(100 points) Match each ordered pair on the left with the functions on the right
Answers
Answer:
(6, 1) ⇒ y = 2/4x - 2
(-8, -0.8) ⇒ y = 3/5x + 4
(9, 0.7) ⇒ y = 3/10x - 2
(2, 7.4) ⇒ y = 1/5x + 7
Step-by-step explanation:
Let's substitute each pair in the equations to find the right one :
(6, 1)
⇒ 1 = 2/4 (6) - 2
⇒ 1 = 3 - 2
⇒ 1 = 1
⇒ Equation matched √
(6, 1) ⇒ y = 2/4x - 2
(-8, -0.8)
⇒ -0.8 = 1/5 (-8) + 7
⇒ -0.8 = -8/5 + 7
⇒ -0.8 = -1.6 + 7
⇒ -0.8 = 5.4
⇒ Incorrect equation ×
⇒ -0.8 = 3/5 (-8) + 4
⇒ -0.8 = -24/5 + 4
⇒ -0.8 = -4.8 + 4
⇒ -0.8 = -0.8
⇒ Equation matched √
⇒ (-8, -0.8) ⇒ y = 3/5x + 4
(9, 0.7)
⇒ 0.7 = 3/10 (9) - 2
⇒ 0.7 = 27/10 - 2
⇒ 0.7 = 2.7 - 2
⇒ 0.7 = 0.7
⇒ Equation matched √
⇒ (9, 0.7) ⇒ y = 3/10x - 2
(2, 7.4)
⇒ 7.4 = 1/5 (2) + 7
⇒ 7.4 = 2/5 + 7
⇒ 7.4 = 0.4 + 7
⇒ 7.4 = 7.4
⇒ Equation matched √
⇒ (2, 7.4) ⇒ y = 1/5x + 7

Answer:
[tex]\large\boxed{\sf{x=45}}[/tex]Step-by-step explanation:
Given:
Complementary angles of 180 degrees.To solve:
For x, to isolate it one side of the equation.(3x)°+45°=180°
3x+45=180First, subtract by 45 from both sides.
3x+45-45=180-45
Solve.
Subtract these numbers goes from left to right.
180-45=135
3x=135
Divide by 3 from both sides.
3x/3=135/3
Solve.
Divide these numbers from left to right.
135/3=45
[tex]\Longrightarrow: \boxed{\sf{x=45}}[/tex]
Therefore, the final answer is x=45.I hope this helps, let me know if you have any questions.

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 216, 36,6 Find the 8th term.
Answers
Answer:

Step-by-step explanation:
Given (or we can find) :
First term : 216
Common ratio : 36/216 = 1/6
To find 8th term :
a₈ = ar⁸⁻¹
a₈ = (216)(1/6)⁷
a₈ = 216/279936
a₈ = 6³/6⁷
a₈ = 1/6⁴
a₈ = 1/1296
a₈ = 0.000771604938

Answer:
0.9 kg of chocolate and 2.1 kg of peanut butter
Step-by-step explanation:
Since we know Ms. G is making 3 kg of peanut butter cups we can remove one of the variables. I will say that p = (3 - c) since anything in the 3 kg that isn't chocolate is peanut butter.
We can now find the total cost of the peanut butter cups.
3kg * $9.55/kg = $28.65
We can now set up an equation to find how much chocolate was bought.
8.50(3 - c) + 12(c) = 28.65 | distributive property
25.5 - 8.5c + 12c = 28.65 | subtract 25.5 from both sides
3.5c = 3.15 | divide both sides by 3.5
c = 0.9
This means 0.9 kg of chocolate was bought. Now we can solve for the amount of peanut butter purchased.
p = (3 - c)
p = (3 - 0.9)
p = 2.1
This means 2.1 kg of peanut butter was bought.
That is the answer

Answers
Answer:
[tex]\large\begin{cases}a_1=5 \\a_n=a_{(n-1)}-4\end{cases}[/tex]
Step-by-step explanation:
Recursive formula allows us to find the value of a specific term based on the previous term.
Explicit formula allows us to find the value of a specific term based on its position.
Given explicit formula: [tex]a(n)=5+(n-1)(-4)[/tex]
[tex]\implies a(1)=5+(1-1)(-4)=5[/tex]
[tex]\implies a(2)=5+(2-1)(-4)=1[/tex]
[tex]\implies a(3)=5+(3-1)(-4)=-3[/tex]
[tex]\implies a(4)=5+(4-1)(-4)=-7[/tex]
From inspection of the sequence, we can see that to get the next term, we need to subtract 4 from the previous term.
[tex]5 \underset{-4}{\longrightarrow} 1 \underset{-4}{\longrightarrow} -3 \underset{-4}{\longrightarrow} -7[/tex]
Therefore, the recursive formula is:
[tex]a_n=a_{(n-1)}-4[/tex]
For a recursive formula, we also need to give the value for [tex]a_1[/tex] .
Therefore, the final recursive formula for the explicit formula is:
[tex]\large\begin{cases}a_1=5 \\a_n=a_{(n-1)}-4\end{cases}[/tex]

Answers
Using proportions, the amount of money that Sam would need each month to pay his bills is of:
b. at least $425.32.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, his annual social security benefit is of 42% of $37,991, hence:
A = 0.42 x 37991 = $15,956.22.
Hence the monthly amount is given by:
M = 15956.22/12 = $1,329.68
He needs $1,755 monthly, hence the amount he needs is of at least:
An = 1755 - 1329.68 = $425.32.
