Number 3 is x=5 and number 4 is x=63
Best Answer:
<span> 3/4 = 0.75
7/50 = 0.14
13/25 = 0.52
17/25 = 0.68
1/20 = 0.05
7/10 = 0.7
To get the decimal you always divide numerator by denominator. So, the process becomes:-
3/4 = 3 ÷ 4 = 0.75
7/50 = 7 ÷ 50 = 0.14
13/25 = 13 ÷ 25 = 0.52
17/25 = 17 ÷ 25 = 0.68
1/20 = 1 ÷ 20 = 0.05
7/10 = 7 ÷ 10 = 0.7 </span>
The key feature of the functions that are needed to determine if the lines intersect are;
- The slope; rate of change
- The y-intercept
<h2>
Slope and y-intercept</h2>
From straight line geometry, we can conclude that two parallel lines whose slope are equal can never intersect.
On this note, for the functions described in the question, the functions only intersect when the slopes are different.
Additionally, the functions may intersect in the event of having equal y-intercepts.
In order two straight lines in a coordinate plane intersect, they MUST have different slopes.
This condition is NECESSARY and SUFFICIENT.
That's OK, but you have not said which variable you want to solve it for.
<u>To solve for 'x':</u>
<span>c + ax = dx
Subtract c from each side: ax = dx - c
Subtract dx from each side: ax - dx = -c
Factor the left side: x (a - d) = -c
Divide each side by (a - d) : x = -c / (a - d) or <u>x = c / (d - a)</u> .

Answer:
$0.36
Step-by-step explanation:
How to calculate unit price:
unit price = total price divided by quantity (length in this case)
3.24 divided by 9 = 0.36
Best of luck :3
