Solve for x: 3x − 2 &gt; 5x + 10. (5 points)<br> 1) x &gt; 6<br><br> 2) x −6
san4es73 [151]

Answer:

x

Step-by-step explanation:

3x-2>5x+10

Add 2 to both sides

3x-2+2>5x+10+2

Simplify

3x>5x+12

Subtract 5x from both sides

3x-5x>5x+12-5x

Simplify

-2x>12

Multiply both sides by -1 (reverse the inequality)

(-2x)(-1)

Simplify

2x

Divide both sides by 2

\frac{2x}{2}

Divide the numbers: \frac{2}{2} =1

=x

Divide the numbers: \frac{-12}{2}

Apply fraction rule: \frac{-a}{b} =-\frac{a}{b}

=\frac{12}{2}

Divide the numbers: \frac{12}{2} =6

=-6

x

Factor Completely.<br> 12k^2-16k-60
faltersainse [42]

Answer:

4(k - 3)(3k + 5)

Step-by-step explanation:

Given

12k² - 16k - 60 ← factor out 4 from each term

= 4(3k² - 4k - 15) ← factor the quadratic

Consider the factors of the product of the coefficient of the k² term and the constant term which sum to give the coefficient of the k term

product = 3 × - 15 = - 45 , sum = - 4

Factors are - 9 and + 5

Use these factors to split the middle term

3k² - 9k + 5k - 15 → ( factor the first/second and third/fourth terms

= 3k(k - 3) + 5(k - 3) ← factor out (k - 3)

= (k - 3)(3k + 5)

Hence

12k² - 16k - 60 = 4(k - 3)(3k + 5) ← in factored form
