For this case we must indicate the factors of the following expression:

x ^ 2-12x-20

To factor we must find two numbers that when multiplied result in -20 and when added, result in -12.

There are no two numbers that meet this condition. Thus, the expression is not factorizable with rational numbers.

Answer:

The expression is not factorizable with rational numbers.

Please help!!! Which equation is in point-slope form and is depicted by the line in this graph?
Blizzard [7]
Y-y1=m(x-x1)
a point on the line is (x1,y1) and the slope is m

so
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so

points (-2,3) and (3,0)
slope is (0-3)/(3-(-2))=-3/(3+2)=-3/5
a point is (3,0) Or (-2,3)

so it could be
y-0=-3/5(x-3) or y-3=-3/5(x-(-2)) which is equal to y-3=-3/5(x+2)
that's the answer

14/2 three equivalent ratios
Anna71 [15]

Answer:

Three equivalent ratios of  \frac{14}{2} are \frac{7}{1}, \frac{21}{3} and \frac{28}{8}.

Step-by-step explanation:

We are given a fraction \frac{14}{2}.

We need to find the three equivalent ratios/fractions of \frac{14}{2}.

The common factor of 14 and 2 is 2.

So, dividing top and bottom by 2, we get

14÷2 = 7 and 2÷2 that is \frac{7}{1}.

Multiplying \frac{7}{1} fraction by a common number 3 in top and bottom, we get

7 × 3 = 21

1 × 3 = 6

So, we get another equivalent fraction \frac{21}{6}.

Multiplying \frac{7}{1} fraction by a common number 3 in top and bottom, we get

7 × 4 = 28

1 × 4 = 4

So, we get another equivalent fraction \frac{28}{4}.

Therefore, three equivalent ratios of  \frac{14}{2} are \frac{7}{1}, \frac{21}{3} and \frac{28}{4}.
