Describe the types of transformation given by each parameter in g(x) = -4f(-x + 2) + 6

forsale [732]

Step-by-step explanation:

Starting with f(x)

f(x)

f(-x) ...... reflection in the y - axis

f(-x+2) ..... horizontal translation by 2 units in the negative x-direction

f(-x+2) + 6 ...... vertical translation by 6 units in the positive y-direction

4f(-x+2) + 6 ..... scaling (or dilation) by a factor of 4

-4f(-x+2) + 6 ..... reflection in the x-axis

Yuri’s sister Karina is 12 years old. In the equation below, y represents Yuri’s age in years.

OLga [1]

In the given equation above, it can be deduced that 2 subtracted from 3 times Yuri's age is equal to the age of Karina which was given to be twelve. This statement is similar to that which is given in the choice number four. Thus, the answer is D.

The ratio of the number of Victor’s tools to the number of Ilya’s tools is 5:2. Victor has 42 more tools than Ilya. How many too

irga5000 [103]

Answer:

Victor gives 28 tools to IIya.

Step-by-step explanation:

Consider the provided information

The ratio of the number of Victor’s tools to the number of Ilya’s tools is 5:2

Let V represents the Victor and I represent llya

Therefore,

$\frac{V}{I} = \frac{5}{2}$

It is given that Victor has 42 more tools than Ilya.

$\frac{V}{I} = \frac{5}{2}=\frac{42+I}{I}$

Solve the above equation.

$\frac{5}{2}=\frac{42+I}{I}$

$5I=84+2I$

$3I=84$

$I=28$

Thus, IIya has 28 tools.

Victor has 42 more tools than Ilya. Therefore 42 + 28 = 70.

Victor has 70 tools.

We want to find the number of tools victor needs to give to IIya so that the ratio of the number of Victor's tools to the number of Ilya’s tools will be 3:4

Let Victor gives x tools to IIya. Thus,

$\frac{3}{4}=\frac{70-x}{28+x}$
