We can use point slope form to solve for this.

y - 1 = -2(x - 2)
Simplify.
y - 1 = -2x + 4
Add 1 to both sides.
y = -2x + 5

Now, we can input -3 for x and solve for y, or r in this case.

y = -2(-3) + 5
y = 6 + 5
y = 11

r = 11

“ write all your answers with a positive exponent so your answer will be in the form of x^# or 1/(x^#)

gayaneshka [121]

Answer:

Step-by-step explanation:

5). $\frac{1}{x^{-9}}$ = $\frac{1}{\frac{1}{x^9} }$

= $x^{9}$

6). $\frac{1}{x^{-2}}=\frac{1}{\frac{1}{x^2} }$

= x²

7). $x^{-6}=\frac{1}{x^6}$

8). $\frac{1}{x^{-7}}=\frac{1}{\frac{1}{x^7} }$

= $x^{7}$

9). $x^{-8}=\frac{1}{x^8}$

10). $\frac{1}{x^{-3}}$ = $\frac{1}{\frac{1}{x^{3}}}$

= x³

Let 'a' represent the number of adult tickets sold. Then total revenue was ...

9.60a +5.80(167 -a) = 1322

3.80a = 353.40 . . . . . . . . . . subtract 968.60, collect terms

a = 93 . . . . . . . . . . divide by 3.8

93 adult tickets were sold that day.
