Answer:
Graph C is the only one that has a positive slope; the slope of y = 4x - 4 is +4.
Step-by-step explanation:
Graph C is the only one that has a positive slope. Looking carefully, we see that the slope of the line in C is +4.

Answer:
X= 9
Step-by-step explanation:
16x-15 = 30+11x
16x-11x =30+15
5x = 45
x=45/5
x=9
I think that should be it
Answer:
Step-by-step explanation:
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 3
B = -2
C = -10
B2 - 4AC =
4 - (-120) =
= 124
Applying the quadratic formula :
2 ± √ 124
x = —————
6
√ 124 simplified
The prime factorization of 124 is
2•2•31
To be able to remove something from under the radical, there have to be 2 instances of it
√ 124 = √ 2•2•31 =
± 2 • √ 31
√ 31, rounded to 4 decimal digits, is 5.5678
So now we are looking at:
x = ( 2 ± 2 • 5.568 ) / 6
Two real solutions:
x =(2+√124)/6=(1+√ 31 )/3= 2.189
or:
x =(2-√124)/6=(1-√ 31 )/3= -1.523
