Answer:

C) Subtract the sum 15 and 12 from 40

Step-by-step explanation:

Can someone help me and explain what to do here?
Vesna [10]

Answer:

 ∠STU = 69°

Step-by-step explanation:

The angle with vertex T is called an "inscribed angle." It intercepts arc SU. The relationship you are asked to remember is that the measure of the inscribed angle (T) is half the measure of the arc SU.

Point V is taken to be the center of the circle. The angle with vertex V is called a "central angle." It also intercepts arc SU. The relationship you are asked to remember is that the measure of the central angle (V) is equal to the measure of arc SU.

__

Using these two relationships together, we realize angle V is twice the measure of angle T:

  ∠SVU = 2×∠STU

  18x +12° = 2(18x -57°) . . . . . . relationship between the marked angles

  18x +12° = 36x -114° . . . . . eliminate parentheses

  126° = 18x . . . . . . . . . . . add 114°-18x

  ∠STU = 18x -57° = 126° -57°

 ∠STU = 69°

_____

<em>Additional comment</em>

You may notice we did not solve for x. We only needed to know the value of 18x, so we stopped when we found that value. (Actually, we only need the value of 18x-57°. See below.)

__

<em>Alternate solution</em>:

  (18x +12°) -(18x -57°) = 18x -57° . . . . . . . subtract 18x -57° from both sides of the first equation.

  69° = 18x -57° . . . . . simplify. This is the answer to the problem.

Which function is the verse of f(x)=2x+3?
Hatshy [7]

Answer:

Option B is correct

Step-by-step explanation:

A function has form of f(x) = 2x + 3, or y = 2x + 3

To find the inverse of f(x), we are going to represent x in form of y.

To do this, we try to send all components containing x to one side of expression and send the other components to the other side of expression.

Now, let's do it.

y = 2x + 3

We firstly send 3 to the right, change the sign of 3 from + to -, we have:

y - 3 = 2x

We then rearrange both sides to get a standard form:

2x = y - 3

We now divide both sides by 2 to get the expression of x:

(2/2)x = (y - 3)/2

We simplify both sides of expression to obtain final result:

x = (1/2)y - 3/2

=> Inverse of f(x) is x = (1/2)y - 3/2

=> Option B is correct

ira [324]

Answer: 17 pages

Step-by-step explanation:well you would have to divide 544 by 9 to see hao many pages you would need for the blue book

544/9= 60.44 which would be 61

then you would have to divide 544 by 7 to see hao many pages you would need for the red book

544/7= 77.71 which would be 78

the you would subtract 78 by 61 to see how many more pages you would need
