Find the equation of the straight line which passes through each of the following pairs of points.

Tems11 [23]

Answer:

y = 3x + 1

Step-by-step explanation:

First, find slope:

$y2 - y1 / x2 - x1$

$10 - 4/ 3 - 1 = 6 / 2 = 3$

Then, put the equation into point-slope form using the point (1, 4):

$y - y1 = m(x - x1)$

where m is the slope

y - 4 = 3(x - 1)

If you want to put this into slope-intercept form, it would be

$y-4=3(x-1)\\y - 4 = 3x - 3\\y = 3x + 1$

Compute each quotient using the identities you discovered in this lesson.x^4-16/x-2

luda_lava [24]

Answer:

The quotient will be $(x^2+4)(x+2)$

Step-by-step explanation:

We have given the equation $\frac{x^4-16}{x-2}$

We have to find the quotient

From algebraic equation we know that $a^2-b^2=(a+b)(a-b)$

So $\frac{x^4-16}{x-2}=\frac{(x^2)^2-4^2}{x-2}=\frac{(x^2+4)(x^2-4)}{x-2}=\frac{(x^2+4)(x+2)(x-2)}{x-2}=(x^2+4)(x+2)$

So the quotient will be $(x^2+4)(x+2)$

Factor completely 10xy + 3y + 20ax + 6a.

stiv31 [10]

10 xy + 3y + 20 ax + 6a = y(10x+3) + a(20x+6) = y(10x+3)+2a(10x+6)=
(y+2a)(10x+3)

Margin of error formula:
ME = z * (Sigma) / √ n
z = 1.96 for a 95 % confidence interval;
Sigma = 3 ( the population standard deviation )
n = 500
ME = 1.96 * 3 / √500 =
= 1.96 * 3 / 22.36 =
= 5.88 / 22.36 = 0.263
Answer:
The margin error for a 95% confidence interval is 0.263.
