Answer:
Diego would need to sell 80 tickets.
Step-by-step explanation:
Divide 140 by 1.75 to get your answer. To double-check multiply 1.75 by 80, and you should get 140.
Note that when x increases by 1, y increases by 4. Thus, the slope of the linear function representing this table is 4. What is the y-intercept? Note that as y decreases by 4, x decreases by 1. We have y = 1 and want the y-intercept, (0,y). Start with y=1 and subtract 4; the result is -3. So the y-intercept is (0,-3):
y = 4x - 3 (answer)
The answer which is not listed but it is 2 dollars per pen
Answer:
There are 111 blue bags
Step-by-step explanation:
Let
x ----> the number of black bags
y ---> the number of blue bags
we know that

isolate the variable y
-----> equation A
----> equation B
substitute equation B in equation A
therefore
There are 111 blue bags
The answer is c. 7•2= 14, then 7+7= 14+2= 16+2= 18
