Let f(x) = 12 over the quantity of 4 x + 2. Find f(−1). (1 point)
mylen [45]

Answer:

-6

Step-by-step explanation:

Hope I understand your "f(x) = 12 over the quantity of 4 x + 2" correctly

f(x) = 12 / 4x +2

Now so they want a f(-1), as u can see they substituted the x for - 1, therefor do that the same to the right side

f(-1) = 12/ 4(-1) + 2

f(-1) = 12 / - 4+2

= 12/ - 2

= - 6

What grade is 92% out of 115
KatRina [158]
To calculate this, we need to do the following:

92 * 115 = 10580 (we first multiply the percentage with our number)
 
10580 / 100 = 105.8 (and divide what we get by 100 to get the final answer)

And this is also already the answer: 105.8
