Use slopes to determine if the lines -7x-2y=-8 and 2x+7y=-3 are perpendicular or not

Mathematics
1 answer:
Flauer [41]3 years ago
5 0

Answer:

Since slopes of both lines are not negative reciprocals. Therefore Lines are not perpendicular to each other

Step-by-step explanation:

Slope of -7x-2y=-8 is -7/2

Slope of 2x+7y=-3 is -2/7

For perpendicular lines slopes are negative reciprocals of each other

Find x. (Use pic for more info)
V125BC [204]

Answer:

x=75

Step-by-step explanation:

Hey There!

If you didn't know the exterior angle of a triangle is equal to the sum of the opposite interior angles of a triangle

So essentially what I'm saying is that

2x-5=70+x

step 1 add 5 to each side

-5+5 cancels out

70+5=75

now we have

2x=70+x

step 2 subtract x from each side

x-x cancels out

2x-x=x

we're left with

x=75

A kite is flying 12 ft off the ground. Its line is pulled taut and casts an 8 -ft shadow. Find the length of the line. If necess
LenKa [72]
Answer

14.4 ft~

Step-by-step explanation

A kite is flying 12 feet off the ground, therefore the height is 12 (assuming the line is tied to the ground if a person is holding the line then the height would be less)

Assuming the sun is positioned in such a way that the shadow represents a horizontal distance. Horizontal distance of shadow = 8

Use Pythagoras Theorem

Where a^2 + b^2 = c^2

8^2 + 12^2 = 208

Square root 208 = 14.4~
