Hi! I’m super confused on the second page but for the first page I only need help on #11. Could you please let me know if the problems I did answer on the first page are correct?

Answer:
So ummmm..... I personally think that all of your answers on the first page should be flipped.
Second page:

#10: Domain= (-infinity, infinity) range: (-infinity, infinity)
#11: Domain= (-infinity, infinity) range: [-2, infinity)

The domain and range of a
The domain of a function is set values of the input to the function where the function is defined
The range of a function are is the set of the output values of the function
9. The given figure of a square is not a function
10. The graph extends to infinity towards the top right, and the bottom left
The domain of the function is; -∞ < x < ∞The range of the function is; -∞ < x < ∞11. The graph of the function extends infinity at the top left and top right
Therefore, the domain of the graph is; -∞ < x < ∞The graph has a minimum at y = 2, while it extends to infinity as the y-values increases, therefore;
The range is; 2 ≤ y < ∞12. The graph of a circle is not a function

What is the correct answer for Dean's problem? Explain where he went wrong.
Answers
Answer:
The slope is 5/-2.
Step-by-step explanation:
Slope is y1-y2 over m1-m2 (rise over run). The first ordered pair is -2 (m1) and 11 (y1). We then subtract the second ordered pair (4 (m2) and -4 (y2)) from the first.
11 - (-4) = 11 + 4 = 15
-2 - 4 = -6
Remember, slope is rise over run (y over x), so the slope is 15/-6. Now, we must simplify. 15/-6 = 5/-2
Dean went wrong because he thought that slope was run over rise (x over y). If he had switched the two numbers, his answer would have been correct.

Answer:
The answer is x = 7
Step-by-step explanation:
Divide each term by 3 and simplify. Move all terms not containing x to the right side of the equation.
Answer:
[tex]\huge\boxed{x=7}[/tex]
Step-by-step explanation:
In order to solve for x, our goal is to isolate it on one side of the equation. We can do this by reversing the equation.
Let's apply the distributive property on the left side:
[tex](3 \cdot x) + (3 \cdot -10) = -9\\\\3x-30=-9[/tex]
Add 30 to both sides:
[tex]3x - 30 + 30 = -9 + 30\\\\3x = 21[/tex]
Divide both sides by 3:
[tex]3x \div 3 = 21 \div 3\\\\x = 7[/tex]
So x = 7.

hi! to find the sum of the soup mix, we have to add all the fractions together.
7/4 + 1/2 + 5/3 + 1/3 +1/4 + 1/2
we have to find a common denominator for each, which is the LCM of the denominators. this would be 12. let's change the fractions so we can add them up.
21/12 + 6/12 + 20/12 + 4/12 + 3/12 + 6/12
add the numerators and keep the denominators the same.
(21+6+20+4+3+6)/12
60/12
this simplifies to 5.
the total amount of soup mix is 5 cups.
Answer:
5 cups of soup mix
Step-by-step explanation:
Make all the denominators equal. The lowest common denominator is 12 so multiple the denominators with 4 by 3, 2 by 6, and 3 by 4.
[tex]\frac{7}{4} *3=\frac{21}{12}[/tex]
[tex]\frac{1}{2} *6=\frac{6}{12}[/tex]
[tex]\frac{5}{3} *4=\frac{20}{12}[/tex]
[tex]\frac{1}{3} *4=\frac{4}{12}[/tex]
[tex]\frac{1}{4} *3=\frac{3}{12}[/tex]
[tex]\frac{1}{2} *6=\frac{6}{12}[/tex]
Now that all the fractions have the same denominator you can add them all together.
[tex]\frac{21}{12} +\frac{6}{12} +\frac{20}{12} +\frac{4}{12} +\frac{3}{12} +\frac{6}{12}=\frac{60}{12}[/tex]
Then simplify the fraction to find out how many total cups of soup mix you have.
[tex]\frac{60}{12} =5[/tex]

Answers
Answer: 4/5 book per hour
Step-by-step explanation: in this question, we are to rewrite (2/5)/(1/2) as unit rate.
To write this as a unit rate, what we need to do is to divide 2/5 by 1/2.
That means 2/5 divided by 1/2
Removing the division and replacing with multiplication will give 2/5 * 2/1 = 4/5 books/hour

What is a polynomial expression?Polynomial is made up of two terms, namely Poly (meaning “many”) and Nominal (meaning “terms.”). A polynomial is an expression composed of variables, constants, and exponents, combined using mathematical operations such as addition, subtraction, multiplication, and division (No division operation by a variable). Based on the number of terms present in the expression, it is classified as monomial, binomial, and trinomial. For example P(x) = x2-5x+11
Given here; a polynomial function with leading term 8x⁹
Now The Degree of a Polynomial is the largest of the degrees of the individual terms. The degree of an individual term of a polynomial is the exponent of its variable and the highest degree of the terms given in the expression is the degree. And thus the expression with leading term 8x⁹ is 9
Hence, The degree of the given polynomial is 9

It will take 5.29 years to double our money if we invest $500 at 14 percent interest.
Step-by-step explanation:
Let we invest $500 with the interest rate of 14% ,
Now we will find the time it is going to take to double the money
here, we use the formula of compound interest [tex]A= P( 1+\frac{r}{n}) ^{nt}[/tex]
Here, A = the amount yielded,
P = principal,
r = interest rate ,
n = number of times per year,
and t = time invested.
Now, put A= 1000 , P= 500 , R= 0.14 T= x and N= 1
[tex]1000=500(1+ 0.14)^x[/tex]
[tex]1000=500(1.14)^x[/tex]
[tex]2=1.14^x[/tex]
[tex]\log_{1.14} (2)=x[/tex]
[tex]x=5.29[/tex]
so , It will take 5.29 years to double our money if we invest $500 at 14 percent interest.
Hence , the answer is 5.29 years .

3 1,050
5 1,750
10 3,500
Answers
Answer:
d = 350tStep-by-step explanation:
From the information given, we need to get the rate of change of distance which is the velocity (slope.)
velocity = Δd/Δt
v = d2-d1/t2-t1
from the table;
when t = 2, d = 700
when t = 3, d = 1050
v = 1050/750/3-2
v = 350/1
v = 350
Since v = d/t
350 = d/t
cross multiply
350t = d
Rearrange:
d = 350t
Hence the equation that represents the information is d = 350t

If cat food is sold in 20 lb bags, what is the least number of bags of cat food needed for one year at this shelter, if 10 lbs of cat food is consumed per week?
Answers
Answer:
26 weeks!
Step-by-step explanation:
Hello there!
There are 52 weeks in a year, believe it or not! So, if 1 bag of food was 10 lbs, then it would be 1 bag of 10lbs x 52 weeks, so it would be 52 bags. However, we are dealing with 20 lb bags, which will last twice as long as the 10 lb bag! So, if 1 bag will last 2 weeks, and there are 52 weeks in a year, then it is weeks divided by number of weeks it takes to consume 1 bag, 52 divided by 2. 52 divided by 2 is 26.
So in 1 year, the shelter will need 26 bags of 20 lb cat food!
Hope I helped!

Answer:
C. The value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days
Step-by-step explanation:
So 5 time 4 equals 20...!
80 minus 20= 60
The value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days, which is the correct answer would be option (C).
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
A student works 80 hours per month and plans to work 5 hours each day, but only on days when work is planned. After working for d days, the function / (d) - 80 — 5d shows the number of hours of work remaining for the month.
⇒ f (d) = 80 - 5d ....(i)
According to option (C),
Substitute the value of d = 4 in equation (i),
⇒ f (4) = 80 - 5(4)
⇒ f (4) = 80 - 20
⇒ f (4) = 60
Thus, the value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days
Hence, the correct answer would be option (C).

Then:
[tex]\frac{11}{2}x + \frac{2}{3}x = 37[/tex]
