2 hours and 45 minutes
Step-by-step explanation:
you add the 15 and 30 and then add 2 hours.
Answer: positive
Step-by-step explanation:
A negative divided by another negative is always positive. Same rule applies to multiplication. Double negatives equal positives
Answer:
(2x^2 + x-3)/(4x^2-9)
Step-by-step explanation:
The denominator looks like an expression in which we have applied the difference of two squares to
In that case, we know that;
a^2-b^2 = (a-b)(a+ b)
That means we would be have 2x + 3 as the other denominator factor and the expression at the denominator would be;
(2x + 3)(2x-3) = 4x^2 - 9
Also, we would have to cancel out 2x + 3 from the numerator too, so as to be left with only the binomial
That means;
(2x+3)(x-1) = 2x^2-2x+ 3x - 3 = 2x^2+x -3
So we have the original expression as;
(2x^2 + x-3)/(4x^2-9)
Alternate means it will be across and on the opposite side, there for the alternate interior angle for 2 would be the same number as the function you're solving.
For example: if you're going to find the alternate interior of 17x+9, it will be 17x+9, the angle on the lower right hand side of the top parallel line.
Graph A shows a single solution where the two lines cross paths. Graph B shows a case where there are no solutions as the lines will never touch. Graph C is the correct answer as it shows the two lines constantly intercepting each other, creating an infinite number of solutions.
