Hello,
With
y=x²-4x-21
y=-5x-22
==>x²-4x-21=-5x-22
==>x²+x+1=0
In R, no solution for Δ=1-4=-3<0
Answer:
24,950.
Step-by-step explanation:
You can use the arithmetic series formula (a sequence is the list of numbers; a series is the summation of the list).
To find the sum...
(100 / 2) (2 * 2 + (100 - 1)5) = 50 * (4 + 99 * 5) = 50 * (4 + 495) = 50 * 499 = 24950.
Hope this helps!
After solving the equation we get y=2 when x = 15
Step-by-step explanation:
We need to complete the solution of the equation 
We need to find value of y when x equals -15
For finding value of y, we will put value of x= -15 in the given equation:



Adding -15 on both sides


Divide both sides by -8

So, After solving the equation we get y=2 when x = 15
