Answer: What Is a Constant Function?
A constant function is a function having the same range for different values of the domain. Graphically a constant function is a straight line, which is parallel to the x-axis. The domain of the function is the x-value and is represented on the x-axis, and the range of the function is y or f(x) which is marked with reference to the y-axis.

Answer:
The expression is (80w+300)
Step-by-step explanation:
Let
y ----> the total amount of money in both accounts
s ----> the amount of money in saving account
c ----> the amount of money in checking account
w ----> the number of weeks
we know that
saving account
s=50w+200 -----> equation A
checking account
c=30w+100 ----> equation B
To find out the total amount of money in both accounts, sum equation A and equation B
y=s+c
substitute
y=(50w+200)+(30w+100)
y=(50w+30w)+(200+100)
y=80w+300
therefore
The expression is (80w+300)
Answer:
5x - 1
Step-by-step explanation:
(f + g)(x) = f(x) + g(x), thus
f(x) + g(x)
= 3x - 2 + 2x + 1 ← collect like terms
= 5x - 1
Answer:
13.5 minutes
Step-by-step explanation:
Cross multiply
3 × 576 = 128x
3 × 576 = 1,728
1,728 = 128x
1,728 ÷ 128 = x
13.5 = x
Answer:
y=-7x+47
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=-7(x-8)
y+9=-7(x-8)
y=-7x+56-9
y=-7x+47
