Hello :
<span>the y-intercept of the function f(x) = 2/9x +1/3
when : x = 0
f(0) = 2/9(0)+1/3 = 1/3 </span>
Answer:
Step-by-step explanation:
y = 0.80x + 2.50
a 7 mile ride......x = 7
y = 0.80(7) + 2.50
y = 5.60 + 2.50
y = 8.10 <=== the 7 mile ride cost $ 8.10
the ride cost 13.70.....y = 13.70
13.70 = 0.80x + 2.50
13.70 - 2.50 = 0.80x
11.2 = 0.80x
11.2 / 0.80 = x
14 = x <=== u travel 14 miles
