Answer:


Step-by-step explanation:

(  -2x³ + x - 5) × ( x3 - 3x - 4)

= ( -2x³)×( x3 - 3x - 4) +(x)×( x3 - 3x - 4) - (5)( x3 - 3x - 4)

= - 2x^6  +6x^4 +8x³ + x^4 - 3x² -4x - 5x³ +15x + 20

= - 2x^6  +7x^4 +3x³-3x²+11x +20

(-3,0);slope=2/3 slope intercept form
Step2247 [10]
Y = mx + b, m = slope and b = y-intercept

Because you don't have the y-intercept, you take the equation and replace x and y with the values given, then solve for b and replace b in the original equation with the value found.

y = 2/3x + b
0 = (2/3)(-3) + b
0 = -2 + b
2 = b

y = 2/3x + 2 is the answer

Look at the set of quadrilaterals in the coordinate plane shown below.
morpeh [17]

The true statement about the set of quadrilaterals in the coordinate plane is B. Because quadrilateral ABCD can be reflected across the x -axis, then rotated 90° counterclockwise about the origin, and then dilated about the origin by a scale factor of 2 to obtain quadrilateral A'B'C'D' , then quadrilateral ABCD is similar to quadrilateral A'B'C'D'.

<h3>What is a quadrilateral?</h3>

A quadrilateral is a polygon having four sides, four angles, and four vertices.

In this case, because quadrilateral ABCD can be reflected across the x -axis, then rotated 90° counterclockwise about the origin, and then dilated about the origin by a scale factor of 2 to obtain quadrilateral A'B'C'D' , then quadrilateral ABCD is similar to quadrilateral A'B'C'D'.
