i'm 99% sure!
Answer: B. 2 = 3x + 10x2
Step-by-step explanation:
This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:
[-3+-sqrt(3^2+4(10)(2))]/(2(10))
The formual that was applied here was a quadratic formula given by:
x=[-b+\-sqrt(b^2-4ac)]/2a
whereby from the our substituted values above,
a=10,b=3 and c=-2
such that the quadratic equation will be:
10x^2+3x-2
All you have to do is x times 42 plus y times 42 and then you have to add the first day on which is 89.This is how it should look (x*42)+(y*42)+89.
Answer:
x = 3
Step-by-step explanation:
5x - 8 + 8 = 7 + 8
5x = 15
5x/5 = 15/5
15 divided by 5 equals 3
Hope this helped you out :)
