Answer:
in the chapter 7 in class 9 Ex 7.3
one time - and second time +
Step-by-step explanation:
x-2=4+x
1) x-2=-(4+x)
x-2=-4-x
x+x=-4+2
2x=-2
x=-2/2
x=-1
2) x-2=4+x
=0
Answer: 
Step-by-step explanation:
By definition, the "Difference" is the result of a subtraction.
It is important to remember that Scientific Notation is in the following form:

Where "a" is a number between 1 and 10 ( but not including 10) and "b" is an Integer.
In this case, according to the information given in the exercise, you know that the Petronas towers are 1,483 feet tall and the Key tower is 947 feet tall.
Then, the diffrence between the heights of those towers can be find by subtracting them. So, this is:

In order to write the difference calculated above in Scientific notation, the Decimal point must be after the first digit; then you must move the Decimal point two places to the left. Therefore, you get that this is:

Answer:
58.3333333333
Step-by-step explanation:
Answer:
First, we need to find the slope of this line.
Slope is defined as rise over run, or change in y over change in x. We find two points on this line, and see that the slope is -4.
Then, we find the y-intercept, which in this case is 0.
Using slope intercept form, our answer is y=-4x
