What would the sum of -18-(-12) be?
Answers
Since there is two negative sign, it turns into positive meaning the -12 becomes positive 12 and the -18 stays same. So -18+12=-6 because 18 is bigger than 12 and it's negative so the final answer should be negative.
Hint: when you see two negative sign just turn them into plus sign.
Since (-*-)= + sign
So -18+12 will be equal to -6

By looking at the image, all we need to do is look at our given values to get the base and height. The base is the length of the bottom side of the triangle that is perpendicular to the height (the dashed line). 20 is the length on the bottem line (base) and 9.6 is the length of the dashed line (height). Meaning the base is 20 and the height is 9.6. Hope this helps.

1) The slope of the point (0,0) and (2,1) is 1/2.
2) The slope of the point (0,-1) and (2,-5) is -2.
3) The slope of the point (0,7) and (2,4) is -3/2.
4) The points (-1,3) and (-1,-3) has No slope.
5) The slope of the point (1,-3) and (-1,-3) is zero.
Step-by-step explanation:
There are five set of points given in the question.
You need to find out the slope of the line formed by the points.
The formula used to find the slope of a line is given by,
Slope =
1) The given points are (0,0) and (2,1)
(x1,y1) ⇒ (0,0)
(x2,y2) ⇒ (2,1)
Slope =
⇒ 1/2 is the slope.
2) The given points are (0,-1) and (2,-5)
(x1,y1) ⇒ (0,-1)
(x2,y2) ⇒ (2,-5)
Slope =
⇒
⇒ -2 is the slope.
3) The given points are (0,7) and (2,4)
(x1,y1) ⇒ (0,7)
(x2,y2) ⇒ (2,4)
Slope =
⇒ -3/2 is the slope.
4) The given points are (-1,3) and (-1,-3)
(x1,y1) ⇒ (-1,3)
(x2,y2) ⇒ (-1,-3)
Slope =
⇒ -6/0 (No slope)
If the denominator of a fraction is zero, the expression is not a legal fraction because it's overall value is undefined.
∴ There is no slope.
5) The given points are (1,-3) and (-1,-3)
(x1,y1) ⇒ (1,-3)
(x2,y2) ⇒ (-1,-3)
Slope =
⇒ 0/-2
∴ The slope is zero.
1) The slope of the point (0,0) and (2,1) is 1/2.
2) The slope of the point (0,-1) and (2,-5) is -2.
3) The slope of the point (0,7) and (2,4) is -3/2.
4) The points (-1,3) and (-1,-3) has No slope.
5) The slope of the point (1,-3) and (-1,-3) is zero.
The slope of a line represents the rate at which the line rises or falls as you move horizontally along it. It's calculated as the change in the y-coordinate divided by the change in the x-coordinate between two points on the line.
1. (0, 0) and (2, 1):
Slope = (1 - 0) / (2 - 0) = 1 / 2 = 0.5
The slope is positive, indicating a rising line.
2. (0, -1) and (2, -5):
Slope = (-5 - (-1)) / (2 - 0) = -4 / 2 = -2
The slope is negative, indicating a falling line.
3. (0, 7) and (2, 4):
Slope = (4 - 7) / (2 - 0) = -3 / 2
The slope is negative, indicating a falling line.
4. (-1, 3) and (-1, -3):
Slope = (-3 - 3) / (-1 - (-1)) = -6 / 0
The denominator is zero, indicating a vertical line. Vertical lines have undefined slopes.
5. (1, -3) and (-1, -3):
Slope = (-3 - (-3)) / (-1 - 1) = 0 / -2 = 0
The slope is zero, indicating a horizontal line.

the total cost of renting a bicycle for h hours?
Answers
The missing choices are:
A. C = 9h + 4
B. C = 4h + 9
C. C = 4(h - 1) + 9
D. C = 13h
C = 4(h - 1) + 9 represents this situation ⇒ answer C
Step-by-step explanation:
The given is:
- The cost of renting a bicycle is $9 for the first hour
- Another $4 for each additional hour
- C is the total cost of renting a bicycle for h hours
We need to find which of the following represents this situation
∵ The cost of renting a bicycle is $9 for the first hour
∵ Another $4 for each additional hour
∵ h represents the number of hours
- Add the cost of the first hour to the cost of the remaining hours
∵ The remaining hours = h - 1
∴ The cost of the remaining hours = 4(h - 1)
∵ C is the cost of renting the bicycle for h hour
- Add 9 to 4(h - 1) to find C
∴ C = 4(h -1) + 9
C = 4(h - 1) + 9 represents this situation

Answers
So, if one angle is 4y, the complementary angle is 90°- 4y. Choice A.
Complementary angles does not necessarily need to share a line or vertex. As long as both angles have a sum of 90°, then, they are complementary angles.
Angles who has a sum of 180° are called supplementary angles.
