Answer:

To find the constant of proportionality from the coordinates of

one point on the graph are as follows :-

1.) Find two easy points.

2.) Start with the leftmost point and count how many squares you need to up to get to your second point.

3.) Count how many squares you need to go to the right.

4.) Simplify, and you've found your constant of proportionality.

Answer:

0 I think??

Step-by-step explanation:

$M=\frac{x2-x1}{y2-y1}$

$M=\frac{7-(-8)}{3-3}$

$M=\frac{15}{0}$

$M=0$

.Bryan was given the equation y= -5x+3. He says the rate of change is 3 and the initial value is -5. Is Bryan correct? If not, c

Mekhanik [1.2K]

Answer:

Correct rate of change is -5; correct initial value is 3.

Step-by-step explanation:

The rate of change is the coefficient of the x term, which here is -5. So Bryan has the rate of change wrong.

The initial value of the function is found by letting x = 0. Here, we get

y = -5(0) + 3, or y = b = 3. The initial value is 3, not -5.

Write the standard form of the line that contains a slope of and y-intercept of 3. Include your work in your final answer.

Brut [27]

Standard form is y=mx+b, where m is the slope and b is the y intercept, substitute to find y=3x+3.
Hope this helps!

Tacoma's population in 2000 was about 200 thousand, and has been growing by about 8% each year. If this continues, what will Tac

Anestetic [448]

Answer:

Tacoma's population in 2014 will be 587,439 people

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by the formula

$y=a(1+r)^x$

where

y is Tacoma's population in thousand

x is the number of years since 2000

r is the rate of change

a is the initial value

we have

$a=200\\r=8\%=8/100=0.08$

substitute

$y=200(1+0.08)^x$

$y=200(1.08)^x$

what will Tacoma's population be in 2014?

Find the value of x

$x=2014-2000=14\ years$

substitute the value of x

$y=200(1.08)^{14}=587.439\ thousand$

therefore

Tacoma's population in 2014 will be 587,439 people
