Answer:
x = -4
Step-by-step explanation:
Step 1: Subtract 1/2x on both sides
-1/4x - 1/8 = 7/8
Step 2: Add 1/8 on both sides
-1/4x = 1
Step 3: Divide both sides by -1/4
x = -4
Answer:
D. (-2, 1).
Step-by-step explanation:
y = 3x + 7
y = -2x - 3
AS the expressions on the right are both equal to y:
3x + 7 = -2x - 3
3x + 2x = -3 - 7
5x = -10
x = -2
Plug this into the first equation:
y = 3(-2) + 7
y = 1.
Answer:
799 feet
Step-by-step explanation:
We solve using the Trigonometric function of Tangent.
tan theta = Opposite /Adjacent
From the above question, we have the height of the surveyor = 5.5 feet
theta = Angle of elevation = 65°
Adjacent = 370 feet
Let Opposite = height + height of spider rock
tan 65° = h - 5.5 /370 feet
Cross Multiply
tan 65° × 370 feet = h - 5.5
793.46756059 feet = h - 5.5
h = 793.46756059 feet + 5.5
h = 798.96756059 feet
Approximately = 799 feet
The height of the Spider rock = 799 feet
I got it to be .3125 or 31%. just convert that to a fraction and you got it. sorry I forget how to put that decimal into a fraction it's been a year:)
