Answer:
-3
Step-by-step explanation:
v/71 = -3/71.
1. Isolate the variable by multiplying both by 71/1. This makes the left side of the equation equal to 1v, which is the same as v. The right side can now be cancelled, because 71 in the denominator of -3/71 and the 71/1 can make it -3, now. So your v = -3.
The answer is > 1 because if the scale factor is greater than 1 than the image will be an enlargement.
Hope this helps :)
Answer:
Step-by-step explanation:
4/x + 4/(x²-9) = 3/(x - 3)
4 / x + 4 / [( x - 3) ( x + 3 )] = 3 / ( x - 3 ) / * x ( x - 3 ) ( x + 3 )
Restrictions : x ≠ 0, x ≠ - 3 , x ≠ 3;
4 ( x + 3 ) ( x - 3 ) + 4 x = 3 x ( x + 3 )
4 ( x² - 9 ) + 4 x = 3 x² + 9 x
4 x² - 36 + 4 x - 3 x² - 9 x = 0
x² - 5 x - 36 = 0
x² - 9 x + 4 x - 36 = 0
x ( x - 9 ) + 4 ( x - 9 ) = 0
( x - 9 ) ( x + 4 ) = 0
x - 9 = 0, or : x + 4 = 0
Answer:
x = 9, x = - 4
The correct answer is option 1. Because when he is 5, he is in division one, that circle is filled in (that means it’s inclusive). When he turns seven, though, he moves up to division two. That means that it’s inclusive when he turns seven, but not when he turns five. So, it’s an inclusive closed circle on the left, and an exclusive open circle on the right. Lmk if u need more clarity!
Answer:
Yep.
Step-by-step explanation:
It's the equation of the circle of radius 4 units.
