Answer:
the answer is A or F (both are the same answer which is 40)
Answer:
I think is 4x
Step-by-step explanation:
because nothing changes so x=4x
Answer:
x = -1 and y = -1
Step-by-step explanation:
to solve this equation we say
let
2x-5y=3.......................................... equation 1
4y-x=-3............................................equation 2
from equation 2
4y-x=-3............................................equation 2
4y + 3 = x
i.e
x = 4y + 3 ............................................. equation 3
put x = 4y + 3 in equation 1
2(4y +3) - 5y = 3
8y + 6 -5y = 3
3y +6 = 3
3y= 3-6
3y -3
divide both sides by the coefficient of y which is 3
3y/3 = -3/3
y = -1
put y = -1 into equation 3
x = 4y + 3 ............................................. equation 3
x = 4(-1) + 3
x = -4 + 3
x = -1
therefore the value of x = -1 and y = -1 respectively
It is important to know that probabilities are defined insed the range [0,1], which means they cannot be outside that set of values.
<h2>Hence, -0.56, square root of 2, 1.23, and 5/3 can't be probabilities because they are outside the range of values.</h2>
