Check your solutions algebraically and identify any extraneous solutions. Write it step by step.

Answers

Answer:

x = 4, x ≠ -1

Step-by-step explanation:

√3x + 4 = x

(√3x + 4)² = x² (Square both sides to get rid of the radical.)

3x + 4 = x²

0 = x² - 3x - 4 (Set everything to 0 by moving everything to one side.)

0 = (x - 4)(x + 1) (Factor.)

x = 4   x = -1

Now we need to check for extraneous solutions:

√3(4) + 4 = 4

√12 + 4 = 4

√16 = 4

4 = 4

√3(-1) + 4 = -1

√-3 +4 = -1

√1 = -1

1 ≠ -1

-1 is an extraneous solution.

If Ryan gives 4/9 of his 36 cards to Josiah, how many cards does he give Josiah?

Answers

Answer:

16 cards

Step-by-step explanation:

Answer:

Ryan gave 16 cards to Josiah.

Step-by-step explanation:

First we will divide 36 by 9.

36/9 = 4

We know that 1/9 of 36 is 4.

1/9 + 1/9 + 1/9 + 1/9 = ?

4 + 4 + 4+ 4 = ?

4 * 4 = 16

4/9= 16

Heather made $299 for 13 hours of work.
At the same rate, how much would she make for 18 hours of work?

Answers

Answer:

$414

Step-by-step explanation:

We know that Heather made $299 for 13 hours of work.

So, to find how much Heather will make for 18 hours of work at the same rate, we can write and solve for the following proportion:

[tex]\frac{299}{13}=\frac{x}{18}[/tex]

Notice that we align the rates vertically and the measurements horizontally (dollars in the numerator and hours in the denominator).

So, to find how much Heather will make for 18 hours, we will solve for x. Cross-multiply:

[tex]13x=5382[/tex]

Divide both sides by 13:

[tex]x=\$414[/tex]

So, Heather will make $414 for 18 hours of work.

And we're done!

What integer represents the total charge of 7 electrons?

Answers

the integer that represents the total charge of 7 electrons is -1.The total charge of electrons is given by the formula:

total charge = number of electrons x charge of each electron

what are electrons ?

Electrons are subatomic particles that carry a negative electric charge. They are one of the fundamental particles that make up atoms, along with protons and neutrons. Electrons are found in shells or energy levels that surround the atomic nucleus

In the given question,

The total charge of electrons is given by the formula:

total charge = number of electrons x charge of each electron

The charge of an electron is a fundamental constant, which is equal to -1.602 x 10⁻¹⁹ Coulombs. Therefore, the total charge of 7 electrons can be calculated as:

total charge = 7 x (-1.602 x 10⁻¹⁹) C

total charge = -1.1214 x 10⁻¹⁸ C

Note that the charge of an electron is negative because it has an opposite charge to the positively charged protons in an atom. Therefore, the total charge of 7 electrons is also negative. To express this charge as an integer, we need to convert it to scientific notation and round to the nearest whole number. Rounding to the nearest whole number gives:

total charge = -1 x 10⁻¹⁸ C

Therefore, the integer that represents the total charge of 7 electrons is -1.

Answer:

x = -4 2/13

x = -4.15384615385

x = -54/13

(they are all the same, just in different formats)

Step-by-step explanation:

(5/3x) + 6 = (2/9)x

first, make all "x"s have a common denominator

(5/3) = (15/9)

so

(5/3)x = (15/9)x

(15/9)x + 6 = (2/9)x

solve using inverse operations

(15/9)x + 6 = (2/9)x

-(2/9)x         -(2/9)x

(13/9)x + 6 = 0

            -6    -6

(13/9)x = -6

to get rid of the fraction, multiply the entire equation by the denominator

(13/9)x = -6

*9          *9

13x = -54

/13     /13

x = -4 2/13

x = -4.15384615385

x = -54/13

We can remove the parenthesis now. Also, now we combine like terms. There are no other variables in the equation, so we leave the 12x alone. Combine the +8 and the -6 to get +2. This leaves the equation at:

Not enough information to make a conclusion. What writers struggle to express through numerous newspaper columns, the cartoon manages in a pointed one-liner. Little wonder then, that the first thing most of us like to see when we pick up a newspaper is the cartoon. Simple though it may seem, making a cartoon is an art that requires a combination of hard work, training and a good sense of humour. Cartoonists say that the cartoons that make us laugh the most are in fact the cartoons that are hardest to make. Even celebrated cartoonists like R.K.Laxman admit that making a cartoon is not a piece of cake. Laxman says he has to wait for over six hours, which includes spending a lot of time scanning newspapers and television channels before any idea strikes him.So how does one become a cartoonist? Which of us has the talent to make it? How can we master the rib-tickling strokes and the witty one-liners? How can we make people smile or laugh? There are few colleges or schools for cartoonists. Most cartoonists come from art colleges, while some learn the craft on their own. Most established cartoonists are of the view that no institute can teach you to make a cartoon. "You can pick up the craft, you may learn to sketch and draw in institutes, but no one can teach anyone how to make a good cartoon," says Uday Shanker, a cartoonist with Navbharat Times. While basics, like drawing and sketching can be learnt in an art college, and are important skills, these alone, do not make a good cartoonist. Because it's a question of one's creativity and sense of humour; two qualities one simply may not have. The advice established cartoonists give is that just because you can sketch, don't take it for granted that you will become a cartoonist.
