y1) = (0,-2) and (x2,y2) = (2,-4)

Subtract the y coordinates

y2-y1 = -4-(-2) = -4+2 = -2

Subtract the x coordinates in the same order

x2-x1 = 2-0 = 2

Divide the two results to get the slope m

m = (y2-y1)/(x2-x1)

m = -2/2

m = -1

Answer:

The answer would be 35.

Answer:

[tex]\frac{9}{16}[/tex]

Step-by-step explanation:

I hope this helps!

The expression (3/4 x 6/8) can be written as equivalent to 9/16.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. Example -  5/9. Here, (5) is called numerator and (9) is called denominator.

Given is the following expression -

3/4 x 6/8

The given expression is -

3/4 x 6/8

We can write -

(3 x 6)/(4 x 8)

18/32

Reducing to simple terms, we get -

9/16

Therefore, the expression (3/4 x 6/8) can be written as equivalent to 9/16.

Answer:

Suppose that the batch has N liters of paint.

we know that the recipe is:

1/2 of red paint

1/3 of yellow paint

1/6 of white paint.

Then, out of the N liters, 1/2 is red.

This means that we must use:

N/2 liters of red paint.

And the same for the other two colors:

N/3 liters of yellow paint

N/6 liters of white paint.

When we add those 3, we have:

(N/2 + N/3 + N/6)  = (3*N/6 + 2*N/6 + N/6) = N.

Now, if for example N = 2

Then the batch has 2 liters of paint, this would mean that we must use:

2/2 liters of red paint

2/3 liters of yellow paint

2/6 liters of white paint.

Answer:

q = infinite amount of solutions

Step-by-step explanation:

Step 1: Write equation

8q + 12 = 4(3 + 2q)

Step 2: Solve for q

--------------------------------------------------------------

We see here that you can plug in any number q and it would render the equation true. You can also look at it as 2 linear lines that are same, and the same line has infinite amount of solutions.

Step 3: Check

Plug in q to verify it's a solution.

8(0) + 12 = 4(3 + 2(0))

0 + 12 = 4(3 + 0)

12 = 4(3)

12 = 12

8(1) + 12 = 4(3 + 2(1))

8 + 12 = 4(3 + 2)

20 = 4(5)

20 = 20

We also see in the check step that any value q works.

The solution to the equation 8q + 12 = 4(3 + 2q) is Q can be any real number.

We have,

To solve for Q in the equation 8q + 12 = 4(3 + 2q), we can follow these steps:

Step 1: Distribute the 4 to the terms inside the parentheses:

8q + 12 = 4 * 3 + 4 * 2q

Simplifying further:

8q + 12 = 12 + 8q

Step 2: Combine like terms on both sides of the equation:

8q + 12 = 12 + 8q

Step 3: Subtract 8q from both sides of the equation to isolate the q term:

8q - 8q + 12 = 12 + 8q - 8q

Simplifying further:

12 = 12

Step 4: Since both sides of the equation are equal, the equation is true for all values of q.

This means the solution is all real numbers.

Therefore,

The solution to the equation 8q + 12 = 4(3 + 2q) is Q can be any real number.

42/5.25 = 8

8×5.25 = 42

Answer:

5 1/4 of 800 is 42

Step-by-step explanation:

Change 5 1/4 into a decimal = .0525

(.0525)x =42

divide both sides by 0.0525:

x = 42 / .0525

x = 800

5¼% of 800 is 42

Answer:

-1 and -5

Step-by-step explanation:

You must account for negative u values (which the abs nullifies).

So [tex]5u+15=10[/tex] and [tex]5u+15=-10[/tex] is what we have to solve for.

As for usual equations, isolate the u variable.

5u + 15 = 10

5u + 15 (-15) = 10 (-15)

5u = -5

[tex]\frac{5u}{5}=\frac{-5}{1}[/tex]

u = -1

Now you can do the same operation for the other equation and you should get u = -5.

Let's make sure we did it right by replacing u with one of our solutions (-1 or -5).

[tex]|5(-1)+15| = 10\\10 = 10[/tex]

That's true. What about the other one?

[tex]|5(-5)+15|=10\\10=10[/tex]
