Answer:

Step-by-step explanation:

so we use the equation y2-y1=m(x2-x1)

let's say (-3,1) is point 1 and (-5,8) is point 2

we plug in what we know

8-1=m(-5-(-3))

subtracting a negative is the same as adding so -5 - (-3) = -2

7=-2m

divide both sides by -2

-7/2=m

-3.5=m

so slope intercept form is y=mx+b

we know the slope (m) but we still need the "b" which is the y-intercept.

so you pick whichever point you want (I'm going to chose point 1 but it doesn't matter) and plug it in

1=-3.5(-3)+b

1=10.5+b

-9.5=b

so the equation would be y=-3.5x-9.5

4 The perimeter of a regular pentagon is represented by the expression 35d - 25.
Komok [63]

The equivalent expression to Daryl's expression is -5 + 7d ⇒ d

Step-by-step explanation:

In a regular polygon of n-side

  • All sides are equal in lengths
  • All angles are equal in measures
  • Its perimeter is n × the length of one side

∵ The polygon is a pentagon

∴ n = 5

∵ The pentagon is regular

∴ The lengths of its 5 sides are equal

∵ Its perimeter = 5 × length of one side

∵ Its perimeter = 35d - 25

- Equate the two sides of the perimeter

∴ 5 × length of one side = 35d - 25

- Divide both sides by 5

∵ 35d ÷ 5 = 7d and 25 ÷ 5 = 5

∴ The length of one side = 7d - 5

Daryl's expression is 7d - 5

Now lets check the answers

a. 35d - 25 ⇒ No

b. 7d - 15 ⇒ No

c. 5(35 - 25) ⇒ No

d. -5 + 7d ⇒ Yes

e. (35d - 25) ⇒ No

The equivalent expression to Daryl's expression is -5 + 7d

ANSERR GIVE ME ANSWERS PLS
Zarrin [17]

Answer:

Concept: Mathematics

When you multiply a number by something to the 10 power of something then you move whatever place of the exponential to the right if its positive and left if it's negative.

  1. 1.365 × 10^1
  2. You see its positive 1 hence we move one space to the right
  3. Our answer is now 13.65

You keep doing the same thing

  1. 1.365 × 10^2
  2. 136.5

Lastly

  1. 1.365 ×10^3
  2. 1365
