Answer:
Month 5 the cost will be the same
Step-by-step explanation:
Make to equations from the given information
Let y be the cost, and let x be the number of months
Club A: y = 25x + 100
Club B: y = 20x + 200
It wants to know when the cost will be the same, so set the 2 equations equal to each other and solve..
25x + 100 = 20x + 200
5x = 100 (subtract 20x and 100 from both sides)
x = 20 (divide both sides by 5)
So after 5 months the cost will be equal,
Answer:
Step-by-step explanation:
f(2) = 6 (what multiplies 2 to equal 6?)*2 = 6
It seems like x gets multiplied by three. Let's check the next one:
f(-1) = -3
Ah ha! We were right. Let's check one more time:
2 * 3 = 6
-1 * 3 = -3
f(x) just means what is f when x is any number. This function that we covered above is: f(x) = 3x
Answer:
21
Step-by-step explanation:
7 * 3 =21
Answer:
yo that's too hard it should be 20 points
Answer:That is not the solution explanation: because if you put the 0 in place of the x in the equation, y would have to equal 6. If you put the -2 in place of the y then x would have to equal 8.
Simpler explanation: 0 + -2 = -2 not 6
