Answer: 42-8x

Step-by-step explanation:

Hi, to answer this question we have to write and equation for each girl.

The money left that Jessica has is equal to the money she had (15) minus the product of the number of apples bought (3) and the cost per apple(x):

Mathematically speaking:

Jessica = 15-3x

Same process for Levi:

Levi =27-5x

Adding both expressions:

15-3x+27-5x

15+27-3x-5x

42-8x

Feel free to ask for more if needed or if you did not understand something.

Answer: 42 - 8x

Step-by-step explanation:

Here is the complete question:

Jessica had $15. She bought 3 apples for x dollars each. Levi had $27 and bought 5 apples for x dollars each. Which expression represents how much money both Jessica and Levi have left altogether?

Select one:

27 – 5x

42 – 8x

12 – 2x

39 – 3x

From the question, Jessica had $15. She bought 3 apples for x dollars each. This means she had:

15 - (3 × x) = 15 - 3x

Levi had $27 and bought 5 apples for x dollars each. Levi will have:

27 - (5 × x) = 27 - 5x

The amount they'll have altogether will be the addition of their amount left. This will be:

15 - 3x + 27 - 5x

= 15 + 27 - 3x - 5x

= 42 - 8x

The vertex of the graph of f(x) = |x - 3| +6 is located at<br> Done<br> Intro

Igoryamba

Answer:

The vertex of the graph is located at the point (3,6)

Step-by-step explanation:

Here, we want to know where the vertex of the equation if plotted will be

To get this, what we have to do is to equate the expression that we have in the absolute value to zero

After this, we then proceed to solve for the value of x

We have this as;

x -3 = 0

hence;

x = 0 + 3

x = 3

to get the y-value of the vertex, we look at the value at the side of the absolute value

This value is 6 and thus, the y-value of the vertex point is 6

So the coordinates of the vertex is (3,6)

Classify the limaçon represented by the equation r=(1/2)-(1/2)sin(theta)

babunello [35]

We know that

Limacons are in the form
r=a(+-)b*sin (theta) or r=a(+-)b*cos (theta)

in this problem
r=a(+-)b*sin (theta)
so
is symmetric to y axis
a=1/2
b=1/2
a/b=1---------> Cardioid (hearth shaped)

see the attached figure

the answer is the option
<span>A. Cardioid </span>
