The given percent above is 215%. To convert this into decimal, let us divide this by 100. 215 / 100 and we get 2.15. So the decimal form of 215% is 2.15. Next, convert it into a fraction. Given the decimal form of 2.15, this is already equivalent to 2 15/100. To simplify this, since both 15 and 100 are divisible by 5, we get 3/20. Therefore, the fraction is 2 3/20. So the correct answer is option B. 2.15; 2 3/20.
Answer: i think it's either a or d
Answer:
The third choice.
Step-by-step explanation:
This is a linear function.
The equation is y = (x - 5)(5x + 4) - 5x^2.
y = 5x^2 - 25x + 4x - 20 - 5x^2
y = 5x^2 - 5x^2 - 21x - 20
y = -21x - 20
That means this is a linear function, with a linear term of -21x and constant term of -20.
Hope this helps!
The best approximation for the solution to this system of equations is (-2.2,-3)
Option C is correct.
Step-by-step explanation:
Solving the system of equations to get the exact value of x:
Let
Putting value of y from eq(1) into eq(2)
So, Value of x is -2.2
The best approximation for the solution to this system of equations is:
x=-2.2 and y = -3
(-2.2,-3)
Option C is correct.
