Answer:
f(-3) = 21
g(3) = 69
Step-by-step explanation:
We have been given the following functions;
f(x) = –6x + 3
g(x) = 3x + 21x–3.
To find f(-3) , we simply substitute x = -3 in the function of f(x);
f(-3) = -6(-3) + 3
= 21
To find g(3) , substitute x = 3 in the function of g(x);
g(3) = 3(3) +21(3) - 3
= 69
Answer:
Q1. 1050 miles
Q2. 1h 30m
Step-by-step explanation:
Q1. 1h = 300 miles
3
h = 3.5 × 300 miles
= 1050 miles
Q2. 68km = 1h
102km = 
× 1h
= 1.5h
= 1h 30m
Answer:
4 3/8 yards.
Step-by-step explanation:
2 5/8 = (2*8 + 5)/8 = 21/8.
1 3/4 = (1*4 + 3) / 4 = 7/4.
21/ 8 + 7/4
= 21/8 + (7*2) / (4*2)
= 21/8 + 14/8
= 35/8
= 4 3/8.
