A CAR JOURNEY OF 380 KM LASTS 4 HOURS. PART OF THIS IS ON A MOTORWAY AT AN AVERAGE SPEED OF 110KM H/H, THE REST ON COUNTRY ROADS AT AN AVERAGE SPEED OF 70KM/H. CAN SOMEONE WRITE THIS INFORMATION AS A PAIR OF SIMULTANEOUS EQUATIONS?

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
