1) 8y=-5x+12
y= (-5/8)x+3/2
2) 2y=3x+7
y= (3/2)x+7/2
3) -3y= -2x+7
y=(2/3)x-7/3
4) -4y= -12x+16
y=3x-4
5) -2y= -x+10
y=(1/2)x-5
Hope this helps!
Answer:
( 3,0) .
Step-by-step explanation:
Given : Graph .
To find : What is the x intercept of the graph shown below.
Solution : We have given Graph .
X - intercept : is that point on x axis at which y = 0.
We can see from the given graph on x axis where y = 0 .
At x = 3 , y= 0
So , x - intercept is 3
Therefore, ( 3,0) .
Each pad of paper cost 3.25. Here is how I found it.
21.75 x 3 = 65.25
75 - 65.25 = 9.75
9.75 / 3 = 3.25
X = 3.25
Is this what you were looking for?
The vertex-form of a quadratic equation is

, where (h, k) is the vertex of the parabola.
To complete the square of a quadratic expression in standard form, we write the coefficient of x as 2*b, then add and subtract

.


so b=4, now add and subtract

.


Answer:
<em>The initial population size is 500 fish</em>
<em>Population size after 9 years: 1910 fish</em>
Step-by-step explanation:
<u>Mathematical Model</u>
We usually represent real situations as mathematical functions or rules that express the dependency of one variable quantity P with another variable quantity t.
The population size of a species of fish P(x) is modeled by the following function:

Where t is the number of years elapsed since the species was added to the lake.
The initial population size can be found by substituting t for 0:



P(0)=500
The initial population size is 500 fish
The population size after t=9 years is:




Population size after 9 years: 1910 fish
