Answer:

x=6, x=−5 or x=9

Explanation:

f(x)=(x−6)(x+5)(x−9)

If all of the linear factors are non-zero, then so is their product f(x).

If any of the linear factors is zero, then so is their product f(x).

So the zeros of f(x) are precisely the values of x which make at least one of the linear factors 0, namely: 6, −5 or 9.

Y=4x+8x, Solve for x. It's x=y/12, I just need to know how to work it out.

Scrat [10]

Step-by-step explanation:

<h2>Answer:-</h2>

$\tt{y = 4x+8x}$

First, we need to add up the x.

We know that 4+8 = 12, so

$\tt{4x+8x=12x}$

Now, equating it to y,

$\tt{y = 12x}$

Now, if I multiply $\tt{\dfrac{1}{12}}$ on both sides,

I get,

$\tt{\dfrac{y}{12}= \dfrac{\cancel{12}x}{\cancel{12}}}$

Now, as 12 got cancelled , I got the final answer as

$\boxed{\tt{x =\dfrac{y}{12}}}$

Hope it helps :)

Find the gradients of line a and b

gayaneshka [121]

Answer:

Gradient of A: 2

Gradient of B: -1

Step-by-step explanation:

Gradient = change in y/change in x

✔️Gradient of A using two points on line A, (2, 5) and (0, 1):

Gradient = (1 - 5)/(0 - 2) = -4/-2

Simplify

Gradient of A = 2

✔️Gradient of B using two points on line B, (0, 5) and (5, 0):

Gradient = (0 - 5)/(5 - 0) = -5/5

Simplify

Gradient of B = -1

HELP! DUE IN A FEW HOURS

Alenkasestr [34]

Answer:

Options (C) and (E).

Step-by-step explanation:

Rotation is a rigid transformation in which size and shape of the figure and image remains the same.

That means angles and sides of the triangles given in the figure will remain same after the transformations given.

Since, the given triangle has been rotated about a point Z, each rotation will share the vertex Z.

And every figure is the transformed form of the given triangle, all four triangles will be congruent.

Options (C) and (E) are the correct options.
