Answer:

Ashley should have added 4.5 to both sides.

Step-by-step explanation:

Given expression:

-4.5+m=17

Ashley's solution:

Subtracted 4.5 to both sides and got,

m=12.5

Correct solution:

Adding 4.5 to both sides.

-4.5+m=17

 +4.5          +4.5

∴ m=21.5

Error made by Ashley was subtracting 4.5 both sides. Instead he should have added 4.5 both sides.

Which function has an asymptote at x= 39
LekaFEV [45]

Answer:

option B : f(x)= log_7(x-39)

Step-by-step explanation:

(a) f(x) = 7^{x-39}

For exponential function , there is no vertical asymptotes

General form of exponential function is

f(x) = n^{ax-b}+k

f(x) = 7^{x-39}

In the given f(x) the value of k =0

So horizontal asymptote is y=0

(b) lets check with option

f(x)= log_7(x-39)

To find vertical asymptote we set the argument of log =0  and solve for x

Argument of log is x-39

x-39=0 so x=39

Hence vertical asymptote at x=39

Solve and graph each of the following inequalities for x.
Ulleksa [173]

2x + 4 > 8

Step 1: Subtract 4 from both sides.

2x + 4 − 4 > 8 − 4

2x > 4

Step 2: Divide both sides by 2.

2x/2  >  4/2

x > 2

2x − 3 < 5

Step 1: Add 3 to both sides.

2x − 3 + 3 < 5 + 3

2x < 8

Step 2: Divide both sides by 2.

2x/2  <  8/2

x < 4
