Answer with Step-by-step explanation:
We are given that

x=-1
Using property of limit

=
=
=



Hence, the function is continuous at x=-1
Answer:
-6
Step-by-step explanation:
1) distribute: 7x+28+6x-18=8x-24-2x+8
2)combine like-terms: 13x+10=6x-32
3)move the variable to one side: 7x+10=-32
4)subtract 10 from both sides: 7x=-42
5) divide each side by 7: x=-6
It will take 4 year for the account to reach $5,500.
<h3>How to find the amount?</h3>
The formula we use to calculate the amount is
A = P(1+r)¹
Where, P= amount of money invested
r = interest rate percentage in decimal form
t = time in years
A = total money in the account at time
Tina wants to save money for school.
Tina invests $400 in an account that pays an interest rate of 8%.
A = P(1+r)¹
5500 = 400(( 1 + 0.08)^t
5500/ 400 = ( 1 + 0.08)^t
55/ 4 = (1.08)^t
13.75 = (1.08)^t
t = 4

Answer:
A, all real numbers
Step-by-step explanation:
The domain is the x value and the x value is the domain.
So when you take a look at the x values, it keeps going on and on
So when x values or y values keep going on forever we call that all real numbers

The equation of a line is y=mx+b
To find the gradient you calculate the change in Y/change in X.
To find the y-intercept you should plug it in a graphic calculator.
