Answer:
Step-by-step explanation:
Because if you add 18x to both sides of the equation, you get 0 = -18
Step-by-step explanation:
When you combine like terms in the equation, you get -18x = -18x - 18. After adding 18x to both sides, you have 0 = -18. This is not true, which means that there are no solutions to the equation.
Answer:
(0,150)
Step-by-step explanation:
Remember that the y-intercept of a function is where x=0. Therefore, we need to plug in x=0 in the function to get y:
f(x)=150(1.25)^x
f(0)=150(1.25)^0
f(0)=150(1)
f(0)=150
Therefore, the y-intercept of the function is (0,150)
Answer:
Step-by-step explanation:
Tiger Algebra gives you not only the answers, but also the complete step by step method for solving your equations 4x^2-2=38 so that you ... Step 2 : Step 3 :Pulling out like terms. 3.1 Pull out like factors : 4x2 - 40 = 4 • (x2 - 10) ... x2 = 10. When two things are equal, their square roots are equal.
50% of 18 = 9
so buy 1 for 18 and 1 for 9 = 18+9 = 27 for 2 sheets
6/2=3
27 x 3 = 81 for 6 sheets
Answer:
original number = 53
Step-by-step explanation:
In two digits number:
Let the tens place digit be x and units place digit be y.
So,
Original number = 10x + y
Number obtained after reversing the digits = 10y + x
According to the first condition:
x + y = 8.... (1)
According to the second condition:
10y + x = 10x + y - 18
10y + x - 10x - y = - 18
9y - 9x = - 18
-9(x - y) = - 18
x - y = - 18/(-9)
x - y = 2.......(2)
Adding equations (1) & (2), we find
x + y + x - y = 8 + 2
2x = 10
x = 10/2
x = 5
Plug x = 5 in equation (1), we find:
5 + y = 8
y = 8 - 5
y = 3
10x + y = 10*5 +3 = 50 + 3 = 53
Hence, original number = 53
