Answer: y = (1/3)x - 3
Step-by-step explanation:
It passes through -3 at 0, so we know the y = mx + b form will include -3
Next, we want to find the slope:
Change in y = 0 - -3 = 3
Change in x = 9 - 0 = 9
Change in y / Change in x = slope
3/9 = 1/3

The multiplication of the mixed fractions as 4²/₇ * 2¹/₅ gives; 9³/₇
How to multiply mixed fractions?A mixed fraction is one that has a part that is a whole number and a part that is a proper fraction.
Now, a proper fraction has its' numerator lesser than its' denominator while an improper fraction has it's numerator greater than its' denominator.
Let us convert each fraction into an improper fraction before multiplication.
4²/₇ = 30/7
2¹/₅ = 11/5
Thus, we have;
30/7 * 11/5
This can be reduced to;

By using the Unitary method, $468 was spent on newspapers in 52 weeks.
Unitary method is a method used for finding the unit cost in which we divide the total cost by the total number of articles and to find the cost of more than one article, we multiply the unit cost by the number of articles required.
Cost of newspapers in a week from monday to saturday = $(1 x 6) = $6

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices.
What is meant by angles?An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. It is referred to as dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves.Angle can also refer to the length of a rotation or an angle. This metric represents the relationship between a circular arc's length and radius.The arc is centered at the vertex and defined by the sides in the case of a geometric angle. When there is a rotation, the arc is defined by any other point and the rotation's image, and it is centered at the rotation's center.10. In the given figure,

(3x - 29)° + (8y + 17)° = 180° [Because they are linear pairs]
⇒ 3x -29 + 8y + 17 = 180
⇒ 3x + 8y - 12 = 180
⇒ 3x + 8y = 192 ............ (1)
Now,
8y + 17 = 6x -7 [Alternate interior angles]
⇒ 6x - 8y = 24 ..............(2)
On adding (1) and (2),
(3x + 8y) + (6x - 8y) = 192 + 24
simplifying the above equation, we get
⇒9x = 216
⇒ x = 216/9 = 24
⇒ x = 24
Now, 6x - 8y = 24
⇒ 8y = 6(24) - 24
⇒ y = (144 - 24)/8
⇒ y = 120/8 = 15
So, x = 24 and y = 15

Initially, there were only 4 weeds at a park. The weeds grew at a rate of 15% each week. The following function represents the weekly weed growth: f(x) = 4(1.15)x. Rewrite the function to show how quickly the weeds grow each day and calculate this rate as a percentage.
f(x) = 4(1.15)7x; spreads at a rate of approximately 1.5% daily
f(x) = 4(1.02)7x; spreads at a rate of approximately 2% daily
f(x) = 4(1.157)x; spreads at a rate of approximately 2.66% daily
f(x) = 4(1.02)x; spreads at a rate of approximately 0.2% daily
The function to show how quickly the weeds grow each day is "f(x) = 4(1.02)7x; spreads at a rate of approximately 2% daily. Option B
How can we figure out the rate of increase in percentage terms each day?f(x) = 4(1.15)x = 4(1+ 0.15)x ................... (1)
Given that there are seven days in a week, the daily growth rate of the weeds may be estimated using equation (1) by dividing 0.15 (which stands for the 15% weekly growth rate) in the following manner:
f(x) = 4(1.15)x = 4(1+ 0.15/7)x
f(x) = 4(1 + 0.02)x
f(x) = 4(1.02)x

Serena’s father tipped a taxi driver $5 for a $25 ride. What was the percent of the tip that he paid?
The percentage of the tip that Serena's father paid was 20%.
What is a percentage?Mathematically, a percentage is a numerical ratio, usually expressed as a fraction of 100 and denoted by the percent sign (%).
Percentages show the proportional relationship between two fractions, like proportions and ratios.
The amount of the tip = $5
The cost of the ride = $25
The total amount paid by Serena's father = $30 ($5 + $25)
The percentage of tip to the ride's cost = The amount of the tip divided by the cost of the ride.

Answer:

Step-by-step explanation:
In this picture we can see that they gave us 2 angles.
Angle V has an angle of x+83
Angle S has an angle of 4x - 53
As one of the circle thermoses in mathematics said when there is an angle in the center of the circle, the angle at the circumference is half the angle at the center, which means we could create and equation such that:
angle of angle V = 2 times the angle of angle S
x + 83 = 2(4x - 53)
x + 83 = 8x - 106
189 = 7x
27 = x
Since we know x = 27, we can substitute into the equation angle of S to find what is the angle of TSU:
4x - 53
= 4(27) - 53
= 108 - 53
= 45
Answer:
<TSU = 55°
Step-by-step explanation:
We know that,
Angle at the circumference of a circle is twice the angle at the centre.
Therefore,
2 × <UST = <UVT
Given that,
< UVT = x + 83
< TSU = 4x - 53
Accordingly, we can make an expression like this.
[tex] \sf2 × <UST = <UVT[/tex]
[tex] \sf2(4x - 53) = x + 83 \\ [/tex]
And now solve the above expression and find the value of x.
Let us solve it now.
[tex] \sf8x - 106 = x + 83 \\ \sf8x - x = 106 + 83 \\ \sf7x = 189 \\ \sf \: x = 27[/tex]
And now, according to the question they've asked us to find the value of <TSU.
As we mentioned earlier, they've given that, <TSU = 4x - 53.
So, to find the value of Angle TSU, we have to replace x with 27 and find the value of angle TSU.
Let us solve it now
[tex] \sf \: <TSU = 4x - 53 \\ \sf \: <TSU = 4 \times 27 - 53 \\ \sf \: <TSU = 108 - 53 \\ \sf \: <TSU = 55 \degree[/tex]

Applying the slope formula, we have:
16. Slope = -9/4; Parallel slope = -9/4; Perpendicular slope = 4/9.
17. Slope = -4; Parallel slope = -4; Perpendicular slope = 1/4.
See explanation below for the rest answers.
How to Find the Slope of a Line?Slope of a line = change in y / change in x.
The slope of parallel lines are the same, while the slopes of two lines that are perpendicular to each other are negative reciprocals of each other, i.e. 1/a and -a can be the slopes of two lines that are perpendicular to each other.
In an equation given in slope-intercept form, y = mx + b, the slope is represented as "m".
16. Given, (3, 7) and (7, -2):
Slope (m) = (-2 - 7)/(7 - 3)
Slope = -9/4
Parallel slope = -9/4
Perpendicular slope = 4/9.
17. Given, y = -4x + 2,
Slope = -4
Parallel slope = -4
Perpendicular slope = 1/4.
18. Rewrite 5x - 2y = 8 in slope-intercept form:
-2y = -5x + 8
y = 5/2x - 4
Slope = 5/2
Parallel slope = 5/2
Perpendicular slope = -2/5.
19. Rewrite 4x + 3y = 2 in slope-intercept form:
3y = -4x + 2
y = -4/3x + 2/3
Slope (m) = -4/3
Substitute (a, b) = (2, -5), and m = -4/3 into y - b = m(x - a):
y - (-5)) = -4/3(x - 2)
y + 5 = -4/3(x - 2) [point-slope form]
20. Given, y = -5x + 2
Slope (m) = -5
Substitute (a, b) = (-4, -6), and m = -5 into y - b = m(x - a):
y - (-6) = -5(x - (-4))
y + 6 = -5(x + 4) [point-slope form]
21. Rewrite 9x - 3y = 6 in slope-intercept form:
-3y = -9x + 6
y = 3x - 2
The slope of y = 3x - 2 (9x - 3y = 6) is 3.
The slope of -3x - 5 is -3.
