Answer:
- 6x / 5
Explanation:
Multiplicative inverse is the negative reciprocal of a fraction.
<h3>Answer:</h3>
F (3x, 3y)
<h3>Explanation:</h3>
Dilation about the origin multiplies each coordinate by the dilation factor. For some coordinates (x, y), dilation by a factor of 3 means the new coordinates are ...
... 3×(x, y) = (3x, 3y)
_____
<em>Comment on the problem</em>
The way the problem is worded, you expect an answer choice that will be specific to the coordinates of point A. There are none.
Instead, the answer choices are generic, corresponding to dilation of a point (x, y) by a factor of 3, translation up and to the right by 3, dilation by a factor of 1/3, and translation down and to the left by 3.
Answer:
- 10
- 15ab
Step-by-step explanation:
1. The square of the binomial is ...
(* -2m)^2 = *^2 -4m* +4m^2
Matching terms, you find ...
*^2 = 100
-4m* = -40
Both of these equations tell you the value of * is 10.
___
2. Same deal. Multiply ou the square and see what you have.
(3a +2.5b)^2 = 9a^2 +15ab +6.25b^2
The term missing on the right side of the given equation is 15ab.
Step-by-step explanation:
Evaluate f(x) = x^2 - 5x , where f(4)
=> f(4) = (4)^2 - 5(4)
=> f(4) = 16 - 20
=> f(4) = -4.
