Shiloh has to earn at least $200 to meet her fundraising goal. She has only 100 cakes that she plans to sell at 5 dollars each. Which inequality shows the number of cakes, x, Shiloh can sell to meet her goal?

Answers

Answer:

40 \leq x \leq 100

Step-by-step explanation:

Cost of 1 cake = $5

Let x be the no. of cakes

So, Cost of x cakes = 5x

Since we are given that Shiloh has to earn at least $200

So, 5x\geq 200

x\geq 40

So, the no. of the cakes should be sold more than or equal to 40

We are also given that She has only 100 cakes

So, the maximum number of cakes she can sold is 100 i.e.x\leq 100

So, Inequality becomes : 40 \leq x \leq 100

Hence inequality shows the number of cakes, x, Shiloh can sell to meet her goal is 40 \leq x \leq 100
she will only have to sell 40 cakes to earn $200

Step-by-step explanation:

Factor completely 14bx2 − 7x3 − 4b + 2x.(2b + x)(7x2 + 2)

(2b − x)(7x2 − 2)

(2b + x)(7x2 − 2)

Answer:

(2b-x)(7x^2-2)

Step-by-step explanation:

We have to factor the expression 14bx^2-7x^3-4b+2x

We apply the method of grouping to factor it.

Make groups

(14bx^2-7x^3)+(-4b+2x)

Take GCF

7x^2(2b-x)-2(2b+x)

Finally, factored out the common factor

(2b-x)(7x^2-2)

The factored form of the given expression is

(2b-x)(7x^2-2)
hello,

14bx²-7x^3-4b+2x= -7x^3+14bx²+2x-4b
=-7x²(x-2)+2(x-2b)
=(x-2b)(-7x²+2)
=(2b-x)(7x²-2)

If f(x) is the total cost, in dollars, of x candies, which of the following statements best describes the meaning of f(2) = 6? A. The total cost of 2 candies is $6.00./ B. The total cost of 6 candies is $2.00. / C. The total cost of 2 candies is $3.00. / D.The total cost of 3 candies is $2.00.

Answers

Since the cost is a function of the total number of candies (x), therefore the equation relates the total cost per amount of candies.

Since we have 2 candies therefore the correct statement should be that the total cost of 2 candies is $6.00

this statement is letter A of the given choices. 

Answer:

The total cost of 6 candies is $2.00.

Step-by-step explanation:

Given :  f(x) is the total cost, in dollars, of x candies,

To Find: Which of the following statements best describes the meaning of f(2) = 6?

Solution:

We are given f(2)=6

Since f(x) is the total cost, in dollars, of x candies.

So, 6 is the total cost of 2 candies.

Thus the total cost of 2 candies is $6.

Hence Option A is true.

The total cost of 6 candies is $2.00.
