\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{We have the points (-4, 0) and (4, -4)}\\\\\text{substitute:}\\\\m=\dfrac{-4-0}{4-(-4)}=\dfrac{-4}{8}=-0.5\\\\\text{therefore we have the equation of the given line in slope-intercept form:}\\y=-0.5x+b.\\\\\text{Parallel lines have the same slope.}\\\\\text{Therefore the line equation from question is y = -0.5x + b.}

\text{It passes through the point (2, 3).}\\\\\text{Substitute the coordinates of the given point  to the equation of the line}:\\\\3=-0.5(2)+b\\3=-1+b\qquad|+1\\4=b\to b=4\\\\\text{therefore}\ y=-0.5x+4\qquad|+0.5x\\\\0.5x+y=4\qquad|\cdot2\\\\\boxed{x+2y=8\to B.)}

Find the sum of -6/ab + a^2/b^2
Ymorist [56]

Answer:

\frac{1}{ab^{2} } (a³ - 6b)

Step-by-step explanation:

\frac{-6}{ab} + \frac{a^{2} }{b^{2} }

= \frac{-6b + a^{3} }{ab^{2} }

= \frac{1}{ab^{2} } (a³ - 6b)

Answer:

Below in bold.

Step-by-step explanation:

c) 3 x (9^2)^3/4 x ((81^3)^5/6

= 3 x 81^3/4 x 81^15/6

= 3 x 81^(3/4 + 15/6)

= 3 x 81^13/4

= 3 x 3^13

= 3^14

= 4,782,969.

f) (5x^-1y^2)^-2 / (25 x^2 y - 1)^2

=  5^-2 x^2y^-4 / 625 x^4y^-2

=  5^-2 x^-2 y^-2 / 5^4

= 5^-6 x^-2y^-2

= 0.000064x^-2y^-2.

Here are 10 test scores: 30, 74, 76, 77, 78, 79, 80, 80, 82, 84. The mean of these scores is 74.
creativ13 [48]
We add up all those numbers (excluding 30) and divide by the number of numbers (9). This results in 78.8 (round up to 79).

79-74 = 5. So the mean has increased by 5 points. (C)
