Answer:

Step-by-step explanation:

For example, if f(x)   =  2x   + 7

      then         f(-3) = 2(-3) + 7

                     f(-3) = 1

Find a cubic function with the given zeros.
tester [92]

The cubic function is f(x)=x^3+3x^2-46x-168

Option D is correct

Step-by-step explanation:

We need to find the cubic function with the given zeros -6,7,-4

If -6,7,-4 are zeros of the function then:

x=-6, x=7 and x=-4

=> x+6=0,x-7=0 and x+4=0

Multiplying these terms to find the cubic function:

(x+6)(x-7)(x+4)

Solving:

(x+6)(x-7)(x+4)\\=(x+6)(x(x+4)-7(x+4))\\=(x+6)(x^2+4x-7x-28)\\=(x+6)(x^2-3x-28)\\=x(x^2-3x-28)+6(x^2-3x-28)\\=x^3-3x^2-28x+6x^2-18x-168\\Combining\,\,like\,\,terms:\\=x^3-3x^2+6x^2-28x-18x-168\\=x^3+3x^2-46x-168

So, the cubic function is f(x)=x^3+3x^2-46x-168

Option D is correct

What is the equation of the line that passes through (0, 3) and (7, 0)?
r-ruslan [8.4K]
The answer should be (C):y=(-3/7)x+3 because:

 if you use the slope formula: (Y2-Y1)/(X2-X1) it would look like this:

(0-3)/(7-0) and the slope of the line would be -3/7

then using the slope you just found, plug it into the y=mx+b equation along with one set of coordinates to find b (the y-intercept):

y=mx+b
0=(-3/7)(7)+b
b=3

SO, overall if you put the slope (m) and the y-intercept (b) that you found together, you get the line formula of y=(-3/7)+3

ahrayia [7]
Hey Kid! 

If he has 18 Muffins 6+6=12 and 12+6=18 so that means he has 3 friends and he gave 6 to each of them. 6+6+6=18. 

Hope this helps!
