Answer:
y=x squared-2x-3
Step-by-step explanation:
I hope this helps
Minus the 21 from the other side of the equation making it 7x=-21 then u divide the 7 from the x to the -21 resulting in x=-3
D cause of biology hope this is right
The solution is (5,2)
Step-by-step explanation:
From the third column the equation for sum of equivalent system is given as;
8x = 40
divide both sides by 8 to get value of x
8x/8 = 40/8
x=5
Using the value of x in the fifth column's first equation will be;
4x +4y =28
4(5) + 4y =28
20 +4y =28
4y= 28-20
4y=8
divide both sides by 4 to get y
4y/4 =8/4
y=2
The solution is x=5 and y=2 written as (5,2)

The computation shows that the time when they'll meet each other will be 175 minutes.
<h3>How to illustrate the information?</h3>
From the information, it takes the first student 25 minutes to complete one lap, and it takes the second student 35 minutes to complete one lap.
It should be noted that the time when they'll meet each other will be the lowest common multiple of 25 and 35.
This will be 175 minutes.
