0.29x-0.25=0.43x+0.03

1 answer:

7 0

Add both sides by 0.25:

$0.29x = 0.43x + 0.28$

Subtract both sides by 0.43x:

$-0.14x = 0.28$

Divide both sides by -0.14 to get x by itself:

$0.28 \div -0.14 = 2$

$x = -2$

The value of x is -2.

Which set of parametric equations represents the following function y=square root of x+3

Irina18 [472]

The given equation is:

$y= \sqrt{x+3}$

We have to find, which of the given set of parametric equations given in the options, result in the above equation:

The correct answer would be option A.

The equations in option A are:

$x(t) = 5t \\ 
y(t)= \sqrt{5t+3}$

From first equation we can see that 5t is equal to x. Using the value of 5th in second equation, we get the equation as:

$y= \sqrt{x+3}$

Therefore, the correct answer is option A

. Samantha is three times as old as Jason. The sum<br> of their ages is 56 years. How old is each?

8_murik_8 [283]

Step-by-step explanation:

let age of samantha be 3x and age of jason be x.(since samantha is three times as old as jason)

Now,

3x+x=56 (sum of their ages is 56)

or 4x=56

or x=56/4

or x=14

therefore age of samantha=3x=3×14=42

age of jason = x = 14
