Solved the inequality incorrectly and graphed their solution incorrectly.
Solved the inequality correctly but graphed their solution incorrectly.
Solved the inequality incorrectly but graphed their solution correctly.
Solved the inequality correctly and graphed their solution correctly.

Answers

Answer:

solved the solution incorrectly and graphic their solution correctly.

Step-by-step explanation:

this is because if 4x + 1<= -4

the next step will be to subtract 1 from both sides.

BUT if their solution is x<= 2, they objectively graphed it correctly

Step-by-step explanation:

4x+1 < -4

-1 -1

--------------

4x < -5

[tex]x \leqslant \frac{ - 5}{4} [/tex]

-5/4 is not 2, so both of them are wrong (1 is right choice)

The sophmore class at south high school raised $800 from ticket sales for the dance. Tickets sold for $1.50 pre - sale, and $2.00 at the door. If a total of 475 tickets were sold how many tickets were sold at the door?

Answers

Answer:

So they sold 300 tickets in advance and 175 tickets at the door.

Step-by-step explanation:

Answer:

175 tickets were sold at the door.

Step-by-step explanation:

Let x = number of pre-sale tickets.

Let y = number of tickets sold at the door.

Equation for total number of tickets:

x + y = 475

Equation of total price of tickets:

1.5x + 2y = 800

System of equations:

x + y = 475

1.5x + 2y = 800

Solve the first equation for x:

x = 475 - y

Substitute into second equation.

1.5(475 - y) + 2y = 800

712.5 - 1.5y + 2y = 800

0.5y = 87.5

y = 175

Answer: 175 tickets were sold at the door.

Find the function value: f(0.5) if f(x) = 8x - 12

Answers

x = 1.6

f = 0.5

0.5(x) = 8x -12

0.5x= 8x -12

subtract 8x from both sides

-7.5x = -12x

Divide by -7.5x, both sides

X=1.6
