Answer: 6.

Explanation:

The picture is blur.

I got that answer and will explain you the solution assuming the expression is:

8 + 24 ÷ (2 x 6) - 4.

Before adding 8 to 24 ÷ (2 x 6) you have to solve 24 ÷ (2 x 6).

Start by solving the parenthesis: (2 X 6) = 12

Now perform the division: 24 ÷ 12 = 2

Now you can add and subtract: 8 + 2  - 4 = 10 - 4 = 6.

You can perform these operations directly in an ordered way:

8 + 24÷(2x6) - 4 = 8 + 24÷12 - 4 = 8 + 2 - 4 = 6

Caitlin drew a scale drawing of the community park in her town. The actual
Tom [10]

Answer: 1 inch equals 4 feet

Step-by-step explanation:

By an online search, I´ve found that:

The park is 48 ft long.

Caitlin´s drawing is 12 inches long.

To find how much each inch represents, we need to take the quotient between those lengths:

48ft/12in = 4ft/in.

We also can write this amount as:

4 feet per inch.

This means that each inch represents 4 feets.

Then the correct option is the first one:  1 inch equals 4 feet

Determine m∠U if m∠R = 9x - 10 and m∠U = 3x + 4.
german

Answer:

50.5 degrees

Step-by-step explanation:

Since this is a parallelogram then...

Angle U + Angle R = 180

3x+4+9x-10=180

Combine like terms

12x-6=180

Add 6 to both sides

12x=186

Divide both sides by 12

x=15.5

Now we plug 15.5 in for x to find Angle U

3(15.5)4=46.5+4=50.5

Angle U = 50.5 degrees

Explain how you determine an equation for a line using a table of input/output values.
Lubov Fominskaja [6]
Example :

            x               y
            1               3
            2               6
            3               9
            4               12

first thing u do is pick any 2 points (x,y) from ur table

(1,3) and (2,6)
now we sub those into the slope formula (y2 - y1) / (x2 - x1) to find the slope
(y2 - y1) / (x2 - x1)
(1,3)....x1 = 1 and y1 = 3
(2,6)...x2 = 2 and y2 = 6
sub
slope = (6 - 3) / (2 - 1) = 3/1 = 3

now we use slope intercept formula y = mx + b
y = mx + b
slope(m) = 3
use any point off ur table...(1,3)...x = 1 and y = 3
now we sub and find b, the y int
3 = 3(1) + b
3 = 3 + b
3 - 3 = b
0 = b

so ur equation is : y = 3x + 0....which can be written as y = 3x...and if u sub any of ur points into this equation, they should make the equation true....if they dont, then it is not correct

and if u need it in standard form..
y = 3x
-3x + y = 0
3x - y = 0 ...this is standard form

The function f is defined by f(x) = 2x²-1.<br> Find f (2x).
umka21 [38]

Answer: f(2x)=8x^2-1

Step-by-step explanation:

All that is required here is to substitute x = 2x into the right side in the same way that is done for a numeric value.

f(2x) = 2(2x)^2-1\\f(2x) = 2(4)x^2-1\\f(2x) = 8x^2-1\\
