Answer: x = -4; x = -1; x = 3
see in this graph, at x = {-4; -1; 3} => y = 0
=> the zeros of the function are -4; -1; 3
Step-by-step explanation:
The correct answer is 0.48405
Answer:
paper clips = $1.85
index cards = $3.95
Step-by-step explanation:
Mark
12 paper clips = x
10 index cards = y
$61.70 total
Janice
15 paper clips = x
7 index cards = y
$55.40 total
12x + 10y = 61.70
15x + 7y = 55.40
*** you want to cancel out one of the letters
(12x + 10y = 61.70) * -7
(15x + 7y = 55.40) * 10
-84x -70y = -431.9
150x + 70y = 554.0
150x + 70y = 554.0
-84x -70y = -431.9
66x + 0 = 122.1
66x = 122.1
x = 122.1 ÷ 66
x = 1.85
plug it back in
15(1.85) + 7y = 55.40
27.75 + 7y = 55.40
7y = 55.40 - 27.75
7y = 27.65
y = 27.65 ÷ 7
y = 3.95
We are given the data that in each box of cupcakes the capacity is a maximum of 24. There are 300 cupcakes required. Hence the number of boxes needed is 300 cupacakes/ 24 cupcakes/ box. The answer is equals to 12. 5. Since there is no such thing as 0.5 box, the answer is rounded up to C. 13
