Answer:
Part A: The slope f(x) is greater than slope g(x).
Part B: f(x) has a greater y-intercept.
Step-by-step explanation:
Part A:
The slope of the line is (y2 - y1)/(x2 - x1), so now we have to find the slope f(x).
-1 - (-9) / 0 - (-1) = 8/1 = 8
That would be the slope, and for g(x) it would be 3x-2 = 3.
Which means the slope f(x) is greater than slope g(x).
Part B:
First the y-intercept has to be put on 0.
So, the when function f(x) passes through point (0, -1), then y-intercept is -1.
Now we compare g(x) = 3x-2 with the slope-intercept form and b = -2 is the result. form and b = -2 is the result.
Which means the slope of g(x) is -2. Therefore, f(x) has a greater y-intercept than g(x).
Answer:
A) Slope of f(x) is 8. Slope of g(x) is 3
B) f(x) has the greater y-intercept
Step-by-step explanation:
Part A
To find the slope of function f(x), use the slope formula:
[tex]\sf slope\:(m)=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{7-(-1)}{1-0}=8[/tex]
Therefore, the slope of f(x) is 8.
Linear function
[tex]y=mx+b[/tex]
where:
m is the slopeb is the y-interceptGiven:
[tex]g(x)=3x-2[/tex]Therefore, the slope of g(x) is 3.
Part B
The y-intercept is when x = 0. Therefore, from inspection of the table, the y-intercept of f(x) is -1.
The y-intercept of function g(x) is -2.
Therefore, as -1 > -2, function f(x) has the greater y-intercept.

First paragraphThe roots of the quadratic function describing the relationship between number of products produced and overall profit margin are x = 0 and x = 100. The vertex is (50, 1000).
The maximum profit of $ 50 is reached when 1000 items are produced.
The first root tells us that the profit will be 0 when 0 products are produced. The second root says once 1000 items are made, the company is no longer making any profit. (They do not have production capacity and have to outsource for anything over 50)

Find the area of this figure! (Don’t give me a big explanation, i have 30 mins to get this ixl to 90, currently at 74)
315 m²
area of rec + area of rec + area of rec + area of triangle
⇒ length + width + length + width + length + width + 1/2 * base * height
⇒ 19 * 6 + 9 * 9 + 18 * 5 + 1/2 * 12 * 5
⇒ 90 + 30 + 81 + 114
⇒ 315 m²
Answer:
315 m²
Step-by-step explanation:
As this figure may seem complicated, we can split it into four separate figures.
Area
Area of vertical rectangle + Area of left horizontal rectangle + Area of right horizontal rectangle + Area of triangle6 x 10 + (9 + 6) x (19 - 10) + 18 x 5 + 1/2 x 12 x (18 + 9 + 6 - 17 - 11)60 + 15 x 9 + 90 + 6 x 560 + 135 + 90 + 30180 + 135315 m²The vertices of a rectangle are E(−1, 1), F(−1, 3), G(−5, 3), and H(−5, 1). Find the coordinates of the figure after reflecting in the x-axis, and then translating 3 units right.
The resulting points of the rectangle after applying rigid transformations are E'(x, y) = (2, -1), F(x, y) = (2, -3), G(x, y) = (-2, -3), H(x, y) = (-2, -1).
How to apply rigid transformations on geometrical loci
Rigid transformations are transformations in which Euclidean distances are conserved in every point of the geometrical locus. Reflections and translations are sound examples of rigid transformations.
Based on all the information given in the statement, we must apply the following vectorial formula to each vertex of the rectangle EFGH:
(x', y') = (x + 3, -y) (1)
If we know that E(x, y) = (-1, 1), F(x, y) = (-1, 3), G(x, y) = (-5, 3) and H(x, y) = (-5, 1), then the new coordinates are calculated below:
E'(x, y) = (2, -1), F(x, y) = (2, -3), G(x, y) = (-2, -3), H(x, y) = (-2, -1)

Juan has $640 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
He buys a new bicycle for $265.36.
He buys 2 bicycle reflectors for $13.61 each and a pair of bike gloves for $37.11.
He plans to spend some or all of the money he has left to buy new biking outfits for $54.87 each.
What is the greatest number of outfits Juan can buy with the money that's left over?
Answer:
Juan can buy 6 outfits with the money that's left over.
Step-by-step explanation:
Take $640-$265.36-$13.61-$37.11 and then divide
the answer, $332.92 by $54.87.
Juan spent a total of $316.08 on the bicycle, reflectors, and gloves. With the remaining $323.92, he can buy a maximum of 6 biking outfits priced at $54.87 each.
Given that,
Juan has $640 to spend at a bicycle store for new gear and biking outfits.
He buys a new bicycle for $265.36.
He buys 2 bicycle reflectors for $13.61 each.
He buys a pair of bike gloves for $37.11.
To determine the greatest number of outfits Juan can buy with the money he has left,
Calculate the remaining amount after purchasing the bicycle, reflectors, and gloves.
Juan's initial budget is $640.
After buying the bicycle for $265.36, the remaining amount is,
$640 - $265.36 = $374.64.
Next, he buys 2 bicycle reflectors for $13.61 each, which is a total of
2 x $13.61 = $27.22.
Subtracting this amount from the remaining budget, we have
$374.64 - $27.22 = $347.42.
Additionally, he purchases a pair of bike gloves for $37.11, leaving him with $347.42 - $37.11 = $310.31.
Finally, dividing the remaining budget by the cost of each biking outfit, which is $54.87,
Then Juan can buy a maximum of $310.31 / $54.87 ≈ 6 outfits.
Therefore, the greatest number of biking outfits Juan can buy with the money left over is 6.

the ratio of the 6th and 8th term of an ap is 7:9. find the ratio between the sum of its first 10 terms to sum of its first 20 terms
Step-by-step explanation:
Tn = a + (n-1)d
where a is the first term, d is the common difference and n is the nth term
For the 6th term: T6 = a + (6-1)d
= a + 5d
For the 8th term: T8 = a + (8-1)d
= a + 7d
From the question (a + 5d)/(a + 7d) = 7/9
From the Equation above, we can say that;
a + 5d = 7......1
a + 7d = 9.....2
Solving equations 1 & 2 simultaneously, we have that a = 2 and d = 1
Sn = n/2[2a + (n-1)d]
where Sn is the sum of nth terms, n is the nth term, a is the first term and d is the common difference.
By substituting the values gotten into this equation. You would be able to find the ration between the sum of the first 10 terms to the sum of the first 20 terms

2.5 percent to a decimal is 0.025
6,439.65 × 0.44 = 2833.446 (within 15 days)
6,439.65 × 0.025 = 160.99125 (within 30 days)

17. Instructions: Use the ratio of a 45-45-90 triangle to solve for the variables. Leave your answers as radicals in simplest form.
Answer:
u = v = 14
Step-by-step explanation:
The ratios of side lengths in a 45-45-90 triangle are ...
1 : 1 : √2
Here, the long side is 14√2, so is 14 times this basic ratio.
1 : 1 : √2 = u : v : 14√2 = 14 : 14 : 14√2
This means ...
u = v = 14
Answer:
Below in bold.
Step-by-step explanation:
The ratio of the sides in a 45-45-90 are 1:1:√2.
so V / 14√2 = 1 / √2
V = 14√2 / √2 = 14.
and U = V = 14 also.

Nadia walks at an average speed of (x + 2) km/h for (x – 3) hours and cycles at an average speed of (3x + 5) km/h for x hours. She covers a total distance of 74 km. (i) Form an equation in x and show that it reduces to 4x2 + 4x - 80 = 0. (ii) Solve the equation 4x2 + 4x – 80 = 0. (iii) Find the time taken for her entire journey.
The time taken by Nadia for her entire journey is 5 hours
Speed and distance
Speed is the rate at which an object is moving, and it is defined as the distance traveled per unit of time. The formula for speed is:
Speed = Distance/Time
Where distance is the distance traveled by an object and time is the time taken to travel that distance.
From the fomrula, we can write as
Distance = Speed × Time
Here we have
Nadia walks at an average speed of (x + 2) km/h for (x – 3) hours and cycles at an average speed of (3x + 5) km/h for x hours.
As we know, Distance = Speed x Time
Distance walked = (x + 2)(x - 3)
Distance cycled = (3x + 5)(x)
The total distance covered is given as 74 km,
=> (x + 2)(x - 3) + (3x + 5)(x) = 74
=> x² - 3x + 2x - 6 + 3x² + 5x = 74
=> 4x² + 4x - 80 = 0
Hence, the final equation is 4x² + 4x - 80 = 0
(ii) The quadratic equation, can be solved as follows
=> x² + x - 20 = 0
=> x² + 5x - 4x - 20 = 0
=> x(x + 5) -4(x + 5) = 0
=> (x + 5) (x - 4) = 0
=> x = - 5 and x = 4
Here we cant take time as negative so take x = 4 hours
(iii) To find the time taken for her entire journey, we need to add up the time taken for walking and cycling:
Total time = (x - 3) + x
Total time = 2x - 3
Substituting the value of x
Total time = 2(4) - 3 = 8 - 3 = 5
Therefore,
The time taken by Nadia for her entire journey is 5 hours
