1 gallon for $3 is the better deal because you're getting twice as much for the same price
∛-512 = -8 . . . . . . . . . . matches the 3rd selection
Answer:
Step-by-step explanation:
substitute (1) to (2):
add x to both sides
subtract 5 from both sides
substitute the values of x to (2):
Given:
The function is:
To find:
The value of 
.
Solution:
We have,
Putting 
, we get
On combining like terms, we get
Therefore, the required function is .
Answer:
The coordinates are (0,b)
Step-by-step explanation:
Here, we want to find the coordinates of the midpoint F
as we can see, F is between A and B
we proceed to use the midpoint formula
The midpoint formula is;
(x,y) = (x1 + x2)/2, (y1 + y2)/2
(x1,y1) = (-3a, b)
(x2,y2) = (3a, b)
The substitution of these values will thus yield;
(-3a + 3a)/2, (b + b)/2
= (0/2), (2b/2)
= (0, b)
