Answer:

x = 9

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 9 when x = - 3

9 = - 3k ( divide both sides by - 3 )

- 3 = k

y = - 3x ← equation of variation

When y = - 27 , then

- 27 = - 3x ( divide both sides by - 3 )

9 = x

John is at a local bait shop; he wants to buy bait for his fishing trip. At the store, they are selling live bait for $12 a poun
galina1969 [7]

Answer:

x\geq3

12x+7y\leq63

y\geq0

Step-by-step explanation:

If we let x be the amount of live bait and y be the amount of natural bait, Then we can come up with the following inequalities;

We are told that John would like to get at least 3 pounds of live bait. At least 3 means 3 or more. Since x represents the amount of live bait, we have;

x\geq3

Moreover,we are informed that;

The store sells live bait for $12 a pound and natural bait for $7 a pound. x pounds of live bait would cost 12x while y pounds of natural bait would cost 7y. The total cost would thus be;

12x + 7y

but John only has a budget of $63. This implies that he can spend $63 at most, thus;

12x+7y\leq63

Finally we can have our last inequality as;

y\geq0

A manufacturer of screened sweatshirts includes a shipping charge of $5.99 on all online orders. Customers also pay 2.5% tax on
ankoles [38]

Answer:

t = 1.025c + 5.99

Step-by-step explanation:

Recall : general for of a linear equation is given by :

y = mx + c

Given the following :

Item cost = c

Shipping charge = $5.99

Tax on purchases = 2.5%

Total cost, t

t = c + tax + shipping cost

Tax on purchase : 2.5% * item cost ; 0.025c

Shipping = $5.99

Hence,

Total cost, t = c + 0.025c + 5.99

t = 1.025c + 5.99
