Here are 5 lines on a coordinate grid: Write equations for lines a,b,c,d and e a: b: c: d: e:
Answers
The equations of each of the given lines are:
Line a is: x = -4
Line b is: x = 4
Line c is: y = 4
Line d is: y = -2
Line e is: y = -¾x + 1
How to Write the Equation of a Line?If we determine the slope value, m, and the y-intercept value, b, the equation of a line can be written as y = mx + b in slope-intercept form by plugging in the values of the determined variables.
For a vertical line, the equation is expressed as x = b, where b is the x-intercept of the line.
For a horizontal line, the equation would be y = b, where b is the line's y-intercept value.
Equation of line a (vertical line):
The x-intercept is -4. This means that, the equation of line a is: x = -4
Equation of line b (vertical line):
The line's x-intercept is 4. To write the equation of the line, substitute the value of the x-intercept into x = b.
Therefore, the equation of line b is: x = 4
Equation of line c (horizontal line):
The y-intercept (b) = 4. Substitute the b = 4 into y = b.
The equation of line c is: y = 4
Equation of line d (horizontal line):
y-intercept (b) = -2. Substitute b = -2 into y = b.
Equation of line d is: y = -2
Equation of line e:
Slope (m) = rise/run = -3/4
y-intercept (b) = 1
To write the equation of the line, substitute m = -¾, and b = 1 in the equation y = mx + b
y = -¾x + 1

What is Area of Rectangle?The area of Rectangle is length times of width.
In the given figure there we can see three rectangles.
Let us divide each length to three parts.
The length 27m is divided into 3 we get
27/3=9m.
Hence each rectangle has 9m of length.
The width 30m is divided into 3 parts we get,
30/3=10m.
Hence area of each rectangle is 9×10=90 sq. m

Answer:
x = 10°
Step-by-step explanation:
Given the figure with angles 2x, 4x, 5x, and 50° marked, you want to find the value of x.
Development∠HAC = ∠HCA . . . . base angles of isosceles triangle HAC
2(∠HAC) = 4x . . . . . exterior angle 4x is equal to the sum of the equal remote interior angles HAC and HCA
∠HAC = 2x . . . . . . . divide by 2
∠AED = 180° -2x -2x = 180° -4x . . . . sum of angles in ∆AED is 180°
∠AHC = 180° -4x . . . . angles at H are a linear pair
HC ║ ED . . . . converse of corresponding angles theorem
∠FEG = ∠FCH = 50° . . . . . corresponding angles theorem

In this question, we have been given a rectangle TUVW with vertices
T(-3,-1), U(0, -2), V(-2, -8) and W(-5, -7)
We know that for 90° counterclockwise rotation is (x, y) becomes (-y, x)
so, the coordinates of T' would be,
T' = (1, -3)
the coordinates of U' would be,
U' = (2, 0)
the coordinates of V' would be,
V' = (8, -2)
the coordinates of W' would be,

The equivalent expression for the indices is 17⁻⁷ × 17⁵ is 1/17²
How to create an equivalent expression for 17⁻⁷ × 17⁵?Index is the power or exponent which is raised to a number or a variable e.g in number 3⁵, 5 is the index of 3. The 3 is called the base. The plural form of index is indices.
We have different Laws of Indices, but the one applicable to this question is the product law and reciprocal law.
Product law: To multiply two variables or numbers with the same base, we need to add their powers and raise them to that base": 5² x 5³ = 5²⁺³ = 5 and P⁴ + P⁶ = P¹⁰
Reciprocal Law: If the index is a negative value, then it can be shown as the reciprocal of the positive index raised to the same variable:
8⁻² = 1/8² and b⁻⁶ = 1/b⁶
Let's use the two laws to create an equivalent expression for 17⁻⁷ × 17⁵:
17⁻⁷ × 17⁵ = 17⁻⁷ ⁺ ⁵ = 17⁻² = 1/17²
Therefore, the equivalent expression for 17⁻⁷ × 17⁵ is 1/17². The 1st option is the answer.

the admission fee at an amusement park is $2.00 for children and $7.00 for adults. on a certain day, 299 people entered the park, and the admission fees collected totaled $1573. how many children and how many adults were admitted?
Answers
Answer:
104 children and 195 adults
Step-by-step explanation:
let a represent number of adults and c represent number of children , then
a + c = 299 → (1)
7a + 2c = 1573 → (2)
multiplying (1) by - 2 and adding to (2) will eliminate c
- 2a - 2c = - 598 → (3)
add (2) and (3) term by term to eliminate c
5a + 0 = 975
5a = 975 ( divide both sides by 5 )
a = 195
substitute a = 195 into (1) and solve for c
195 + c = 299 ( subtract 195 from both sides )
c = 104
104 children and 195 adults were admitted

Answers
This company’s revenue function is given by −0.25x³ - 4x² + 1000x + 16,000.
How to determine company's revenue function?Mathematically, the amount of revenue that's being generated by a company or business organization can be calculated by using the following function (expression):
Revenue = price × demand
R(x) = p(x) × d(x)
The demand (d) for this company’s product at cost (x) is given by this demand function:
d(x) = −0.25x² + 1,000
Also, the price (p) in dollars that this company can charge for its product is given by this price function:
p(x) = x + 16
Substituting the parameters into the revenue function, we have;
Revenue function, R(x) = p(x) × d(x)
Revenue function, R(x) = (−0.25x² + 1,000) × (x + 16)
Revenue function, R(x) = −0.25x³ - 4x² + 1000x + 16,000.

Answers
The base of the garden is 14.4 feet.
The height of the garden is 6 feet.
Given,
Corey is designing a rectangular garden;
The diagonal of the garden = 15.6 feet
Ratio between garden's base and height = 12:5
We have to find the length of base and height of the garden.
Here,
Diagonal of a rectangle, d = [tex]\sqrt{base^{2}+ height^{2} }[/tex]
Base = 12x
Height = 5x
Then,
Diagonal, 15.6 = [tex]\sqrt{(12x)^{2} + (5x)^{2} }[/tex]
15.6 = [tex]\sqrt{144x^{2} +25x^{2} }[/tex]
15.6 = √169x²
15.6 = 13 √x²
15.6 = 13x
x = 15.6/13
x = 1.2
Then,
Base of the garden = 12 x 1.2 = 14.4 feet
Height of the garden = 5 x 1.2 = 6 feet

The difference of 0.27 is not statistically significant.
A statistically significant difference indicates if the responses of one group differ significantly from those of another when using statistical testing.
The statistically significant differences between the numbers really aid in your data analysis. It is up to you how to interpret or act on your results, therefore you should also think about if they are significant.Let's imagine, for instance, that you get more consumer complaints from women than from men. How do you know that this is a genuine issue that has to be addressed? To find out if your male consumers are significantly more satisfied with your goods, doing a poll is a terrific technique. Our statistical significance tool can assist you in determining whether males are considerably more satisfied with your goods than women using a statistical formula. This enables you to base decisions on facts rather than anecdotes.Now we know that any data of t-statistic that is greater than 1.96 is statistically significant.
Now the difference is 0.27. Hence it is not statistically significant.

Answers
JK is perpendicular to a line that has a slope
What is Slope?
The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same).
Two lines, L1 and L2, with slopes m1 and m2 are perpendicular if
m1 x m2 = -1.
In our case m1 = 1
1 x m2 = -1
m2 = -2
so the slope of the perpendicular line is -2.
( -2 x (1) = -1).
As x increases, the line with a slope of -2 increases. Line JK is the only line displayed that fits this. Line AB cannot be the solution because it is "falling" as x grows.

Step 1 of 2: Determine the missing coordinate in the ordered pair (4, ?) so that it will satisfy the given equation.
Answers
Answer:
Substitute x = 4 into the equation to find y.
2(4) + y = 2
8 + y = 2
y = -6
To check if it satisfies the equation, substitute values of x and y into the equation.
2(4) + (-6) = 2
8 - 6 = 2
Since, it satisfies the equation, the missing coordinate is -6.
2(4)+y=2
now multiply 2 by 4 to remove parentheses
8+y=2
subtract by 8 on both sides
y=-6
if you want to check if this is correct, simply change y to -6
2(4)+(-6)=2
8+(-6)=2
