Answer:
$17.2
Step-by-step explanation:
120 + 16*100 = 120 + 1600 = 1720
The member pays $1720 annually for 100 classes and membership fee combined.
1720/100 = 17.2
The student pays $17.2 per class on average.
Answer: ITS 100% D.)12
Step-by-step explanation:
2x * 12 = 24 = 36
3x * 13 = 36
therefore, x= 12
hope this was helpful :D
brainliest plz?
To solve, you make a systems of equation:
x+(x+3)=25, the x representing the number of pigs. Since there is no multiplication and following the order of operations, you add the x’s to get 2x+3=25. Then, you subtract 3 from both sides to get 2x=22, then divide by 2 on both sides to isolate the variable. Therefore, x=11 and Mary is taking care of 11 pigs.
Answer: C
Explanation: Let's find each equation without any inequalities first. We have a dotted line at y = 1, so we can already remove A and B. Now, a dotted line represents exclusivity and hence; it should not include the = sign.
Thus, by elimination, the answer must be C.
Step-by-step explanation:
According to factor theorem, if x − c is a factor of f(x), then f(c) = 0.
Conversely, if f(c) = 0, then x −c is a factor of f(x).
a) If x − 3 is a factor of f(x), then f(3) will be 0.
f(3) = 4(3)³ − 12(3)² + 2(3) − 6
f(3) = 0
b) Having shown that x − 3 is a factor of f(x), we can use grouping or long division to factor f(x):
f(x) = 4x³ − 12x² + 2x − 6
f(x) = 4x² (x − 3) + 2 (x − 3)
f(x) = (4x² + 2) (x − 3)
Since 4x² + 2 has only imaginary zeros, 3 is the only real root.
