Determine if the relation is a FUNCTION
Explain the reasoning for your response.
Function or not: 1/2 Point
Reasoning: 1/2 Point
Answers
Answer:
Step-by-step explanation:
Not a function. To be a function, it must pass the vertical line test. The x axis can only be used once. You can have more than one Y, but not the X. In this case, the -2(assuming it-2 by going over 2 places to the left) is used more than once.

Answers
Answer:
218
Step-by-step explanation:
this is ratio.
5+4=9. which is the ratio you add it.
5/9×360=200
therefore the number of boys in school during 2013 january is 200 plus admitted boys in February is 200+18=218.
therefore the number of boys in school from january to february is 218.

1)The price of a pair of boot was reduced from $80 to $60. By what percentage
was the price of the boots reduced?
2)Lisa and her date spent $87.70. They want to leave a 20% tip what amount would be reasonable for the tip
Answers
Answer:
1) 25%
2) $17.54
Step-by-step explanation:
1) The boots were reduced from $80 to $60, therefore the total amount they were reduced by in terms of money is $20. To find out what percentage $20 is of $80, you divide.
20/80 = 0.25
0.25 = 25 % (to change a decimal to a percentage, you multiply by 100)
2) 20% = 0.20 (to change a percentage to a decimal, you divide by 100)
To find 20% of $87.70, multiply 0.20 by 87.70.
87.70 x 0.20 = 17.54

PLS ANSWER ASAP! Determine the slope and y-intercept for the equation below.
Answers
Answer:Y-intercept = -3. Slope= 1/2
Step-by-step explanation:
Answer:
Slope= 1/2x
Y-intercept= -3
Step-by-step explanation:
The slope intercept form is defined as y = mx + b
Where m = slope (or change in y-coordinate/ change in x-coordinate)
and b = y-intercept (or where the graph crosses the y-axis)
In this particular equation... The slope (1/2x) represents a vertical change of 1 unit for every 2 units changed horizontally
It is also important to note that the negative stays with the 3 when defining b.
Therefore... the slope is 1/2x and the y-intercept is -3

Graph the line that represents this equation: y+2=1/2(x+2)
Answers
Answer:
x=2y+2
Step-by-step explanation:
ur welcome
Answer:
y = 1/2x - 1
Step-by-step explanation:
This formula is currently written in point-slope form (y+ + y1 = m (x + x1). To graph it easier, the first thing you would do is make it slope-intercept form (y=mx + b).
First, distribute the 1/2 into the parenthesis.
1/2(x+2)
1/2x + 1
Then, the equation should look like this: y+2 = 1/2x + 1
The next step is to subtract the 2 from both sides.
It should look like this:
y = 1/2x -1
Graph it by first plotting the y-intercept, -1, on the y-axis, and counting up 1 space and to the right 2 spaces, then drawing a line. I hope this helped!
