The answer is B, f(x) = 4x + 4.
If you substitute 2 for x, the resulting answer will be 12, therefore it is correct.

If f(X+4) =3x+4 , then find the value of f(4) <br>please explain it clearly .

Paul [167]

$\\ \sf\longmapsto f(x+4)=3x+4$

$\\ \sf\longmapsto f(x)=3x+4-4$

$\\ \sf\longmapsto f(x)=3x$

Now

$\\ \sf\longmapsto f(4)$

$\\ \sf\longmapsto 3(4)$

$\\ \sf\longmapsto 12$

Given : The number of kinds of fruits = 5

The number of kinds of herbal teas = 3

The number of kinds of flavors of wrap sandwich = 6

Then by using the fundamental principal of counting, the number of possible snack are there will be :_

$5\times3\times6= 90$

Therefore, the number of possible snacks = 90

190 = 200^b, make b the subject

MArishka [77]

Answer:

b = $\frac{ln190}{ln200}$

Step-by-step explanation:

Using the rule of logarithms

log $x^{n}$ ⇔ nlogx

Given

190 = $200^{b}$ ( take the natural log ln of both sides )

ln190 = ln $200^{b}$ = bln200 ( divide both sides by ln200 )

$\frac{ln190}{ln200}$ = b

Answer:

Slope AB = -3/2

R = (4, -7)

Step-by-step explanation:

AB (-6 , 8) and (-2 , 2)

Slope AB = (8 - 2) /(-6 + 2) = 6/-4 = -3/2

Triangle QRS , QR is half of AB, same orientation and given Q (2 , -4) so R = (4, -7)

The perimeter of a parallelogram is 72 meters. The width of the parallelogram is 4 meters less than its length. Find the length

mafiozo [28]

Perimeter of a parallelogram = 2(l + w). But w = l - 4
Therefore, 72 = 2(l + l - 4) = 2(2l - 4) = 4l - 8
4l = 72 + 8 = 80
l = 80/4 = 20
w = 20 - 4 = 16

Therefore, length = 20 meters and width = 16 meters
