Answer:
The answer is b
Step-by-step explanation:
the slope is going upwards to towards quadrant 1 so the slope is positive. slope is also defined by rise/run, y/x. you can see that it goes upwards by one and right 2 times to get to the next value point; that means it is 1/2.
Looks like the integrand is
The denominator is factorized as
Then we want to find constants such that
We can use the cover-up method to easily find and :
Answer:
24
Step-by-step explanation:
just multiply 2 on both sides
Answer: Choice D) 7x+2; all real numbers
-----------------------------------------------------
Work Shown:
f(x) + g(x) = [ f(x) ] + [ g(x) ]
f(x) + g(x) = [ 4x-5 ] + [ 3x+7 ]
f(x) + g(x) = 4x-5 + 3x+7
f(x) + g(x) = (4x+3x) + (-5+7)
f(x) + g(x) = 7x+2
The domain of y = 7x+2 is the set of all real numbers. There are no restrictions to worry about such as dividing by zero or taking the square root of a negative number. We can plug in any real number we want for x to get some output for y. This is one of the many properties of linear equations.
