Answer:

only the first one...

a "FUNCTION" has a UNIQUE relation between each input and output...

notice the middle one the -2 goes to BOTH th2 10 & -7 that makes it NOT a FUNCTION

Point A is located at (-2, 2), and point M is located at (1,0). If point M is the midpoint of AB, find the location of point B.

bezimeni [28]

Answer:

B. $B = (4,-2)$

Step-by-step explanation:

GIven that $A = (-2, 2)$ and $M = (1, 0)$ , and that point M is the midpoint of AB, the midpoint can be determined as a vectorial sum of A and B. That is:

$M = \frac{1}{2}\cdot A + \frac{1}{2}\cdot B$

The location of B is now determined after algebraic handling:

$\frac{1}{2}\cdot B = M - \frac{1}{2}\cdot A$

$B = 2\cdot M -A$

Then:

$B = 2\cdot (1,0)-(-2,2)$

$B = (2\cdot 1, 2\cdot 0)-(-2,2)$

$B = (2,0) -(-2,2)$

$B = (4,-2)$

Which corresponds to option B.

The perimeter of a rectangular pen is 136 meters. If the length is 5 meters more than twice the width, what are the dimensions o

Sati [7]

Answer: width = 21, length = 47

Step-by-step explanation:

Length (L) = 2w + 5

width (w) = w

Perimeter (P) = 136

P = 2L + 2w

136 = 2(2w + 5) + 2w substituted the given values above

136 = 4w + 10 + 2w distributed 2 on the right side

136 = 6w + 10 added like terms (4w and 2w)

126 = 6w subtracted 10 from both sides

21 = w divided both sides by 6

Length (L) = 2w + 5

= 2(21) + 5

= 42 + 5

= 47

If f(x) = 5x − 3, which expression represents its inverse function?

Drupady [299]

Answer:

$\frac{x+3}{5}$

Step-by-step explanation:

5x - 3 = y then 5x = y + 3 then x = (y + 3)/5

then the inverse function of f is : (x+3)/5
