Answer:
x=1, y=6. (1, 6).
Step-by-step explanation:
-8x+4y=16
y=5x+1
----------------
-8x+4(5x+1)=16
-8x+20x+4=16
12x+4=16
12x=16-4
12x=12
x=12/12
x=1
y=5(1)+1=5+1=6
Answer:
Perimeter of rectangle added 2 to length:
perimeter of rectangle= length + width + length + width
P = ( l + 2 ) + w + ( l + 2 ) + w
P = 2 ( l + 2 ) + 2 w
P = 4 + 2 l + 2 w
Perimeter of rectangle added 2 to width:
P = l + w + l + w
p = l + ( w + 2) + l + ( w + 2)
p = 2 l + 2 ( w + 2)
p = 2 l + 2 w + 4
345,000 ; 350,00 ; 300,000.
Answer:
YES
Step-by-step explanation:
Any line that is tangent to a circle is always perpendicular to the radius of the circle, forming a right angle at the point of tangency.
Therefore, ∆BAC is a right triangle if it satisfy the pythagorean triple rule which says that c² = b² + a²
Where,
c = the hypotenuse = 30
b = 24
a = 2(9) = 18
Thus:
30² = 24² + 9²
900 = 900 (this is true)
Therefore, line AB is tangent to circle O.
The answer is YES
