I need help on my 3.3.6 Journal: Breakdown Ahead apex.
Answer:
pg. 1
teresa: use difference of 2 squares
rico: 6561 is not a perfect square
pg. 2
i think teresa is right and that 6561 can be broken down
problem 1: (x^4-81)^2=(x^2-9)^4=(x-3)^8
problem 2: a. false b. rico
pg. 3
problem 3: a. -1(3x+5)^2 b. teresa is right because it cant still be a perfect square trinomial while having a negative first term.
problem 4: a. (y+3)^2 b. teresa
pg. 4
problem 5: a. (x^n+y^n)(x^n-y^n) b. teresa
teresa got more right, rico is buying pizza

i need help!! please help me!
Answer:
first table, the answer is -1
f(x)=x always rmmbr that so f(3)=-1 bcoz of the value 3 which represents the Term.
in second table, the values are at a 12 difference.
23-12=11, 11-12=-1,-1-12=-13, so -13-12=-25 and so on
second option is correct.

Jack has 80 marbles.
He gives 1/5 of the marbles to his friends. Work out how many marvels jack now has
Answer:
he has 64 marbles now
Step-by-step explanation:
Answer:
64 marbles
Step-by-step explanation:
1/5 = x/80
cross multiply
5 × x = 1 × 80
5x = 80
divide both sides by 5
x = 16
80 - 16

Answer:
uhm what? from how it looks its a multiplucation sign and 3 x 2 isnt 48 is 6 but 2 times 24 IS 48 and 3 times 16 IS 48
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
3 · x · 2 = 48
3 · 2 = 6
48 ÷ 6 = 8
3 · 8 · 6 = 48

A group of 3 friends were going on a hike. One friend brought 0.75 lbs of trail mix, the second friend brought 1.3 lbs of trail mix, and the third friend brought 0.35 lbs of trail mix. If they combine all their trail mix and split it equally among the 3 friends, how much trail mix does each friend get?
lbs
Answer:
0.8 pounds
Step-by-step explanation:
0.75 plus 1.3 plus 0.35 = 2.40 pounds
2.40 divided by 3 is 0.8 pounds

Jerry planted a pine tree that was 5 feet tall and a maple tree that was 10 feet tall. The pine tree grew 3 feet taller per year and the maple tree grew 2 feet taller per year. Which comparison is described by the inequality below? After x years, the pine tree is taller than the maple tree. After x years, the pine tree is at least as tall as the maple tree. After 3x years, the pine tree is taller than the maple tree was after 2x years. After 3x years, the pine tree is at least as tall as the maple tree was after 2x years.
The initial length of the pine tree=5 feet.
Groth rate of pine tree =3 feet/year.
The initial length of the pine tree =10 feet.
Groth rate of the maple tree =2 feet/year.
After x years, the height of the pine tree= 5+3x feet and
after x years, the height of the maple tree= 10+2x feet.
The inequality for which, after x year, the pine tree is taller than the maple tree is
[tex]5+3x>10+2x[/tex]
[tex]\Rightarrow x>5[/tex] .
The inequality for which, the pine tree is at least as tall as the maple tree is [tex]5+3x\geq10+2x[/tex].
[tex]\Rightarrow x\geq 5[/tex] .
Again, after 3x years, the height of the pine tree= 5+3(3x)=5+9x feet and
after 2x years, the height of the maple tree= 10+2(2x)=10+4x feet.
The inequality for which, after 3x years, the pine tree is taller than the maple tree was after 2x years is
[tex]5+9x>10+4x[/tex]
[tex]\Rightarrow 5x>5[/tex]
[tex]\Rightarrow x>1.[/tex]
The inequality for which, the pine tree is at least as tall as the maple tree is [tex]5+9x\geq10+4x[/tex].
[tex]\Rightarrow 5x\geq5[/tex]
[tex]\Rightarrow x\geq 1.[/tex]

2. there are two phone plans. One plan a $28 monthly fee, and cost 9 cents per minute. The second plan is 13 cents per minute, and $ 30 monthly fee.
A. Write and equations to represent the number of minutes use in a month that will make the plans cost the same?
B. Solbe the equation to find the number of minutes
_________________________________________________________________
3. cell phone plan costs per month for unlimited calling plus $0.15 per text message.
A. write a linear model that represents the monthly cost of this cell phone plan if the user sends t text messages
b. if you send 200 text messages, how much would you pay according to this cell phone plan?
Answer:
for the first one the answer is 28-9=18 and 30-13=17 are not the same but are close and for the second one the answer is $30 for the phone plan cause 200×0.15=30
If you use 50 minutes in a month, both plans will cost $32.50.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
2.
A. Let x be the number of minutes used in a month. Then, the cost of Plan A is given by:
Cost(A) = 0.09x + 28
The cost of Plan B is given by:
Cost(B) = 0.13x + 30
To find the number of minutes that will make the plans cost the same, we need to set Cost(A) equal to Cost(B) and solve for x:
0.09x + 28 = 0.13x + 30
0.04x = 2
x = 50
Therefore, the plans will cost the same if you use 50 minutes in a month.
B. If you use 50 minutes in a month, the cost of Plan A will be:
Cost(A) = 0.09(50) + 28 = 32.50
The cost of Plan B will also be:
Cost(B) = 0.13(50) + 30 = 36.50
Therefore, if you use 50 minutes in a month, both plans will cost $32.50.
3.
A. Let C be the monthly cost and t be the number of text messages sent. Then, the linear model that represents the monthly cost is:
C = 0.15t + base cost
The base cost is the cost for unlimited calling, which is not specified in the problem.
B. If you send 200 text messages, the monthly cost will be:
C = 0.15(200) + base cost
C = 30 + base cost
The total cost will depend on the base cost for unlimited calling.

Select the relationship between Angles 3 and 4
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
Angles 3 and 4 are Corresponding Angles, which is the second choice.
which of the following is equivalent formula?
Answer:
A
Step-by-step explanation:
S = (n - 2)180 (divide by 180 on both sides)
[tex]\frac{S}{180}[/tex] = n - 2 ( add 2 on each side)
[tex]\frac{S}{180}[/tex] + 2 = n

An object is traveling at a steady speed of 10 1/10 km/h. How long will it take the object to travel 1 9/10 km?
Answer:
It will take [tex]\frac{19}{101}[/tex] hour.
Step-by-step explanation:
The rule of the distance is:
Distance = speed × time
∵ An object is traveling at a steady speed of [tex]10\frac{1}{10}[/tex] km/h
∴ The speed = [tex]10\frac{1}{10}[/tex] km/h
∵ The object will travel [tex]1\frac{9}{10}[/tex] km
∴ The distance = [tex]1\frac{9}{10}[/tex] km
→ We need to find how long will it take it to travel this distance
→ Substitute the values of distance and speed in the rule above
∵ [tex]1\frac{9}{10}[/tex] = [tex]10\frac{1}{10}[/tex] × time
→ To find the time divide both sides by [tex]10\frac{1}{10}[/tex]
∴ The time = [tex]1\frac{9}{10}[/tex] ÷ [tex]10\frac{1}{10}[/tex]
→ Change the mixed numbers to an improper fraction
∵ [tex]1\frac{9}{10}[/tex] = [tex]\frac{(1)(10)+9}{10}=\frac{19}{10}[/tex]
∵ [tex]10\frac{1}{10}=\frac{(10)(10)+1}{10}=\frac{101}{10}[/tex]
∴ The time = [tex]\frac{19}{10}[/tex] ÷ [tex]\frac{101}{10}[/tex]
- Reverse the fraction after the division sign, then change ÷ to ×
∴ The time = [tex]\frac{19}{10}[/tex] × [tex]\frac{10}{101}[/tex]
→ 10 up will cancel 10 down
∴ The time = [tex]\frac{19}{101}[/tex] h
It will take [tex]\frac{19}{101}[/tex] hour.

Write an equation of the line that passes through (1, 2) and is perpendicular to the line y = 1/3x+4. An equation of the perpendicular line is
y = ?
Answer:
I'm not sure but I believe its y=-3x+5
Step-by-step explanation:
You start off by finding slope which is -1/m. So 1/1/3=-3. From here you plug in the variables (1,2) and solving. The equation becomes y=-3x+b. From here plug in x and y. So, 2=-3+b. From here add 3 to both sides and you get 5=b. Then just put it together. y= -3x+5

JL = 55, and
JK = 7* +8,
Find KL.
J
K
L
Answer:
KL = 12Step-by-step explanation:
JK + KL = JL
where:
JK = 7x + 8
KL = 2x + 2
JL = 55
plugin values into the equation:
7x + 8 + 2x + 2 = 55
7x + 2x = 55 - 8 - 2
9x = 45
x = 45 / 9
x = 5
KL = 2x + 2
KL = 2(5) + 2
KL = 12
