Hey there!
1, 8.95*.4= 3.58 was take off. 8.95-3.58= 5.37
$5.37
2.<span>A change from 85 to 72 represents a negative change (decrease) of -15.294117647058824%</span>
y=2x+4
that is an equation in slope intercept form where the slope is 2 so you would go up two right 1 and the y intercept would be 4 so (0,4)
48000 ounces is the weight of the hippo
The total cost for a $1,200 washing machine is $1,200. In the real world it would be 1,200 + tax.
(x+b/2a)^2-(b^2-4ac)/2a=0
Step 2:
Re-write the expression:
(x+b/2a)^2=(b^2-4ac)/4a^2
Step 3:
get the square root of both sides:
x+b/2a=sqrt[(b^2-4ac)/4a^2]
Step 4:
Simplifying we get:
x+b/2a=sqrt[b^2-4ac]/2a
Step 5
Make x the subject:
x=-b/2a+/-sqrt[b^2-4ac]/2a
