First you need to put it into y=mx+b format and which is 1/2x + 2 =y. The y intercept should be b in the equation y=mx +b so y=2. The x-intercept should be when y=0 and x equals a number which is x=-4. X-intercept=-4 and y-intercept=2.
Answer:
Step-by-step explanation:
volume of a pyramid is V=(lwh)/3
Term to be added is: + 121/4
t^2 + 11t + 121/4
(t + 11/2) (t + 11/2)
<span>The right function is f(x)=3x^3-10x^2-81x + 28
You can realize that 7 is a root because it is in all the answers.
So you can divide the polynomial by x - 7. If you do it you can find that the quotient is 3x^2 + 11x - 4
Now you can use the quadratic formula to find the other two roots.
If you do it, you will find they are x = 1/3 and x = -4.
So the answer is option A) 7, -4, 1/3
And the polynomial can be written as (x - 7)(x + 4) (x -1/3)
