4w-7k=28
-7k+4w+-4w=28+-4w
-7k=-4w+28
-7k/-7=-4w+28/-7
k=4/7w-4

Answer:
10 in
Step-by-step explanation:
6² + 8² = c²
36 + 64 = c²
100 = c²
√100 = c
10 = c
Remember, to be a function, all elements in the domain should correspond to one element in the range.
The domain is the x coordinate, range is the y coordinate.
The domain we can solve for as the set {4.2, 5, 7}. The range is the set {0, 1.5, 2.2, 4.8}.
But we see that an element in the domain corresponds to more than one element in the range, thus making it not a function.
Answer:
(1.5, -2)
Step-by-step explanation:
First subract -3 from 6 to find the total distance of the line segment.
6 - (-3)
Two negatives make a positive
6 + 3
9 units distance
Knowing this, the midpoint is 4 1/2 units away from either end. (1/2 * 9 = 9/2 = 4 1/2 units) Either add 4.5 to -3, or subtract 4.5 from 6 (keep the -2 though, as this line is straight!) to get the coordinates of the midpoint.
-3 + 4.5
-3 + 3 + 1.5
(1.5, -2)
6 - 4.5
6 - 4 - 0.5
2 - 0.5
(1.5, -2)
The midpoint of segment RS is (1.5, -2).
Answer:
450 miles
Step-by-step explanation:
there is a 2 hr difference in betwen them. when you take 450 there is a 150 mile difference from 300 so when you divide 150 by 2 you get 75 so you do about 75 miles an hr so you can go 450 miles in 6 hr's.
