Multiply the values of a and c together;
9*30= 270 <— find prime factors of this
270= 3*3*3*5*2
Now find a way to add these factors in different ways to give 33 (b value)
We can try (3*3*2)+(3*5)=?
18+15=33
Now that you know the numbers, break down the b value.
9x^2+18x+15x+30
9x(x+2)+15(x+2) <— make sure the brackets are the same
(9x+15)(x+2) <— check if this expands to the initial answer
Hope I helped :)
Answer:
7) C) 7
8) D) y=-2x+3
Step-by-step explanation:
7) 3x-1/9(27)=18
3x-3=18
3x=21
x=7
8) y=-2x+3
The question is incomplete. But this explanation will help you very much.
1) Regarding the function

,
its graph always passes through the points (1,0) and (a,1).That is due to the properties of logarithm function:
a)

b)

<span>
That in turn is due to the properties of the exponential functions.
a^0 = 1 and a^1 = a
</span>
2) Regarding the y-axis.
The function

will never touch the y-axis, because the logaritm of zero is not defined. So
the graph lies to the righ of the y-axis (i.e. the domain of the function is x > 0)
Answer:
option 4
Step-by-step explanation:
using the equation stated above
1st term = -6+(1-1=0)*(6)=-6
4th term= -6+(4-1=3)*6=12
10th term= -6+(10-1=9)*6=48
