B.
2/0.8 is 2.5
I would download an app called Socratic is helps a lot!
Answer:
C
Step-by-step explanation:
Factor: -7x^2 -5x+18
Factor -1 out of 7x^2 -5x +18:
−(7x^2+5x−18)
Factor.
1. 18 is negative, so a negative number multiplied by a postive number.
2. You can't factor 7, so 7x times x.
(7x−9)(x+2)
Answer:
<u>Not true</u>: B. The radicand has been multiplied by -1.
Step-by-step explanation:
The parent function of √x has been vertically reflected and translated, but has not been horizontally reflected. Hence the sign of x is positive, not multiplied by -1.
_____
In the attached graph, the parent function (A. y=√x) is shown in purple. The function with the radicand made negative is shown in red (as a dashed line). Clearly this does not match the graph provided with your problem.
The function shown in green has the transformations described by answers C and D.
Midpoint = ((x1+x2)/2 , (y1+y2)/2) = (2+14)/2), (1+(-8)/2) = (8,-3.5)
