Answer:

3/6 and 5/10

Explanation:

Given the fraction 1/2:

(a)Multiply the numerator and denominator by 3

$\frac{1}{2}\times\frac{3}{3}=\frac{3}{6}$

An equivalent fraction is 3/6.

(b)Multiply the numerator and denominator by 5:

$\frac{1}{2}\times\frac{5}{5}=\frac{5}{10}$

An equivalent fraction is 5/10.

Ok sweetheart, the easy way to solve these problems is to change them to all the same form for example "decimal" after that you sort them! just don't forget to remember which is which!!! so this is how you solve.

squared 25, 4.26, 3 1/5 2^3,2.58
i converted each so your answer is A.

Which equation represents exponential decay? * a y=3^x-4 b y=2(4)^x c y=1/2(3)^x d: y=6(1/3)^x

yuradex [85]

The equation which represents exponential decay is y= $6(1/3)^{x}$

Given four equations : 1)y= $3^{x} -4$ , 2) y= $2(4)^{x}$ , 3) y= $3^{x}/2$ , 4) y= $6(1/3)^{x}$ .

Equation is relationship between two or more variables expressed in equal to form. Equations of two variables look like ax+by=c. Exponential equation look like $a^{x}$ .

Decay means when x value increases ,the y value decreases.

We haveto put 3 values for x in the equations to check.

1)y= $3^{x} -4$

put x=0,y=-3

put x=1, y=-1

put x=2, y=5

No,itdoes not represents exponential decay.

2) y=2 $4^{x}$

put x=0,y=2

put x=1, y=8

put x=2, y=32

No,it does not represents exponential decay.

3) y= $3^{x}/2$

put x=0,y=0.5

put x=1, y=1.5

put x=2, y=4.5

No,it does not represents exponential decay.

4)y=6 $(1/3)^{x}$

put x=0,y=6

put x=1, y=2

put x=2, y=0.67

Yes ,it represents exponential decay.

Hence the equation which represents exponential decay is y=6 $(1/3)^{x}$ .
