The number of scented candles ... x
the number of unscented candles ... y
x + y = 28
$16 * x + $10 * y = $400 ... 16 * x + 10 * y = 400
If you would like to know how many scented and how many unscented candles did the shop sell today, you can calculate this using the following steps:
x + y = 28 ... x = 28 - y
16 * x + 10 * y = 400
____________________
16 * (28 - y) + 10 * y = 400
16 * 28 - 16 * y + 10 * y = 400
448 - 400 = 16 * y - 10 * y
48 = 6 * y /6
y = 48 / 6
y = 8
x = 28 - y = 28 - 8 = 20
Result: The candle shop sold 20 scented candles and 8 unscented candles today.
<span>f(x) = x^2 + 1
f(1) = 1</span>^2 + 1 = 2
so 2f(1) = 2(2) = 4
<span>g(x) = 3x + 1
f(4) = 3(4) + 1 = 13
</span>3g(4) = 3(13) = 39
<span> 2f(1) + 3g(4) = 4 + 39 = 43

answer
<span>2. 43</span>
Answer:
-1/3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(2-1)/(-2-1)
m=1/-3
m=-1/3

Answer:
option 4
Step-by-step explanation:
F = 
k is the constant of variation
• if the variables are on the numerator they vary directly
• if the variables are on the denominator they vary inversely
In this case F varies directly with x and y ( variables on numerator ) and inversely with z ( variable on denominator )
