Elvira and Aletheia live 3.1 miles apart on the same street. They are in a study group that meets at a coffee shop between their
Sophie [7]

Answer:

  • Elvira's speed: 3.0 mph
  • Aletheia's speed: 2.4 mph

Step-by-step explanation:

Let "e" and "a" represent the speeds of Elvira and Aletheia, respectively. Then the total distance they cover is ...

  distance = speed × time

  (1/2)e + (2/3)a = 3.1

And the relationship between their speeds is ...

  e - a = 0.6

__

To solve this system, we can double the first equation and subtract the second to get ...

  2(1/2e +2/3a) -(e -a) = 2(3.1) -(0.6)

 7/3a = 5.6 . . . . . . . . . . simplify

  a = (3/7)(5.6) = 2.4 . . . multiply by 3/7

  e = a +0.6 = 3.0 . . . . . Elvira's speed is 0.6 mph more than Aletheia's

Elvira's walking speed is 3.0 miles per hour; Aletheia's is 2.4 miles per hour.

Can someone please help me with this and thank you:)
erica [24]

Answer:

B

Step-by-step explanation:

A is not correct because 1 does not equal 1/4 +1/4.

B is correct because 1/4*1 does equal 1/5. (and all the other ones)

C is not correct because 1 does not equal 1/4*1/4

D is not correct because 1/4 does not equal 1-1/4

Which of the following ordered pairs could be the y-intercept of the function?
kolbaska11 [484]
I would probably say (0,0) just because (5,0) falls on the x-axis and not on the y-axis and the other are just regular plotting coordinates. (0,0) is the only one that falls on the y-axis although it still falls on the x-axis as well

Plaese help! been stuck on apex all day
Kruka [31]
Ok, so it seems
erm

ok, even and odd
it is an odd one because the power is odd (3rd degree)
so then the ends go in different directions
and since leading coefient (5 in the 5x^3) is positive, it goes from bottom left to top right
so

A is false
B is false
C and D are true
answer is C and D
