PLEASE HELP ME EXPLAIN THE ANSWER

Mathematics
1 answer:
tigry1 [53]3 years ago
8 0

Answer:

  See the attachment

Step-by-step explanation:

The inequalities resolve to ...

  x ≥ 1 or x ≤ -3

You have chosen the correct placement of the lines on the number line. The "or equal to" symbol (≥ or ≤) means the dots at -3 and +1 are filled in, indicating those numbers are part of the solution.

If the ">" or "<" symbol is used in the inequality, the dot is left open, as in the answer you selected. The open dot indicates that value is not part of the solution set.

What is f(g(x)) when f(x) = x2 + 5, and g(x) = 10 - 5x?
Mashutka [201]

Answer:

D

Step-by-step explanation:

To obtain f(g(x)) substitute x = g(x) into f(x), that is

f(10 - 5x)

= (10 - 5x)² + 5 ← expand (10 - 5x)²

= 100 - 50x - 50x + 25x² + 5 ← collect like terms

= 25x² - 100x + 105 → D

Identify the ordered pair on the graph of the equation 2x + 5y = 4.
Colt1911 [192]
What you would do is you would substitute each ordered pair into their respective variables. (ie. for (0,1) you would put 0 where the x is and 1 where the y is) You would then solve the equation. If the equation is not even (ie. 2=5 would not be even but 4=4 would be), you move on to the next ordered pair.

If you follow the process right and you get the equations correct, the answer should be B. (7,-2)
