If the sides to a triangle are 20, 40, and 80 cem, is it Right triangle?
Answers
Answer: no
because using Pytago theorem, we have:
20² + 40² ≠ 80²
80² + 20² ≠ 40²
80² + 40 ² ≠ 20²
Step-by-step explanation:
Answer:
No, it does not follow the Pythagorean Theorem.
Step-by-step explanation:
A right triangle must follow the equation a^2 + b^2 = c^2 for its sides to be true. 20^2 + 40^2 = 2000.
the square root of 2000 equals about 44.7213595.
Thus, a triangle with sides 20, 40, and 80 is not a right triangle.

The domain of 0 ≤ x ≤ 6 is x ∈ [0, 1, 2, 3, 4, 5, 6], and the range of the 0 ≤ y ≤ 6 is y ∈ [0, 1, 2, 3, 4, 5, 6].
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
0 ≤ y ≤ 72
The range will be y ∈ [0, 72]
0 ≤ x ≤ 72
The domain will be x ∈ [0, 72]
0 ≤ x ≤ 6
The domain will be x ∈ [0, 1, 2, 3, 4, 5, 6]
0 ≤ y ≤ 6
The range will be y ∈ [0, 1, 2, 3, 4, 5, 6]
Thus, the domain of 0 ≤ x ≤ 6 is x ∈ [0, 1, 2, 3, 4, 5, 6], and the range of the 0 ≤ y ≤ 6 is y ∈ [0, 1, 2, 3, 4, 5, 6].

Jennifer walks 9 blocks south and 5 blocks west. Approximately how many blocks is she from home if she were to take a direct path?
Answers
9514 1404 393
Answer:
10.3
Step-by-step explanation:
Assuming the blocks are square, we can use the Pythagorean theorem to find the diagonal distance.
d² = 9² +5² = 81 +25 = 106
d = √106 ≈ 10.3
Jennifer is about 10.3 blocks from home.

What is the slope of the line that passes through the points (10, 3) and (2, 3) ?
Answers
(3-3)/(2-10) = 0/-8 = 0
The slope is 0
Work Shown:
Use the slope formula
m = (y2 - y1)/(x2 - x1)
m = (3-3)/(2-10)
m = 0/(-8)
m = 0
The slope of any horizontal line is always zero due to the fact all y coordinates on this line are the same. When we pick two points from the line, the same y coordinates subtract to 0. We can have 0 in the numerator, but not in the denominator.
As the slope formula shows, we basically subtract the y coordinates together, and do the same for the x coordinates as well in the same order. Then we divide the differences.

4x – 2y = 2
x = y + 4
Answers
Answer:
y = -7 and x = -3
Step-by-step explanation:
Substitute x for y + 4 in the first equation and solve for y
4(y+4) - 2y = 2
4y + 16 - 2y = 2
16 + 2y = 2
2y = -14
y = -7
Then in order to find x, substitute y for -7 in the second equation
x = -7 + 4
x = -3
Answer:
x= -3, y= -7
Step-by-step explanation:
substitute x=y+4 in the first equation
4 (y+4) -2y =2 distribute
4y+16-2y=2 subtract both sides by 16
4y-2y=2-16 combine like terms
2y= -14 divide both sides by 2
y=-7
x=y+4 substitute y=-7
x= -7+4
x= -3
