-5 < -4
Step-by-step explanation:
The last comparison is correct one.
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
{x = -1/2 , y = -1
step-by-step explanation:
solve the following system:
{2 x + y = -2
{10 x - 3 y = -2
in the first equation, look to solve for y:
subtract 2 x from both sides:
{y = -2 x - 2
substitute y = -2 x - 2 into the second equation:
{10 x - 3 (-2 x - 2) = -2
10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:
{16 x + 6 = -2
in the second equation, look to solve for x:
subtract 6 from both sides:
{16 x = -8
divide both sides by 16:
{x = -1/2
substitute x = -1/2 into the first equation:
{y = -1

answer: {x = -1/2 , y = -1
