Answer:
(-∞,7) U (7,∞)
Step-by-step explanation:
f(x)= x+2
g(x) = x-7

Here we have x-7 in the denominator
To find domain we set the denominator =0 and solve for x
x-7=0
Add 7 on both sides
x=7
x=7 makes the denominator 0 that is undefined
So we ignore 7 for x
Hence domain is
(-∞,7) U (7,∞)
Answer:
divide the interest amount by the product of the principal and time
Step-by-step explanation:
The simple interest formula is I = prt where I is the interest, p is the principal, r is the rate and t is the time (in years). Rewriting this formula so that r is the subject we get r = I / pt. Therefore the answer is divide the interest amount by the product of the principal and time.
It can save time from doing number crunching and analysis because it's an easy to see visual.
Answer:
x=-3+√19, x=-3-√19
Step-by-step explanation:
x^2+6x=10
x^2+6x-10=10-10
x^2+6x-10=0
a=1 b=6 c=-10 - use the quadratic formula
x=-3+√19, x=-3-√19
I hope this helps!
