A softball team bought a box of sweatshirts for $240. Each sweatshirt cost $12 to print and will sell for $18. Graph a system of
icang [17]

Answer:

The number of sweatshirts to sell in order to break even is 40

Step-by-step explanation:

Let x be the number of sweatshirts. We are looking for break even, which means profit is 0 here.

And softball team purchased a box for 240$ and for printing it costs 12$ per shirt.

So total cost of sweatshirts = 240+12x

And selling price is 18$ per shirt.

Hence selling price for x shirts = 18x.

Now we need to graph y=18x and y=240+12x first and then look for intersection to find the break even.

From the graph attached,  we can see that both lines are intersecting at x=40.

Hence number of sweatshirts to sell in order to break even is 40.

Denzel can mow 1/8 of his yard every 7 minutes. If he had 40 minutes to mow 3/4 of the yard, will he have enough time
ehidna [41]

Answer:

No.  He is short by 2 minutes

Step-by-step explanation:

Given that Denzel can mow 1/8 of his yard every 7 minutes.

Hence he can mow the full yard in 7(8) = 56 minutes.

Now he has to do 3/4 of his yard and time is 40 minutes

For 3/4 of yard time taken would be = 3/4 (56) = 42 minutes.

If he had 40 minutes to mow 3/4 of the yard, he will not  have enough time  since he is short of time by 2 minutes.

Using the distributive property to find the product (y - 4x)(y ^ 2 + 4y + 16) results in a polynomial of the form y ^ 3 + 4y ^ 2
galben [10]

Answer:

a=16

Step-by-step explanation:

The distributive property states that

a(b+c)=ab+ac

Therefore using the distributive property

(y - 4x)(y ^ 2 + 4y + 16)

=y(y ^ 2 + 4y + 16) - 4x(y ^ 2 + 4y + 16)

Expanding the brackets

y ^ 3 + 4y^2 + 16y - 4xy ^ 2 - 16xy - 64x.....(i)

Comparing with the form

y ^ 3 + 4y ^ 2 + ay - 4x  y ^ 2 - axy - 64x-----(ii)

The coefficient of y in (i) is 16 which corresponds to a and the likewise the coefficient of xy

Therefore, a=16
