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.

Answer:
1 miles.
Step-by-step explanation:
2/4 + 5/6 = ?
We must convert these fractions to the same denominator so we can add fractions. Least common multiple of 4 and 6 is 12.
2/4 = 6/12
5/6 = 10/12
6/12 + 10/12 = 16/12
16/12 = 4/3
4/3 = 1
Answer: 1/56
Step-by-step explanation:
Since the box has 8 different colors, the probability of picking any color of crayon will be 1/8.
This question relates to a probability without replacement, therefore, the probability of picking the red crayon first will be 1/8. After then, there'll be 7 crayons left and the probability of picking the green crayon next will be 1/7.
Therefore, the probability that I will remove the Red and the Green crayon from the box will be:
= 1/8 × 1/7
= 1/56
Answer is A. Hope this helped
