Just look for the bottom point and then you'll find your answer
-4y and +2x
Answer: 78.5
Step-by-step explanation: Assuming you use 3.14 for pi, then 5^2 times 3.14 equals to 78.5. If you use the real number for pi, then it is going to be 78.54/
Answer:
0.06 x 60 = 3.6
When you find the percent of a number, just turn the percent to a decimal and multiply it by that number.
Answer:
The point for the given linear equations is ( , )
Step-by-step explanation:
Given as :
The two linear equations are
First equation
y = x + 5
Or, y + x + 5 = 0
Taking LCM we get
y + x + 10 = 0 .......1
Second equation
y = 2 x + 2 ........2
Now solving both equation
Putting the value of y from eq 2 into eq 1
(2 x + 2) + x + 10 = 0
Or, 3 x + 12 = 10
Or, 3 x = 10 - 12
Or, 3 x = - 2
∴ x =
Now putting the value of x into eq 2
∵ y = 2 x + 2
Or, y = 2 × + 2
Or, y = + 2
Or, y =
∴ y =
So, The points are (x , y ) = ( , )
Now, plotting the points on x-y coordinate graph
Hence, The point for the given linear equations is ( , ) Answer
Answer:
The other rational number in the operation given is:
Step-by-step explanation:
To obtain the number in the operation given, we're gonna represent the operation:
Where:
- r = the other rational number.
Now we are going to solve r to identify its value in numbers:
- (We pass a number that is multiplying to the left of the equal, to divide to the right of the equal symbol)
As you can see, when we operate, <u>the result is 6/5</u>, and we can prove this multiplying as we had in the original equation, replacing r by 6/5:
- r * 15/14 = 9/7
- 6/5 * 15/14 = 9/7
- 9/7 = 9/7
In this form, we know the result is correct.
