Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, select the statement that could be true for g. A. g(-4) = -11 B. g(7) = -1 C. g(-13) = 20 D. g(0) = 2
Answer:
C
Step-by-step explanation:
C can be true, because -13 is inside the defined domain, and 20 is inside the defined range.
A cannot be true, because -11 is outside of the defined range.
B cannot be true, because 7 is outside of the defined domain.
D cannot be true, because g(0) has already a different assigned result value : -2. and in a function no x can have multiple assigned result values.

Answer:
[tex]1\frac{1}{3}[/tex]
Step-by-step explanation:
Given the following question:
[tex]5\frac{1}{3} \div4[/tex]
To find the answer convert the mixed numbers into improper fractions and then divide using KCF. (Keep, Change Flip)
[tex]5\frac{1}{3} \div4[/tex]
[tex]5\frac{1}{3} =3\times5=15+1=16=\frac{16}{3}[/tex]
[tex]\frac{16}{3} \div4[/tex]
[tex]4=\frac{4}{1}[/tex]
[tex]\frac{16}{3} \div\frac{4}{1}[/tex]
Apply KCF:
[tex]\frac{16}{3} \div\frac{4}{1}[/tex]
[tex]\frac{16}{3} \times\frac{1}{4}[/tex]
[tex]16\times1=16[/tex]
[tex]3\times4=12[/tex]
[tex]=\frac{16}{12}[/tex]
Simplify by reducing:
[tex]\frac{16}{12}[/tex]
[tex]16\div4=4[/tex]
[tex]12\div4=3[/tex]
[tex]=\frac{4}{3}[/tex]
Convert into mixed number:
[tex]\frac{4}{3}[/tex]
[tex]\frac{4}{3} =4\div3=1\frac{1}{3}[/tex]
[tex]=1\frac{1}{3}[/tex]
Which means your answer is "4/3 or 1 1/3."

Answer:
50 the answer is 50
Step-by-step explanation:
50% that's it ok?
Hi, I believe your answer is ---150%--- because if each square is one whole, that makes them 200% combined. Since one square is only halfway shaded, it is only 50%. I hope this helps you! Good luck and have a great day. :)

Consider the expression below. 1.3 + 1.25
Sarah thinks that this sum will be an irrational number. Is Sarah's classification correct? Why or why not?
A Sarah is not correct, because 1.3 + 1.25 can be rewritten as + which results in the rational sum of 2
B. Sarah is not correct, because 1.3 + 1.25 results in a decimal number and all decimals are rational.
C. Sarah is correct, because 1.25 cannot be rewritten as a fraction which means the sum is irrational.
D.
Sarah is correct, because 1.3 cannot be rewritten as a fraction or terminating decimal which means the sum is
irrational
Answer:
First, let's find out the sum;
1.30 + 1.25 = 2.55, is rational, so A
Step-by-step explanation:
The reason being this is because, 2.55 is a terminating decimal meaning that the decimal place does not go on forever.
Sara's classification is not correct because the sum is a rational number.
What is an irrational number?Irrational numbers are real numbers that cannot be expressed in fractions.
First, we can find the sum
i.e 1.3+1.25 = 2.55
Here, 2.55 is a rational number.
51/20 = 2.55
Since the sum is a rational number Sarah is not correct.

Answer:
m<ACD = 124 degrees
Step-by-step explanation:
(2x+8) + (x-2) = 180 degrees
This is because both angles are on the same line (so they are a linear pair) and a straight line is 180 degrees. This means that they are supplementary
So:
(2x+8) + (x-2) = 180
Combine like terms:
2x + x + 8 - 2 = 180
3x + 6 = 180
-6 -6
3x = 174
Divide both sides by 3
x = 58
Now that you know x, you can put it into the equation for m<ACD:
2x+8
(2 multiplied by 58) + 8
(116) + 8
124
m<ACD = 124 degrees
