The solutions for ‘x’ are 2 and -5
<u>Step-by-step explanation:</u>
Given equation:
Since the base on both sides as ‘12’ are the same, we can write it as
Often, the value of x is easiest to solve by by factoring a square factor, setting each factor to zero, and then isolating each factor. Whereas sometimes the equation is too awkward or doesn't matter at all, or you just don't feel like factoring.
<u>The Quadratic Formula:</u> For , the values of x which are the solutions of the equation are given by:
Where, a = 1, b = 3 and c = -10
So, the solutions for ‘x’ are
The solutions for ‘x’ are 2 and -5
Answer: Option 4: -2sin(x + pi/2) - 1
Step-by-step explanation:
When this equation is graphed, the y-intercept is -3 which is what the image shows. None of the others have a y-intercept at -3.
Hope this helps!
I like to divide by 2 first, and 347 divided by 2 is 173.5, so obviously this won't turn out evenly. I then divide 173.5 by 2, and that would be 86.75, so there's your answer!
Hope this helps!
3.
Since you know that you can easily split 4 to get to 2, just split the top as well.
4.
Since you could divide the top by the bottom since numbers already have a denominator of 1.
5.
Then multiply by 10.
Tell me if this helps!!!
A is the only correct answer, unless you meant to put “-5” for letter E. Then A and E would be the correct answers!
