you can easily just check the given answers,or find the answer yourself.I teach you the second :)

since the point (1,1) is in the domain and the point (4,1) is not, for 1<=x<4 we have y=1. (number one if incorrect, we put it aside...)

the point (6,2) is not in the graph and that line (y=2) starts from to point (4,2) ... this means that the third one is not the answer...

so far,the answer is found,but you can do the same for the last two lines to make sure that we've found the correct answer.

the ages of sari and justin can be represented as two consecutive integers. The product of their age is 72. Justin is older. wri

Lelechka [254]

The age of Sari is 8 years.

The age of Justin is 9 years.

Explanation:

Let x denote the age of Justin.

Let y denote the age of Sari.

Given that the product of their age is 72.

Thus, it can be written in equation as

$xy=72$

Since, the numbers x and y are consecutive integers and Justin is older, then, it can be written as,

$x=y+1$

Therefore, the two equations are $xy=72$ and $x=y+1$

<u>The ages of Sari and Justin:</u>

The ages of Sari and Justin can be determined by solving the two equations.

Let us solve the equations using substitution method.

Substituting $x=y+1$ in the equation $xy=72$ , we have;

$(y+1)y=72$

$y^2+y=72$

$y^2+y-72=0$

Factoring the equation, we get;

$(y-8)(y+9)=0$

$y=8 \ or \ y=-9$

The value of y cannot be negative.

Thus, $y=8$ is the value of y.

Substituting $y=8$ in the equation $x=y+1$ , we have;

$x=8+1$

$x=9$

Thus, the value of x is 9.

Therefore, the age of Sari is 8 years and the age of Justin is 9 years.

PLEASE HELP!! WILL GIVE BRAINLIEST ANSWER TO THE FIRST PERSON

KatRina [158]

Answer:

See below.

Step-by-step explanation:

So, from the figure, we can see that US is the combined length of UT and TS. In other words:

$UT+TS=US$

We are given their equations. Substitute them:

$(x-3)+(12)=(3x-11)$

And this is our answer to 4.

Now, solve for x. Add on the left:

$x+9=3x-11$

Subtract -3x from both sides:

$-2x+9=-11$

Subtract 9 from both sides:

$-2x=-20$

Divide both sides by -2:

$x=10$

So, for 5, the answer is 10.

And we're done!
