Select the system of linear inequalities whose solution is graphed.

igor_vitrenko [27]

Answer:

y ≤ x + 1; y ≤ 1

Step-by-step explanation:

The horizontal line has the form y = b. Since it is an inequality with a solid line, it will be y ≥ b or y ≤ b. Here b is the y-intercept which is 1. So the equation is y≤1 or y≥ 1.

The solid diagonal line has a y-intercept at 1 and a slope of 1. So the equation is y ≥ x + 1 or y ≤ x + 1.

The solution which has the right combination is y ≤ x + 1; y ≤ 1.

You randomly choose one of the following numbers shown. Find the probability the event can occur choosing a number greater than

sergey [27]

<h3>Answer: 7/11</h3>

======================================================

Explanation:

The event space is the set of outcomes we want to happen.

The event space is {5, 6, 7, 8, 9, 10, 11} which consists of getting a value greater than 4. There are 7 items in this event space. Let A = 7.

The sample space consists of all possible outcomes. The sample space is {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} and there are 11 items in the sample space. Let B = 11.

Divide the values of A and B to get the answer we're after

A/B = 7/11

This is the probability of selecting a value greater than 4.

Christie sells lemonade in her driveway she spends $20 dollars on supplies lemons sugar and cups she can make enough lemonade fo

Rasek [7]

Answer:

Profit = $ 5

Step-by-step explanation:

Money spent on supplies = $ 20

Number of cups of lemonade sold by her = 100

Selling price for 1 cup of lemonade = 1 quarter = $ 0.25

∴ Selling price for 100 cups of lemonade = $0.25\times100=25$

So, Christie can make $ 25 from 100 cups of lemonade.

Profit made by her = Selling price - Money spent on supplied

= $ 25 - $ 20 = $ 5.

If y varies directly as x, and y is 6 when x is 72, what is the value of y when x is 8

Xelga [282]

Answer:

Y varies directly as X.

y=kx.

6=K72.

x=6/72.

x=0.08.

Y=0.08x.

when y=?, x=8.

y=0.08×8=0.64.
