I dont understand how to simplify an expression with exponents
Mashutka [201]

Answer:

3^4

Simplifying an expression with expression with exponents:

If they are dividing, we keep the base and subtract the exponents. For example:

\frac{a^x}{a^y}=a^{x-y}

In this question:

\frac{3^2}{3^{-2}}=3^{2-(-2)}=3^{2+2}=3^4

What is the equation of the line containing the points (3, 1), (9, 3), and (27, 9)?
lutik1710 [3]

From the given points that are (3,1),(9,3),(27,9), we can say that x is three times of y. That is

x= 3y

And we need to solve for y. For that, we need to get rid of 3 from the right side by dividing both sides by 3 . And on doing so , we will get

\frac{x}{3} = \frac{3y}{3}

\frac{x}{3}=y

or

y=\frac{x}{3}

Connor spent $66 on rookie cards and Hall of Fame cards how many of each type of car did he buy rookie cards are four for six Ha
barxatty [35]

Answer:

We conclude that he purchased 20  rookie cards and 8  Hall of Fame cards.

Step-by-step explanation:

We know that Connor spent $66 on rookie cards and Hall of Fame cards. We know that rookie cards are four for six Hall of Fame two for nine.

Therefore, we calculate:

5\cdot 6 +4\cdot 9=30+36=66

5·4= 20 rookie cards

4·2= 8 Hall of Fame cards

We conclude that he purchased 20  rookie cards and 8  Hall of Fame cards.
