Yes, the equation is balanced. (brainliest?)
Answer:
y = x + 3 or y = 1x + 3
Step-by-step explanation:
Since we're just going to find the equation (assuming it's slope-intercept form, which is <em>y = mx + b</em>), our jobs will be relatively simple!
Let's start with the first step and identify the y-intercept, which is the easiest step.
That will be (0,3), as the line intercepts the y-axis there.
Next, let's find the slope of the line using
or
. Just be careful when using
that you correctly identify the scale the axis' are using.
For now, I'll use
. Let's pick two points... (0,3) and (1,4).

= ![\frac{1}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B1%7D)
This will be our slope, 1.
We now have our answer, y = 1x + 3.
Hope that helped!
To answer this item, we formulate an equation that would relate the time, rate, and the final time.
A(t) = (Ao)(2)^(t/4)
We solve for the value of Ao by substituting the known values,
11 = (Ao)(2)^(50/4)
Ao = 1.89 x 10^-3
A quarter of 11 is 11/4. Using this value and the other known.
11/4 = (1.89 x 10^-3)(2)^(t/4)
The value of t from the equation is 42 minutes.
Answer:
3602
Step-by-step explanation:
Formula = Population after n years = 2000( 1.04)^n
15 years the population will be 2000(1.04)^15
=3602.
80 + 5 is 85 in extended form
