Answer:

-20

Step-by-step explanation:

-8v-9=7

Add 9 to each side

-8v-9+9=7+9

-8v = 16

Divide by -8

-8v /-8 = 16/-8

v = -2

Now find

7v -6

7(-2) -6

-14 -6

The function f(x)=x−−√ is reflected over the x-axis, translated 4 units down and 5 units to the left, then vertically stretched

Gnesinka [82]

Transformation involves changing the position of a function.

The equation of the new function is: $\mathbf{g(x) = -3\sqrt{x + 5} - 12}$

The function is given as:

$\mathbf{f(x) = \sqrt x}$

The rule of reflection across the x-axis is:

$\mathbf{(x,y) \to (x,-y)}$

So, we have:

$\mathbf{f'(x) = -\sqrt x}$

The rule of translation, <em>4 units down and 5 units left </em>is:

$\mathbf{(x,y) \to ( x + 5,y-4)}$

So, we have:

$\mathbf{f"(x) = -\sqrt{x + 5} - 4}$

The rule of vertical stretch by a factor of # is:

$\mathbf{(x,y) \to (x,3y)}$

So, we have:

$\mathbf{g(x) = 3(-\sqrt{x + 5} - 4)}$

$\mathbf{g(x) = -3\sqrt{x + 5} - 12}$

Hence, the equation of the new function is:

$\mathbf{g(x) = -3\sqrt{x + 5} - 12}$

Rectangle LOSP is shown below. The lengths, in units, of some of the line segments are also shown. Line segments MQ and NR are p

Galina-37 [17]

Answer: c. OSRN

Step-by-step explanation:

Sides of similar shapes are proportional.

For Rectangle LOSP,

Length = LO = 4+6+8 = 18 units

Width = OS= 12 units

Here, $\dfrac{18}{12}=\dfrac{3}{2}$ [proportionality constant]

a. For Rectangle LMQP,

Length = MQ = 12 units

Width = LM = 4 units

Here, $\dfrac{12}{4}=3\neq\dfrac32$

LMQP is not similar to LOSP.

b. Similarly, for LNRP,

Width = LN= 4+6 = 10

length = NR = 12

$\dfrac{12}{10}\neq\dfrac32$

LNRP is not similar to LOSP.

c. For OSRN,

Length = OS = 12

Width = ON = 8

$\dfrac{12}{8}=\dfrac32$

OSRN is similar to LOSP.

d. For MNRQ,

Length= NR = 12

Width = MN = 6

$\dfrac{12}{6}=2\neq\dfrac32$

MNRQ is not similar to LOSP.

Hence, the shape similar to rectangle LOSP is OSRN.
