Answer: True

One example would be f(x) = 3/(x-2). Here the 'a' value is a = 2.

Plugging x = 2 into f(x) leads to a division by zero error. Visually the graph will have a vertical asymptote through 2 on the x axis. The vertical asymptote is like an electric fence in which the graph slowly approaches but never touches or crosses.

Answer:

Option C

The student's conclusion is correct because the solution to the system of equations $3x+2y=27$ and $2x+y=16$ is $(5,6)$

Step-by-step explanation:

Let

x------> the cost of each burger

y-----> the cost of each sandwich

we know that

$3x+2y=27$ -----> equation A

$2x+y=(27-11)$

$2x+y=16$ ----> equation B

Solve the system of equations

Multiply the equation B by $-2$

$-2(2x+y)=-2*16$ -----> $-4x-2y=-32$ ------> equation C

Adds equation A and equation C

$3x+2y=27 \\-4x-2y=-32\\ ----------\\ 3x-4x=27-32\\ -x=-5\\x=5$

Substitute the value of x in the equation B

$2(5)+y=16$

$10+y=16$

$y=6$

The solution of the system of equations is the point $(5,6)$

The price of each burger is $\$5$

The price of each sandwich is $\$6$

Answer:

You have to multiply all the sides by 4.

B to C = 2.8*4

2.8 * 4 = 11.2

B to A = 3*4

3*4 = 12

A to C = 2.2*4

2.2*4 = 8.8

Hope this helped!

Ashley and Keely shared some Hershey Kisses in the ratio of 5:2. If Keely had 12 Hershey Kisses, how many did Ashley have?

wolverine [178]

Answer:

Ashely had 30 kisses! Muah!

Step-by-step explanation:

Ratio of Ashely to Keely is 5 : 2 and we know Keely had 12. Keely represents the 2 in this ratio, and how do we get from 2 to 12? We multiply by 6. We have to multiply by 6 on the other side too then. 5 times 6 is 30, so Ashely had 30 hershey kisses.

In real life, not in ratio form, Ashely had 30 kisses and Keely had 12.

Please mark brainliest if possible, have a nice day! :)
