den301095 [7]

Answer:

The number of cats an frogs

Step-by-step explanation:

For some reason the equation has (c+f) grouped off from the rest, since in an equation the first step is to take care of things in the parentheses, first you must add the two together, and based on the description, you know that c is the number of cats and f is the number of frogs.  Therefore adding them together would get the total number of cats and frogs.

If f(x)= 3x+1 is reflect across the y-axis; what would the slope &amp; y-intercept be? *
Elden [556K]

Answer: f(x) = -3x + 1

So the slope is -3 and the y-intercept is 1

Step-by-step explanation:

This is because it’s across the y-axis so the y-intercept doesn’t change. Because it’s a reflection the slope just becomes the opposite of what it originally was, so in this case it will be -3
