Answer:
(1, 6)
Step-by-step explanation:
Use elimination or substitution (elimination is easier)
Answer:
The thing you should notice is that when we multiply a number by 10^n
(where n is the number of zeros that the number has) we move the decimal point on the first number n times to the right.
For example, if we have the number:
7.231 and we multiply it by 100 (there are 2 zeros) then the decimal point is moved two times to the right:
7.231*100 = 723.1
This happens because the base of our math is 10 (the decimal system).
Answer:
y = 25x + 100
Step-by-step explanation:
The cost (y) is the sum of the sign-up fee (100), and the monthly cost (25) multiplied by the number of months (x).
y = 100 +25x
K bro i gotchu it's 75 my dude.
Hope this helps have any questions I can help ya with it
2x^2 + 10x = 0
we can take out x from both terms and we get:
x(2x + 10) = 0
now either x has to be equal to 0 or 2x + 10 has to be equal to zero in order for equation to be equal to 0.
one solution is x=0 as stated above
other is:
2x + 10 = 0
2x = -10
x = -10/2 = -5
Answers are x=0 and x = -5.
