A fruit stand has to decide what to charge for their produce. They decide to charge $5.30 for 1 apple and 1 orange. They also plan to charge $14 for 2 apples and 2 oranges. We put this information into a system of linear equations.Can we find a unique price for an apple and an orange?

Answers

Answer 1

Answer:

Answer:

We cannot find a solution to the system of equations.

a+b = 5.30

2a + 2b = 14

Step-by-step explanation:

Let a = the price of an apple

let b = price of an orange

a+b = 5.30

2a + 2b = 14

Multiply the first equation by 2

2a+ 2b = 10.60

Subtract the second equation

2a+2b = 10.60

-2a+2b = 14

---------------------------

0 = -3.40

This is never true so there is no solution

Solve the equation 4 1/5+b= 9 3/5 b=---

and if you could work it out and show me that would help a lot.

Answers

4 1/5 + b = 9 3/5

4 1/5 - 4 1/5 + b = 9 3/5 - 4 1/5
(taking the same amount from each side to keep it balanced)

0 + b = 5 2/5
(subtracting 4 1/5 from each side)

b = 5 2/5

4 1/5+b=9 3/5
convert to improper fraction
21/5+b=48/5
since they both have the same denominators,you can subtract the numerators
b= 48/5-21/5
b=27/5= 5 2/5

hope this helps

Answer:

$\cot x$

Step-by-step explanation:

It is required to find the parent function of the given graph.

Since, we know that,

Range of the functions, $\sin x$ and $\cos x$ is [-1,1].

So, the given graph cannot be obtained from the functions $\sin x$ and $\cos x$ .

Also, we know,

Range of the functions, $\csc x$ and $\sec x$ is $(-\infty,-1]\cup [1,\infty)$ .

Thus, the given graph cannot be obtained from the functions $\csc x$ and $\sec x$ .

So, we are left with the functions, $\tan x$ and $\cot x$ .

Moreover, as $\tan 0=0$

But, in the graph, function is going to infinity when x= 0.

Thus, the graph cannot be obtained from $\tan x$ .

Hence, the parent function is $\cot x$ .
