Answer: If you think of the relationship between two quantities, you can think of this relationship in terms of an input/output machine. If there is only one output for every input, you have a function. If not, you have a relation. You can conclude that this set of ordered pairs does not represent a function

Classify the system of equations -1/2x=3-y -7+y=1/2x-2

miskamm [114]

Answer: Inconsistent.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

Solve for "y" in each equation:

<em>Equation 1</em>

$-\frac{1}{2}x=3-y\\\\y=\frac{1}{2}x+3$

<em>Equation 2</em>

<em> $-7+y=\frac{1}{2}x-2\\\\y=\frac{1}{2}x-2+7\\\\y=\frac{1}{2}x+5$ </em>

<em> </em>

You can notice that the slope of the <em>Equation 1 </em>is:

$m_1=\frac{1}{2}$

And the slope of the <em>Equation 2 </em>is:

$m_2=\frac{1}{2}$

Observev that $m_1=m_2$ , then you can conclude that the lines are parallel and the System of equations has No solution.

When there is no solution the classification of the system of equations is: "Inconsistent".

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,159 was collected on the sale of 1,339 ticket

ivolga24 [154]

Answer:

455 adult tickets
884 student tickets

Step-by-step explanation:

Let "a" represent the number of adult tickets sold. Then 1339-a is the number of student tickets sold. The revenue collected was ...

5a + 1(1339-a) = 3159

4a = 1820 . . . . . . subtract 1339, collect terms

a = 455 . . . . . . . . divide by 4; adult tickets sold

(1339-a) = 884 . . . . student tickets sold

455 adult tickets and 884 student tickets were sold.

<em><u>Answer: 10.</u></em>

<em><u /></em>

<em><u>Step-by-step explanation:</u></em>

<em><u>DIVISION. 120/12.</u></em>

<em><u>That is hard! Here's a trick.</u></em>

<em><u>12x9= 99=9=108. Or 12x6=66+6=72.</u></em>

<em><u>We will stick with 12x9, that equals 108.</u></em>

<em><u>We should add another 12 until we get to 120. </u></em>

<em><u>108+12=120. That is 10 times. The trick was...</u></em>

<em><u>dividing by 12 is hard, so lets say 12x4. I can put 4 and 4 together.</u></em>

<em><u>44 then and another 4. That is 48. So 12x4=48.</u></em>
