Answer:
3rd option: B(C)= 1.79C +86.03
Step-by-step explanation:
Total bill
= cost of cans(number of cans) +cost of other groceries
Let the cost of other groceries be G, and the cost of cans be X.
Given that number of cans= C,
Total bill= XC +G
If 2 cans were purchased,
2X+G= 89.61 -----(1)
If 5 cans were purchased,
5X +G= 94.98 -----(2)
(2) -(1):
(5X +G) -(2X +G)= 94.98 -89.61
5X +G -2x -G= 5.37
3X= 5.37
X= 5.37 ÷3 <em>(</em><em>÷</em><em>3</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
X= 1.79
Subst. X= 1.79 into (1):
2(1.79) +G= 89.61
3.58 +G= 89.61
G= 89.61 -3.58 <em>(</em><em>-3.58</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
G= 86.03 <em>(</em><em>simplify</em><em>)</em>
Total bill
= XC +G
= 1.79C +86.03
Thus, the function is B(C)= 1.79C +86.03.
Answer:
16
Step-by-step explanation:
-23, -20, -16, -10, -1, -1, 0, 0, 7, 10, 10, 11, 15, 16, 16, 17, 17, 17, 17, 19, 19, 22, 22, 24, 25, 25, 29, 35
Answer:
6 (v-3)^2
Step-by-step explanation:
6v^2–36v+54
Factor out a 6
6(v^2–6v+9)
Then factor inside the parentheses
What 2 numbers multiply to 9 and add to -6
-3*-3 =9 -3+-3 = -6
6( v-3)(v-3)
6 (v-3)^2
Answer:
B and D
Step-by-step explanation:
Geometric sequences and series. A geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio, r.
an = ar^(n-1)
d) 1/3, 2/3, 4/3, 8/3, 16/3, . . . .
1/3 * 2 = 2/3
2/3 * 2 = 4/3
4/3 * 2 = 8/3
where r = 2, constant multiplier is 2. //Answer
b) 320, 80, 20, 5, 1.25, . . . . .
320 * 1/4 = 80
80 * 1/4 = 20
20 * 1/4 = 5
r = 1/4 //Answer
Answer: B and D
//Hope this helps.
