Answer:
Step-by-step explanation:
Given the expression 20 - x.
The value of x determines if the value of the expression would increase, decrease or stay the same. When the value of x decreases, the value of 20 - x increases. When the value of x increases, the value of 20 - x decreases. And when the value of x does not change, 20 - x remains the same.
When greater values of x is subtracted from 20, you will have lower value left. Therefore, as x increases, the value of the expression 20 - x will decrease.
Answer:
The solution is (-4,-1)
Step-by-step explanation:
The solution to the system is where the two graphs intersect.
The lines intersect at x = -4 and y = -1
The solution is (-4,-1)
Step-by-step explanation:
let the total students be x then
25/100x=9
x=9×100/25
x=9×4
x=36
so total students are 36
Step-by-step explanation:
from the question:R=x^2/y
where x=3.8*10^5
y=5.9*10^4
it then mean
R=(3.8*10^5)^2/5.9*10^4
=144400000000/59000
=2447457.63
