Answer:
x=-2
y=-8
Step-by-step explanation:
13x-6y=22
x=y+6
13x-6y=22
x-y=6
13x-6y=22
-6x+6y=-36 (multiplied by -6)
(13-6)x+(-6+6)y=22-36
7x=-14
x=-2
x=y+6
-2=y+6
y=-8
Answer:
oki! Mizuki is here to help!
The answer is 61 cars!
Step-by-step explanation:
<em>First, let's find how much money she needs to earn!</em>
105 + 500 = 605
<em>Then, we will divide the amount she needs to earn by the amount per each car!</em>
605 ÷ 10 = 60.5
<em>We get 60.5 As an answer but... since we must wash a whole car, we will round it up and get 61 cars as the answer!</em>
The vertical asymptote of f(x) is (A) x = 0, –9.

What is a function?</h3>
- A function is an expression, rule, or law in mathematics that describes a relationship between one variable (the independent variable) and another variable (the dependent variable).
- Functions are common in mathematics and are required for the formulation of physical relationships in the sciences.
To find the vertical asymptote of f(x):
The vertical asymptotes of a function are the zeroes of the denominator of a rational function
The function is given as:
Set the denominator to 0:
Factor out x:
Express 81 as 9^2:
Express the difference between the two squares:
Split, or or .
Solve for x:
Therefore, the vertical asymptote of f(x) is (A) x = 0, –9.
(See attachment for the graph of f(x))
