7/10 - 1/4 use common denominators
28/40 - 10/40 = 18/40 = 9/20
Answer:
A option
Step-by-step explanation:
50 miles = 1 hour
10 miles = 1/50 x 10
= 1/5 hours
= 12 minutes
It will take him 12 minutes to drive 10 miles.
How many zeros does the function f(x) = 3x12 − 17x8 + 11x4 − 6x + 23 have?
Answer: the third option (12 zeros..).
Use ^ to denote an exponent..
f(x) = 3x^12 - 17x^8 + 11x^4 - 6x + 23..
We know from that fact that the number of zeros (real or complex) in a polynomial is the same as the degree of the polynomial..
The degree is the greatest/highest power of the terms, which in this case is 12 (since 12 is the greatest exponent..)..
The degree is 12, thus it means there are 12 zero's..
Answer: the third option (12 zero's )...
Answer:
no solution
Step-by-step explanation:
Given the 2 equations
y = 
x + 4 → (1)
- x + y = - 5 → (2)
Substitute y = x + 4 into (2)
- x + x + 4 = - 5 , that is
4 = - 5 ← not possible
This indicates the system has no solution
