Answer:

y = 1x - 3

Step-by-step explanation:

(1, -2), (4, 1)

Slope formula:

4 - 1 = 3

3/3 = 1

Slope = 1

y = 1x + b

1 = 1(4) + b

1 = 4 + b

-3 = b

Identify the equation of the parent function y=x^3 that is horizontally streched by a factor of 1/5 and reflected over the y axi

choli [55]

Answer:

$y=\frac{-x^{3}}{125}$

Step-by-step explanation:

As we know that,

<em>'Horizontal stretch, stretches the function left or right on the x-axis'. </em>

The general form of horizontal stretch is given by 'f(kx)', where 0<k<1 is the factor by which function is stretched horizontally.

Since, the function $y=x^{3}$ which is stretched by a factor of $\frac{1}{5}$ .

The new function is $y=(\frac{x}{5})^{3}$ i.e. $y=\frac{x^{3}}{125}$ .

<em>Further, the function is reflected over y-axis.</em>

That is, the reflected function is $y=\frac{(-x)^{3}}{125}$ i.e. $y=\frac{-x^{3}}{125}$ .

Hence, the required function is $y=\frac{-x^{3}}{125}$ .

Find the percent of increase for 4 to 7. round to the nearest tenth if necessary. also someone please explain how to do this.

dem82 [27]

Answer:

75%

Step-by-step explanation:

The percent increase is calculated as

percent increase = $\frac{increase}{original number}$ × 100%

increase = 7 - 4 = 3, thus

% increase = $\frac{3}{4}$ × 100% = $\frac{3(100)}{4}$ = 75%

Solve the formula, d=r*t for t

larisa [96]

Hello there!

$d=rt$

Explanation:

↓↓↓↓↓↓↓↓↓

First you had to do is switch sides of the equation.

$rt=d$

Then you divide by t from both sides of the equation.

$\frac{rt}{t}=\frac{d}{t} ; t\neq 0$

Simplify it should be the correct answer.

$r=\frac{d}{t} ; t\neq 0$

Answer⇒⇒⇒⇒⇒ r=d/t or t≠0

Hope this helps!
