Mathematics
1 answer:
aalyn [17]2 years ago
6 0

Answer:

2=x

Step-by-step explanation:

Substitute the

−x−1 for y to get −x−1=−2x+1

Add x to −x and −2x

to get

−1=−1x+1

Subtract 1 from 1 and −1

to get

−2=−1x

Divide both sides by

-1

to get

2=x

Two students went to the schools clinic with fevers Isabell had a temperature of 103.78 and Bryan had a temperature that was 2.3
jeyben [28]

Answer:

1)  The temperature of Bryan  is 101.39°

Step-by-step explanation:

Here, the Temperature of Isabell is given =   103.78 degrees

Now, the temperature  of Bryan = Iaabell's Tempt.  - 2.36

So, temperature  of Bryan  =   (103.78  - 2.36)  degrees

                                              =  101.4  degree

Hence, the temperature of Bryan =    101.4  degree

So, the most appropriate option is 101.39°

Triangle F G E is shown. Angle F E G is a right angle. The length of hypotenuse F G is 15.2 meters and the length of F E is 9 me
ololo11 [35]

Answer:

<h3>sin(x) = StartFraction 9 Over 15.2 EndFraction</h3>

Step-by-step explanation:

From the triangle given;

The length of hypotenuse FG =  15.2 meter

Since FE is the side facing the angle FGE, then;

the length of FE is opposite = 9 meters

m<FGE = x

According to SOH CAH TOA

sin theta = opp/hyp

sin m<FGE =  FE/FG

Substitute the given values

sin x = 9/15.2

Hence the correct answer is sin(x) = StartFraction 9 Over 15.2 EndFraction

For their twentieth wedding anniversary, Richard and Sylvia had a party for several of their best friends. Things were going alo
kompoz [17]

Answer:

Richard is older

Step-by-step explanation:

We can set up an inequality for both statements.

Let r equal Richard's age and s equal Sylvia's age.

"I am older than my wife."

Since Richard is speaking, the inequality would look like this:

r > s

This means Richard is older than Sylvia.

"I am younger than my husband."

Since Sylvia is speaking, the inequality would look like this:

s < r

This means that Sylvia is younger than Richard.

We can flip one inequality to "see" them from the same perspective.

Let's use s < r

To make it so that we can see the relationship from Richard's perspective, flip the entire inequality.

s < r

to

r > s

The inequality from the first quote is identical to this one!

Therefore, Richard is older than Sylvia.
