Answer:
Look at explanation i wasn't too good at this but i could get this far otherwise i didn't know what to do!
Step-by-step explanation:
6 x 2x = 12x 6 x y= 6y
12x+6y + 2x+4y
12x+2x= 14x
4y+6y= 10y
14x+10y
The upper one is correct. Because 0,75% = 0,0075 ( :10) and since the interest rate is positive it has to be 1 + ...
Answer:
It is a linear function because there is a constant rate of change in both the input and output values
Step-by-step explanation:
To determine if the function is linear, calculate the differences between the y values.
If the differences are constant, or the same value, the equation is linear and has a constant slope. If the differences are not the same, the equation is not linear.
<u>difference between y values (output)</u>
7 - 4 = 3
3 - 1 = 3
1 - -2 = 3
⇒ the function is linear
<u>difference between x values (input)</u>
-2 - -5 = 3
-5 - -8 = 3
-8 - -11 = 3
⇒ the function is linear as there is a constant rate of change in both the input and output values
