Answer:
You just have to combine terms
Step-by-step explanation:
10h + 6 - 5h +3 can be written as:
10h - 5h + 3 + 6 (now all you have to do is combine terms)
<u>5h + 9</u>
Answer:
We conclude that the function represents exponential growth.
Step-by-step explanation:
Given the function
As the function is of the form
and base 'b' > 1
We know that when the base 'b' of the exponential function > 1, meaning those numbers will get bigger, we call it exponential growth.
As b=8/5 is bigger than 1.
i.e. 8/5 > 1
Thus, we conclude that the function represents exponential growth.
Answer:
Domain = R- {0,4}
Step-by-step explanation:
In order to function (f*g)x to be defined , the Denominator must not be equal to zero.
Hence
x ≠ 0
(x-4) ≠ 0 ⇒ x≠4
Hence (f*g)x is defined for all values of x except 0 and 4
Hence Domain = R- {0,4}
Answer: y = -5x + 20
Step-by-step explanation:
Remember that : y=mx+b
y = (-5)x + b
Now you can plug your coordinates (-7,8) into that equation.
8 = (-5)-7 + b
Solve for b
8 = -12 + b
Add +12 to both sides of your equation:
20 = b
Now, your new equation is:
y = -5x + 20
