Answer:

- x² + 8x - 15

Step-by-step explanation:

Given

(5 - x)(x - 3)

Each term in the second factor is multiplied by each term in the first factor, that is

5(x - 3) - x(x - 3) ← distribute parenthesis

= 5x - 15 - x² + 3x ← collect like terms

= - x² + 8x - 15 ← in standard form

What is y=x by a vertcal stretch of 5

kakasveta [241]

Answer: The vertical stretch of 5 in the equation y = x is defined by $y=5x$ .

Explanation:

The given equation is,

$y=x$

It can be written as,

$f(x)=x$

The function is defined as $S\cdot f(x)$ .

If $S\geq 1$ , then the function has a vertical stretch by a factor of S units.

If $0$ , then the function has a vertical shrink by a factor of S units.

Since we have to find the vertical stretch of 5 in the equation y = x.

$y=5f(x)$

$y=5x$

The below figure shows the graph of y = x and $y=5x$ .
