Answer:
3.2?? I am kinda confused
Step-by-step explanation:
This is a quadratic equation with a general equation of ax^2 + bx + c.
The quadratic formula can help to get the roots of the equation. We know the highest degree of that equation is 2; so there will be also two roots.
The quadratic formula is
x = [-b ± √(b^2 - 4ac)] / 2a
With a = 1, b = 7, c = 2,
x = {-7 ± √[(7)^2 - 4(1)(2)]} / 2(1) = (-7 ± √41) / 2
So the two roots are
x1 = (-7 + √41) / 2 = -0.2984
x2 = (-7 - √41) / 2 = 0.2984
This is also another way of factorizing the equation
(x + 0.2984)(x + 0.2984) = x^2 + 7x + 2
Answer:
General Equation of a Line

Step-by-step explanation:
Find the slope first and then place the values on the general formula. The final step is to solve for y
Answer:
$1500
Step-by-step explanation:
you can figure it out by going in increments of 4.5 years because that is the info you have from the problem so
47000 4.5 years later is 23500
9 years = 11750
13.5y = 5875
18y = 2937.5
22.5 years later is 1468.75
22.5 years is about 23 years and to the nearest hundred dollars that is $1500 so that is the answer
Hope this helps! :)
