Answer:
Step-by-step explanation:
you need to turn the second y equation into the correct format, so it needs to be y=. Subtract the 1 from the left side and but it on the right side. Your equation should y=3x-1. To graph this on paper, you would go 1 down on the y axis, then rise (go up) 3 and run ( go over) one.on a calculator plug it into the y1 function and y2 function and then press graph.
To divide mixed number, convert to improper fractions and divide them
(a/b)/(c/d)=(a/b)(c/d)=(ac)/(bd)
to multiply fractions, multily top by top and bottom by bottom
(a/b)(c/d)=(a times c)/(b times d)
2 y = - x - 12 y = x + 5
- x - 1 = x + 5- 2 x = 5 + 1- 2 x = 6x = - 6 : 2x = - 32 y = - 3 + 52 y = 2y = 1The solution is ( - 3 , 1 ).Answer: x = - 3.
