If you mean the gradient then it would be -3/2 because if you multiply the 2 together they equal minus 1. That’s how u figure out if 2 lines are perpendicular
The answer is 0.875 just switch it to a fraction I can’t help you with everything!
Answer: see below
Step-by-step explanation:
|2x+5|=7
2x+5=±7 ⇔ since the absolutely value of any number is all positive, so the value in side can be either positive or negative
2x+5=7 or 2x+5=-7
2x=2 2x=-12
x=1 or x=-6
----------------------------------------
The product of the two solutions
1 × -6=-6
Hope this helps!! :)
Please let me know if you have any question
Domain of 3ˣ = ( -∞, ∞ )
<em>Note : Domain of an exponential function is always ( -∞, ∞ )</em>
Your answer is <em>infinitely</em><em> </em><em>many</em><em> </em><em>solutions</em><em> </em>
Step-by-step explanation:
-4x+-20=-4x-20
+4× +4x
(4x cancel out)
Your left with
-20=-20
Therefore your answer is infinitely many solutions
