Answer:

1, 9

Step-by-step explanation:

You're looking for the values of x where f(x) = g(x). Find the matching f(x) and g(x) values in the table. The value of x on that line is one of the solutions.

M is directly proportional to r2 <br> When r=2, m=14<br> Work out the value of m when r=12

Genrish500 [490]

we have M is durectly porpotional to r^2

so M=(k)r^2

and when r=2, m=14

so 14=(k)(2)^2

k=14/4 =7/2

so when r=12

m= (7/2)(12)^2 =(7/2)(144) = 504

line w passes through point (-6,-7) and has a slope 1/2. what is the equation for the line in point-slope form?

Elena L [17]

Answer:

y + 7 = $\frac{1}{2}$ (x + 6)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = $\frac{1}{2}$ and (a, b ) = (- 6, - 7 ) , then

y - (- 7) = $\frac{1}{2}$ (x - (- 6) ) , that is

y + 7 = $\frac{1}{2}$ (x + 6)
