A candy store makes a 9-pound mixture of gummy candy, jelly beans, and hard candy. The cost of gummy candy is $2.00 per pound, j
Musya8 [376]

Let

x--------> the amount of gummy candy in pounds

y--------> the amount of jelly beans in pounds

z-------->  the amount of hard candy in pounds

we know that

x+y+z=9 --------> equation 1

2x+3y+3z=23 --------> equation 2  

x=2y --------> equation 3  

Substitute equation 3 in equation 1 and equation 2

[2y]+y+z=9 -----> 3y+z=9 ------> equation 4

2[2y]+3y+3z=23 -----> 7y+3z=23 ------> equation 5  

using a graphing tool ------> Solve the system of equations

see the attached figure

the solution is the point (3,2)

z=3\ pounds\\y=2\ pounds

<u>Find the value of x</u>

x=2y

x=2*2=4\ pounds

therefore

<u>the answer is</u>

the amount of gummy candy is 4\ pounds

the amount of jelly beans is 2\ pounds

the amount of hard candy is 3\ pounds

In this composite function, (f◦g)(x) where f(x)=(X-3) and g(x)=X^2 what is (f◦g)(x) when x=1?
Alekssandra [29.7K]

Answer:

When x = 1, (f◦g)(x) is -2.

Step-by-step explanation:

Composite function:

The composite function of f and g is given by:

(f \circ g)(x) = f(g(x))

In this question:

f(x) = x - 3, g(x) = x^2

Composite function:

The composite function is:

f(g(x)) = f(x^2) = x^2 - 3

At x = 1

(f \circ g)(1) = 1^2 - 3 = 1 - 3 = -2

So

When x = 1, (f◦g)(x) is -2.
