Write the equation of the line that is parallel to y=-0.75x and that passes through the point (8,0)
The equation of the line that is parallel to y=-0.75x and passes through the point (8,0) is y = -0.75x + 6.
Explanation:The equation of a line in the form y = mx + b represents a linear equation, where m is the slope of the line and b is the y-intercept. Since we are looking for a line parallel to y = -0.75x, we know that the new line will have the same slope. So, the equation of the new line is y = -0.75x + b. To find the value of b, we can substitute the coordinates of the point (8,0) into the equation and solve for b.
0 = -0.75(8) + b
0 = -6 + b
b = 6
Therefore, the equation of the line that is parallel to y = -0.75x and passes through the point (8,0) is y = -0.75x + 6.
Consider the following equations: f(x) = 2x – 2 and g(x) = 5 - x
a. The two equations represent lines on a graph, describe the difference in slope and y-intercept.
Answer:
The difference in slopes of [tex]f(x)\ and\ g(x)[/tex] is = 3
We can say slope of [tex]f(x)[/tex] is positive and 3 more than slope of [tex]g(x)[/tex] while slope of [tex]g(x)[/tex] is negative.
Difference of y-intercepts of [tex]f(x)\ and\ g(x)[/tex] is = -7
We can say the y-intercept of [tex]g(x)[/tex] is positive and 7 units above [tex]f(x)[/tex] while y-intercept of [tex]f(x)[/tex] is negative.
Step-by-step explanation:
Given equation:
[tex]f(x) =2x - 2[/tex]
[tex]g(x) =5-x[/tex]
We need to find the difference of slopes and y-intercepts of the given equations.
The standard form of a slope intercept equation of line is given by:
[tex]y=mx+b[/tex]
where [tex]m[/tex] represents slope and [tex]b[/tex] represents y-intercept of line.
Writing the given equations in standard form to find slope and y-intercept.
[tex]f(x) =2x +(-2)[/tex]
Slope = 2 and y-intercept =-2
[tex]g(x) =(-1)x+5[/tex]
Slope = -1 and y-intercept =5
The difference in slopes of [tex]f(x)\ and\ g(x)[/tex] is = [tex]2-(-1)=2+1=3[/tex]
We can say slope of [tex]f(x)[/tex] is positive and 3 more than slope of [tex]g(x)[/tex] while slope of [tex]g(x)[/tex] is negative.
Difference of y-intercepts of [tex]f(x)\ and\ g(x)[/tex] is = [tex]-2-5=-7[/tex]
We can say the y-intercept of [tex]g(x)[/tex] is positive and 7 units above [tex]f(x)[/tex] while y-intercept of [tex]f(x)[/tex] is negative.
Collette and Jakara went shopping at a local music store. The shop advertised that all CDs marked with a red dot,r, were one price and all CDs marked with a green dot,g, were another price. Collette bought 2 green-dot CDs and 4 red-dot CDs for $52. Jakara bought 3 red-dot CDs and 1 green-dot CD for $34. Write and solve a system of equations to determine how much the store charges for each green-dot and each red-dot CD.
The store charges $8 for one red dot CD and $10 for one green dot CD.
Step-by-step explanation:
Given,
Red dot CDs = r
Green dot CDs = g
According to given statement;
4r+2g=52 Eqn 1
3r+g=34 Eqn 2
Multiplying Eqn 2 by 2;
[tex]2(3r+g=34)\\6r+2g=68\ \ \ Eqn\ 3\\[/tex]
Subtracting Eqn 1 from Eqn 3
[tex](6r+2g)-(4r+2g)=68-52\\6r+2g-4r-2g=16\\2r=16[/tex]
Dividing both sides by 2;
[tex]\frac{2r}{2}=\frac{16}{2}\\r=8[/tex]
Putting r=8 in Eqn 2
[tex]3(8)+g=34\\24+g=34\\g=34-24\\g=10[/tex]
The store charges $8 for one red dot CD and $10 for one green dot CD.

By setting up and solving a system of linear equations based on the information that Collette bought 2 green-dot and 4 red-dot CDs for $52, and Jakara bought 3 red-dot CDs and 1 green-dot CD for $34, we determined that the price of each green-dot CD is $10 and each red-dot CD is $8.
Collette and Jakara went shopping at a local music store which had CDs marked with a red dot, r, at one price and CDs marked with a green dot, g, at another price. Collette bought 2 green-dot CDs and 4 red-dot CDs for $52, and Jakara bought 3 red-dot CDs and 1 green-dot CD for $34. To determine the prices for each type of CD, we set up a system of equations based on the information provided:
2g + 4r = 52 (Equation 1: Collette's purchase)
1g + 3r = 34 (Equation 2: Jakara's purchase)
We can solve this system of equations using either the substitution or the elimination method. In this answer, we will use the elimination method.
Multiply Equation 2 by 2 to align the coefficients of g: 2g + 6r = 68
Subtract Equation 1 from the new version of Equation 2 to eliminate g: (2g + 6r) - (2g + 4r) = 68 - 52
This simplifies to 2r = 16, so divide by 2 to find r: r = 8
Use the value of r to solve for g in Equation 1: 2g + 4(8) = 52
This simplifies to 2g + 32 = 52, so subtract 32 from each side: 2g = 20
Finally, divide by 2 to find g: g = 10
Therefore, the price of a green-dot CD is $10 and the price of a red-dot CD is $8.

How to solve : 16=2t + 0.25 t``squar
Answer:
The solutions of the equation are t = 4(√5 + 1) or 4(√5 - 1).
Step-by-step explanation:
We have to solve the given quadratic equation of single variable t.
The equation is 16 = 2t + 0.25t²
⇒ 0.25t² + 2t - 16 = 0
⇒ 25t² + 200t - 1600 = 0 {Multiplying both sides with 100}
⇒ 25t² + 200t + 400 - 400 - 1600 = 0
⇒ (5t + 20)² - 2000 = 0
⇒ (5t + 20)² - (20√5)² = 0
⇒ (5t + 20 + 20√5)(5t + 20 - 20√5) = 0
So, (5t + 20 + 20√5) = 0 or, (5t + 20 - 20√5) = 0
⇒ (t + 4 + 4√5) = 0 or, (t + 4 - 4√5) = 0
⇒ t = - 4(1 + √5) or, t = 4(√5 - 1) (Answer)

A fireworks rocket is launched from a hill above a lake. The rocket will fall into the lake after exploding at its maximum height. The rocket's height above the surface of the lake is given by g(x)= -16x^2+64+80. What is the maximum height of the rocket?
A) 150 feet C) 120 feet
B) 80 feet D) 144 feet
Answer:
D
Step-by-step explanation:
At the maximum height, the value of the vertical velocity Vy equals zero. From the value of the equation, we can get the vertical velocity by its first differential.
Differentiating this, we get -32x + 64
We then equate this value to zero. This yield 32x = 64 and x = 2
We now plug the value of x back into the original expression for height.
-16(2)^2 + 64(2) + 80 = -64 + 128 + 80 = 144 feet
Find the perimeter of a square with side a. Are the perimeter of the square and the length of its side directly proportional quantities? a=7.2 cm
The perimeter of a square with side a = 7.2 cm is 28.8 cm. Yes there exists a direct proportional relationship between Side length and Perimeter of square
Solution:Given that side of square "a" = 7.2 cm
We have to find the perimeter of square
The perimeter of square is given as:
Perimeter of square = 4a
Where "a" represents the length of side of square
Substituting the given value a = 7.2 cm in above formula, we get perimeter of square
Perimeter of square = 4(7.2) = 28.8 cm
Are the perimeter of the square and the length of its side directly proportional quantities?
[tex]\begin{array}{l}{\text { perimeter of square }=4 a=4 \times \text { length of side }} \\\\ {\frac{\text { perimeter of square }}{\text { length of side }}=4}\end{array}[/tex]
The Perimeter is equal to a constant times the Side length, or the Perimeter divided by the Side length is equal to four. So this is definitely a proportional relationship between Side length and Perimeter.
Two values are said to be in direct proportion when an increase in one results in an increase in the other.
So when length of sides increases, perimeter also increases
Hence perimeter and length of side of square are directly propotional quantities
Square and square root
The area of a square field is 31684m. Find the length of each side.
Answer:
178 m
Step-by-step explanation:
The area of a square is the square of one of its sides, so the square root of the area is the length of one of its sides.
√31684 = 178
Since you know the area of a square is lengh times width,
you can do…
length x width= 31684
but since you know that length=width
it is just length squared=31684
so,
length= square root of 31684
at the end length of each side of a square are the the same so, if you know one then you know all of the others,
so,
length of each side in this square is=178 meters

Answer:
x = 85
Step-by-step explanation:
There are two triangles. For the purpose of communication, I label them as right triangle and acute triangle.
All triangles' interior angles must add to 180°.
Since we already have two of the three angles in the acute triangle, we can find the third angle, which I label as "y":
180° = 25° + 60° + y
180° = 85° + y
180° - 85° = 85° - 85° + y
y = 95°
Supplementary angles are angles that add to 180°. This is true of any straight lines.
In this question, the angles x and y are supplementary because they make up a straight line.
x + y = 180°
x + 95° = 180°
x = 85°
Without all these steps, we can also figure out that x = 85 by adding 60° and 25° because the sum of a triangles' two interior angles are equivalent to the supplementary of the third angle.

The sailboat has 1 large sail and one small sail. The large sail is 24 feet tall. The base of the sail is 12 feet long. What is the area of the large sail?
The area of the large sail is 144 square feet.
Explanation:To find the area of the large sail, we can use the formula for the area of a triangle which is Area = 1/2 * base * height.
In this case, the base of the sail is 12 feet and the height (or the length of the sail) is 24 feet. Plugging these values into the formula, we get:
Area = 1/2 * 12 feet * 24 feet = 144 square feet
Therefore, the area of the large sail is 144 square feet.

The coordinates (12,6), (12,15), (4,0) represent the locations of his stops respectfully on a city map. If each unit on the coordinate plane represents 0.75 miles, how far did tony ride on the city bus?
Answer:
27 miles.
Step-by-step explanation:
The distance between two points ([tex]x_{1},y_{1}[/tex]) and ([tex]x_{2},y_{2}[/tex]) on the coordinate plane are given by the formula
[tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} }[/tex]
Therefore, the distance between points (12,6) and (12,15) is [tex]\sqrt{(12 - 12)^{2} + (15 - 6)^{2}} = 9[/tex] units
Again, the distance between the points (12,15) and (4,0) is [tex]\sqrt{(4 - 12)^{2} + (0 - 15)^{2}} = 17[/tex] units
And the dictance between the points (4,0) and (12,6) is [tex]\sqrt{(12 - 4)^{2} + (6 - 0)^{2}} = 10[/tex] units
Therefore, the total distance is (9 + 17 + 10) = 36 units.
If each unit on the coordinate plane represents 0.75 miles, then Tony rides on the city bus by (36 × 0.75) =27 miles. (Answer)

The average weight of a watermelon is 4.61 kg. The average weight of a coconut is 2.22 kg less than a watermelon. The total weight of an equal number of coconuts and watermelons is 140 kg. How many coconuts are there?
Since the average weight of a coconut is 2.22 kg less than a watermelon, its average weight is
[tex]4.61-2.22=2.39[/tex]Let n be the number of coconuts and watermelons. The total weight of n coconuts and n watermelons is
[tex]4.61n+2.39n = 7n[/tex]
If we want this total to be 140, we have
[tex]7n=140 \iff n=\dfrac{140}{7}=20[/tex]
So, you have 20 coconuts and 20 watermelons.
Final answer:
To find the number of coconuts, we can set up an equation using the given information. The average weight of a watermelon is 4.61 kg, and the average weight of a coconut is 2.22 kg less than a watermelon. By setting up the equation x(4.61 + 2.39) = 140 and solving for x, we find that there are 20 coconuts.
Explanation:
To solve this problem, we need to set up equations using the given information. Let's represent the number of coconuts as 'x'. The average weight of a watermelon is 4.61 kg, and the average weight of a coconut is 2.22 kg less than a watermelon, which means it is 4.61 - 2.22 = 2.39 kg. Since the number of coconuts and watermelons is equal, we can write the equation: x(4.61 + 2.39) = 140. Solving this equation, we get 7x = 140, which means x = 140/7 = 20.
Therefore, there are 20 coconuts.
