N = 2s/a+1 you wrote h but you didn’t actually write an h in the formula so I assume you meant n

Answer:

Step-by-step explanation:

$S = \frac{n}{2} (a+l)\\2s = h(a+l)\\2s = ha +hl\\\frac{2s}{a+l} = h+h\\2h = \frac{2s}{a+l}\\h = (\frac{2s}{a+l})/2\\h = \frac{2s}{2a+2l}$

To Make h subject of the formula

Step 1

: Cross multiply

Step 2 :

Use h to open the bracket

Step 3 :

Divide both sides by a +l to make h on one side of the equation

Step 4 :

Evaluate h+h = 2h

Divide both sides of the equation by 2

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

Is there a proportional relationship between x and y? Explain.

I don’t think so but divide the top one by the bottom one for every one of them and if it is all the same answer they are proportional x/y

Which graph represents y=-2x

seraphim [82]

A graph which represents the linear function y = -2x is: graph B.

<h3>What is a graph?</h3>

In Mathematics, a graph can be defined as a type of chart that is typically used for the graphical representation of data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis respectively.

Generally speaking, the graph of any proportional relationship is characterized by a straight line with the data points passing through the origin (0, 0) because as the values on the x-axis (x-coordinate) either increases or decreases, the values on the y-axis (y-coordinate) increases or decreases simultaneously.

In this context, we can reasonably infer and logically deduce that the relationship between x-values and y-values in the graph of y = -2x is proportional as it passes through the origin (0, 0).
