If the parent function is y=1/x describe the change in the equation y=5/x

answer:

see below

step-by-step explanation:

you want the sum of the distances to equal 1900 miles.

they are travelling in opposite directions and therefore the distances will add.

let the number of hours = t

formula

d = r*t

solution

635*t + 325*t = 1900       combine the right

960*t = 1900                     divide by 960

960t/960 = 1900/960

t = 1.98 hours or 1 hour and 58.8 minutes or 1 hour 58 minutes 48 seconds.

without choices, i don't know which answer you want. perhaps even 2 hours is (rounded) close enough        

answer: option a.

step-by-step explanation:

1. dilation is defined as a transformation in which the figure is enlarged or reduced.

2. for dilation you have:

- a scale factor, that determines how much the figure will be reduced or enlarged.

- the center of dilation, which is defined a a fixed point in the plane.

3. if the figure is dilated with a scale factor of 4 and the center of dilation at the origin, you must multiply the coordinates of the original figure bu 4. then:

(x,> (4x,4y)

answer:

the correct answer is 19,25,31

hello from mrbilldoesmath!

answer:

l = 35, w = 25

discussion:

the attachment shows that

p = 2l + 2w = 120  

and

l = 10 + w

2l + 2w = 120                 => substitute the last equation into the first one

2(10 + w) + 2w = 120     =>

20 + 2w + 2w = 120     => combine like terms

20 + 4w = 120               => subtract 20 from both sides

4w = 120 -20 = 100       => divide both sides by 4

w = 100/4 = 25

hence, l = 10 + w = 10 + 25 = 35

you,
