Answer: 13 comic books
Step-by-step explanation:
1st add 18 + 8 which equals 26
2nd subtract 130 - 26 which equals 104
3rd divide 104 / 8 because each comic book was $8

Answer:
If the inequality is < or >, graph the equation as a dotted line. If the inequality is ≤ or ≥, graph the equation as a solid line. This line divides the xy- plane into two regions: a region that satisfies the inequality, and a region that does not.
Answer:
The sum =105
Step-by-step explanation:
It is given that, finite sequence 3, 7, 11, ..., 27.
<u>Points to remember</u>
1). For a finite sequence sum of n term is given by
Sum = n/2[first term + last term]
2). nth term of of an AP
tₙ = a + (n - 1)d
Where a - First term
d - common difference
<u>To find the number of terms in the given sequence</u>
Here a = 3 and d = 7 - 3 = 4
tₙ = a + (n - 1)d
27 = 3 + (n - 1)*4
4(n -1) = 27 - 3 = 24
n - 1 = 24/4 = 6
n = 6 +1 =7
<u>To find the sum</u>
Sum = n/2[first term + last term]
= 7/2[3 + 27]
= 7/2[30] = 7 * 15
= 105
EXAMPLE OF FUNCTIONS:
f(x) = 3x+2
f(x) = ∛(x²-5x+3)
f(x) = ax³+bx²-c
EXAMPLE OF <span>RELATION:
x</span>²+y²=r² (Circle)
x²/a² + y²/b² = 1 (ellipse)
y = √(x+5) - 3 (parabola opening right/left)
