Which of the following transformations are used when transforming the graph of the parent function...

hram777 [196]

1. 1st transformation is translation the parent function $y=\log_5x$ 6 units to the right to get the function $y=\log_5(x-6).$

2. 2nd transformation is reflection the function $y=\log_5(x-6)$ over the x-axis. This transformation gives you the function $y=-\log_5(x-6).$

3. 3rd transformation is vertical stretch of the function $y=-\log_5(x-6)$ by a factor of 2 to get the function $y=-2\log_5(x-6).$

Only last two are present in options, then

ernie walks 1/6 mile in 1/12 hour when he walks along the river trail. How many miles per hour does Ernie walk when he hikes on

ohaa [14]

Answer:

2 miles

Step-by-step explanation:

distance=rate*time

d=rt

1/6=r*(1/12)

multiply both sides by 12

12(1/6)=r*(1/12)12

2=r*1

2=r

rate=2 miles per hour

What is the difference? startfraction 2 x 5 over x squared minus 3 x endfraction minus startfraction 3 x 5 over x cubed minus 9

weeeeeb [17]

The difference of the expression $\frac{2x^5}{x^2 - 3x} - \frac{3x^5}{x^3 - 9x}$ is $\frac{2x^5(x + 3) - 3x^5}{x(x - 3)(x + 3)}$

<h3>How to determine the difference?</h3>

The expression is given as:

$\frac{2x^5}{x^2 - 3x} - \frac{3x^5}{x^3 - 9x}$

Factor the denominators of the expressions:

$\frac{2x^5}{x(x - 3)} - \frac{3x^5}{x(x^2 - 9)}$

Apply the difference of two squares to x² - 9

$\frac{2x^5}{x(x - 3)} - \frac{3x^5}{x(x - 3)(x + 3)}$

Take LCM

$\frac{2x^5(x + 3) - 3x^5}{x(x - 3)(x + 3)}$

Hence, the difference of the expression $\frac{2x^5}{x^2 - 3x} - \frac{3x^5}{x^3 - 9x}$ is $\frac{2x^5(x + 3) - 3x^5}{x(x - 3)(x + 3)}$

Can someone plz help me with this problem and plz show work.

motikmotik

Answer:

Step-by-step explanation:

y = 2x + 5

the slope (m) of this line is 2 (which can be written as 2/1)

The slope of a perpendicular line is -1/m (the reciprocal of the slope with the opposite sign)

so m = 2/1 => -1/m = - 1/2 = the slope of a line perpendicular to y = 2x + 5

Ian walked 4 miles in 90 minutes. Bob walked 7 miles in 2.5 hours. Are these rates in proportion? If no, who walked faster?

Yuliya22 [10]

Answer:

<h3>Bob walked faster than Ion.</h3>

Step-by-step explanation:

90/4=22.5

Ian - 1 mile in 22.5 minutes

2x60=120

60/2=30

120+30=150

150/7=21.43

Bob - 1 mile in 21.43
