7.5 is the answer for this questio
98 divided by 2 equals 49
55 divided by 5 equals 11
F(x) = 2x - 4
f(2 ≤ x) = 2(2 ≤ x) - 4
f(x ≥ 2) = 2(x ≥ 2) - 4
f(x ≥ 2) = 2(x) ≥ 2(2) - 4
f(x ≥ 2) = 2x ≥ 4 - 4
f(x ≥ 2) = 2x ≥ 0
f(x ≥ 2) = x ≥ 0
f(x) = 2x - 4
f(x ≤ 6) = 2(x ≤ 6) - 4
f(x ≤ 6) = 2(x) ≤ 2(6) - 4
f(x ≤ 6) = 2x ≤ 12 - 4
f(x ≤ 6) = 2x ≤ 8
f(x ≤ 6) = x ≤ 4
speed = Distance taken / time travelled
Answer:
a°=79°[alternate angles]
c°=83°[alternate angle]
a° +d°=180°[straight angle]
79°+d°=180
or,d°=180-79
so,d°=101°
Now,
b°+c°=170°[sum of straight angle]
b°+83°=180°
b°=180°-83°
so,b°=97°
