Answer:

k = -13/3 or ≈ -4.33

Step-by-step explanation:

-2= k+7/3

We can rewrite it for easy look:

k + 7/3 = -2

Subtract 7/3 from both side, we got:

k + 7/3 - 7/3 = -2 - 7/3

k + 0 = -2 - 7/3

Multiply -2 by 3 so it can subtract with - 7/3

k = -6/3 - 7/3

k = -13/3 or ≈ -4.33

-2= k+7/3

Move +7/3 to the other sign. Sign changes from +7/3 to -7/3.

-2-7/3=k+7/3-7/3

-2-7/3=k

find the common denominator for -2 which is 3.

Multiply by 3 for -2/1

(-2)(3)/1(3)

-6/3-7/3

=-13/3 or in mixed fraction - 4 1/3

Answer: k= -13/3 or k=-4 1/3

7x+3+6x+11 can u give a example of how to solve it
yKpoI14uk [10]

Combine like terms.

Since 7x and 6x both have a variable of x, you can combine them.

7x + 6x = 13x

After that, you are left with:

13x + 11 + 3

You also have two numbers without variables; 11 and 3. You can also combine those.

11 + 3 = 14

So, your final answer would be:

13x + 14

can someone help me solve A and B and you will be given rewarded points if yours is the first correct answer
Margaret [11]

Answer:

Angle A= 120⁰.. Angle B=60⁰

Step-by-step explanation:

To find angle A, you subtract 60 from 180, which would be 120. Angle A and 60⁰ are supplementary angles, meaning they have to add up to 180.

To find angle B, you take 360, since all the interior angles of that shape add up to 360.

360-90-90-120=60

A point on the terminal side of an angle in standard position is given. Find the exact value of each of the six trigonometric fu
Nataly [62]
Refer to Figure 1 for the diagram of the point and reference triangle needed to answer the problem.

Plot the point (2,-3) which is in quadrant 4

Draw a right triangle such that one leg is resting on the x axis and the other leg is perpendicular to the x axis. The hypotenuse goes from (0,0) to (2,-3). 

The horizontal leg is 2 units long. So a = 2
The vertical leg is 3 units long. So b = 3
The hypotenuse is unknown but we can use the pythagorean theorem to find it. We'll call it c for now

Use Pythagorean theorem to find c
a^2 + b^2 = c^2
2^2 + 3^2 = c^2
4 + 9 = c^2
13 = c^2
c^2 = 13
c = sqrt(13)
The hypotenuse is sqrt(13) which is shown in the attached image (Figure 1)

Using figure 1, now refer to figure 2 to compute the ratios for sine, cosine and tangent
Figure 3 shows how to compute the ratios for cosecant, sectant, and cotangent

Note: With figure 1, the leg furthest from angle theta is the opposite side (in this case -3). The leg closest to the angle theta is 2 units long.
