1. Which two points fail the VLT here in this graph? PLEASE HELP!!!!

PLEASE HELP why isnt 3,4 , 5,10 ,3,12 a function

myrzilka [38]

Functions have one output for every input. So that means one x-coordinate for one y-coordinate. In this case, (3,4) and (3,12) have the same x-coordinate, so it can't be a function.

Solve using a system of equations. Tickets to a local movie were sold at $6.00 for adults and $4.50 for students. If 110 tickets

Marrrta [24]

Answer:

The number of adults tickets is 80 and the number of students tickets is 30

Step-by-step explanation:

Given as :

The tickets price for adults = $6.00

The tickets price for students = $4.50

Total number tickets were sold = 110

Total Price of 110 tickets = $615.00

Now,

Let The number of adults tickets sold = A

The number of students tickets sold = S

So, according to question

A + S = 110

And 6 A + 4.5 S = 615

Or, 6 A + 6 S = 660 .....1

6 A + 4.5 S = 615 ......2

Solving the equations

( 6 A + 6 S ) - ( 6 A + 4.5 S ) = 660 - 615

Or, ( 6 A - 6 A ) ( 6 S - 4.5 S ) = 45

or, ( 6 S - 4.5 S ) = 45

or, 1.5 S = 45

∴ S = $\frac{45}{1.5}$

I,e S = 30

Put the value of S in eq 1

So, 6 A + 6 × 30 = 660

Or, 6 A = 660 - 180

Or 6 A = 480

∴ A = $\frac{480}{6}$

I.e A = 80

Hence The number of adults tickets is 80 and the number of students tickets is 30 . Answer

0.75h + 3 = 12 What's the answer?

kykrilka [37]

Answer:

h = 12

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define equation

0.75h + 3 = 12

Step 2: Solve for h

Subtract 3 on both sides: 0.75h = 9
Divide 0.75 on both sides: h = 12

Step 3: Check

Plug in h into the original equation to verify it's a solution.

Substitute in h: 0.75(12) + 3 = 12
Multiply: 9 + 3 = 12
Add: 12 = 12

Here we see that 12 does indeed equal 12.

∴ h = 12 is a solution of the equation.

Hat is the metric system prefix for the quantity 0.000 001?

mezya [45]

In the metric system, you give a name to the following multiples: 10, 100, 1000, 0.1, 0.01, 0.001, and then you skip three places. So, you have

$\left.\begin{array}{cc}\vdots&\vdots\\1000000&\text{mega}\\1000&\text{kilo}\\100&\text{hecto}\\10&\text{deca}\\0.1&\text{deci}\\0.01&\text{centi}\\0.001&\text{milli}\\0.000001&\text{micro}\\\vdots&\vdots\\\end{array}\right.$

And thus 0.000001 of something is a micro-something (i.e. one millionth of a certain unit)
