Answer:
C
Step-by-step explanation:
law of communicative multiplication
A = 4000(1 + [0.065 * 5])
A = $5300
4a + 9b + 0c = 8 ⇒ 4a + 9b + 0c = 8
8a + 0b + 6c = -1 ⇒<u> 8a + 0b + 6c = -1</u>
0a + 6b + 6c = -1 12a + 9b + 6c = 7
12a + 9b + 6c = 7 ⇒ 24a + 18b + 12c = 14
4a + 9b + 0c = 8 8a + 6b + 12c = 0 ⇒ <u>24a + 18b + 36c = 0</u>
8a + 0b + 6c = -1 ⇒ 8a + 0b + 6c = -1 <u>-24c</u> = <u>14</u>
0a + 6b + 6c = -1 ⇒ <u>0a + 6b + 6c = -1</u> -24 -24
8a + 6b + 12c = 0 c = ⁷/₁₂
6b + 6(⁷/₁₂) = -1
6b + 3¹/₂ = -1
<u> - 3¹/₂ - 3¹/₂</u><u>
</u> <u>6b</u> = <u>-4¹/₂
</u> 6 6<u>
</u> b = ³/₄
4a + 9(³/₄) = 8
4a + 6³/₄ = 8
<u> - 6³/₄ - 6³/₄
</u> <u>4a</u> = <u>1¹/₄</u>
4 4
a = ⁵/₁₆
(a, b, c) = (⁵/₁₆, ³/₄, ⁷/₁₂)
Anser is 111.1
To find The perimeter you just add all the sides together 10.9+10.9+40.3+40.3 equals 111.1
Answer:
The parallel line would be y = 1 and the perpendicular line would be x = 3.
Step-by-step explanation:
In order to find a line parallel to y = 5, we must first note that y = 5 is a horizontal line. This means to be parallel, the line must also be horizontal. All horizontal lines are written in the form of y = (just a number). Since we can see the value of y in the ordered pair as 1, we know the equation is y = 1.
The exact opposite logic can be used to find the perpendicular line. Since the first line is horizontal, the next one will be vertical, which are written as x = (a number). We again look to the ordered pair to determine the number and write the equation as x = 3
