Answer:
it will be y=3x +? i forgot how to find b
Step-by-step explanation:
X=-6 and x=1/3 are both correct values so A and D
Answer:
(A) -8
Step-by-step explanation:
∆=b^2 -4ac= (-4)^2-4(2)(3)= -8
Since discriminant<0, then the equation has no roots.
Answer:
$8.27
Step-by-step explanation:
First we need to find the tip. We know it was 18% of the total. So...
x (the variable we need to find) 18%
__ = ___
10.08 (the total bill including tip) 100%
cross multiply
100x = 181.44
-------------------- (divide by 100 to get x by itself)
100
x = 1.81 (The 18% tip that was given)
So now we know how much the tip was, we subtract it from the bill
10.08 - 1.81 = $8.27
Answer: 0.000008
Step-by-step explanation:
So it says 10 to the -6 power...
10*-10*-10*-10*-10*-10*-10
0.000001
Then you multiply that by 8
0.000008
Hope this helps!
