= 1/8 x
Step-by-step explanation:
Answer: (6, -30)
Step-by-step explanation:
Substitute the points into the equation:
3.5 = -1/2(1^3) - 3(1) + 7 = 3.5: (1, 3.5) is on the graph.
-60.5 = -1/2 (9^2) -3(9) + 7 = -60.5: (9, -60.5) is on the graph.
-1 = -1/2 (-8^2) -3(-8) + 7 = -1. (-8, -1) is on the graph.
-30 = -1/2(6^2) -3(6) + 7 = -29 (6, -30) is not on the graoh.
Answer:
1. 3/10 is equal to .3 or 30%
2. 7/10 is equal to .7 or 70%
3. The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = (30 +20) you can distribute the value outside of the parentheses to the values inside.
I don't know if I am right but I think this is the answer:
If we write beaker with x and content with y
then y=56.8/2=28.4 this is the content of one beaker
so there are two beakers:
2x+28.4=180.4
2x=180.4-28.4
2x=152/2
x=76
