Answer:

Step-by-step explanation:

Convert to the slope-intercept form:

y = mx + b

2x + y = -12 subtract 2x from both sides

y = -2x - 12

1. Take any value of x.

2. Put it to the equation.

3. Calculate the value of y.

Examples:

for x = 0

y = -2(0) - 12 = 0 - 12 = -12

for x = -6

y = -2(-6) - 12 = 12 - 12 = 0

for x = 2

y = -2(2) - 12 = -4 - 12 = -16

1/3 = /6 - 1/6 = /6 How do you find the unlike denominator. Can you explain

lakkis [162]

Answer:

Okay So I see you need to change 1/3 to a denominator of 6

You don't do anything to the -1/6

But to change the 1/3 you need to multiply 3 and 1 by two, which is 2/6

And the -1/6 stays the same

Answer:

the answer is 12 cm

Step-by-step explanation:

Because of 8 cm on the small one, the 16 is double that, which means that 6 on the small would be 12 on the large

Which of the following functions has a range of all real numbers?

serious [3.7K]

Only the function in C has the range of all real numbers.
Later on, when you will be familiar with more type of functions you will know that when x is on the power range is usually only positive values or negative values if only not shifted, even if shifted it will only add to its range this numbers by which unit it was shifted.
B is shifted parabola. It has the range of {y| -3≤∞}

A kite is stuck in a 36-ft tree. If the angle of elevation from the kite and the ground is 12, find the length of the kite.

yanalaym [24]

Answer:

173.15 ft.

Step-by-step explanation:

Please find the attachment.

Let L be the length of kite.

We have been given that a kite is stuck in 36-ft tree. The angle of elevation from the kite and the ground is 12.

We can see from our attachment that kite and tree form a right triangle. height of tree is opposite of angle of elevation and length of kite is hypotenuse.

Since we know that Sine relates the opposite and hypotenuse of a right triangle, so we will use sine to find the length of kite.

$sin(12)=\frac{36}{L}$

$L=\frac{36}{sin(12)}$

$L=\frac{36}{0.207911690818}$

$L=173.1504364105882792\approx 173.15$

Therefore, the length of kite is 173.15 ft.
