Answer:
false
Step-by-step explanation:
Let s, m, L represent the number of small, medium, and Large cups of coffee Kyle filled.
s +m +L = 35 . . . . . . . . . . . . . . . served 35 cups
10s +14m +20L = 544 . . . . . . . . using 544 ounces of coffee
.95s +1.15m +1.50L = 43.60 . . . while collecting $43.60
Solving these 3 linear equations in 3 unknowns by your favorite method, you find
Kyle filled 6 small cups (10 oz)
Kyle filled 16 medium cups (14 oz)
Kyle filled 13 Large cups (20 oz)
_____
Elimination is a reasonable way to start. Subtract 10 times the first equation from the second, and 0.95 times the first equation from the third. Then you have
4m +10L = 194
.2m +.55L = 10.35
Now, you can subtract .05 times the first of these equation from the last to get
.05L = .65
L = 13
Back-substituting gets you the values of the other variables.
Answer:
Step-by-step explanation:
The one-to-one functions g and h are defined as follows.
g={(-7,-6), (-5,4), (4,-7)(7,6)}
h(x)= 3x-14
Find the following.
g-1(4)=
"g-1(4)" just says "Find the pair of coordinates that has 4 for its
y-coordinate, and the answer is its x-coordinate". So we look through those
and find (-5,4) is the only one of those up there that has a 4 for it's y-
coordinate, and so its x-coordinate is -5 and we write:
g-1(4)=-5

Step-by-step explanation:
the elm tree would be 6 meter long
since the first cherry tree and elm is 3 meters apart
so this will be 9-3 is equal to 6
