Answer:
f(-2) = -7
Step-by-step explanation:
To find the answer, you simply need to substitute -2 into f(x). Like this,
f(-2) = 2(-2) - 3
Then, you must simply solve the rest of the equation.
f(-2) = -4 - 3
f(-2) = -7
That is how you find the answer.
Answer:
A)
Step-by-step explanation:
The answer is: y = 2/3x - 14
Answer:X= -4
Step-by-step explanation:
6 less than the product of a number and 3 is -18.
Make each part of the sentence into numbers:
"<u>the product of a number and 3</u>": becomes X*(3), where X is the "number."
"6 less than": is -6, so we have:
X*(3) - 6
<u>"is -18" </u> means = -18
Put the segments into one equation and solve:
X*(3) - 6 = -18
3X-6=-18
3X = -12
X = -4
====
See if this works: If X=-4, then the product of it and 3 is -12. Six less than -12 is -18. And that is correct. X= -4
