Which equation represents a line which is parallel to the line 7y−x=−28?
The equation represents a line which is parallel to the line 7y−x=−28 is y=1/7 x.
The given equation is 7y-x=-28.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Here, equation can be rewritten as x-7y-28=0
So, slope of line = 1
As we know, slope of parallel lines are equal. If the slopes of two parallel lines are represented as m1, m2 then we have m1 = m2.
Now, m1 = m2 = 1
Find the slope of the original line and use the point-slope formula y−y1=m(x−x1) to find the line parallel to 7y−x=−28.
y=1/7 x
Therefore, the equation represents a line which is parallel to the line 7y−x=−28 is y=1/7 x.

What is arithmetic Progression?The difference between every two subsequent words in a sequence is the same; this is known as an arithmetic progression (AP). An equation for the previous block of the AP may be derived from this kind of development. For instance, the sequence 2, 6, 10, 14,... is a mathematical progression (AP) because it fits a pattern where every other number is acquired by adding 4 to the respective period.
The given data is,
-10, 20, -40
From -10 to 20 it is multiplied by 2 with a positive sign, and from 20 to -40 it is multiplied by 2 with a negative sign. Similarly, the next two numbers are 80 and -160.

Find the perimeter and area of the figure if each unit on the graph measures 1 centimeter. Round answers to the nearest tenth, if necessary.
The perimeter and area of the rectangle shown are 22 centimeters and 30 centimeters square respectively.
How to determine the valueFrom the diagram shown, we have that the each point measures 1 centimeter
The length of the rectangle measures 5 pints which is 5 centimeters
The width of the rectangle measures 6 points which is 6 centimeters.
The formula for perimeter of a rectangle is expressed as;
Perimeter = 2 ( length + width)
substitute the values into the equation
Perimeter = 2 ( 5 + 6)
Perimeter = 2(11)
Perimeter = 22 centimeters
Area = length × width
Area = 6 × 5
Area = 30 centimeters square
Thus, the perimeter and area of the rectangle shown are 22 centimeters and 30 centimeters square respectively.

We are told that Junior's tax =
Junior takes two pieces for himself for every five pieces the student buys.
If his friend George bought 35 pieces of candy, how many pieces will go to Junior?
The tax is represented as :
Junior : George
2 : 5
Hence:
2/5 = x/35
Cross Multiply
5x = 2 × 35
x = 70/5
x = 14
Hence, if George buys 35 pieces of candy, 14 pieces of candy goes to Junior

Which are lines that will intersect?
✔ a and b
Which are perpendicular lines?
✔ b and d
Which are skew lines?
✔ a and c
Lines a and b will intersect, lines b and line d are perpendicular and lines a and c are skew.
Two lines intersect, when both lines cross each other's paths i.e. they have a point of intersection.
Perpendicular lines are simply lines intersecting at a right-angle
Skew lines are two lines that are in different planes, that are neither parallel, nor intersecting.
From the diagram, we can see that-
When lines a and b are extended downwards, they will intersect at some point, thus a and b are intersecting.
Line b and the horizontal line between both planes, intersect at a right-angle. Thus, b and d are perpendicular.
Lines a and c are in different planes (i.e. they are non-coplanar)
Lines a and c do not intersect.
Hence, lines a and c are skew.

Step-by-step explanation:
Generally, the equation of a quadratic formula can be written as;
y = ax^2 + bc + c
From the graph, we have three points and we want to form equations from these points
These points are;
(-1,5) (0,-4) and (4,0)
To get the equation from each point, we make a substitution for both x and y
For the first;
5 = a(-1)^2 + b(-1) + c
5 = a-b + c
For the second;
-4 = a(0)^2 + b(0) + c
c = -4
For the third;
0 = a(4)^2 + b(4) + c
0 = 16a + 4b + c

The value of x from the given linear function is -48
What are linear equations?Linear equations are equation that has a leading degree of 1. For instance the equation y = mx + b is a linear equation.
Given the equation below
-x/3 + 4 =20
We are to determine the value of x
Subtract 4 from both sides to have;
-x/3 + 4 - 4 = 20 - 4
-x/3 =20 - 4
-x/3 = 16
Multiply both sides by 3 to have
-x = 3(16)
-x = 48
x = -48
Hence the value of x from the given linear function is -48

factor of 1/3.
To draw a scaled copy of the polygon using a scale factor of 1/3, just multiply the given sides of the polygon with 1/3 and the outcome is the new polygon with a scale factor of 1/3.
What is a scale factor?You shall specify the extent of the shape's enlargement when describing one. The scaling factor refers to this. A scale factor of 2, for instance, indicates that the new shape is twice as large as the previous shape.
The size of the shape reduces when the scaling factor is a fraction, yet we still refer to this as an enlargement. A scale factor of 1/4 therefore indicates that the new shape is 1/4 as large as the old one.
Make sure you never confuse the scale factor. One might mistake a scale factor of 2 for a scale factor of 12, or a scale factor of 4 for a scale factor of 14.
