using the two points find the slope then write the equation in slope intercept form AND standard form. (-6, 4) and (0, 3)
Paraphin [41]

so to find the slope we do y2- y1/ x2-x1

plug in the coordinates: (-6,4) (0,3)

3-4/ 0--6

3-4/0+6

= -1/6

Then using the formula of slop intercept form: y=mx+b........ use one of the coordinates to plug in

4= -1/6x+b...... multiply -6/1 on both sides of equation ( you do this so -1/6 and -6/1 can cancel out)

-24=b........ Use b to plug in y=mx+b---------> y= -1/6x-24

identify the initial amount,a,and the growth factor,b,in each exponential function.Break b into (1+r)where r is the rate of grow
Alla [95]

Given function : y=1.05(1.46)^x

We need to identify a " initial amount", b "growth factor", r " rate of growth".

We know, exponential growth formula

y=a(b)^x, where a is initial amount, b is growth factor. On comparing with given function let us find values of a and b.

y=1.05(1.46)^x ⇔ y=a(b)^x.

We can see a= 1.05 and b = 1.46.

Now, b=1+r.

Therefore, 1+r =1.46.

Subtracting 1 from both sides, we get

1+r-1 =1.46-1

r = 0.46.

On converting 0.46 into percentage, we get

0.46 × 100 = 46.

Therefore, intial amount a = a= 1.05 , growth factor b = 1.46, and the rate of growth r= 46%.

The correct option is (A) x^6 + x^5 - 2x^4  - 2x^3 + 3x^2 + 6x - 9 

Explanation:
The product of two polynomials:
(x^3 + x^2  -3)(x^3 - 2x + 3)

Row1:   x^6       x^5      -3x^3
Row2: -2x^4   -2x^3      6x
Row3:  3x^3     3x^2      -9

Add all of the above rows:
x^6 + x^5 - 3x^3 -2x^4 - 2x^3 + 6x + 3x^3 + 3x^2 -9

x^6 + x^5 - 2x^4  - 2x^3 + 3x^2 + 6x - 9 (Option A)
