Answer:

D

18y = 306

y = 25 - x

Step-by-step explanation:

y is the number of 18-inch containers.

1 18-inch container occupies 18 inches

y number of 18-inch containers occupy 18y inches.

We are told that  the 18-inch containers occupy 306 inches.

The gives us one equation:

18y = 306    Equation 1

There are 25 containers altogether. x number of them are 12 inches. y number of them are 18 inches. This give us the second equation.

x + y = 25

Now we solve the second equation for y.

y = 25 - x    Equation 2

Put Equations 1 and 2 together, and you have a system of equations.

18y = 306

y = 25 - x

Answer:

D

18y = 306

y = 25 - x

Could you please help with this question for domain, range, and end behavior? I started it, but I think I'm doing it wrong.
Tanzania [10]

It looks like you have the domain confused for the range! You can think of the domain as the set of all "inputs" for a function (all of the x values which are allowed). In the given function, we have no explicit restrictions on the domain, and no situations like division by 0 or taking the square root of a negative number that would otherwise put limits on it, so our domain would simply be the set of all real numbers, R. Inequality notation doesn't really use ∞, so you could just put an R to represent the set. In set notation, we'd write

\{x\in\re\mathbb{R}\}

and in interval notation,

(-\infty,\infty)

The <em>range</em>, on the other hand, is the set of all possible <em>outputs</em> of a function - here, it's the set of all values f(x) can be. In the case of quadratic equations (equations with an x² term), there will always be some minimum or maximum value limiting the range. Here, we see on the graph that the maximum value for f(x) is 3. The range of the function then includes all values less than or equal to 3. As in inequality, we can say that

f(x)\leq3,

in set notation:

\{f(x)\in\mathbb{R}\ |\ f(x)\leq3\}

(this just means "f(x) is a real number less than or equal to 3")

and in interval notation:

(-\infty,3]

Suppose a medium pizza at Vincent’s costs $6.75 plus $0.75 for each topping, and the cost of a medium pizza at Original Italian
lapo4ka [179]

Answer:

12 toppings

Step-by-step explanation:

There's a 60 cent difference in the base price, and the price of toppings is a 5 cent difference, so it would take 60/5 or 12 toppings to make up the difference.   r, you can make a chart.  Or you can do algebra and solve an equation:

6.75 + .75 x = 6.15 + .8x  where x is the number of toppings.  Subtract 6.15 from both sides.

.60 + .75x = .8 x     Subtract .75x from both sides

.60 = .05x         Divide both sides by .05

What is an equation in point line slope form of the line that passes through the point (4,-1) and had slope 6
zimovet [89]

Answer:

y+1=6(x-4)

This is if you want it in point slope for,.

Step-by-step explanation:

Then, if you simplify it.

y+1=6x-24

y=6x-25

Now, it is in slope intercept form.
