What is y
kogti [31]

Step-by-step explanation:

Looks like you want all equations converted into slope-intercept form.

  • 2x + y = 2 ⇒ y = -2x + 2
  • x + 2y = 4 ⇒ 2y = - x + 4 ⇒ y = - 1/2x + 2
  • 2x - y = 2  ⇒ y = 2x - 2
  • x - 2y = 4  ⇒ 2y = x - 4 ⇒ y = 1/2x - 2

PLS HELP! ASAP!
KATRIN_1 [288]

Answer:

Your answer is C, 10.7cm

Step-by-step explanation:

The two flat sides of the figure are 3 cm, so that part of the perimeter = 6cm

3cm is the radius of what would be a whole circle. We'll calculate the circumference, then divide by 4.

Circumference = (2)(pi)(r)

C = (2)(3.14)(3)

C = 18.84

18.84/4 = 4.71

Add 4.71 to the 6 cm above, = 10.71

Let me know if you have questions about this.

Michael reads 12 pages of a book in 18 minutes,8 pages in 12 minutes and 20 pages in 30 minutes. Is this a proportional relation
Gelneren [198K]

Answer:

y = 1.5x

Step-by-step explanation:

What you would do is divide all of the minutes by the amount of pages to find how long for each rate for one page. (ex. 18/12, michael reads 1 page in 1.5 minutes. 12/8, michael reads 1 page in 1.5 minutes. 30/20, michael reads one page in 1.5 minutes) Therefore, yes it is proportional, and the equation is y=1.5x (there is no y intercept)
