Answer:
The answer is 1 or infinite solutions
Step-by-step explanation:
When you plug in the value of -5.5 into the equation, you will eventually end up with -17.5=-17.5, making the answer infinite or 1.
Answer:
-1/3
Step-by-step explanation:
Answer:
The value of y for x = 8 is 60 .
Step-by-step explanation:
Given expression as :
For x = 2 , y = 15
Let the equation be written with constant k'
So, y = k x
Or, k = 
∴ k = 
<u>Now, again </u>
For x = 8
equation can be written as
y = k x
Or, y =
× 8
Or, y = 
∴ y = 15 × 4
I.e y = 60
Hence The value of y for x = 8 is 60 . Answer
Not quite sure what you mean by brackets, but you can get the solution to this equation in a few steps:
<span>(-2x - 1)</span>² <span>= 0 ... square root both sides to eliminate the squared binomial
</span>√(-2x - 1)² = √0 ... simplify; the square is canceled out and the root of 0 brings you back to 0
-2x - 1 = 0 ... solve like a two-step equation
-2x = 1
x = -1/2 is your x-value.
