Lets analyze the equation:
<span>ax^2 - bx = 0
</span>x(ax - b) = <span>0
</span>Therefore if x = 0, the equation holds no <span>matter about a and b</span>:
0(0a - b) = 0
0 = 0
Answer:
x=24
y=24

We need to multiply 3x-5y+2z by itself.
I break it down by each term. We'll first do 3x. It is positive.
3x(3x-5y+2z)
3x×3x=9x²
3x×-5y=-15xy
3x×2z=6xz
9x²-15xy+6xz
Now -5y.
-5y(3x-5y+2z)
-5y×3x=-15xy
-5y×-5y=25y²
-5y×2z=-10yz
25y²-15xy-10yz
Now 2z.
2z(3x-5y+2z)
2z×3x=6xz
2z×-5y=-10yz
2z×2z=4z²
4z²+6xz-10yz
Now we need to add all of them together.
(9x²-15xy+6xz)+(25y²-15xy-10yz)+(4z²+6xz-10yz)
We need to add like terms.
9x²+12xz+25y²-20yz+4z²-30xy
Now order them by degrees.
25y²+9x²+4z²+12xz-20yz-30xy is the cost.
By applying the concept of transformation, the <em>transformed</em> function g(x) = √[(3/2) · x] is the consequence of applying a <em>stretch</em> factor of 3/2 on the <em>parent</em> function f(x) = √x.
<h3>How to compare two functions by concepts of transformation</h3>
In this question we have a <em>parent</em> function g(x) = √[(3/2) · x] and a <em>transformed</em> function f(x) = √x. Transformations are operations in which parent functions are modified in their relationships between inputs and outputs.
In this case, the difference between f(x) and g(x) occurred because of the application of a operation known as <em>vertical</em> stretch, defined below:
f(x) = g(k · x), k > 0 (1)
Where k is the <em>stretch</em> factor. There is a compression for 0 ≤ k < 1.
By applying the concept of transformation, the <em>transformed</em> function g(x) = √[(3/2) · x] is the consequence of applying a <em>stretch</em> factor of 2/3 on the <em>parent</em> function f(x) = √x. (Right choice: C)
