He's driving 42mph. 42m/60h=0.7mpm. 12 minutes x 0.7 mile per minute= 8.4 miles.  21-8.4=12.6 miles left .  12.6 x 0.7= 8.86 minutes left or about nine

Solve the system of linear equations using elimination.
N76 [4]

Answer:

C (-2,1)

Step-by-step explanation:

−2x − y = 3 (1)

−9x − y = 17 (2)

(1) y = -2x - 3

(2) y = -9x - 17

-2x - 3 = -9x - 17

7x = -14

x = -2

y = -2(-2) - 3

y = 4 - 3

y = 1

9966 [12]

Answer:

  6

Step-by-step explanation:

The slope (m) can be found using the formula ...

  m = (y2 -y1)/(x2 -x1)

Any pair of points will do. We can use the first two.

  m = (2 -(-10))/(17 -15) = 12/2

  m = 6

The slope of the line is 6.
