Slope is rise over run, i.e., y over x. So, to find slope, take your y values and subtract them. It doesn't matter which one first, just make sure whatever you decide matches with the way you subtract your x values. So, for this, I'll do 3 - -7. Subtracting a negative makes a positive, so you have 10. Do the same to your x values. -1 - 4 is -5. Now, you have the fraction 10/-5, which simplifies to -2. Your slope, therefore, is -2. Hope this helps!

Defin was given a riddle to solve: the sum of two consecutive positive integers is 71. find the to positive integers.
seropon [69]

Answer:

The two numbers are 35 and 36.

Step-by-step explanation:

While you could do this question just by 'guess and check', the best way to do it is to divide 71 by 2, which gives 35.5. So out two numbers should be approximately equal to 35.5. So we just take the two closest: 35, and 36, which are consecutive (consecutive means 'one after the other'), and we see add to 71.

So we see that 35 and 36 is the answer.

What is the value of f(-2)?
kvasek [131]

Hi, here is the solution...

We need to find the value of f(-2).

The value of x = -2 comes under the second function f(x) = 4x, where -3≤x≤-1.

To find the value of f(-2), plug in x = -2 in f(x) = 4x

f(-2) = 4 (-2)

f(-2) = -8.

The answer is -8.


Thank you :)
