When the slope m is multiplied by -1 in f(x)=mx+b. What type of transformation is used.

It is equivalent to a reflection over the y-axis.

Step-by-step explanation:

We start with the function:

f(x) = m*x + b

where the slope is m.

If we only multiply the slope by -1, the function becomes:

f(x) = -m*x + b

There is a transformation called a reflection over the y-axis.

This works as follows, if we have a function f(x), a reflection over the y-axis is written as:

g(x) = f(-x)

If we apply this to our function, we get:

g(x) = f(-x) = m*(-x) + b

g(x) = -m*x + b

Then we can conclude that:

"When the slope m is multiplied by -1 in f(x)=mx+b, it is equivalent to a reflection over the y-axis"

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
