Answer:

y = -4x + 13

Step-by-step explanation:

m = -4, (-2, 5)

you're going to put this into point-slope form, which is y - y1 = m (x - x1).

y - 5 = -4 (x - (-2))

distribute the -4 (and the two negatives make a positive)

y - 5 = -4x + 8

add five on both sides to get y on its own, on the left, adding 5 to the five cancels out five.

and you get:

y = -4x + 13

The total snowfall for listed 10 days is 349 cm.

Further explanation:

The sum of snow fell each day will give us the total snowfall for 10 days.

Given:

Snow fell on 10 days:

14 cm, 13 cm, 7 cm, 3 cm, 11 cm, 14 cm,

28 cm, 108 cm, 84 cm, 67 cm

So,

$Total\ snowfall\ for\ 10\ days\ listed=14+13+7+3+11+14+28+108+84+67\\=349\ cm$

The total snowfall for listed 10 days is 349 cm.

Plz help <br> I will be giving extra 50 points

Klio2033 [76]

it isn't possible to just give extra points in a simple and reliableway. anyways, let's starts.

a. is simple, just put the terms in order

r² +6r -5

because:

${r}^{2} + {6r}^{1} + {5r}^{0}$

anything to the power of 0 equals 1,

because it's the same as r/r, and 5 * r/r = 5*1

b. same logic as above

a²b² -5ab +33

-c³ +ab +d +9

-9y^5 - 2x³y²z +4x² +10x +1

^5 = to the power of five, it's the fastest way to type it without the special math input tool.

hope it helps you

The perimeter of the rectangle is 28 units.

Answer:

since we can't see the image, I'm just giving it a try

if it's wrong, it's fine for you to delete it

(see below)

Step-by-step explanation:

if one of the length is 5.6 units then the other will be 5 units

if one of the length is 4 units then the other will be 7 units

if one of the length is 2 units then the other will be 14 units

if one of the length is 1.86666666667 units then the other will be 15 units

if you're looking of an area, it might be 7 units

and I think that's all I've got

(hope it helps)
