Answer:
Inequality Form: x ≤ 8
Interval Notation: (-∞,8]
Step-by-step explanation:
x + 5 ≤ 13
Subtract 5 on both sides...
13 - 5 = 8
You're left with x ≤ 8
Inequality Form: x ≤ 8
Interval Notation: (-∞,8]
Answer:
2ft
Step-by-step explanation:
5 x 10=50
7 x 12= 84
5+2=7 and 10+2=12
Answer:

Step-by-step explanation:
we know that
<u><em>Combinations</em></u> are a way to calculate the total outcomes of an event where order of the outcomes does not matter.
To calculate combinations, we will use the formula

where
n represents the total number of items
r represents the number of items being chosen at a time.
In this problem

substitute

simplify




First you have to distribute. -3y +12=18. -3y=6. y= -2.
Answer:
Center (4, -13)
Radius = 17
Step-by-step explanation:
Circle equation: 
(h, k) is the center of the circle and the r is the radius.

h = 4, k = -13, r = 17
