If f(x)=2x and g(x) = x-4 what is the value of g(f(3)) ?

Mathematics

Dahasolnce [82]2 years ago

Answer:

The value of g(f(3)) = 2

Step-by-step explanation:

We are given:

f(x)=2x

g(x) = x-4

And we need to find g(f(3))

First we need to find g(f(x))

by putting the value of f(x) into g(x) i.e put x = 2x

g(x)=x-4\\g(f(x))=2x-4

Now, we need to find g(f(3)) by putting x = 3 in g(f(x))

g(f(x))=2x-4\\Put\: x=3\\g(f(3))=2(3)-4\\g(f(3))=6-4\\g(f(3))=2

So, the value of g(f(3)) = 2

Weiming, Joyce and Siti divide cookies to sell in a ratio of 5: 12: 9. After Weiming sold 28 cookies, the ratio becomes 1: 8: 6.
Strike441 [17]

Answer:

216 cookies

Step-by-step explanation:

From the question,

Let the total cookies in the first place be x cookies.

Their ratio = 5:12:9

Total  = 5+12+9 = 26.

Weiming share = (5/26)x = 5x/26

If weiming sold 28 cookies

⇒ (5x/26)-28

⇒ (5x-728)/28

Hence Weiming new share = (5x-728)/28 cookies

The new ratio is 1:8:6

The total cookies becomes = x-28

Therefore,

(1/15)(x-28) = (5x-728)/28

(x-28)/15 = (5x-728)/28

Crossmultiply

28(x-28) = 15(5x-728)

28x-784 = 75x-10920

Collect like terms

28x-75x = -10920+784

-47x = -10136

x = -10136/-47

x = 215.7

x ≈ 216 cookies

Which value must be added to the expression x2 + x to make it a perfect-square trinomial? One-fourth One-half 1 4
SVEN [57.7K]

Answer:

\frac{1}{4}

Step-by-step explanation:

Given

x² + x

To complete the square

add ( half the coefficient of the x- term )² to x² + x

x² + 2(\frac{1}{2} )x + (\frac{1}{2} )² = x² + x + \frac{1}{4}

= (x + \frac{1}{2} )² ← perfect square
