3x + ky = 8
djyliett [7]

Answer:

a) 3x + ky = 8

ky = 8 - 3x

x – 2ky = 5

x - 2(8 - 3x) = 5

x - 16 + 6x = 5

7x = 21

x = 3 (shown)

b) x-2ky = 5

sub x = 3, y = 1/2

3-2k(1/2) = 5

-2k = 2

k = -1

The formula A=P(1+r)^2 gives the amount A in dollars that P dollars will grow to in 2 years at interest rate R (where r is given
Likurg_2 [28]
P=presne amount=5000
A=furutre amount which you want to be 5304.50

solve for r

5304.50=5000(1+r)^2
divide both sides by 5000
1.0609=(1+r)^2
sqrt both sides (remember to get positive and negative roots)
+/-1.03=1+r
minus 1 both sides
+/-1.03-1=r

+1.03-1=r=0.03=3%
-1.03-1=r=-2.03=false, no negative percents

answer is 3%

Is 5 1/2 rational or irrational ?
-Dominant- [34]

Answer:

Rational

Step-by-step explanation:

It is a rational number because any number that can be rewritten as a simple fraction is a rational number. This means that natural/counting numbers, whole numbers and integers, like 5, are all part of the set of rational numbers as well because they can be written as fractions, as are mixed numbers such as 1 ½.
