The line passes through (-8, -4) and (6,-4).<br> What’s the equation

galben [10]

Answer:

y = -4

Step-by-step explanation:

- Plug the values into the slope formula.

y2 - y1 / x2 - x1

-4 - (-4) / 6 - (-8)

0 / 14

= 0

y = 0x + b

-4 = 0(6) + b

-4 = 0 + b

-4 = b

Which of the statements below are true? Select all that apply.

creativ13 [48]

A is true: the absolute value of 0.92 is close to 1, and 0.92 is positive.
B is false: correlation can also be negative.
C is false: the absolute value of -.17 is closer to 0 than 1; therefore, it is a weak correlation.
D is true: the absolute value of .01 is very close to 0, meaning that there is no significant correlation.
E is true: correlation can range from -1 (perfect negative) to 1 (perfect positive).
F is false: it measures the strength and direction between two numerical variables!
In conclusion, A, D, and E are true.

2x^3-x^2+x-2 factorize

bekas [8.4K]

Answer:

$(x-1)(2x^2+x+2)$

Step-by-step explanation:

Factorize:

$f(x)=2x^3-x^2+x-2$

<u>Factor Theorem</u>

If f(a) = 0 for a polynomial then (x - a) is a factor of the polynomial f(x).

Substitute x = 1 into the function:

$\implies f(1)=2(1)^3-1^2+1-2=0$

Therefore, (x - 1) is a factor.

As the polynomial is cubic:

$\implies f(x)=(x-1)(ax^2+bx+c)$

Expanding the brackets:

$\implies f(x)=ax^3+bx^2+cx-ax^2-bx-c$

$\implies f(x)=ax^3+(b-a)x^2+(c-b)x-c$

Comparing coefficients with the original polynomial:

$\implies ax^3=2x^3 \implies a=2$

$\implies (b-a)x^2=-x^2 \implies b-2=-1 \implies b=1$

$\implies -c=-2 \implies c=2$

Therefore:

$\implies f(x)=(x-1)(2x^2+x+2)$

Cannot be factored any further.
