Answer:
Everything will be split in threes. You can do this by either multiplying the cost by 1/3 or dividing by 3.
Step-by-step explanation:
B. A rotation of 90 clockwise followed by a translation of 6 units to the left
C. A translation of 5 units to the left followed by a dilation of a factor of 2
D. A reflection across the y-axis followed by a rotation of 180counterclockwise
Answer:
Option C
Step-by-step explanation:
Whenever transformation is done we have either reflection on a given line, or rotation about a fixed point or a dilation by a scale factor
Whenever transformations are reflections over a line, the original figure size will not be altered and hence we have congruent figures.
Similarly for rotations also original figures will not be altered
But whenever a dilaton by a scale factor other than 1 is done, we have either shrink or dilation of original figure.
So there is a chance of getting similar figure but not congruent figure.
So here we find option C is right answer
Answer: 1 square down, 2 squares right
2 squares up, 1 square right
Step-by-step explanation:
B. 6x5 + 4x4 – 7x3 + 5x² + 8x
C. 6x4 + 4x3 - 7x2 + 5x + 8
D. 8 + 5x + 7x2 - 4x3 + 6x4
E. 8 + 5x – 7x2 + 4x3 + 6x4
Answer:
Options (C) and (E)
Step-by-step explanation:
Given polynomial is,
6x⁴+ 4x³- 7x² + 5x + 8
So all the polynomials which are (look alike) similar in terms of degree and number of terms to the given expression will be equivalent.
Option (A).
It's a monomial. So not the answer.
Option (B).
6x⁵ + 4x⁴ - 7x³ + 5x² + 8
This polynomial is a 5th degree polynomial, will not be equivalent to the given polynomial expression with 4 degree.
Option (C).
6x⁴ + 4x³ - 7x² + 5x + 8
All the terms and signs between the terms of this expression are similar to the given polynomial expression,
Expression will be equivalent to the given polynomial expression.
Option (D)
8 + 5x + 7x² - 4x³ + 6x⁴
= 6x⁴- 4x³ + 7x² + 5x + 8
Both are similar in number of terms and degree but signs between the terms are different.
Therefore, both the expressions are will not be equivalent.
Option (E).
8 + 5x - 7x² + 4x³ + 6x⁴
= 6x⁴ + 4x³ - 7x² + 5x + 8
Since, both the polynomials are similar so they are equivalent.
