Answer:
D.
Step-by-step explanation:
-2/5 - (-9/15) = -2/5 + 9/15.
both of those equations are equivalent.
hope this helps.
You have to be a bit more specific than that

e
Step-by-step explanation:
<h2>Percent of speed the machine increase is 20%</h2>
<h2>Given that;`</h2>
Number of ice cream produced before = 45
Number of ice cream produced after = 54
<h2>Find:</h2>
Percent of speed the machine increase
<h2>Computation:</h2>
Percent of speed the machine increase = [Number of ice cream produced after - Number of ice cream produced before] / Number of ice cream produced before
Percent of speed the machine increase = [(54 - 45) / 45]100
Percent of speed the machine increase = [9 / 45]100
Percent of speed the machine increase = 20%

Answer:
Option (4)
Step-by-step explanation:
Vertices of the triangle are X(0, -4), Y(2, -3) and Z(2, -6).
Slope of XY (
) = 
= 
(
) = 
Similarly, slope of XZ (
) =
(
) = (-1)
Which should be (-1) if XY and XZ are perpendicular to each other.
Now we can say that XY and XZ are not perpendicular.
Therefore, Lydia's assertion that ΔXYZ is a right triangle is not correct.
Option (4) will be the answer.
