Answer:
y = -8/3x + 73/4
Step-by-step explanation:
A line perpendicular to the 3rd equation has a slope that is the negative inverse of the other line. It also has the same y-intercept (b) because it is forming a square.
Therefore, the equation of the 4th line is:
y = -8/3x + 73/4

The Triangle Similar to ΔABC is ΔDEF in which m <E = 80 and m <F = 35.
The Correct option is (A).
What is Angle Sum PropertyAccording to the triangle's "angle sum property," a triangle's interior angles add up to 180°.
What is Similarity of Triangles?If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable.
Given:
In ABC, m<A= 65 and m<B= 80
Now, using Angle sum Property
m<A + m <B + m <C = 180
65+ 80 + m<C= 180
m <C = 180 - 145
m <C = 35
So, the similar Triangle will be DEF in which m <E = 80 and m <F = 35.

The value of a=0 in a given expression.
what are expression?A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of phrases. The other number is x, and a number is 6 greater than half of it. In a mathematical expression, this proposition is denoted by the equation x/2 + 6.
Define algebraic expression.An algebraic expression in mathematics is an expression created using variables, constant algebraic numbers, and algebraic operations. A good example of an algebraic expression is 3x2 2xy + c.
If the value of 2x² - a*5 when x = 0 is 0, then we can substitute x = 0 into the equation and solve for a.

The cost of filling the cone to its full capacity would be = 189.4 cents
What is a cone?A cone is a three-dimensional figure in geometry that tapers from a flat base (usually a circular base) to a point called a vertex or longitude (which forms an axis through the center of the base).
The formula for the volume of a cone = πr²h/3
Height (h) = 5 inches
Radius (r) = 3 inches
π = 3.14
volume = 3.14 × 3² × 5/3

A Sale at Tinley’s Department Store Tinley’s department store is having a 25% off sale. Victor has a $15 Tinley’s gift certificate that he wants to use towards a sweater with an original price of $32.00. He is unsure which method the sales clerk will use to calculate the amount owed. Method #1: Subtract $15 from the price and take 25% off the resulting price. Method #2: Take 25% off the original price and then subtract $15.
Answer:
Method 1: $12.75
Method 2: $9
Step-by-step explanation:
method #1: 32-15 is $17
In order to take off a percentage, we must find that percentage of the amount. To do this, we must multiply by the percent in decimal form, so
[tex]17 \times .25 = 4.25[/tex]
Now, this amount just represents the percent of 17 we would take off, so we must take that amount off.
[tex]17 - 4.25 = 12.75[/tex]
We would pay $12.75
Method #2:
There are a few ways to do this with 25%. we know 25% is 1/4, and 1/4 or $32 is 8. so we can simply take that off from the start. Otherwise, we can follow the method above as follows
[tex]32 \times .25 = 8[/tex]
Again, this is the amount off so we must subtract.
[tex]32 - 8 = 24[/tex]
now, we subtract 15.
[tex]24 - 15 = 9[/tex]
We would pay $9 using this method.

Does a parabola have an inverse?
An inverse does not exist for a parabola.
What is a parabola?A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics.
It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves.
An inverse does not exist for a parabola.
One definition of a parabola includes a line and a point (the focus) (the directrix).
The directrix is not the main focus.
The locus of points in that plane that are equally spaced apart from the directrix and the focus is known as the parabola.
A right circular conical surface and a plane parallel to another plane that is tangential to the conical surface intersect to form a parabola, which is also known as a conic section.
Therefore, an inverse does not exist for a parabola.

Area of the cuboid box = (2*FA)+(2*SA)+(2*TA)
Where FA= Front face area
SA= Side face area
TA= top face are
Here FA= length * breadth = 10*6=60 sq meter

James is building a doll house that is proportional to his own house. He is using a scale of 0. 5inch = 1foot. If the doll house is 12. 3inches tall, how tall is his house. ?
James's house is 24.6 feet tall because he is using a scale of 0.5 inch per 1 foot. To get this measurement, he multiplied 12.3 inches (the height of the doll house) by 2.
1. Take the height of the doll house (12.3 inches).
2. Multiply 12.3 inches by 2.
3. The result is 24.6 feet which is the height of James's house.
James is building a doll house that is proportional to his own house. He is using a scale of
0.5 inch = 1 foot,
which means that for every 0.5 inch in the doll house, 1 foot is represented in his house. To calculate how tall his house is, we need to figure out how many inches the doll house is. The doll house is 12.3 inches tall. To get the height of James's house, we need to multiply this by 2. Thus, 12.3 inches multiplied by 2 equals 24.6 feet, which is the height of James's house. This is because for every 0.5 inch in the doll house, 1 foot is represented in his house. Therefore, with the scale of 0.5 inch = 1 foot, the height of James's house is 24.6 feet.
1. Determine the scale of the doll house (0.5 inch = 1 foot).
2. Measure the height of the doll house (12.3 inches).
3. Multiply 12.3 inches by 2.
4. The result is 24.6 feet which is the height of James's house.

Identify the figure that illustrates "A reflection in line k."
The 1st figure is correct, the 4th one seems very similar to the 1st one. But the red shape is closer to line k. So the 1st one is correct
The figure that illustrates a reflection in line k is figure C.
We have given that the figure.
We have to determine the correct option a reflection in line k.
A reflecting line is a perpendicular bisector.
When a figure is reflected, the reflecting line is the perpendicular bisector of all segments that connect pre-image points to their corresponding image points.
Therefore option c is correct.
Therefore, the figure that illustrates a reflection in line k is figure C.

On solving the provided proportionality question we got that, U = 7.72, is rounded off nearest to tenth digit.
What is proportionality?When two quantities or variables are linearly related in mathematics, the term "proportional" is used. Both quantities increase by two times when one increases by two. Each variable decreases in proportion to the other when it falls to 1/100th of its previous value.We must determine the ratio of the two quantities for each value supplied in order to determine if two quantities are proportionate. The proportionate link between them is evident if their proportions are equal. Their connection is not proportionate if all the ratios are out of balance.
Here,
U/5 = 17/11
U = 17/11 X 5
U = 7.72
