Answer:
t(n) = -7.1 - 2.1n
t(27) = -7.1 - 2.1(27)
t(27) = -7.1 - 56.7
t(27) = -63.8
for the n term 1,2,3,4,5 you can use it like previous I have done

1. Find a line that is parallel to f(x) = 2x +3 and passes through (0,-4).
2. Find through line that is perpendicular to f(x) = 2x+3 and passes through (0,-4)
Answer:
1)The equation of the Parallel line is 2x -y -4=0
2) The equation of the perpendicular line of the given line x+2y+8=0
Step-by-step explanation:
Step(i):-
Given function f(x) = 2x+3 and passes through (0,-4)
Let y =f(x) = 2x+3
y = 2x+3
⇒ 2x -y +3=0
The equation of the parallel line of the given line 2x - y +k =0
This line is passes through the point (0,-4)
⇒ 2 (0) -(-4)+k=0
4 +k=0
⇒ k =-4
The equation of the Parallel line is 2x -y -4=0
2)
Step(ii):-
Given function f(x) = 2x+3
Let y = 2 x + 3
2x - y +3=0
The equation of the perpendicular line bx -ay +k=0
The equation of the perpendicular line of the given line -x-2y +k =0
This line is passes through the point (0,-4)
⇒ (0) -2(-4)+k=0
8 +k=0
⇒ k =-8
The equation of the perpendicular line of the given line -x-2y -8 =0
The equation of the perpendicular line of the given line x+2y+8=0

URGENT: A grocer has 150 kg of walnuts that sell for $6 per kg. She plans to add almonds that sell for $5.30 per kg to the walnuts to make a mixture that sells for $5.50 per kg. How many kg of almonds should she add? (MUST SHOW WORK)
Answer:
let c = cashew pounds, w = walnut pounds, m = mixed pounds
Here's what we know:
c + w = m
7c + 5.5w = 6.50m
m = 35
So we now have:
c + w = 35
7c + 5.5w = 227.5
We can use substitution or elimination here. Let's try substitution in this case:
c = 35 - w
7(35 - 7) + 5.5w = 227.5
245 - 7w + 5.5w = 227.5
245 - 1.5w = 227.5
-1.5w = -17.5
w = 11 2/3
Now to solve for cashews:
c = 35 - 11 2/3
c = 23 1/3
Check:
23 1/3 * 7 + 5.5 * 11 2/3 = 227.5
163 1/3 + 64 1/6 = 227.5
163 2/6 + 64 1/6 = 227.5
227 3/6 = 227.5
227.5 = 227.5

Drew and Larry are working together on a jigsaw puzzle. Drew places 11 less than 3 times the number of pieces that Larry places. Drew places at least 10 pieces. How many pieces does Larry place?
Answer:
Larry places 19 puzzles
Step-by-step explanation:
Step one:
given data
let the number of puzzles Larry places be x
and let the number of puzzles Drew places be y
so
y=3x-11
Step two:
We are told that Drew places at least 10
so for x= 10
y= 3*10-11
y=30-11
y=19

20 POINTS URGENT! PLEASE HELP! FAKE ANSWERS REPORTED!
Answer:
AD=35
Step-by-step explanation:
The difference between FJ-GH is equal to the difference between EK-FJ
Lets call this difference "D"
so
(7x+2)-(8x-7)=D
simplifying
7x+2-8X+7=D
-x+9=D
(10x-1)-(7x+2)=D
simplifying
10x-1-7x-2=D
3x-3=D
now D=D so
-x+9=3x-3
12=4x
x=3
solving each known line equation for x:
8(3)-1=17
7(3)+2=23
10(3)-1=29
The line gets longer each time by 6
AD=EK+6=35

Answer: 2y - 9.5
Step-by-step explanation:
3(1/2y -2.5) + 2(3/12y - 1) First distribute
3/2y - 7.5 + 6/12y - 2 Combine like terms
18/12y + 6/12y - 7.5-2
24/12y - 9.5
2y - 9.5

Step-by-step explanation:
Since, both the Pentagons are similar. So, their corresponding sides would be in proportion.
Therefore,
[tex] \frac{4}{4x} = \frac{(x + 2)}{48} \\ \\ \frac{1}{x} = \frac{(x + 2)}{48} \\ \\ x(x + 2) = 48 \\ \\ {x}^{2} + 2x = 48 \\ \\ {x}^{2} + 2x - 48 = 0 \\ \\ {x}^{2} + 8x - 6x - 48 = 0 \\ \\ x(x + 8) - 6(x + 8) = 0 \\ \\ (x + 8)(x - 6) = 0 \\ \\ x + 8 = 0 \: \: or \: \: x - 6 = 0 \\ \\ x = - 8 \: \: or \: \: x = 6 \\ \\ \because \: x \: cannot \: be \: - ve \\ \implies \: x = 6[/tex]

A certain prescription has a 0.15 cc dosage tolerance factor in its liquid form. If a doctor prescribes 2.4 cc of medication, find the upper and lower limits of the amount of medication that should be given to the patient. Do not round your answer.
Answers:
Upper Limit = 2.55 cc
Lower Limit = 2.25 cc
cc stands for "cubic centimeters".
==========================================
Explanation:
The tolerance tells us how much we can go over or under our target. It's our margin of error. We add and subtract the tolerance (0.15) from the target we're trying to aim for (2.4)
So the lowest dosage allowed is 2.4-0.15 = 2.25 cc
The highest dosage allowed is 2.4+0.15 = 2.55 cc
The upper limit is 2.55 cc while the lower limit is 2.25 cc
On a number line, we would find that 2.4 is at the midpoint of 2.25 and 2.55; so its at the center of those lower and upper bounds. The distance from the center to each endpoint is the same. That distance would be the tolerance 0.15
