The Answer is -3/2
Below is how I got that answer
(-12) / 6+2
-12/ 8 (Simplify the problem by adding 6 and 2, remove the parenthesis).
-3/2 (Simplify -12/8 by dividing it by 4)
Answer:
7- (y/4)
Step-by-step explanation:
g(x) = x^3 − x^2 − 4x + 4
g(x) = x^3 + 2x^2 − 25x − 50
g(x) = 2x^3 + 14x^2 − 2x − 14
<u>Corrected Question</u>
Is the function given by:
continuous at x=4? Why or why not? Choose the correct answer below.
Answer:
(D) Yes, f(x) is continuous at x = 4 because
Step-by-step explanation:
Given the function:
A function to be continuous at some value c in its domain if the following condition holds:
- f(c) exists and is defined.
- exists.
At x=4
Therefore:
By the above, the function satisfies the condition for continuity.
The correct option is D.
Answer:
21 and 22
Step-by-step explanation:
Let's work backward from that 81%: x/25 = 0.81 yields x = 20.25. Nominally, 20.25 / 25 = 0.81, but x must be an integer. Let's round 20.25 off to 20.
Thus, if Kalsom got 81%, it was a result of his having done 20 questions correctly.
81% corresponds to 20 questions correct;
82% to 20.5 questions correct, or, rounding up, to 21 questions correct;
83% to 20.75, or 21;
84% to 21 questions correct; this is the only result that makes sense (whole number of questions answered correctly)
85% to 21.25;
86% to 21.5;
87% to 21.75;
88% to 22 questions correct (this makes sense, unlike the last three)
89% to 22.25;
90% to 22.5;
91% to 22.75;
Assuming that the number of questions correct MUST be integer, then the possible number correct are 21 and 22, corresponding to 84% and 88% respectively.
