Which of the following values of y will result in a true statement when substituted into the given equation? y + 4.2 = 3.4

A. y = -0.8
B. y = 2.2
C. y = 4.3
D. y = 5.2

A. -0.8

Step-by-step explanation:

non of the other answers will work because they are positive.

A, y = -0.8

Step-by-step explanation:

To solve this, you have leave the y alone.

Subtract 4.2 from both sides.

y + 4.2 - 4.2 = 3.4 - 4.2

y = 3.4 - 4.2

y = -0.8

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
