Answer:
Step-by-step explanation:
the first graph has points (-1, -1) and (2, -2)
slope m = (y2-y1) / (x2-x1) = (-1+2)/ (-1-2) = 1/-3 = -1/3
the second graph has points (0, -3) and (2, 0)
slope m = (y2-y1) / (x2-x1) = (-3-0)/ (0-2) = -3/-2 = 3/2
for the table
x. y
-3. 4
0. 1
slope m = dierence in y /diference in x = 4-1 / -3-0 = 3/-3= -1
Answer:
1. Communitave property
2. communitave property
3.
1. distribute 2 to x and 10 to get ride of parenthesis
2. subtract 2x from the left to move it to the right so x is by itself
3. add 15 to both sides to cancel it out on one side, and move to the other.
4. divide by 5 on both sides so you can get the value of x
5. flip equation so it is in the x equals form
4.
1. distribute 2 to the x and positive 3 on the left side, also distribute -4 to both x and -1 , to get rid of our parenthesis.
2. add 4x to both sides so it cancels out on one side and moves to the other ( our xs and numbers need to be on opposite sides)
3. subtract 4 on the left side to move it to the right side because again numbers on the right and letters on the left
4. divide by 6 on both sides of the equation to solve for x
Since there is no equation for this, just plug in numbers and find the numbers that work. After plugging in a couple of numbers, I found that 16*2-10=22, and 16+22=38. Therefor, the answers are 16 and 38.
Answer:
x=4
Step-by-step explanation:
the triangles are directly porportional.
if 2.5 is half of 5, to find x is just half of 8.
0.836, 0.683, 0.386, and then 0.3
