Answer:
They are perpendicular because they have slopes that are opposite reciprocals of −2 and one half.
Step-by-step explanation:
This is because x = -2 and half of -2 is 1
when we use CD line and x2 we find 8x+4y=16 when added to 2x -4y=8 would equal 10x+4y = 2 1/2 xy = 16
When we use for AB line we see they are perpendicular 2 1/2 x 2 = 5 -4y = 8 shows y to be -2 and the 1/2 line leaves -2 1/2 and x also is 2 1/2.
Answer:
3
Step-by-step explanation:
23=5x-4
Add 4 to both sides
27=9x
Divide 9 To both sides
27/9 9x/9
x=3
Answer:
24 π square inches
Step-by-step explanation:
The area of a circule is give by the formula A = π r²
Since we have a angle of 60 degrees, that represent 1/6th of the whole area (60 / 360 degrees).
A circle = π * 12² = 144 π square inches
Area of the portion representing 60 degrees of the circle, can easily be calculated with a cross-multiplication:
x = 144 π / 6 = 24 π square inches
<h2>
Answer:</h2>
The answer is D 62°
<h2>
Step-by-step explanation:</h2>
Equation:
4x-2=62
Solving for x:
4x-2+2=62+2
4x=64
4x/4=64/4
x=16
Plug 16 into the equation to see if the answer is correct:
4•16-2=62
4•16=64
64-2=62°
