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
You would do
(1.1)(80,000,000)=88,000,000
That is the total cars for year two. To find the increase you would do
(1.1)(88,000,000)=96,800,000
Then you would subtract year 2 from year three
96,800,000-88,000,00=8,800,000
That gives you ur answer.
Answer:
B. y = 2x
Step-by-step explanation:
every y value is the value of x multiplied by 2
so that means y=2x
hope this helps luv <3
Answer:
x² + (y + 8)² = 81
Step-by-step explanation:
Centre (h,k) = (0,-8)
radius (r) = 9
(x - h)² + (y - k)² = r²
(x - 0)² + (y + 8)² = 9²
x² + (y + 8)² = 81
I’m not sure? But don’t answer the guy with the bitly it’s a scam
