Proportion A
The first thing you should know in this case is what the rate of change means.
The rate of change in a linear equation is given by the slope of the line.
For a linear equation, the rate of change is constant.
So we have to:
y = 9x
The slope is:
m = 9
Proportion B
The slope of the line will be:
m = (y2-y1) / (x2-x1)
Substituting values:
m = (57.5-34.5) / (5-3)
m = 11.5
Answer:
The rate of change in proportion A is 2.5 less than in proportion B.

Which measure is cloest to the length of a side of a square that has an area of 221 square feet? 11.0 ft 14.69 ft 16.4 ft 55.2 f

Degger [83]

Answer:

14.69 ft.

Step-by-step explanation:

Area of a square:

A= $a^2$

Given:

A=221 $ft^{2}$

Solve:

221= $a^2$

$\sqrt{221}$ = $\sqrt{a}^2$

a is approx. equal to 14.87 ft.

which is 14.69 ft.

Find X. Give your answer in the simplest form.

mojhsa [17]

Answer: 8

Step-by-step explanation:

We can use trigonometry to solve this:

If we call the angle at the top Ф then x is the opposite and 8 is the adjacent

Therefore we use Tan to solve this:

Tan Ф = opposite/adjacent

Tan 45 = X/8

1 = X/8

8 x 1 = X

Therefore X = 8

Write the equation of a line that is parallel to the given line and passes through the given point.

rodikova [14]

Answer:

$y=\frac{1}{3}x +5$

Step-by-step explanation:

Linear equations are typically formatted in slope-intercept form:

$y=mx+b$ where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)

<u>1) Determine the slope (m)</u>

Parallel lines will always have the same slope. Therefore, this line will also have a slope of $\frac{1}{3}$ . Plug this into our equation:

$y=\frac{1}{3} x+b$

<u>2) Determine the y-intercept (b)</u>

To solve for the y-intercept (b), plug the given point (-3,4) into our equation and isolate b.

$4=\frac{1}{3}(-3)+b\\4=\frac{-3}{3}+b\\4=-1+b$

Add 1 to both sides

$4+1=-1+b+1\\5=b$

Therefore, the y-intercept is 5. Plug this back into our original equation with the slope:

$y=\frac{1}{3}x +5$

I hope this helps!
