Answer:
y= 20/7
Step-by-step explanation:
4-5y + -2y+16 = 0
20-7y = 0
-7y = -20
y= 20/7
Answer:
So 
will be equivalent to 
in radical form
Step-by-step explanation:
We have given expression
We have to write this in radical form
We know that if any fraction is in exponential form then if we write this in radical form then in radical form the exponent come inverse of its number
So can be written in radical form as
So will be equivalent to in radical form
Answer:
f(x) = 2x+5
Step-by-step explanation:
Given the arithmetic sequence shown
7,9, 11, 13, 15, 17,
THe nth term of the sequence is expressed as;
Tn = a + (n-1)d
a is the first term = 7
d is the common difference = 9-7 = 11-9 = 2
Substitute
Tn = 7 + (n -1)*2
Tn = 7 + 2n - 2
Tn = 2n + 5
Hence the required function is f(x) = 2x+5
It will take 36 days for 20 men to complete the building
Answer:
Yes
Step-by-step explanation:
6(-1-4)-30(-1) can be simplified into 6(-5)+30 which becomes -30+30, and then 0.
