Step-by-step explanation:
Hey there!!
During evaluating the expression, you must follow,
- put the value as given.
- work according to the mathematical operation sign.
Here,
= 30+36
= 66.
ii). b-4c
= 30 - 4×6
= 30 - 24
= 6

Answer:
see the explanation
Step-by-step explanation:
we know that
The equation of a exponential growth function is given by
where
a is the initial value or y-intercept
b is the factor growth (b>0)
In this problem
a=1
so
we know that
The graph of the function has no x-intercept
Remember that the x-intercept of a function is the value of x when the value of the function is equal to zero
That means ----> The output of the function can NEVER be equal to zero
<u><em>Verify</em></u>
For f(x)=0
Apply log both sides
Remember that
log 0 is undefined. It's not a real number, because you can never get zero by raising anything to the power of anything else.
Answer:
Equation of line:
Step-by-step explanation:
We have given,
Slope of line =
y intercept equal to that of a line y =
i.e, y intercept = -2 {Plug x = 0 in the line equation}
Hence we have a slope = and y intercept = -2.
That means , equation of line will be formed as:
And we can also plot this line on a graph.
Answer:
The required inequality is .
Jhon can buy at most 5 books.
Step-by-step explanation:
Consider the provided information.
Part(A)
Let b represent the number of books John buys.
He wants at least $10 in his savings account which means if we subtract the cost of books from $40 we have at least $10 left.
The required inequality is .
Part(B)
Part(C): Jhon can buy at most 5 books.
