What are the zeroes of the function y=3(x-a)(x+b) in terms of a and b?

juin [17]

Answer:

a, -b

Step-by-step explanation:

When x is a, the function becomes

$f(a)=3(a-a)(a+b)$

as you see, a-a is 0, and as your whole function is multiplied by this, it makes it 0.

$f(-b)=3(-b-a)(-b+b)$

As you see -b+b is 0, and once again, this would make the whole function 0.

Toucans and blue-and-yellow macaws are both tropical birds. The length of the toucan in the picture to the right is about two t

Sergeu [11.5K]

Answer:

The length of the blue-and-yellow macaw is 42 in

Step-by-step explanation:

Let

x ----> the length of the toucan in inches

y ----> the length of the blue-and-yellow macaw in inches

we know that

$x=\frac{2}{3}y$ ----> equation A

$x=28$ ----> equation B

substitute equation B in equation A and solve for y

$28=\frac{2}{3}y$

Multiply by 3 both sides to remove the fraction

$28(3)=2y$

Divide by 2 both sides

$y=\frac{28(3)}{2}=42\ in$

therefore

The length of the blue-and-yellow macaw is 42 in
