Answer:
Step-by-step explanation:
The slope-intercept form is given by:
where m is the slope and b is the y-intercept or initial value.
Here, c(m) represents the cost of bill c in terms of m and m represents the number of minutes.
As per the statement:
Bill bought a new cellular phone. his monthly bill will be $34.99 each month which includes 100 minutes of use.
⇒
It is also given that additional minutes will cost $0.23 per minute.
⇒For additional minutes, he will cost per minute = $0.23
for m minutes, he will cost $0.23 m
Using the point slope intercept form we have;
Therefore, an equation that represents the cost of the bill used above the 100 that are included in the base price is:
We can follow the following steps to make an equation and solve it.
Step 1:
five less than 13 means we have to subtract 5 from 13
so it becomes 13-5
Step 2:
A number y is five less than thirteen.
Now in algebraic expressions, "is" stands for "="
So we have:
Step 3:
Solving the equation to find y.
Subtracting 5 from 13, we get :
y=8
Answer:
For the given equation the solution is y=8.
Answer:
Step-by-step explanation:
we know that
The lateral area of the cone is equal to
where
r is the radius of the base
l is the slant height
we have
Applying the Pythagoras Theorem find the slant height
substitute in the formula
