Answer:
Range : {11,27,43,59}
Step-by-step explanation:
Given:
f(x) = 4x - 1
Domain : {3,7,11,15}
f(3) = 4(3) -1 = 11
f(7) = 4(7) -1 = 27
f(11) = 4(11) -1 = 43
f(15) = 4(15) -1 = 59
hence Range : {11,27,43,59}
Answer:
x=3.5
Step-by-step explanation:
2.8/4=x/5
cross multiply
2.8(5)=4x
14=4x
x=14÷4
x=3.5
Corresponding angles are 3 and 7, 4 and 8, and 2 and 6.
