<u>Answer:</u>
D
of Y = (-3/2, -1)
<u>Step-by-step explanation:</u>
We are given three points on the graph:
X (4, 0)
Y (3, 2)
Z (2, 2)
and the scale factor of dilation which is 
.
Given that, we are to find the coordinates of Y after dilation. To find that, we will multiply the coordinates of the point Y with the scale factor.
Y = 
× 
, (-\frac{1}{2}[/tex] × 
Y = 
First square both sides to get:
c + 22 = (c + 2)^2
or
c + 22 = c^2 + 4c + 4
Move the terms on the left side to the right side:
c^2 + 3c - 18 = 0
Factor to get:
(c + 6) * (c - 3) = 0.
The solutions are c = -6 and c = 3.
Check to see if these answers work by plugging them into the original equation:
c = -6:
sqrt (-6 + 22) ?= -6 + 2
But, -6 + 2 is a negative number, and you can't get a negative from a square root. So, -6 is extraneous.
c = 3:
sqrt (3 + 22) ?= 3 + 2
5 = 5. So, 3 works.
The answer is: B
No, because u might have to find the mean or mode and the median is always in the middle
Answer:
28 x³ + 48 x² + 62 x + 30
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the polynomial equation
(4 x² + 4x +6)(7x+5)
Multiply
⇒ 4 x² ( 7 x+5) + 4 x ( 7x+5) + 6 (7x+5)
⇒ 28 x³ + 20 x² + 28 x² + 20 x + 42 x + 30
⇒ 28 x³ + 48 x² + 62 x + 30
$56.25, since 25% off can also be written as ÷4, since 25 is a quarter. 75÷4=18.75
75-18.75=56.25. Therefore, the answer is $56.25
