32. At 8 AM, the temperature was 3°F below zero. By 1pm, the temperature rose
14F and by 10 PM, dropped 12. Plot points and draw arrows on the number
line below to model this situation.
What was the temperature at 10 PM? Explain how the number line helped you
find your answer.
Answers
Answer: - 1°F
Step-by-step explanation:
Given that:
At 8a.m:
Temperature = 3°F below 0
By 1p.m ; Temperature rose by 14F ;
By 10pm ; temperature dropped by 12F
Temperature at 10 pm:
3°F below 0 = - 3°F
Temperature at 1pm: temperature increased by 14°F
-3°F + 14°F = 11°F
Temperature at 10pm: temperature dropped by 12°F
11°F - 12 = - 1°F

Complete Question
Students in a pre-algebra class are given the polynomial 12x²y - 6xy +18y² and told to factor out the greatest common factor.
Which student has made the correct choice? (1 point)
a) Delia chose 3y because she said that it was a factor of every term.
b) Pedro chose y because he said that the greatest common factor can be found only by looking at the variable terms.
c) Mike chose 6y because he said that it was the largest factor of every term. d) Marisol chose 6 because she said that it was the only greatest common factor in each term.
Answer:
c) Mike chose 6y because he said that it was the largest factor of every term.
Step-by-step explanation:
Step 1
Identify the GCF of the coefficients.
12x²y - 6xy + 18y²
Coefficients are :
12, 6, 18
The Greatest Common Factor for 12, 6, 18 =
The factors of 6 are: 1, 2, 3, 6
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 18 are: 1, 2, 3, 6, 9, 18
Then the greatest common factor is 6.
Step 2
Identify the GCF of the variables.
x²y , xy, y²
The GCF of these variables is y
Step 3
Combine to both GCF's to obtain the GCF of the expression.
= 6 × y
= 6y
The Greatest Common Factor for the expression 12x²y−6xy + 18y² is 6y
Step 4
We factorise
= 12x²y−6xy + 18y²
= 6y(2x² - x + 3y)
Therefore, Option c) Mike chose 6y because he said that it was the largest factor of every term is the correct option.
Mike is correct.

=11 = -17
Describe how you got the answer PLZS
Answers
Answer:
-17
Step-by-step explanation:
ok well I can't really see Sam and John's answer but -3-14 is equal to -17
if you see that there's a negative in front of the first number and its also subtracting you have to make that subtract sign an addition sign then change the second number to a negative like this:
-3+-14 then you just add.
With Sam and John whichever one had -17 as their answer is correct

1. A new pizza shop opened up and started out $6,378.60 in the hole. Their first month being open they
sold 56 pizzas ($6.63 profit each) and 91 sodas ($2.85 profit each). Their bills for the first month were
$1,547.76. How much money do they still need to make to break even?
Answers
Answer:
7212.53, i belive
Step-by-step explanation:
56 x 6.33 = 354.48
91 x 2.85 = 259.35
259.35 + 354.48 = 613.83
1547.76 - 613.83 = 933.93
6278.60 + 933.93 = 7212.53

The bases are the parallel line segments, and the height is the perpendicular distance between them.
A = (1/2)(7 m + 5 m)(3 m) = 1/2(12 m)(3 m) = 18 m^2
The area of the trapezoid is 18 square meters.

Karis receives $90000 per year working as a manager. She spends 15% every 3 month on her daughters college tuition. Write a function rule for the amount of money that Karis still has as a function of time in month
Answers
Answer:
[tex]f(m) = 90000 - 0.05m[/tex]
Step-by-step explanation:
Given
[tex]Base\ Amount = \$90000[/tex]
[tex]Spending = 15\%[/tex] -- every 3 months
Required
Determine the function that shows her monthly balance:
Represent month with m
If she spends 15% every 3 months;
Then
She spends 5% every month
i.e.
[tex]monthly = \frac{15\%}{3}[/tex]
[tex]monthly = 5\%[/tex]
If [tex]1\ month = 5\%[/tex]
Then
[tex]m\ months = 5\% * m[/tex]
Monthly balance (f(m) is then calculated as:
[tex]f(m) = Base\ Amount - Monthly\ Spending[/tex]
[tex]f(m) = 90000 - 5\% * m[/tex]
[tex]f(m) = 90000 - 0.05 * m[/tex]
[tex]f(m) = 90000 - 0.05m[/tex]

Now choose numbers that are the same and pair them together. These go outside the radicand. You had three 2’s and one 11. So a 2 would go on the outside and the remaining 2 and 11 would be multiplied leaved 2sqrt22.
Another way is to divide by the highest squared number. Taking sqrt88 again. 4 would be the highest squared number. So 88 would be 4 and 22, then 2 and 11. Since you have a 4 which is a perfect square you put that squareroot outside. The inside would remain the same because it wouldn’t break down into perfect squares or pairs anymore. So that would be 2sqrt22.

Line GH bisects angle FGI, that means angle FGH = angle HGI
To Find:the value of x and angle FGI
Solution:angle FGH = angle HGI
6x - 11 = 4x + 7
or, 6x - 4x = 7 + 11
or, 2x = 18
or, x = 18/2 = 9
angle FGI = angle FGH + angle HGI
or, angle FGI = 6x - 11 + 4x + 7
or, angle FGI = 10x - 4
By putting the value of x, we get
angle FGI = 10(9) - 4
or, angle FGI = 90 - 4 = 86°
Answer:The value of x is 9.
Angle FGI = 86°
