(A) <em>The rate that the point 8,28 represents is;</em> 3.5 cm/s since 28/8 = 3.5
(B) <em>The unit rate is 3.5 cm/s since the rate is constant.</em>
(C) <em>The points lie on the same line and both points results to a rate of 3.5 cm/s.</em>
Combine like terms by subtracting x from both sides.
x + 4 = 2x
4 = 2x - x
4 = x
(On one side, x-x cancelled out, and on the other side, the 2x-x works like normal subtraction so you are left with x. Therefore x is 4)
9x2= 18
24x2= 48
48-18= 30
30 is the difference.
Since it is 9x2-24x2 it would be 18-48
So the answer would be -30.
48:12
because 60-12 is 48 and 48 plants sprouted and 12 did not
Answer:
(-2.5, 0.5)
Step-by-step explanation:
(-4) + (-1) / 2 = -2.5
5 + (-4) / 2 = 0.5
