Answer:
We start with 0 + 40.
1. 0 + 40
2. 1 + 39
3. 2 + 38
4. 3 + 37
.....
keep going....
.....
19. 18 + 22
20. 19 + 21
21. 20 + 20
There are 21 pairs of whole numbers that have a sum of 40.
Step-by-step explanation:
hope this helps :)
Find the gradient
m = y2-y1 / x2-x1
m = 4-(-2) / 3-(-3)
m = 6 / 6
m = 1
Insert the values of one of the points into y=mx+c to find c (choosing point (3,4)):
y = mx + c
4 = 1(3) + c
c = 4 - 3
c = 1
Therefore, the equation is:
y = x + 1
Answer:
parallel
Step-by-step explanation:
The "work" is to recognize that both equations describe horizontal lines. All horizontal lines on the Cartesian coordinate grid are parallel.
_____
<em>Additional comment</em>
y = constant . . . . . a horizontal line (y=0 is the x-axis)
x = constant . . . . . a vertical line (x=0 is the y-axis)

If you wanted to go to the trouble, you could compare the equation ...
y = constant
to the slope-intercept form ...
y = mx +b
Your comparison would note that m=0. That is, the slope is zero, so the line is horizontal. All lines with the same (zero) slope are parallel.
Answer:
Step-by-step explanation:
A) = (35,?)
B) = POSITIVE
C) = 601
- (- 4) + 8 is the same as doing - 1(- 4) + 8 or - 1 x (- 4) + 8
Any negative times a negative becomes a positive so we just do 1 x 4 = 4.
4 + 8 = 12.
Your answer is 12.
