This is what I put "I used the m=y2-y1/ x2-x1 to solve for the slopes (-1,3) and (1,2) has a slope of -1/2. (1,2) and (-3,-1) has a slope of 3/4. (-1,3) and (-3,-1) has a slope of 2. I plotted this on a graph and came to the conclusion that is was an acute isosceles triangle."

The product of 3x and (3x+1) is a t least 35
Leokris [45]
Product means the sum of two things i.e. the product of 1 and 2 is 3 <span>(1 + 2 = 3)

So the product of 3x and (3x+1) can be written as:
35 < 3x + 3x + 1
^ Greater than 35 i.e. at least 35
35 < 6x + 1
34 < 6x
34/6 < x
17/3 < x
5.67 (2dp) < x

15 _ { 10 } + X _ { 2 } = 11011 _ { 2 }​
KatRina [158]

11011₂ = 2⁴ + 2³ + 2¹ + 2⁰ = 27

15 + <em>x</em>₂ = 27

<em>x</em>₂ = 12 = 8 + 4 = 2³ + 2² = 1100₂

What are some Solutions to the linear equation?: 3x+y=-8
svetlana [45]

9514 1404 393

Answer:

  (0, -8), (1, -11), (-1, -5)

Step-by-step explanation:

It is convenient to solve for y and choose values of x.

  y = -3x -8 . . . . . subtract 3x from both sides of the equation

Now, any integer value of x you choose will result in an integer value of y. Often, it is convenient to choose values near zero.

  x = -1, y = -3(-1) -8 = 3 -8 = -5 . . . . solution: (-1, -5)

  x = 0, y = -3(0) -8 = -8 . . . . solution: (0, -8)

  x = 1, y = -3(1) -8 = -11 . . . . solution: (1, -11)
