Answer:

y = In(x) - 5

Step-by-step explanation:

The translation is a geometrical transformation, that changes the location of a figure. In a function, the independent term exerts a role in the translation of the graph.

Algebraically, to translate the function by shifting down 5 units. We have to insert in the domain a value that will return to zero and add negative 5 units.

To satisfy this condition, all that's left is the first and the last option.

Let's test.

y = In(x-5)

y=log_{e} (x-5)\\ y=ln (1-5)\\ y=ln(-4)\\ y=

There is no logarithm < 0

y = In(x) - 5

lnx=log_{e} x\\ y=log_{e}(x)-5\\ y=log_{e}(1)-5\\ y=0-5\\ y=-5

So (1,-5) this is the first point after the curve leaves the y axis

Geometrically, Check the graph below.

Y=ln(x)-5 because when shifting down you look at the number outside parenthesis

Serggg [28]

Answer:

y= 2/3x -1

Step-by-step explanation:

Ok so basically we want to put it in the form y=mx+b where m is 2/3 and passes through the point (9,5). So sub in the x and y of the point in brackets into the equation. 5= 2/3(9) + b and solve for b so b = -1. Therefore the equation is y=2/3x -1

In a certain year, there were 88 female officials in Congress, which is comprised of the House of Representatives and the Senate
Ainat [17]

Answer:

  • 71 in House of Representatives
  • 17 in Senate

Step-by-step explanation:

Let h and s represent the numbers in the House and Senate, respectively. Then we have ...

  h + s = 88

  h - s = 54

Subtracting the second equation from the first gives ...

  (h +s) -(h -s) = (88) -(54)

  2s = 34 . . . . . simplify

  s = 17 . . . . . . . divide by 2

  h = 88 -17 = 71 . . . . find the other value using the sum equation

There were 71 females in the House of Representatives, and 17 females in the Senate.
