mash [69]

Answer:

You could do 5 x 1 = 5

And for fifty, 5 x 10 = 50

Step-by-step explanation:

Standard form is basically a big or small equation of the numbers

standard form is the usual way of writing numbers in decimal notation, i.e. standard form = 876, expanded form = 800 + 70 + 6, written form = eight hundred seventy six

Identify the rule that could possibly describe this set of data.

Elina [12.6K]

option D is the correct option

y= 10- 2x

Now, if we take the first value of x i.e 1

then, y= 10-2(1)

= 10-2 = 8 ---------> this value matches with the given value of y

take,x =2

y=10-2(2) = 10-4 = 6--------->this value matches with the given value of y

taking, x = 3

y= 10-2(3) = 10- 6=4-------->this value matches with the given value of y

Describe the transformation from y= x + 4 to y= .5x + 4 Group of answer choices compresses stretches shifts right 4 shifts left

Nina [5.8K]

Answer:

This type of transformation is a horizontal stretch.

Step-by-step explanation:

Given

$y = x + 4$

$y = .5x + 4$

Required

Determine the type of transformation

The first function can be expressed as:

$f(x) = x + 4$

While the second function is:

$g(x) = f(0.5x)$

Solving f(0.5x), we have to substitute 0.5x for x in $f(x) = x + 4$

$f(0.5x) = 0.5x + 4$

So:

The second function is:

$g(x) = 0.5x + 4$

This type of transformation is a horizontal stretch.

i.e. f(x) stretched to g(x)
