Which system has no solutions? x < 3 x < 1 x > 3 x > 1 x < 3 x > 1 x > 3 x < 1

Answers

Answer 1

The system of inequalities with no solution is x > 3 x < 1

How to determine the system with no solutions?

The systems of inequalities are given as:

x < 3 x < 1

x > 3 x > 1

x < 3 x > 1

x > 3 x < 1

As a general rule, it is impossible for a variable to be greater than a higher number and less than a smaller number.

This means that if x is greater than 3, then it must be greater than 1

Hence, the system of inequalities with no solution is x > 3 x < 1

An elevator can hold a maximum of 1500 pounds. An average child weighs 75 pounds and the average adult weighs 150 pounds. The elevator also can’t fit more than 14 people. How many children and adults can fit in the elevator and stay under the weight limit. Write the inequalities that represent the word problem, and then graph it on DESMOS. What is a solution that represents the amount of children and adults and their combined weight?

Answers

Let's take this problem step-by-step:

Let's first set up some variables:

c: # of childrena: # of adults

Let's examine the information given:

Elevator can hold a maximum of 1500 pounds

          ⇒ average child is 75 pounds

          ⇒ average adult is 150 pounds

                 ⇒ therefore: [tex]75c + 150a\leq 1500[/tex]

Elevator can fit no more than 14 people

          ⇒ therefore: [tex]c + a \leq 14[/tex]

Let's graph the equations:

 [tex]75c+150a\leq 1500\\c+a\leq 14[/tex]

    ⇒ look at the image attached

The point at which the two graphs intersect:

  ⇒ is the solution that represents the amount of children and adults and

      their combine weight

With the horizontal axis being the # of children and vertical axis being the # of adults:

 ⇒ the solution is 8 children and 6 adults

Answer: 8 children and 6 adults

Here is the graph of a quadratic function f.

Answers

Answer:

B) x² - 8x + 12

E) (x -4)² - 4

F) (x - 2)(x - 6)

Explanation:

As the graph opens upwards. The value of x² will be positive.

The x intercepts are (2, 0), (6, 0) determining (x -2)(x-6)

The (x - 4)² - 4 determines the vertex of x = 4, y = -4

When simplified:

⇒ (x -2)(x-6)

⇒ x² - 2x -6x + 12

x² - 8x + 12

Step-by-step explanation:

Let the speed of the car is c and speed of the plane is p.

We are given:

The speed of the plane is 7 times the speed of the car

p = 7c

The distance traveled is

d = 315 km

The time difference to travel this same distance is 3 hours.

We know that:d = ts, where d- distance, t- time, s - speed

Find the time for car and plane and their difference.

Cart = d/s = 315/cPlanet = d/s = 315/p = 315/(7c) = 35/cThe difference315/c - 45/c = 3

Solve it for c:

(315 - 45)/c = 3270/c = 3c = 270/3c = 90 km/h

Now find the speed of plane:

p = 7c = 7*90 = 630 km/h

Thirty-one females are not attending the field trip. What percent of females are attending the class field trip?​

Answers

Answer:

79% of females are attending the class field trip

Step-by-step explanation:

Question Breakdown:

- Survey 271 students

- 121 males respond, 92 attending field trip

- 31 females not attending field trip

What percent of females are attending the class field trip?​

The two-way table or the class whether they are attending the field trip or not is attached below,

The table tells us

• Males who are not attending : 121 - 192 = 29

• Total females who responded : 271 - 121 = 150

• Females who are attending : 250 - 31 = 119

• Total students who are attending : 91 + 119 = 211

• Total students who are not attending : 29 +31 = 60

There are a total of 150 female students and 119 of them are attending the field trip

What is an exponential function?

An exponential function is modeled by:

[tex]A(t) = A(0)(1 \pm r)^t[/tex]

In which:

A(0) is the initial value.r is the rate of change, as a decimal.

For the first restaurant, we have that the parameters are given as follows:

A(0) = 3000, r = -0.015.

Hence the profit after x weeks is given by:

[tex]y_1(x) = 3000(0.985)^x[/tex]

For the second restaurant, we have that:
A(0) = 1500, r = 0.012.

Hence:

Then they will be equal when:
