Lea left Sarawong's house and traveled toward the town hall at an average speed
of 70 km/h. Sometime later Jacob left
traveling in the opposite direction with an
average speed of 70 km/h. After Lea had
traveled for two hours they were 280 km
apart. Find the number of hours Jacob
traveled.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
