Answer:

7 sqrt(2)

Step-by-step explanation:

We can use trig functions

sin theta = opposite side/ hypotenuse

sin 45 = 7/x

Multiply each side by x

x sin 45 = 7

Divide each side by sin 45

x = 7 / sin 45

x = 7 (sqrt(2) /2)

x = 14 / sqrt(2)

We do not leave square roots in the denominator

x = 14 / sqrt(2) * sqrt(2)/ sqrt(2)

12 sqrt(2)/ 2

= 7 sqrt(2)

C(n) = -7 + 6(n - 1)

Pavel [41]

Answer:

6n-13

Step-by-step explanation:

Since the question given is -7+6(n-1)

-7+6(n-1)

Open the bracket first

-7+6n-6

Collect like terms

-7-6+6n

-13+6n

Which can also be written as

6n-13

So C(n)=6n-13

Underline all the ordered pairs (x,y) that are solutions to the equation y=2x+1.

Romashka [77]

Answer:

(3,7) (7,3) (−1,14) (0,1) (12,25)

(5,11) (0,12) (1,8) (12,0) (−1,−1)

Step-by-step explanation:

We have the following function:

$y = 2x+1$ .

We are going to check if each ordered pair is a solution.

(3,7)

If when $x = 3, y = 7$ , it is a solution.

$y = 2x + 1 = 2(3) + 1 = 7$

This ordered pair is a solution.

(7,3)

If when $x = 7, y = 3$ , it is a solution.

$y = 2x + 1 = 2(7) + 1 = 15$

This ordered pair is not a solution.

(-1,14)

If when $x = -1, y = 14$ , it is a solution.

$y = 2x + 1 = 2(-1) + 1 = -1$

This ordered pair is not a solution.

(0,1)

If when $x = 0, y = 1$ , it is a solution.

$y = 2x + 1 = 2(0) + 1 = 1$

This ordered pair is a solution.

(12,25)

If when $x = 12, y = 25$ , it is a solution.

$y = 2x + 1 = 2(12) + 1 = 25$

This ordered pair is a solution.

(5,11)

If when $x = 5, y = 11$ , it is a solution.

$y = 2x + 1 = 2(5) + 1 = 11$

This ordered pair is a solution.

(0,12)

If when $x = 0, y = 12$ , it is a solution.

$y = 2x + 1 = 2(0) + 1 = 1$

This ordered pair is not a solution.

(1,8)

If when $x = 1, y = 8$ , it is a solution.

$y = 2x + 1 = 2(1) + 1 = 3$

This ordered pair is not a solution.

(12,0)

If when $x = 12, y = 0$ , it is a solution.

$y = 2x + 1 = 2(12) + 1 = 25$

This ordered pair is not a solution.

(-1,-1)

If when $x = -1, y = -1$ , it is a solution.

$y = 2x + 1 = 2(-1) + 1 = -1$

This ordered pair is a solution.

-1/2x-3=4 Solve for x

sleet_krkn [62]

Answer:

x=-3.5

reason:

first, add 3 to both sides
this makes the equation -1/2x=7
then, divide both sides by -1/2
this will give you x=-3.5

Find the measure of angle x in the figure below: 50° 75° 115° 130°

kvv77 [185]

Your answer is 50°
This is because angles in a triangle add up to 180°, so you can do 65 + 65 = 130, and then 180 - 130 = 50, and since angle x is opposite that angle, then angle x is 50°

I hope this helps!
