The hour hand of a clock moves from 6

90 degrees. Looking at a clock, 12 o'clock going all the way around and back is a 360 degree spin. So 12, 3, 6, and 9 are all 1/4 of a 360 degree spin. If you divide 360 by, you would get a 90 degree turn for each of those numbers mentioned above.

Angles around a point adds up to 360°. the clock is divided into 12 parts to read time, so first we should divide 360° by 12.
360°÷12=30,
difference between 6 and 9 is 3 so, next we have to multiply 30 by 3.
30×3=90
answer-90°

Consider the square root function f(x) = sqrt x + 2 + 1 to complete the table of values below. find each missing value and then

Scrat [10]

Given the function :

$f(x)=\sqrt[]{x+2}+1$

We need to find each missing value

Given x = -3 , -2 , -1 , 2 , 7

So, substitute with each value of x to find the corresponding value of f(x)

$x=-3\rightarrow f(x)=\sqrt[]{-3+2}+1=\sqrt[]{-1}+1$

So, there is no value for f(x) at x = -3 (the function undefined because the square root of -1)

$\begin{gathered} x=-2\rightarrow f(x)=\sqrt[]{-2+2}+1=\sqrt[]{0}+1=0+1=1 \\ \\ x=-1\rightarrow f(x)=\sqrt[]{-1+2}+1=\sqrt[]{1}+1=1+1=2 \\ \\ x=2\rightarrow f(x)=\sqrt[]{2+2}+1=\sqrt[]{4}+1=2+1=3 \\ \\ x=7\rightarrow f(x)=\sqrt[]{7+2}+1=\sqrt[]{9}+1=3+1=4 \end{gathered}$

the graph of the function and the points will be as shown in the following image :

3x + 2y = 6

Step-by-step explanation:

x = cost of 1 hot dog

y = cost of 1 drink

Neveah: 2x + y = 3.75

Jason: 3x + 2y = 6

PLEASE HELP ME!!!!!!!!!

Answer:

(a) (5, -3)

Step-by-step explanation:

The "substitution method" for solving a system of equations requires that you write an expression that can be substituted for a variable in one or more of the other equations in the system.

<h3>Expression to substitute</h3>

The given equations are ...

y = x -8
2x +3y = 1

We notice the first equation gives an expression for y. This is exactly what we want to substitute for y in the second equation.

<h3>Substitution</h3>

When the expression (x-8) is substituted for y in the second equation, you get ...

2x +3(x -8) = 1

This simplifies to ...

5x -24 = 1

<h3>Solution</h3>

This 2-step equation can now be solved in the usual way:

5x = 25 . . . . . . add 24 to isolate the variable term

x = 25/5 = 5 . . . . . divide by the coefficient of x

Note that we now know what the correct answer choice is.

Using the expression for y, we find ...

y = x -8 = 5 -8 = -3

The solution is (x, y) = (5, -3).

The attached graph confirms this solution.

You can make a 6 x 6 square to illustrate the probabilities

1 2 3 4 5 6
1 2 3 4 5 6 7
2 3 4 5 6 7 8
3 4 5 6 7 8 9
4 5 6 7 8 9 *
5 6 7 8 9 * &
6 7 8 9 * & $

* =10, & =11, $ = 12, I wanted maintain spacing

There are 3 4's. So it is 3/36 chance, which is 1/12 chance.
