Answer:
slope is 3/5
y intercept (0,0)
Step-by-step explanation:
Answer:
this is six times bigger larger
Answer:
1
Step-by-step explanation:
The function with the given zeros will factor as ...
f(x) = a(x +15)(x^2 +9) . . . . with leading coefficient 'a'
You have ...
f(2) = 221 = a(2+15)(2^2+9) = a(17)(13) = 221a
Then a = 221/221 = 1
The leading coefficient is 1.

<em>Additional comment</em>
As you know, a function with zero x=p has a factor of (x -p). The given zeros mean the function has factors (x -(-15)), (x -3i). and (x -(-3i)). The product of the last two factors is the difference of squares: (x^2 -(3i)^2) = (x^2 -(-9)) = (x^2 +9). This is how we arrived at the factorization shown above.
Answer:
Translation, rotation and reflection
Step-by-step explanation:
Congruent images remain the same.
Translation, rotation and reflection preserve congruence while dilation will not.
4x^2-5x-21 is of the form ax^2+bx+c, a quadratic equation.
so b in this case is -5
