Which is the equation of a line whose slope is -2 and whose y-intercept is 3?

marusya05 [52]

Answer:

y = -2x + 3

Step-by-step explanation:

The slope-intercept formula for a line is y = mx + b where m is the slope and b is the y intercept. Therefore, just sub -2 for m and 3 for b.

3. Caleb has $25 to spend on prizes for a game at the school fair. Lip balm costs $1.25 each, and mini-notebooks cost $2.50 each

Snowcat [4.5K]

Answer:

linear equation in Standard form that can be used to determine how many of each prize Caleb can buy is $1.25x+ 2.50y = 25$

Step-by-step explanation:

Given:

Total cost spent on prizes for games = $25

Cost of one lip balm = $1.25

Cost of one mini notebook = $2.50

A) linear equation in STANDARD FORM that can be used to determine how many of each prize she can buy.

Let the number of lip balms be x and the number of mini note books be y. Then

$1.25x+ 2.50y = 25$

B. Graph the equation using x- and y- intercepts.

Now by trial and error method

$1.25(0)+ 2.50(10) = 25$

$1.25(2)+ 2.50(9) = 25$

$1.25(4)+ 2.50(8) = 25$

$1.25(6)+ 2.50(7) = 25$

$1.25(8)+ 2.50(6) = 25$

$1.25(10)+ 2.50(5) = 25$

$1.25(12)+ 2.50(4) = 25$

$1.25(14)+ 2.50(3) = 25$

$1.25(16)+ 2.50(2) = 25$

$1.25(18)+ 2.50(1) = 25$

$1.25(20)+ 2.50(0) = 25$

Thus Caleb can buy 0,2,4,6,8,9,10,12,14,1,6,18,20 lip balms and

0,1,2,3,4,5,6,7,8,9,10 mini note books respectively

Now plotting these value in the graph, we get the below graph

Kevin is observing the population of the fish he put into a pond. He built a pond and populated it with 500 fish. The population

laila [671]

Here we will use exponential form, which is

$y = y_{0} e^{kt}$

Initial value, y0 = 500

Double of 500 = 1000

$1000 = 500e^{k*1}$

$2 = e^k$

$k= ln (2)$

Required equation is

$y=500e^{x ln2} \\ y= 500 (2)^x$
