What are the zeros of the parabola whose equation is y = x2 + 8x + 15
Sedbober [7]

9514 1404 393

Answer:

  (1)  -5 and -3

Step-by-step explanation:

Descarte's rule of signs tells you the lack of sign changes among the coefficients means there are <em>no positive real roots</em>. That eliminates all answer choices except the first one.

__

If you want to go to the trouble, you can factor the equation:

  y = (x +3)(x +5)

These factors are zero when x = -5 and x = -3.

K is the midpoint of JL JK=3x-1 and KL=2x+8 find JL
Masteriza [31]

Answer:

JL = 52

Step-by-step explanation:

It is given in the question that K is the midpoint of JL.

So, JK = KL ......... (1)

Now, given that, JK =3x - 1 and KL = 2x + 8  

Therefore, from equation (1), we can write  

3x - 1 = 2x + 8

⇒ x = 9

So, JK = 3x - 1 = 3(9) -1 = 26 and KL = 2x + 8 = 2(9) + 8 = 26

Hence, JL = JK + KL = 26 + 26 = 52. (Answer)

Simplify 12n-2n⁴-10n-2n⁴+n<br><br>a. 4n⁴+3n<br>b. 3n<br>c. -4n⁴+3n<br>d. -n¹¹
Serjik [45]

The answer is C. -4n⁴+3n.


Separate the expression by its like terms.

12n-2n⁴-10n-2n⁴+n

12n+(-10n)+n=3n

-2n⁴+-2n⁴=-4n⁴


The simplified expression comes out to -4n⁴+3n.

When R2 is more useful than R in linear regression?
valina [46]
<span>Answer: Multiple R is the correlation between y and y^ in a regression model. It is always non-negative, but has no nice interpretation as a proportion of variance, unlike its square. I can't think of too many uses for it and only know of one stat package that routinely reports it, SPSS. Bivariate correlation only tells you about two variables at a time (though you can use partial correlation to remove other variables).</span>
