I need help solving this problem
Ludmilka [50]
G(f(2)) means work out whatever f(2) is then plug this into g(x).

So f(2) is 3 because we just find the x-value 2 in the left hand column and read across. This is 3.

So then we find g(3) by finding the x-value 3 in the left hand column and read across. This is 10.

So g(f(2)) = 10

The equation below represents Function A and the graph represents Function B:
kozerog [31]

The slope of function A is the coefficient of x, which is 6.

The slope of function B is the rise divided by the run, which is 3/1 = 3.

The appropriate choice is ...

... c) Slope of Function A = 2×Slope of Function B

The sum of the first and third of three consecutive even integers is 136. find the three even integers.
tatyana61 [14]
Based on your problem, you only have one given. So, you can't make an equation for this because there are not limits to the equation. The only thing that you know is that the three numbers are consecutive even integers. My way of solution for this is trial-and-error. However, it's really quite easy. 

For example: 42 + 46 = 88. I have to increase the numbers more to reach 136. Suppose: 82 + 86 = 168. That exceeded 136. So, it must be between 46 and 82. Suppose again: 66 + 70 = 136. Therefore, the sequence of the consecutive even integers are 66, 68, and 70.
