3.<br> If r=9.b=5, and g=-6, what does (r +b-8)(b + g) equal?

VLD [36.1K]

Answer:

-6

Step-by-step explanation:

r = 9, b = 5, g = -6

Plug these values into (r + b - 8)(b + g)

[(9) + (5) - 8]*[(5) + (-6)]

Combine like terms in the brackets

[6]*[-1]

6 times -1 equals -6, so that is your answer

Suppose line n has a slope of 5/7 and passes through (4,8). what is the equation for n in point-slope form?

Olegator [25]

Answer:

$\large\boxed{y-8=\dfrac{5}{7}(x-4)}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

We have the slope $m=\dfrac{5}{7}$ and the point $(4,\ 8)$ .

Substitute:

$y-8=\dfrac{5}{7}(x-4)$
