Answer:

1) False. 2) False.

Step-by-step explanation:

1) False. 2) False.

1) is false because it says, "A total of 40 students can type from 0-59 words per minute." 0-14w=5s, 15-29w=10s, 10-44w=14s, and 45-59w=20s. w= words per minutes s= number of students (BTW) 5+10+14+20=54 not 40

2) is false because it says, "The number of students who typed 45-59 words per minute is equal to the number of students who typed 15-39 and 0-14."

45-59w=20s

15-39w=10s and 0-14w=5s

10s+5s=15s

20s>15s

What is the solution of this system 4x+2y=-2<br> -5x+y=34
Kitty [74]

Answer:

x=-5

Step-by-step explanation:

  1. Solve the bottom equation for y
  • You would just add 5x to both sides so that it cancels out leaving y = 5x + 34

    2. Put your new y equation into your top equation (4x + 2y = -2).  It should now be 4x + 2(5x + 34) = -2.

    3. Then, solve for x.

  • Distribute the 2 into 5x and 34. (Should now be 4x + 10x + 68 = -2).
  • Add the like terms - 4x and 10x. (Now 14x + 68 = -2).
  • Subtract 68 from both sides to get 14x on its own. (Now 14x = -70).
  • Divide both sides by positive 14 to get x on its own and the answer as to what x represents. (x = -5).

Hope that helps!
