Answer:

y=\frac{1}{25}x-\frac{31}{25}

Step-by-step explanation:

y=-25x-5

You can get the gradient of the line perpendicular to this as you know the products of their gradients will be -1.

-25*m_{perpendicular}=-1\\m_{perpendicular}=\frac{1}{25}

We have a gradient, and a point (6, 1), so we can now substitute our known values into the line equation.

(y-y_0)=m(x-x_0)

y-1=\frac{1}{25} (x-6)

Rearrange for y and collect terms.

y=\frac{1}{25}x-\frac{6}{25}-1\\\\y=\frac{1}{25}x-\frac{31}{25}

Answer:

a: 162

b: 142

Step-by-step explanation:

a: december 1=2

a: december 2=6

a: december 3 = 6 x 3 = 18

a: december 4 = 18 x 3 =54

a: december 5 = 54 x 3 =162

~ triples the number of newspapers means "x3" ~

so on the last day, 162 newspapers

B: sum up all the newspapers:

2 + 6 + 18 + 54 + 162

= 8 + 18 + 54 + 162

= 26 + 54 + 162

= 80 + 162

= 242 all in total newspapers

You receive a gift card for an
vesna_86 [32]
Answer: $20

Explanation: If you have $17.70 after 2 games and $14.25 after 5, you do 17.70-14.25; which equals $3.45 so in 3 games you spend $3.45 now divide that by 3 to determine the unit value; which equals $1.15, so you spend $1.15 on every game now times that by 2 which is $2.30 and add that to $17.70 to see the original amount of money on the card which was $20

Carrie can inspect a case of watches in two hours. Jerry inspects a case in five hours. After inspecting a case for a half an ho
masha68 [24]
Write the hours as ratio

Carrie : Jerry
   2      :    5

Put this ratio in words, we say 'for every two hours Carrie takes to inspect a case, Jerry would need 5 hours'

Carrie has done 30 minutes on a case before taking a break. It means Carrie has 1.5 hours left on the case if she was to continue it. 

We need to work out the proportion of the time Jerry would take in comparison to 1.5 hours that Carrie would have taken.

First, we divide 2 by 1.5 ⇒ \frac{2}{1.5}= \frac{4}{3}

Then we divide 5 by 4/3 ⇒ \frac{5}{4/3} = \frac{5*3}{4} =3.75 hours

Jerry would have taken 3.75 hours to finish the rest of the case

BYU QUESTION GEOMETERY HELP(photo)I don't know
Tatiana [17]

A fellow BYU courser I see.

Now, I am in the same course as you, but shouldn't there be a "None of the Above" option? (I only finished 1.1 so I don't really know.) I think that is correct.

Based on the picture (I know the picture is almost never drawn to scale but still) I think these line segments aren't parallel.

Also, I think the actual proof involves the Alternate Exterior Angles theorem, and those angles in this case are angles ∠BFC and ∠FCE which aren't listed.
