-7,3. if you use slide and divide
andreyandreev [35.5K]3 years ago
6 0

Answer:

(-7 , 3)

Step-by-step explanation:

3x^2 + 12x = 63 //Subtract 63 on both sides.

3x^2 + 12x - 63 = 0 //Common factor 3.

3(x^2 + 4x - 21) = 0 //Divide both sides by 3.

(x^2 + 7x - 3x - 21) = 0

x(x + 7) - 3(x + 7) = 0

(x + 7) (x - 3) = 0

x = -7 and 3

Solution: (-7, 3)

Given: -6x &lt; 36. Choose the solution set. {x | x &lt; -6} {x | x &gt; 6} {x | x &gt; -6} {x | x &lt; 6}.
grin007 [14]

The correct answer is this inequality {x | x > -6}

What does a math inequality look like?

The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3.

Given that:

-6x < 36

we multiply -1 on both the sides

6x > -36

divide 6 on both the side

x > -6

Hence the correct answer is this inequality {x | x > -6}.

Part one: Sequence and Series
ASHA 777 [7]

Answer:

- 57

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a + (n - 1)d

where a is the first term and d the common difference

Here a = 13 and d = - 2.5, thus

a_{29} = 13 + (28 × - 2.5) = 13 - 70 = - 57
