23 = 24 - 1, so 23 = -1 = 7 mod 8
Answer:
The answer to your question is: D = non of the above
Step-by-step explanation:
Data
-4x - 4y = -5 (I)
x - 2y = 1 (II)
Process
Find the slopes of both lines
(I) -4x - 4y = -5
-4y = 4x + 5
y = 4/-4 x + 5/-4
y = - x + 5/4
(II) x - 2y = 1
- 2y = - x + 1
y = -1/-2 x + 1/-2
y = 1/2 x - 1/2
The slopes are different slope 1 = -1 and slope 2 = 1/2, so there is no relation between the lines.
Applying the tangent ratio, the distance from A to C across the gorge, is: 60.6 ft.
<h3>What is Tangent Ratio?</h3>
The tangent ratio for solving a right triangle is given as, tan ∅ = opposite/adjacent.
Given the following:
- ∅ = 25°
- Adjacent length = 130 ft
- Opposite length = AC
Apply the tangent ratio:
tan 25 = AC/130
AC = (130)(tan 25)
AC = 60.6 ft

i'm doing cross-multiplication for this problem:
multiply 18 · 12, which is 216
divide 216 ÷ 10, which is 21.6
, is the final answer
