What is the expanded notation for 50

Find the slope of the line passing through the points (7, -1) and (2, -8).

Ugo [173]

Answer:

$\frac{4}{5}$

Step-by-step explanation:

We have to use the slope formula: m = slope

(x1, y1) = coordinates of the first point in the line

(x2, y2) = coordinates of the second point in the line

Here, we'll plug into our given points to give; $\frac{7--1}{2--8}$

Solving this, we get, $\frac{8}{10}$ , but we're not done, as this fraction can be reduced.

Diving both sides of the fraction by 2, we get our final answer of $\frac{4}{5}$ .

Wade was asked to solve this inequality:

frozen [14]

Answer:

The correct option is Option A: Yes, that is the correct step

Step-by-step explanation:

Wane was asked to solve the inequality $\large \frac{x}{3}\ge11$

He decides that he needs to multiply both sides by 3.

We need to tell if the step is correct?

So, solving the inequality

$\frac{x}{3}\ge11$

We need to multiply both sides by 3, to get value of x i.e.

$\frac{x}{3}*3\ge11*3\\x\geq 33$

So, Wanes step is correct.

The correct option is Option A: Yes, that is the correct step

The graph below shows a company's profit f(x), in dollars, depending on the price of pens x, in dollars, sold by the company:

Volgvan

The answers to the various part as well as its reasons are given below

The x-intercepts shows a zero profit.
The maximum value of the graph tells or depict the maximum profit.
The function is one that goes up or increases upward until it reach the vertex and then it falls or decreases after it.
This implies that the profit goes up as it reaches the peak at the vertex and it goes down after the vertex up until it gets to zero.
The profits are negative as seen on the left of the first zero and on the right of the second zero.

An approximate average rate of change of the graph from x = 3 to x = 5, shows the reduction in profit from 3 to 5.

Based on the above, the domain is one that is held back or constrained by x = 0 .

We are compelled at x = 6 due to the fact that we have to maneuver a negative profit.

The average number of customers per day increased 25 percent during the sale. If the average number of customers per day before

Rasek [7]

Answer:

The average number of customers per day during the sale was 150.

Step-by-step explanation:

This question can be solved using a rule of three.

Before the sale, the average number of customers per day was 120, which is 100% = 1.

Now, there are x customers, and since it is an increase of 25%, it is 100+25 = 125% = 1.25. So

120 - 1

x - 1.25

x = 1.25*120 = 150

The average number of customers per day during the sale was 150.
