Oliver has d dimes and q quarters. he has at least $4 worth of coins altogether. write
this situation as an inequality.

Step-by-step explanation:

d = dimes and q = quarters

0.10d + 0.25q > = 4 (thats greater then or equal to)

Good evening ,

10d + 25q ≥ 400.

Step-by-step explanation:

d dimes = 10×d cents

q quarters = 25×q cents

$4 = 400 cents

He has at least $4 worth of coins altogether Means 10d + 25q ≥ 400.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
