The Exponent tells you how to move the decimal to the right. So
-2.56 x 10^3 says move the decimal 3 places to the right:
-2560 is the original number ~ Which Im guessing is the standard form...
Answer:
x=7+1/2
Step-by-step explanation:
We move all terms to the left:
3(x+4.5)-(36.)=0
We add all the numbers together, and all the variables
3(x+4.5)-36=0
We multiply parentheses
3x+13.5-36=0
We add all the numbers together, and all the variables
3x-22.5=0
We move all terms containing x to the left, all other terms to the right
3x=22.5
x=22.5/3
x=7+1/2
Step-by-step explanation:
x = 5
x = -7
x = 18
x = 14
these are the answers, comment if you still have doubts.
Answer:
4
Step-by-step explanation:
The x-intercept occurs when y=0, if you think about it graphically. Plug y=o into your equation:
10x - 5(0) = 40
10x = 40 (divide each side by 10)
x=4
