Answer:
Option (1) ; y = 7x
Step-by-step explanation:
(1) reads y = 7x, a line with slope 7, therefore the rate of change in this is 7
(2) says that y increases 12 units every time that x increases 4 Then the rate of change is: (increase in y / increase in x = 12/4 =3
(3) shows a table from which we can see that an increase of y in 8 corresponds to an increase of x in 2: rate of change = (8 - 0) , (2 - 0) = 4
(4) shos a line with slope (rate of change) given by: (12 - 0) / (2 - 0) = 12/2 = 6
Therefore, the greatest rate of change is shown by the first expression
y = 7 x

I know my MATH mark me brainliest pls
Answer:
0.166
Step-by-step explanation:
Bought 18 cards for $2.99, so you can write it like this:
18 = 2.99
Since you want to find the value of one card, u could write that like this:
1 = x (where x is the unknown value of 1 card)
To get from 18 to 1, you divide by 18, so to get to 2.99 to x you must divide by 18 as well.
So 2.99/18 = 0.166
therefore x = 0.166
So you can say that each card costs about 17 c
Answer:
(-2,2)
Step-by-step explanation:
Answer:
114.89 degrees
245.11 degrees
Step-by-step explanation:
cos is negative in the second and third quadrant ("pointing" on the x-axis to the left).
so, the first answer for the second quadrant is
114.89 degrees.
the answer for the third quadrant is then backwards the same angles from a full 360 degree rotation
360 - 114.89 = 245.11 degrees
