The equation in slope-intercept form of the line that passes through the point (3,4) and is parallel to the line represented by y=3x−2 is y = 3x - 5.
How to represent equation in slope intercept form?The equation of a line can be represented in slope intercept form, point slope form, standard form and general form.
Linear equation in slope intercept form is as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the line that passes through the point (3,4) and is parallel to the line represented by y = 3x −2.
parallel lines have the same slope.
Therefore, the slope of the line is 3.
The y-intercept can be found as follows:
using (3, 4)
y = 3x + b
4 = 3(3) + b
b = 4 - 9
b = -5
Therefore, the equation in slope intercept form is y = 3x - 5.

What’s the answer to 8 and 9
Answer: 4 red and 12 blue
Step-by-step explanation: Answer to 9
We know that for every red rose, he plants 3 blue flowers. The rate is 1:3. If he grows 16, there will be 4 red roses and 12 blue ones. This is because the rate is 1:3 then there are 4 flowers in all. This is 1/4 of how much he wants to grow. So multiply each type of plant by 4. 1 times 4 is 4, so there are 4 red ones. 3 times 4 is 12, so there are 12 blue ones. Hope this helps!

(a) give the order in which the vertices of the tree are visited in a post-order traversal. (b) give the order in which the vertices of the tree are visited in a pre-order traversal.
Answer:
post-order: f, i, h, e, b, g, c, a, dpre-order: d, f, b, i, h, e, a, c, gStep-by-step explanation:
You want the (a) post-order, and (b) pre-order list of visited vertices in a traversal of the tree described by {root, left, center, right}: {d, f, {b, i, h, e}, {a, {c, g}}}.
(a) Post-orderA tree is traversed in post-order by visiting the left branch, center branch, and right branch before the root. This is accomplished recursively.
For the given tree, the root 'd' has left branch 'f' which has no branches. That means node 'f' is reported first.
The middle branch goes to 'b' which has three branches. Those are reported before their root 'b'.
The right branch from root 'd' goes to 'a', which has branch 'c' going to 'g'. So, 'g' is reported, then 'c', then 'a'.
Finally, 'd' is reported.
Hence, the post-order traversal is f, i, h, e, b, g, c, a, d.
(b) Pre-orderThe pre-order traversal reports the root node, then the left, center, and right nodes, recursively. The vertices are effectively visited in the order in which we have defined the tree above: d, f, b, i, h, e, a, c, g.

Import duties, in addition to being a source of revenue for the government, can also be a form of foreign trade regulation and policy that taxes foreign products in order to encourage or safeguard domestic industry.
Tariffs serve three primary functions: they generate revenue, they protect domestic industries, and they correct trade distortions (punitive function).

Estimate a 10 % tip on a bill of $159.67 by first rounding the bill amount to the nearest ten dollars.
Answer: $180
Step-by-step explanation: To calculate the total tip, you would add 10% to the bill,
Total bill = $159.67 x 1.10+ 175.637 or $175.64
$175.64 rounded to the nearest $10 dollars is $180 as the number in the 1s column is greater than 5. Because of this, you round up to get the nearest $10.

Write the explicit and recursive rules for a geometric sequence given a table of values.
(a) The Explicit Rule for f(n) is 0.1 × 3n The Recursive Rule for f(n) is f(n-1) × 3. (b) The Explicit Rule for f(n) is 100 × 0.1ⁿ The Recursive Rule for f(n) is f(n-1) × 0.1
What is Explicit rule ?The explicit rule states that the value of the sequence at each term is 0.1 multiplied by 3 raised to the power of n. The recursive rule states that the value of the sequence at each term is equal to the value of the preceding term multiplied by 3. This can be seen in the table of values where each value is 3 times the preceding value.
Given,
n = 0,1,2,3,4…
f(n) = 0.1,0.3, 0.9, 2.7, 8.1
(b) The Explicit Rule for f(n) is 100 × 0.1ⁿ, The Recursive Rule for f(n) is f(n-1) x 0.1
Given,
n= 0,1,2,3,4..
f(n) = 100, 10, 1,0.1, 0.01
The explicit formula is the formula to calculate the value of the sequence directly without using any previous terms. The recursive formula uses the previous term to calculate the value of the current term.
In this example, the explicit formula is 100 × 0.1ⁿ and the recursive formula is f(n) = f(n-1) × 0.1. This means that each term in the sequence is equal to the previous term multiplied by 0.1.
For example, the third term in the sequence is 1, so the fourth term is 1 × 0.1 = 0.1.
(c) The Explicit rule for f(n) is 1000 × 0.1⁽ⁿ ⁻ ¹⁾, The Recursive rule for f(n) is f(n-1) x 0.1
To solve,
f(5) = 1000 × 0.1⁽⁵ ⁻ ¹⁾(5-1)
= 1000 × 0.1⁴
= 1000 × 0.0001
= 0.1
Given,
n= 1,2,3,4,5…
f(n) = 1000, 100, 10, 1, 0.1
The explicit and recursive rules for this geometric sequence are both written as f(n) = 1000 × 0.1⁽ⁿ ⁻ ¹⁾. This means that the value of the sequence at any given point n will be equal to 1000 multiplied by 0.1 raised to the power of n-1. This means that the value of the sequence decreases by a factor of 0.1 for every increase in n.
In this case,
f(5) = 1000 x [tex]0.1^4[/tex]
= 0.1.
(d) The Explicit Rule for this geometric sequence is f(n) = 10⁽⁵⁰ ⁻ ³ⁿ⁾, where n is the term number of the sequence.
The Recursive Rule for this geometric sequence is f(n) = f(n-1) ÷ 10³, where f(n) is the value for the nth term of the sequence and f(n-1) is the value for the (n-1)th term of the sequence.
Given,
n= 1,2,3,4,5..
f(n) = 10⁵⁰,10⁴⁷, 10⁴⁴, 10⁴¹, 10³⁸….
The value for the 5th term of the sequence is f(5) = 10⁽⁵⁰ ⁻ ³⁽⁵⁾⁾ = 10³⁸. The explicit rule for this geometric sequence is f(n) = 10⁽⁵⁰ ⁻ ³ⁿ⁾, where n is the term number of the sequence. This means that the value of each term is determined by taking 10 to the power of 50 minus 3 multiplied by the term number.
The recursive rule for this geometric sequence is [tex]\frac{f(n-1)}{10^3}[/tex] which means that the value of each term can be calculated by dividing the previous term by 10 cubes. We can use

Tyshawn took a taxi from his house to the airport. The taxi company charged a pick-up fee of $2.50 plus $3.50 per mile. The total fare was $79.50, not including the tip. Which equation could be used to determine mm, the number of miles in the taxi ride?
Answer: m = 22
Step-by-step explanation:
First, you subtract $2.50 from the total of $79.50 (because that is the static fee) to get $77.00. Now, because every mile is $3.50 and we want to find the number of miles, we divide $77 by $3.50 to get 22. (An easy way to do this mentally is to divide 77 by 7 and multiply by 2.) Therefore, m = 22.

Answer:
[tex] \sf \: 2x + 3 = 9, \: x = 3[/tex]
Step-by-step explanation:
Given statement,
→ Sum of 2 times a number & 3 is 9.
Let the unknown number be,
→ [tex] \sf \pink{x}[/tex]
Forming the equation,
→ (2 × x) + 3 = 9
→ 2x + 3 = 9
Now the value of x will be,
→ 2x + 3 = 9
→ 2x = 9 - 3
→ 2x = 6
→ x = 6/2
→ [ x = 3 ]
Hence, the value of x is 3.
