Answer:
x-1+\frac{4x-3}{x^2+2x+1}
Step-by-step explanation:
Answer:
Well, in order o figure this out, you have to understand the definition or range.
Range is the difference between the lowest and highest values.
Since 78 use to be the highest number, the range was 55
Now when we remove the outlier, the new highest value is 45, decreasing the range to 22.
Hope this helps!
The factored form is 25y^2 + 8 if the 2 was supposed to be an exponent.
X + y = 62
x - y = 12
Move x over so y is alone in one of the above equations,
y = 62-x
Now substitte in y
x-(62-x) = 12
x - 62 + x = 12
2x = 12 + 62
2x/2 = 74/2
x = 37
Now for y sub in the x!
x + y = 62
(37) + y = 62
y = 62 - 37
y = 25.
So 25 + 37 =62
and 37 - 25 = 12
Method 2 :
Start by stacking the 2 original equations from above,
x+y=62
x-y=12
You want to "cancel" out one of the variable so,
x+y=62
+ + = +
x - y =12
So then you add,
2x = 74
2x / 2 = 74 / 2
x = 37.
Now you can once again sub it back into the original equation to solve for y,
x+y=62
(37)+y=62
y=62-37
y=25
Hope this helps!
Answer:
The number is -6
The second operation is -60
Step-by-step explanation:
Let the number be x.
Solving (a): The value of x
Operations 1:
Multiply by 3: 3x
Add 40: 3x + 40
Operations 2:
Add 17: x + 17
Multiply by 2: (x + 17) * 2
To find x, equate both operations.
Collect like terms
Solving (b):
Operations:
Subtract 9: 
Multiply by 4: 
This gives:
