Answer: I am going tot give you an example for this because I don’t like giving straight up answers ok?

Step-by-step explanation:

Lets use this conversion factor:

4 inches = 1 year

Let's find the year at 5 feet (60 inches) using the conversion factor. Set up a proportion.

4 / 60 = 1 / x

Cross multiply.

4x = 60

x = 15

At 15 years, the height is 60 inches.

We can use these as points.

x = time in years

y = height in inches

Point 1 = (1, 4)

Point 2 = (15, 60)

By looking at the points, we know that as the x values increase, so does the y values. Now the relation between the x and y values of each point is that y is 4 times as that of x. Therefore, we can establish an equation.

y = 4x

This will be the model to use to find the height in 30 years.

If arc AD = 62° and arc BC = 28°, then what is the measure of angle AED?
nata0808 [166]
Well according to the Inscribed Angle Theorem, the angle inscribed in a circle is equal to one-half of its intercepted arc. We can apply that theorem to this problem as well. So the measure of AED = 1/2( arc AD + arc BC). Plug in the numbers and simplify.
AED = 1/2( 62 + 28)
AED = 1/2( 90 )
AED = 45
So the measure of angle AED is B. 45 degrees.

The line is parallel to
tino4ka555 [31]

Recall that parallel lines have the same slope.

A line parallel to y= (-3/5)x + 8 would have the same equation EXCEPT for a different constant, C, replacing that '8.'

This new line passes thru (-5,-3).  In y= (-3/5)x + C, replace x with -5 and replace y with -3.  Then:

-3 = (-3/5)(-5) + C.  Find C:

-3 = 3 + C.  Thus, C = 6


Thus, the equation of the new line is y= -(3/5)x - 6

Check:  Let x = -5 and y = -3.  Is the above equation true?

-3 = (-3/5)(-5) - 6

-3 = 3 - 6, or -3 = -3.
