Answer:
32x - 96
Step-by-step explanation:
Apply the distributed property:
- 8 × 4x = 32x
- 8 × 12 = 96
- Re-write the expression: 32x - 96
I hope this helps!
To determine the total class the whole class spent, you just have to simply add the individual costs of the three books. Using parenthesis, the solution can be written in the following two ways:
($15 + $9) + $12 = $36
$15 + ($9 + $12) = $36
No matter where you put the parenthesis, the final answer doesn't change. This is because of the Commutative Property of Addition. The order does not matter.
Answer:
well, we do not have the options here, but we can find the equation of the graph, so the equations that are different from that are the answer to this question:
in the graph, we can see that it goes through the points:
(0,1) and (2,0)
Remember that the slope of a line that goes through the points (x1, y1) and (x2, y2) is:
s = (y2 - y1)/(x2- x1)
then the slope for our line is:
s = (0 - 1)/(2 -0) = -1/2
Then our line is:
y = -(1/2)*x + b.
b is the y-intercept, and we know that when x = 0 y = 1, then:
1 = -(1/2)*0 + b
1 = b
then the equation is:
y = -(1/2)*x + 1
161/4=40.25 so none of those choices match
