Answer:
38,653
Step-by-step explanation:
The 3, and -4 are the places where you start, then just graph 1/2 and -3 as slope
x = -45.5
y=57
.50x + .75y= 20
x + y= 11.50
Multiply the second equation by -1/2 so we can eliminate x
-.5 (x + y= 11.50)
-.5x - .5 y = -5.75
Add this equation to the first equation
-----------------------------
.25y = 14.25
Divide by .25
.25y/.25 = 14.25/.25
y =57
Now we still need to find x
x + 57 = 11.5
Subtract 57 from each side
x+57-57 = 11.5-57
x = 45.5
b. 180 is the answer
1.4
{(3, –2), (6, 1), (–1, 4), (5, 9), (–4, 0)}
(x, y)
Domain = x
Range = y
Domain = (3, 6, -1, 5, -4)
In case you need the range it is (-2, 1, 4, 9, 0).
Answer: (3, 6, -1, 5, -4)
Hope this Helps!!
