Answer:

250 hamburgers

Step-by-step explanation:

so if there were 50 less cheeseburgers then I would take 50 away from 450 and I would get 400. And then I divided it by 2. And so 200+50 = 250 so 250 hamburgers and 200 cheeseburgers. I hope this helps and I'm not good at explaining. :)

Answer:

  ∠SAP = 85°

Step-by-step explanation:

The whole is the sum of the parts.

  ∠SAX = ∠SAP + ∠PAX

  142° = ∠SAP + 57° . . . . . . . use the given values in the equation

  ∠SAP = 142° -57° . . . . . . . . subtract 57° from both sides

  ∠SAP = 85°

Answer:

x=-2

Step-by-step explanation:

Substitute y=5x+7 into the equation 3x+y=-9

So you will have, 3x+5x+7=-9

3x+5x=8x

8x+7=-9

8x+7-7=-9-7

8x=-16

x=-2

Answer:

The output when x = -9 is f(x) = 187.

Step-by-step explanation:

We are given a function and asked to find the output of that function.

Our standard function is in the form of a quadratic equation.

[tex]ax^2+bx+c=0[/tex]

Let's check for a change in the presentation of the first value in the equation.

[tex]\bold{f(x)} = 2x^2 - 5x - 20\\\\\bold{f(-9)}[/tex]

We see that x becomes -9. We also know that from conventional algebra, we need to make this change throughout the entire equation. Therefore, since we changed the x in f(x), we need to change it in 2x² - 5x - 20 as well.

[tex]f(-9) = 2(-9)^2 - 5(-9) - 20[/tex]

Now, it's time to simplify this function. Let's first simplify the first term of the function: [tex]2(-9)^2[/tex].

Let's follow PEMDAS in order to simplify the term.

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

When using this acronym, make sure that all operations are performed left to right.

We see that -9 is raised to the power of 2, so we square -9. Otherwise, we carry out the following operation.

[tex]-9 \times -9 = 81[/tex]

Then, we see that 2 is multiplied into this value. Therefore, we multiply 81 by 2.

[tex]81 \times 2 = 162[/tex]

Now, we need to subtract the product of 5 and -9.

[tex]5 \times -9 = -45[/tex]

[tex]162 - - 45 = 207[/tex]

Finally, we subtract 20 from this value.

[tex]207 - 20 = 187[/tex]

Therefore, the value of f(-9) is 187.

[tex] \sf f(x) = 2 {x}^{2} - 5x - 20[/tex]

[tex] \sf f( - 9)[/tex]

[tex] : \implies \sf f( - 9) = [2 \times( { - 9}^{2} )]-[ 5 \times - 9] - 20[/tex]

[tex] : \implies \sf f( - 9) = 2 \times 81 + 45 - 20[/tex]

[tex]: \implies \sf f( - 9) = 162 + 45 - 20[/tex]

[tex] : \implies \sf f( - 9) = 207 - 20[/tex]

[tex]: \implies \bf f( - 9) = 187[/tex]

Answer:

rises to the left and rises to the right

Step-by-step explanation:

The end behavior of the graph of f(x) = 3x⁶ + 30x⁵ + 75x⁴ is that it as x → -∞, y → ∞ and as x → -∞, y→ ∞.

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

The degree of the polynomial function is 6, which is even, and the leading coefficient is positive, so the end behavior of the graph is as follows:

As x approaches negative infinity, both the x⁶ and x⁵ terms become very large positive numbers, and so the value of the function f(x) approaches positive infinity.

As x approaches positive infinity, both the x⁶ and x⁵ terms become very large positive numbers, and so the value of the function f(x) also approaches positive infinity.

Therefore, the end behavior of the graph of f(x) is that it as x → -∞, y → ∞ and as x → -∞, y→ ∞.
