Answer: D
<u>Step-by-step explanation:</u>
Let x represent the score on her next test


78 + 92 + 88 + 89 + x = 5(90)
347 + x = 450
<u> -347 </u> <u>-347 </u>
x = 103
We have that
the point J (10,-6)
the rule is-----------(x,y)-------------------> (x-3, y-2)
therefore
J (10,-6)----------------- > (10-3,-6-2)--------> (7,-8)
the answer is
<span>the y-coordinate of J” is -8</span>
No is your answer
Assuming that b ≠ a, the answers will not be the same.
For example, (remembering that b ≠ a) let us assume that b = 10, a = 5
10 - 5 = 5
5 - 10 = -5
5 ≠ -5
So the commutative property of subtraction does not work unless in certain cases, in which a = b.
hope this helps
we know that
the volume of a rectangular prism is equal to

where
L is the length of the box
W is the width of the box
H is is the height of the box
in this problem we have




<u>Find the length of the box</u>
Using a graph tool-------> we will determine the roots of the equation of volume
see the attached figure
the roots are

so

therefore
<u>the answer is</u>
the length of the box is equal to
