If (-1, y) lies on the graph of y=2^2x then y=

zubka84 [21]

Answer:

y is 1/4 when x is -1 if I did interpret your equation right. Please see that I did.

I believe the equation to be $y=2^{2x}$ . If you meant $y=2^2x$ , please let me know.

Thanks kindly.

Step-by-step explanation:

If (-1,y) lies on the graph of $y=2^{2x}$ , then by substitution we have:

$y=2^{2\cdot -1}$ .

We just need to simplify to determine y:

$y=2^{2 \cdot -1}$

Multiply the 2 and -1:

$y=2^{-2}$

Use reciprocal rule for exponents to get rid of the negative:

$y=\frac{1}{2^2}$

$2^2$ just means $2(2)$ :

$y=\frac{1}{2(2)}$

$y=\frac{1}{4}$ .

The price of a mobile phone decreased from $375 to $250 during a clearance sale. What is the percent of decrease in the price?

Tresset [83]

So decrease is 375-250=75

so convert 75/375 to percent
percent means part out of 100 so
x/100=x%

divide 125/375=0.3333/1

multiply by 100/100=33/100=33%

the answer is 33% or B

How do you solve 3 x 3 1/3

Butoxors [25]

Answer:

Step-by-step explanation:

Turn 3 1/3 into an improper fraction.

(3*3) + 1 = 10/3 so 10/3 is the same as 3 1/3

Turn the 3 into an improper fraction of 3/1

Now multiply 10/3 * 3/1 multiplying straight across: 10*3/3*1=30/3=10
