answer is (-7,2)
y = -x -5
y= x+9
Both equations have y on the left hand side
So we equate both equations
We replace -x-5 for y in the second equation
-x -5 = x+9
Subtract x on both sides
-2x -5 = 9
Now add 5 on both sides
-2x = 14
Divide by -2 from both sides
x = -7
Now plug in -7 for x in the first equation
y = -x -5
y = -(-7) -5= 7-5 = 2
So answer is (-7,2)
= 1

Answer:
8111.5
Step-by-step explanation:
Deduct for thousand eleven hundred and a half from twelve thousand twelve hundred and twelve
Rewriting the above question in figure :
4000 + 100 + 0.5 = 5100.5
12000 + 1200 + 12 = 13212
13212 - 5100.5 = 8111.5
= 8111.5
Answer:
Step-by-step explanation:
Given:
The expression to simplify is given as:
In order to simplify this, we have to use the law of indices.
1.
So,
Substitute this value in the above expression. This gives,
Now, we use another law of indices.
2.
So,
Substitute these values in the above expression. This gives,
Finally, we further simplify it using the law
So,
Therefore, the given expression is simplified as:
