Answer:
x=-2
Step-by-step explanation:
It is a straight line when x=-2 :)
Answer:
400
Step-by-step explanation:
13x - y = 3 .....(1)
x - 6y = -33 ......(2)
eqn (2) × 13
13x - 78y = -429 .....(3)
(3) - (1)
13x - 78y = -429
13x - y = 3
(-). (+). (-)

- 77y = 431
_________________
-77y = 431
y = 431 ÷ -77
y = -5.5
Answer:
14
Step-by-step explanation:
The interquartile range is the value of quartile 3 minus quartile 1.
The "box" part of this diagram has 3 lines, the left most, the middle, and the rightmost.
The leftmost line is Quartile 1. The right most is Quartile 3.
Hence
interquartile range = quartile 3 - quartile 1
Looking at the box plot, we can see that each small line in the number line is 2 units.
The leftmost line (quartile 1 ) is at 1 unit left of 30, so that is 30 -2 = 28
The rightmost line (quartile 3) is at 1 unit right of 40, so that is 40 + 2 = 42
Hence,
Interquartile range = 42 - 28 = 14
Jack needs 72 feet of fencing.
You had to do 4 ft x 18 ft which would give you the answer of 72. To find the area of a rectangle you do length x width.
