Answer: tan(x)=\±\frac{3}{4}

Step-by-step explanation:

You know that sin(x)=\frac{3}{5} and you can identify that. Then:

sin^2(x)=(\frac{3}{5})^2

sin^2(x)=\frac{9}{25}

Remember that:

cos^2(x)=1-sin^2(x)

Then cos^2(x) is:

cos^2(x)=1-\frac{9}{25}\\\\cos^2(x)=\frac{16}{25}

Apply square root to both sides to find cos(x):

\sqrt{cos^2(x)}=\±\sqrt{\frac{16}{25}}\\cos(x)=\±\frac{4}{5}

Remember that:

tan(x)=\frac{sin(x)}{cos(x)}

Then, this is:

tan(x)=\frac{\frac{3}{5}}{\±\frac{4}{5}}

tan(x)=\±\frac{3}{4}

5 less than a number is equivalent to 1 more than three times the number
kifflom [539]

Answer:

x-5=3x+1 (x=-3)

Step-by-step explanation:

5 less (_-5)

than a number (x)

is equivalent to (=)

1 more than (+1)

than three times the number (3x)

combine them all to get x-5=3x+1

extra:

add 5 to each side x=3x+6

subtract x from each side 0=2x+6

subtract 6 from each side -6=2x

divide each side by 2 -3=x

Simplify completely quantity 4 x squared minus 32 x plus 48 all over quantity 3 x squared minus 17 x minus 6.
Yuki888 [10]

For this case we must simplify the following expression:

\frac {4x ^ 2-32x + 48} {3x ^ 2-17x-6}

Simplifying the numerator, dividing all the terms by 4, we have:

x ^ 2-8x + 12

We factor by looking for two numbers that when added together give -8 and when multiplied by 12. These are: -6 and -2

-6-2 = -8\\-6 * -2 = 12

So, we have to:

x ^ 2-8x + 12 = (x-6) (x-2)

Simplifying the denominator:

We rewrite -17x as -18x + x:

3x ^ 2-18x + x-6

We factor the highest common denominator of each group:

3x (x-6) +1 (x-6)

We factor the polynomial by factoring the highest common denominator (x-6):

(x-6) (3x + 1)

So, we have to:

3x ^ 2-17x-6 = (x-6) (3x + 1)

Substituting in the original expression we have:

\frac {(x-6) (x-2)} {(x-6) (3x + 1)} = \frac {x-2} {3x + 1}

ANswer:

\frac {4x ^ 2-32x + 48} {3x ^ 2-17x-6} = \frac {x-2} {3x + 1}

Did I solve correctly?
faust18 [17]

5 {x}^{2}  + 536 = 651 \\ 5 {x}^{2}  = 651 - 536 =115  \\  {x}^{2}  =  \frac{115}{5}  = 23 \\ x =  +  -  \sqrt{23}  =  +  - 4.79
