Show work for Max’s part and explain why he got it wrong and how you know this? Need help be detailed please!
Answers
Ann factored the expression completely
Max did not factor completely
Explanation:
The trinomial: 4x^2 - 6x - 4
ax^2 + bx + c
Factors of 16 = 2 and 8
The sum of -8 and 2 gives -6, while the product gives -16 (a × c = 4× 4)
we factorise:
4x^2 -8x + 2x - 4
4x (x - 2) + 2(x -2)
(4x + 2) (x - 2)
factorising completely, 2 is common to the first expression in bracket
2(2x + 1)(x - 2) = 2(x - 2)(2x + 1)
Ann factored: 2(x - 2)(2x + 1)
Max factored: (x - 2)(4x + 2)
From our workings, we can see Ann factored the expression completely
Max did not factor completely
Reason: one of the factors of the expression could still be factorise
4x + 2 can be factorise as 2(2x + 1)

your cell phone bill is $24.99 per month plus $0.16 for each text you send or receive. you have at most $29 to spend on your cell phone bill. What is the maximum number of texts you can send or receive next month?
Answers
The maximum number of texts to send or received in next month will be
25.
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Cell phone bill = $24.99 per month
Cost of each text to send or receive = $0.16
Now,
You have at most $29 to spend on your cell phone bill.
Let number of text to send or receive = x
So, We can formulate;
$24.99 + $0.16x < $29
Solve for x as;
$24.99 + $0.16x < $29
Subtract 24.99 we get;
$0.16x < $29 - $24.99
$0.16x < $4.01
Divide by 0.16 we get;
x < 25.06
After rounding we get;
x < 25
Thus, The maximum number of texts to send or received in next month will be 25.

4. Johnny's Cab charges a fixed cost of $3.75 plus $1.25 per kilometer.a.Write an equation that relates the fare to the distance travelled.b.What is the total cost for a 21-km ride?
Answers
a.
- The independent value is $3.75.
- The dependent value is $1.25 because it depends on the kilometer ride.
- Let us set x for each kilometer.
- Let us set F for the toral fare
Then, we can write the next equation that relates the fare to the distance.
[tex]F=3.75+1.25x[/tex]b.
If we want to find the total cost for a 21-km ride. Then, we need to set x=21 on the equation.
Hence,
[tex]\begin{gathered} F=3.75+1.25(21) \\ F=30 \end{gathered}[/tex]Hence, a 21-km ride has a total cost of $30.

A local theater sold 135 tickets to a matinee play with a total revenue of $2,367.00where they charged $25.00 for an adult ticket and $13.00 for a child's ticket. Usingthe variables a and c to represent the number of adult tickets sold and the number ofchildren's tickets sold respectively, determine a system of equations that describes thesituation.Enter the equations below separated by a comma.How many adult tickets were sold?How many children's tickets were sold?Pls see the picture
Answers
Given:
• Total number of tickets sold = 135
,• Total revenue = $2,367.00
,• Cost of each adult ticket = $25.00
• Cost of each child ticket = $13.00
Let's write a system of equations that describes this situation.
Let a represent number of adults tickets sold.
Let c represent number of children tickets sold.
We have the system of equations:
• a + c = 135
,• 25a + 13c = 2367
Let's solve the system using substitution method.
• Rewrite the first equation for a.
Subtract c from both sides:
a + c - c = 135 - c
a = 135 - c
• Substitute (135 - c) for a in equation 2:
25(135 - c) +13c = 2367
Apply distributive property:
25(135) + 25(-c) + 13c = 2367
3375 - 25c + 13c = 2367
3375 - 12c = 2367
• Subtract 375 from both sides:
3375 - 3375 - 12c = 2367 - 3375
-12c = -1008
Divide both sides by -12:
[tex]\begin{gathered} \frac{-12c}{-12}=\frac{-1008}{-12} \\ \\ c=84 \end{gathered}[/tex]Substitute 84 for c in any of the equations:
a = 135 - c
a = 135 - 84
a = 51
We have:
a = 51, c = 84
Therefore, 51 adult tickets and 84 children tickets were sold.
ANSWER:
• System of equations:
a + c = 135, 25a + 13c = 2367
• Number of adult tickets sold = 51
,• Number of children tickets sold = 84

We will investigate how to evaluate a given function as per the indicated value of the independent variable.
A function is defined as a relationship between two variables ( x and y ). One of these variables mostly ( x ) is denoted as an independent quantity and ( y ) as the independent quantity.
A unique mathematical relationship is expressed between the two variables. Where, the independent variable ( x ) serves as an input to the function. The function is then evaluated on the basis of mathematical manipulation to give the output ( y ).
We have a function g ( x ) defined as follows:
[tex]g\text{ ( x ) = 3x + 12}[/tex]We are to evaluate the above function for the indicated value of the input ( independent variable ) - x as follows:

For this problem, we were informed that 1/15 of the fence was painted in 15 minutes. We need to calculate the time it will take to paint the whole fence, assuming that the same speed is maintained.
In order to do that we need to assign a variable "t" to the time it will take to paint the fence, then we need to multiply the fraction 1/15 with this variable, and make it equal to 15 minutes, then we need to solve for "t". This is done below:

If a company has a dividend yield of 2.5%, a share price of $18 per share, how much will I receive in dividends if I own 10,000 shares? Do not include commas or the dollar sign in your answer.
Answers
In order to determine how much you will reiceive in dividens, you first calculate the price of your shares, which are 10,000 shares.
18(10,000) = 180,000
The cont of your shares are $180,000.
Next, you calculate the 2.5% of the previous cost, just as follow:
(2.5/100)(180000) = 4500
Hence, you will receive 4500 dollars due to the dividens of the price of your shares.
How many solutions does the equation 6z + 1=2(3z -1) have?
Answers
Answer:
No solutions
Step-by-step explanation:
6z + 1 = 2(3z - 1)
6z + 1 = 6z - 2 (using pemdas you use the distributive property)
Next you want to combine like terms.
To get both z's on the same side you have to subtract it from one side. However, what you do to one side you must do to the other. Once you subtract 6z from both sides you are left with only numbers. Since you do not have a variable to solve for now this equation has no solutions.
Hope this helps!
The equation 6z + 1 = 2(3z - 1) has no solutions.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
6z + 1 = 2(3z - 1)
Solve for z.
6z + 1 = 2 (3z - 1)
6z + 1 = 6z - 2
1 = -2
This means,
No solutions.

[tex]\begin{gathered} x^2=60^2+63^2 \\ x^2=3600+3969 \\ x^2=7569 \\ x=\sqrt[]{7569} \\ x=87\text{feet} \\ \therefore x=87feet \end{gathered}[/tex]Hence, the cost of garland Mia will need to reach from one corner of the ceiling to the opposite corner is 87feet.

the United States Air Force has 19 women for every 81 men enlisted in a squadron has 750 member approximately how many women round your answer to the nearest whole number
we have that
Let
x -----> the number of women
y ----> the number of men
so
x+y=750 -------> equation A
x/y=19/81--------> y/x=81/19
y=(81/19)x ------> equation B
substitute equation B in equation A
x+(81/19)x=750
solve for x
(100/19)x=750
x=(750*19)/100
x=142.5
therefore
the number of women is 143Drag each example to the correct mathematical property listed.DRAG & DROP THE ANSWERAdditive IdentityAdditive Inversea.l=a12. = 1a + 0 = aa +(-a) = 0Multiplicative IdentityMultiplicative Inverse

If a voter who plans to vote “yes” on issuePis randomly selected, what is the probability thatvoter also plans to vote "no" on issue Q?
Answers
Consider that the probability of an event is given by,
[tex]\text{Probability of an event}=\frac{\text{ No. of events favorable to the event}}{\text{ Total possible no. of outcomes}}[/tex]Consider the following events,
A = event that a voter plans to vote 'yes' on issue P
B = event that a voter plans to vote 'no' on issue Q
Then, given that event A has already occurred, the probability of occurrence of B, is given by,
[tex]P(\frac{B}{A})=\frac{P(A\cap B)}{P(A)}[/tex]Determine which if any of the triangles are similar. If they are then give the scale Factor
Answers
EXPLANATION
The triangles that are similar are the first and the third one. {△ABC and △RST}
The scale factor can be obtained by dividind two corresponding sides, as for instance, the hypotenuses, 12/6= 2
The scale factor is 2
