Answer:
11. D
12. C
Step-by-step explanation:
11. We need to find 2 numbers where the sum is -15 and the product is 56. Those two numbers are -7 and -8 so the answer is D.
12. Like the previous problem, we need to find 2 numbers where the sum is -9 and the product is 14. Those two numbers are -2 and -7 so the answer is C.
Y = 3x + 7....slope is 3, y int is 7
y = 3x + 2...slope is 3, y int is 2
when the slopes are the same, but the y intercepts different, then it is a parallel line with no solutions.
little tip :
slopes same, y int different, = no solution
slopes same, y int same = infinite solutions
slopes different, y int different = 1 solution
Answer:
x=3b/(2+a-b)
Step-by-step explanation:
x(2+a)=b(x+3)
2x+ax=bx+3b
2x+ax-bx=3b
x(2+a-b)=3b
x=3b/(2+a-b)
