World Bank's threshold for poverty is $1.25 per person per day.
For a family of four this gives:
Daily income = (number of people) * threshold
Daily income = 4 * $1.25
Daily income = $5
For a year this is:
Yearly income = (daily income) *365
Yearly income = $5 *365
Yearly income = $1825
U.S. poverty threshold is set at $29000. Portion of threshold can be calculated as:

The poverty threshold measured by World Bank is 6.29% of the U.S. poverty threshold.
Solve the following system:
{-3 + 2 x + y = 0 | (equation 1)
{-1 + x + y = 0 | (equation 2)
Express the system in standard form:
{2 x + y = 3 | (equation 1)
{x + y = 1 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{2 x + y = 3 | (equation 1)
{0 x+y/2 = (-1)/2 | (equation 2)
Multiply equation 2 by 2:
{2 x + y = 3 | (equation 1)
{0 x+y = -1 | (equation 2)
Subtract equation 2 from equation 1:
{2 x+0 y = 4 | (equation 1)
{0 x+y = -1 | (equation 2)
Divide equation 1 by 2:
{x+0 y = 2 | (equation 1)
{0 x+y = -1 | (equation 2)
Collect results:
Answer: {x =2 , y = -1
Answer:
14 years old
Step-by-step explanation:
Assume Ray's sister's age is x.
Ray's age is (x/2)+3, i.e (x+6)/2
If Ray is 10yrs old,then
(X+6)/2 = 10,
x+6 = 20
x = 14
Therefore,Ray's siSter's /e is 14years
Answer:
-12
Step-by-step explanation:
plug in -1 into the equation which is going to be (4*-1)3
you multiply what is in the parenthesis first and after is going to be (-4)3
lastly your going to multiply -4*3 and it is going to equal to -12.
I believe it is because it would be he most simplistic answer to be honest because for example 10,8 it is the same as 5,4 so u would put 5,4 because it is simplified so put (2.1,0) as your answer
