Which expression is eqivalent to (x^2-3x)(4x^2+2x-9)

Answers

Answer 1
Answer:

For this case we must find an expression equivalent to:

(x ^ 2-3x) (4x ^ 2 + 2x-9) =

We apply distributive property, term by term, taking into account that:- * + = -\n- * - = +\nx ^ 2 * 4x ^ 2 + x ^ 2 * 2x-x ^ 2 * 9-3x * 4x ^ 2-3x * 2x + 3x * 9 =

By definition we have to, to multiply powers of the same base, the same base is placed and the exponents are added:

4x ^ 4 + 2x ^ 3-9x ^ 2-12x ^ 3-6x ^ 2 + 27x =

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

4x ^ 4-10x ^ 3-15x ^ 2 + 27x

Answer:

An equivalent expression is: 4x ^ 4-10x ^ 3-15x ^ 2 + 27x

WILL GIVE BRAINLIEST! Which statement best illustrates using the vertical line test to determine if the graph below is a function of x?

The graph is not a function of x because the line x = 0 intersects the graph at two points.
The graph is a function of x because the line x = 5 does not intersect the graph.
The graph is not a function of x because the line y = 0 intersects the graph at two points.
The graph is a function of x because the line y = 5 does not intersect the graph.

Answer:

The graph is not a function of x because x=0 intersects the graph at two points.

Step-by-step explanation:

The vertical line test is when you draw, well, a vertical line through the graph. the slope of a vertical line is undefined, and the formula written as x=_. So we can eliminate the choices with y=_.

We can clearly see that this graph isn't a function, so we can eliminate the answer choices that say that the graph is a function.

Just in case, draw a line at x=0, to check that it does indeed cross the graph in 2 places.

What is the slope of the line that contains these two points (-2,2) and (3,2)

Answers

We see based on these points that while the x increases by 5, the y does not change. Therefore, the slope is 0/5=0, by the basic slope formula.

In how many lines do the planes containing the walls intersect?

a) 0
b)1
c)2
d)3

Answers

"0" would be the number of lines among the choices given in the question that the planes containing the walls will intersect. The correct option among all the options that are given in the question is the first option or option "A". As the walls are parallel to each other, so the planes containing the walls would never intersect.
