Question:
A system of equations is given below. [tex]y = -2x + \frac{1}{4}[/tex] and [tex]y = -2x - \frac{1}{4}[/tex].
What is true about both lines?
Answer:
They have the same slope but different y-intercepts, so they have no solution.
Step-by-step explanation:
Given
[tex]y = -2x + \frac{1}{4}[/tex]
[tex]y = -2x - \frac{1}{4}[/tex]
Required
Which is true?
A linear equation is represented as:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
[tex]b = y\ intercept[/tex]
For: [tex]y = -2x + \frac{1}{4}[/tex]
[tex]m = -2[/tex]
[tex]b = \frac{1}{4}[/tex]
For [tex]y = -2x - \frac{1}{4}[/tex]
[tex]m = -2[/tex]
[tex]b = -\frac{1}{4}[/tex]
This implies that both equations have the same slope but different y intercept.
When two equations have the same slope but different y intercept; such system of equation has no solution.

The endpoints of a line segment are (4,6) and (-6,2). Point G divides the segment into two equal parts. What are the coordinates of point G? O (-8, 12) 0 (-5,2) O (-2,8) O (-1,4)
Answer:
(-1, 4)
Step-by-step explanation:
Given the endpoints of line segments to be (4,6) and (-6,2).
Coordinate of point G is expressed as its midpoint;
M(X, Y) = {x1+x2/2, y1+y2/2}
X = 4-6/2
X = -2/2
X = -1
Y = 6+2/2
Y = 8/2
Y = 4
Hence the coordinate of point G is (-1, 4)
Pizza by the Pan sold 4 dozen pizzas in the afternoon. That night, they sold 2.5 times as many pizzas as they did during the afternoon. How many pizzas did they sell in all that day?
Answer:
they sold 14 pizzas all day.
Step-by-step explanation:
4 x 2 = 8
0.5 means half of what they sold in the afternoon
4 ÷ 2 = 2
now add them both together to get the number of pizzas they sold at night.
8 + 2 = 10
now add the afternoon and night together
10 + 4 = 14
answer: 14 pizzas

A rectangular pyramid. The rectangular base has a length of 10 inches and a width of 6 inches. 2 triangular sides have a base of 10 inches and height of 5.6 inches. 2 triangular sides have a base of 5 inches and height of 7.1 inches.
Answer:
Answer:
a) The base of the rectangular pyramid shown has an area of
60 square inches
b) A triangular face with a base of 10 inches has an area of 28 square inches.
c) A triangular face with a base of 5 inches has an area of 17.75 square inches.
d) The total surface area of the pyramid is 151.5 square inches.
Step-by-step explanation:
a) Solving for question a, we were given the following parameters
A rectangular pyramid. The rectangular base has a length of 10 inches and a width of 6 inches
The formula used to calculate the rectangular base of a rectangular pyramid =
Length × Width
Where :
Length = 10 inches
Width = 6 inches
Rectangular base = 10 inches × 6 inches
= 60 inches²
Hence, the base of the rectangular pyramid shown has an area of 60 square inches
b) Solving for question b, we have the following values given:
2 triangular sides have a base of 10 inches and height of 5.6 inches.
First step would be to solve for one triangular side first.
The area of the one triangular side = (Base × Height) ÷ 2
= (10 inches × 5.6 inches) ÷ 2
= 56inches² ÷ 2
= 28 inches²
Therefore, for the 2 triangular sides, since they have the same base and height, the other side as well would be 28 inches².
A triangular face with a base of 10 inches has an area of 28 square inches.
c) Solving for question c, the following parameters are given:
2 triangular sides have a base of 5 inches and height of 7.1 inches.
We would be to solving for one triangular side first.
The area of the one triangular side = (Base × Height) ÷ 2
= (5 inches × 7.1 inches) ÷ 2
= 35.5 inches² ÷ 2
= 17.75 inches²
Therefore, for the 2 triangular sides, since they have the same base and height, the other side as well would be 17.75 inches².
A triangular face with a base of 5 inches has an area of 17.75 square inches.
d) Solving for d, it is important to note that, a rectangular pyramid has 5 faces and they are: The rectangular base and 4 triangular faces
The formula for the total surface area of the rectangular pyramid is given as
Total Surface Area of the rectangular pyramid = Rectangular Base + Area of Triangular Side A + Area of Triangular Side B + Area of Triangular Side C + Area of Triangular Side D + Area of Triangular Side E
Total Surface Area of the Rectangular Pyramid = 60 inches² + 28 inches² + 28 inches² + 17.75 inches² + 17.75 inches²
Total surface Area of the Rectangular pyramid = 151.5 inches²
The total surface area of the pyramid is 151.5 square inches.

An airplane flies 56 miles due north and then 33 miles due east. How many miles is the
plane from its starting point?
Answer:
65 miles
Step-by-step explanation:
using the Pythagorean theorem:
56²+ 33² = d²
d² = 4225
d = 65 miles
The distance of the plane from the starting point will be 65 miles. Distance or the displacement in the given case is found by the phythogorous theorem.
What is the distance?Distance is a numerical representation of the distance between two objects or locations.
The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
An airplane flies 56 miles due north and then 33 miles due east.
The distance can be found with the help of the phythogorous theorem. The following calculation is done.
[tex]\rm AB^2+BC^2=AC^2 \\\\\rm (56)^2+(33)^2=AC^2 \\\\AC=65 \ miles[/tex]
Hence the distance of the plane from the starting point will be 65 miles.
