17. The owner of an organic fruit stand also sells nuts. She wants to mix cashews worth $5.50 per pound with peanuts worth
exis [7]

Answer:

E

Step-by-step explanation:

Let's let c denote the amount of cashews and let's let p denote the amount of peanuts.

So, the owner wants to mix cashews worth $5.50 per pound with peanuts worth $2.30 per pound to get a 1/2 pound mixture that is worth $2.80 per pound.

In other words, the total pounds as an equation is:

c+p=0.5

Also, the price would be:

5.5c+2.3p=(p+c)2.8

Since we mixed the peanuts and cashews, our sum would be 2.8(p+c).

And we already determined that p+c is 0.5. Thus, substitute:

5.5c+2.3p=(0.5)(2.8)

Simplify:

5.5c+2.3p=1.4

Now, we can solve the system of equations. Isolate a variable from the very first equation:

c+p=0.5

Subtract p from both sides:

c=0.5-p

Now, substitute this into the equation earlier:

5.5c+2.3p=1.4\\5.5(0.5-p)+2.3p=1.4

Distribute:

2.75-5.5p+2.3p=1.4

Combine like terms:

2.75-3.2p=1.4

Subtract both sides by 2.75:

-3.2p=-1.35

Divide everything by -3.2:

p=0.412875

Now, find c:

p+c=.5

Substitute:

c+0.421875=.5

Subtract:

c=0.078125

Thus, the owner would need 0.08 pounds of cashews and 0.42 pounds of peanuts.

Our answer is E.

F(x)=bx^2+32 For the function f defined above, b is a constant and f(2)=40. What is the value of f(-2)?
zhuklara [117]

Answer:

f(-2) = 0

Step-by-step explanation:

Given that:

f(x) = bx^2 + 32

f(2) = b(2)^2 + 32

f(2) = 4b + 32

f(2) = 4b = -32

f(2) = b = -32/4

f(2) = b = -8

Thus;

f(-2) = -8(-2)^2 + 32

f(-2) = -8(4) + 32

f(-2) = -32 + 32

f(-2) = 0
