Answer: 
Step-by-step explanation:
This car follows a line, hence its motion can be modeled by the Line equation.
In fact, we already have two points of the line, if we call
the time in hours and
the traveled distance in miles:
Point 1:
Since we are told the car's initial position is 300 miles in the time 0 h
Point 2:
Since we are told the car's final position is 180 miles after 3h

<u>Let's find the Slope
:
</u>
This is the slope of the line
Now, the equation of the line is:
We already know the slope, now we have to find the intersection point with the y-axis (
) with any of the given points. Let's choose Point 1:
Isolating
:
Then, the equation of the line is:
Answer:
x = 21.6
Step-by-step explanation:
<u>Solution by Cross Multiplication</u>
For the equation
35=x36
The cross product is
3×36=5×x
Solving for x
x=3×365
and reducing
x=21.6
<u>Solution by Proportion</u>
Since the equation is an equality
If
36 ÷ 5 = 7.2
Then it is true that
x ÷ 3 = 7.2
Solving for x
x = 3 × 7.2
x = 21.6
Answer:
in my words proportional means having equal portions lets say you cut a pizza into 4 separate pieces if you had 1 piece that was half and three pieces random that is not proportional but if you have 4 quarters that is proportional
Step-by-step explanation:
Answer:
your mom
Step-by-step explanation:
Use the elimination method to get rid of one of the variables.
Find the value of one variable.
Find the value of the remaining variables using substitution.
Clearly state the final answer.
Check your answer by substituting both values into either of the original equations.
Answer: -2.1, -0.5, 5/100, 0.5, √5
Step-by-step explanation:
Start with the negative numbers. Take the absolute value - the ones with the largest absolute value are the farthest from 0, so they are the smallest numbers.
-2.1, -0.5
Then, convert the numbers not in decimals to decimals.
5/100 = 0.05
√5 is about 2.3.
5/100, 0.5, √5
