Answer:
x=5, y=-2. (5, -2).
Step-by-step explanation:
2x+3y=4
3x+4y=7
----------------
3(2x+3y)=3(4)
-2(3x+4y)=-2(7)
----------------------
6x+9y=12
-6x-8y=-14
-----------------
y=-2
2x+3(-2)=4
2x-6=4
2x=4+6
2x=10
x=10/2
x=5
Answer:
200,000 m
Step-by-step explanation:
We will multiply the length of the ant by the number of ants to find out how long the line is.
10 million is 10 with 6 zeros
20 * 10 ^-3 move the decimal 3 places to the left
20. * 10 ^-3 = .02
.02 * 10000000
200000
Answer:
just doing this for my points!!! lol
Step-by-step explanation:
Answer:
Y= 5/6x+5
Step-by-step explanation:
Okay same as before
the slope is rise over run
The rise is 5
The run is 6
So 5/6
And since ts rising from left to right its positive
The y-intercept which is the first point the line touches the Y axis is 5
So y=5/6x+5
Answer:
See attachment for plot
Step-by-step explanation:
Given

--- increment in the rate
First, we need to model the new rate
A linear equation is:

Where

Compare
and
. we have:

The above represents the previous rate.
The new rate:

Rewrite as:



So, the model is:


<u>The plot at 1 and 2 minutes</u>
When 

When 

So, we have:


<em>Whether she moves backwards or forward, the distance covered remains the same</em>
