Answer:
The third and the forth
Step-by-step explanation:
Functions do not have repetition in the x column.
Since the other options have doubles of an x value
(or, to phrase it differently, two y values for one x value)
they are not functions.
$50
$15 + $35 (5 weeks) = $50
$35 + $15 (5 weeks) = $50
Answer:
y = 5x + 4
Step-by-step explanation:
First I found the slope by using the the definition that slope is rise/run so I saw that the y value went up from 4 to 9 which is 5 units and then the x value went up one in that same time. This means that the slope is 5/1. Then I found the y intercept by seeing where x = 0. On the graph you can see the line touches the y - axis at a value of 4 which means that the y - intercept is 4. Plugging these values into the y = mx + b equation you get y = 5x + 4.
The three numbers have to multiply to 48 in a ratio of 3:2:1
which would be 6:4:2
so 6 inches
