Answer:

y = -3x + 20

Step-by-step explanation:

All you need to do is plug the (x,y) coordinates of (5,5) into the slope intercept formula to find the value of b to make the equations. Also, M is the value of the slope which is given to you as the value of -3.

1. The first 5 in the coordinate is the value Y and the second 5 in the coordinate is the value of Y. Substitute these numbers into the formula and solve.

5 = -3(5) +b (multiply -3 * 5)

5 = -15 + b (add 15 to both sides)

20 = b (this is the value of b)

2. Now just combine everything to form the equation

y = -3x + 20

Asanji left the science museum and drove toward the lake at an average speed of 45 km/h. Sometime later Huong left driving in th
Cloud [144]

Answer:

Asanji drove for 5 hours before Huong caught up

Step-by-step explanation:

Let the time for which Asanji drove alone is "X" hours

Asanji and Huong met after three hours of driving of Huong.

Total time for which Asanji drove = X+3 hours

Thus, distance travelled by Asanji in X+3 hours is equal to distance travelled by Huong in 3 hours

45 ( X+3) = 75 (3)\\

On solving the above equation, we get -

45 X + (45 *3) = 75 *3\\45 X = (75-45)*3\\45 X = 30 *3 \\X = \frac{30 *3}{45} \\X = 2

Asanji drove for 3 + 2 = 5 hours before Huong caught up
