Answer:

Jane's friend's assumption about the original price was incorrect.

Step-by-step explanation:

A price of $40 after being given a 20% discount would end up being $50 instead of $48. This is because 20% of $50 is $10, and that is what was deducted from the price to make it $40.

Hope I helped! ☺

Answer:

she is incorrect because if she was given a 20% discount the amount she would have to pay is 38.4

Step-by-step explanation:

48 x .2 = 9.6

48 - 9.6 = 38.4 not 40

Which of the following rational functions is graphed below?
IrinaVladis [17]

Answer:

Option (D)

Step-by-step explanation:

The given graph represents a rational function having,

1). Vertical asymptote → x = 2

2). Horizontal asymptote → y = 0

Parent function representing the rational function will be in the form of,

F(x) = \frac{1}{x^{2} }

Since, vertical asymptote of the function is x = 2, denominator of the function will be in the form of (x - 2)².

Since, horizontal asymptote of the function is y = 0, highest exponent term in the numerator will be 0.

Therefore, numerator of the fraction will be x⁰.

The rational function given in the graph will be,

F(x) = \frac{x^{0}}{(x-2)^2}

F(x) = \frac{1}{(x-2)^2}

Option (D) will be the answer.

Can someone answer this for me
ladessa [460]

The linear equation in standard form is:

6x - 7y = -11

Which is the last option.

<h3>How to get the equation of the line?</h3>

The line in slope-intercept form is written as:

y = a*x + b

We can see that the line passes through the points (-3, -1) and (1/2, 2), then the slope is:

a = \frac{2 - (-1)}{1/2 - (-3)}  = \frac{3}{3.5}  = \frac{6}{7}

Then we can write:

y = (6/7)*x + b

To find the value of b, we use the first point. It means that when x = -3, the value of y is -1, then we get:

-1 = (6/7)*-3 + b

-1 + 18/7 = b

-7/7 + 18/7 = b

11/7 = b

Then the equation is:

y = (6/7)*x + 11/7

If we multiply both sides by 7 we get:

7y = 6x + 11

Now we move the term with "x" to the left:

7y - 6x = 11

That is the line in standard form.

If we multiply both sides by -1, we get the last option:

6x - 7y = -11
