Wich of the following equations would NOT contain the point (4,12)

nlexa [21]

Given:

The given point is (4,12).

To find:

The equation that would NOT contain the point (4,12).

Solution:

We need to check each equation for the point (4,12).

In option A, the given equation is:

$y=-2x+20$

Putting $x=4$ , we get

$y=-2(4)+20$

$y=-8+20$

$y=12$

This equation contains the point (4,12).

In option B, the given equation is:

$y=\dfrac{1}{2}x+8$

Putting $x=4$ , we get

$y=\dfrac{1}{2}(4)+8$

$y=2+8$

$y=10$

This equation does not contain the point (4,12).

In option C, the given equation is:

$y=-\dfrac{1}{2}x+14$

Putting $x=4$ , we get

$y=-\dfrac{1}{2}(4)+14$

$y=-2+14$

$y=12$

This equation contains the point (4,12).

In option D, the given equation is:

$y=\dfrac{3}{4}x+9$

Putting $x=4$ , we get

$y=\dfrac{3}{4}(4)+9$

$y=3+9$

$y=12$

This equation contains the point (4,12).

Only the equation in option B does NOT contain the point (4,12). Therefore, the correct option is B.

Solve for x. Round to the nearest TENTH of a degree. Type your answer as a single value (don't type "x=" or include any labels).

8090 [49]

Answer:

x = 36.9

Step-by-step explanation:

Use the sine function if you know the length of the opposite side and the hypotenuse. Plug your values into the equation: sine (x) = opposite ÷ hypotenuse. Say that the length of the opposite side is 6 and the length of the hypotenuse is 10. Divide 6 by 10, which is equal to 0.6. Now you know that sine (x) = 0.6 which is the same as x = sine^-1 (0.6).

Steps:

sin (x) = 6/10

sin(x) = 0.6

then we do sin^-1(0.6), which equals 36.869897645844 ° (degrees)

36.869897645844 ° (degrees) rounded to the nearest tenth is 36.9

so x = 36.9
