Answer:
16
Step-by-step explanation:
h(x) = 6 - x
h.h = (6 - x)²
h.h = x² - 12x + 36
h.h(10) = 10² - 12(10) + 36 = 16
Answer:
33 and 42
Step-by-step explanation:
Answer:The trapezoid has 1 line of reflectional symmetry
Step-by-step explanation:
Let d = # of dimes
Let q = # of quarters
45 = d + q
.1d + .25q = 8.40
Then we can use the substitution method and make it so that d = 45 - q.
Then plug in the value for d into the second equation.
.1(45-q)+.25(q)=8.40
4.5-.1q+.25q=8.40
4.5+.15q = 8.40
.15q = 3.90
q = 26
d = 45 - 26 = 19
26 quarters
19 dimes
