Mathematics
1 answer:
Troyanec [42]2 years ago
6 0

Answer:

x = 39.1

Step-by-step explanation:

mean = average off all the numbers =

sum of the numbers / amount of numbers.

35 = sum of the #'s / # of #'s

35 = 100.9 + x / 4

35 × 4 = 100.9 + x / 4 × 4

140 = 100.9 + x

140 – 100.9 = 100.9 + x – 100.9

39.1 = x

x = 39.1

Which graph matches the equation ?
gulaghasi [49]

Answer:

Pretty sure it's the first one. It's the only one with the correct y-intercept and has a positive slope.

This is in fancy form, so you want to simplify it:

y = 3/4(x+4) - 6

Multiply it all,

y = 3/4x + 3/4(4) - 6

y = 3/4x + 3 - 6

y = 3/4x - 3

The first one matches.
