Number one is B, because if you do the equation 2.94(total price)/ 7(number of items) it gives you the answer $0.42 then for number two A=$1.8 B=$1.83 C=1.81 and D=1.82 leaving A with the best price per bottle of juice. Hope this helped!
Answer:
(-1, -1) and (2, 2)
Step-by-step explanation:
Substitute for y in the first equation and solve the quadratic.
x = x^2 -2
x^2 -x -2 = 0 . . . . subtract x
(x -2)(x +1) = 0 . . . .factor
Solutions are the values of x that make these factors be zero:
x = 2, x = -1
Since y=x, the solutions are ...
(x, y) = (-1, -1) and (2, 2)
Using the given information, the length of WZ is 8
<h3>Length of a line </h3>
From the question, we are to find the length of WZ
From the given information,
Y is the midpoint of WZ
and
X is the midpoint of WY
First,
We will create a line that models the given description
<u>W X Y Z</u>
2
From the given information,
XY = 2
Since X is the midpoint of WY
Then,
WX = XY
∴ WX = 2
Thus
WY = WX + XY
WY = 2 + 2
WY = 4
Also,
Y is the midpoint of WZ
Then,
WY = YZ
∴ YZ = 4
Thus,
WZ = WY + YZ
WZ = 4 + 4
WZ = 8
Hence, the length of WZ is 8
