Answer:
Step-by-step explanation:
20x - 44z = 84
528x + 44z = 1012
548x = 1096
x= 2
48(2) + 4z = 92
96 + 4z = 92
4z = -4
z = -1
(2, -1)
Step-by-step explanation:
||x-5|+2|≤3
-3 ≤ (|x-5| +2) ≤ 3
-5 ≤ |x-5| ≤ 1
|x-5| ≥ -5 => not required
|x-5| ≤ 1
-1 ≤ x-5 ≤ 1
4 ≤ x ≤ 6
the Solutions:
{4≤ x ≤ 6}
Answer:
The slope is how far up or down/ Left or right the line moves
Step-by-step explanation:
Think rise over run
Example 1y=1x+1
Slope is the number in front of the x
So 1y = <u>1</u>x +1
up 1 over 1
Negative numbers go down.
This is the concept of application of compound interest, to calculate the amount I will have after the 5th deposit we proceed as follows;
A=p(1+r/100)^n
where;
A=future amount
p=principle
r=rate
n=number of years
thus substituting the values in our formula we get:
A=3,100(1+8.5/100)^5
A=3,100(1+0.085)^5
A=3100(1.085)^5
A=4,666.34
The amount of money after 5 years will be $4,666.24
This is what you get when you simplify the problem.
