The two equations can be solve using substitution method.
<span>-3x + y = -11 .....................(1)
2X + 5y = 30 .....................(2)
</span>
From equation 1,
-3x + y = -11
y=-11+3x
y=3x-11
Substitute the vale of y in equation 2 with y=3x-11,
2X + 5y = 30
2x + 5(3x-11) = 30
2x + 15x - 55 = 30
17x -55 = 30
17x = 30+55
17x = 85
x =85/17
= 5
From the equation 1,
y=3x-11
Since x = 5,
y = 3(5) - 11
= 15 - 11
= 4
Answer;
x = 5
y = 4
Total amount after three years
= $8.360
Explanation:
Given -
Principal amount
p = $.8,000
Rate of interest
r = 1.5%
Duration
n = 3 years
Total amount after three years = Principal amount + Interest amount
Total amount after three years
= p + (pnr) = 8000 + (8000×1.5100×3) = 8000 + 360 = $8.360
Total amount after three years
= $8.360
An Irrational Number is one which cannot be put into rational form (i.e. a fraction)
Pretty much, any decimal that is not in any particular order is irrational. Of this list, <span>√ 8 is the only one that generates a non-repeating decimal, so that is your irrational number.
