Answer: linear function is 25x + 20
After 8 weeks he has saved 25(8)+20 which is 200, so he saved $200 after 8 weeks.
Step-by-step explanation:
Ok so we say 25x because x is any amount of weeks he has saved for and because he had a head start of $20, we add 20 when calculating after any amount of weeks( because even if we know he saved 25x after x weeks we have to add the 20 dollars he also started with)
I hope this helps:)
A) The two angles are supplementary and form a linear pair. This means that their combined measure is 180 degrees.
B) 2x + 68 = 180
C) subtract 68 from both sides. 2x = 112. Divide both sides by 2. x = 56.
If we plug 56 back into the equation 2x, we get 112. The if we add 112+68 we get 180, which means that the two are a linear pair.

3-1/2=k/2
3-1/2=2.5
2/ k=2.5
2.5 x 2=5
k=5
Step-by-step explanation:
15/100 = 12/x
Cross multiply 12 with 100, then divide by 15
1200/15
80 is your answer.
