Answer:

D. -3 and  4

Step-by-step explanation:

-12 = -3 x 4

-3  + 4 = 1

so

x^2 + x - 12

=  (x - 3)(x + 4)

ANSWER

D. -3 and 4

EXPLANATION

The given quadratic trinomial is

{x}^{2}  + x - 12

To factor this we need to find two factors of -12 that sum up to 1, the coefficient of x.

We can see from the table that, when p=-3 and q=4, then p+q =1.

The trinomial can now be factored as:

{x}^{2}  + x - 12 = (x - 3)(x + 4)

The correct answer is D.

What is the relationship between the ratios? 5/8 and 8/10 Drag and drop to complete the statement.
Lubov Fominskaja [6]

Answer:

NOT PROPORTIONAL

Step-by-step explanation:

The given two fractions are: $ \frac{5}{8} $ and $ \frac{8}{10} $.

Proportional fractions are those which have the same value when to reduced to the simplest form.

Consider two fractions $ \frac{p}{q} $ and $ \frac{x}{y} $.

We say they are proportional if $ p : q = x : y $.

Or, if $ py = qx $ then we can say the fractions are proportional.

Here the fractions are:  $ \frac{5}{8} $ and $ \frac{8}{10} $.

LHS: 5 X 10 = 50.

RHS: 8 X 8 = 64.

Clearly they are not equal. So, we can say these two fractions are not proportional.

Convert the point-slope form to slope-intercept form y– 4 = -3(x + 2)
artcher [175]

Answer:

y = -3x - 2.

Step-by-step explanation:

y - 4 =  -3(x + 2)

y - 4 = -3x - 6

y = -3x - 6 + 4

y = -3x - 2.

Ana and Chuyen are exploring
Alina [70]
Ana would be farther from sea level because if you look at a number line and say 0 is the sea level Ana would be farther because -30 is farther away than -12.
Please give brainiest if possible.
