Answer:
If x2 + 6x + c = (x + d)2, then d =What value of c makes x2 + 6x + c a perfect square trinomial? c =
Divide the x-term coefficient by 2: 6/2 = 3
Now square 3: 3^2 = 9
c = 9
If x^2 + 6x + c = (x + d)^2, then d =
x^2 + 6x + 9 = (x + 3)^2 = (x + d)^2, so d = 3
Step-by-step explanation:
Answer:
c = +9.
Step-by-step explanation:
x^2 + 6x + c.
Divide 6 by 3 then square it
- so c = 3^2 = 9.
x^2 + 6x + 9 = (x + 3)^2.

A medium pizza cheese pizza a papa johns costs $6.80 plus $0.90 for each topping. The cost of a medium cheese pizza at pizza hut is $7.30 plus $o.65 for each topping. How many toppings need to be added to a large cheese pizza from papa johns and pizza hut in order for the pizzas to cost the same, not including tax?
Answer:
I hope I answered your question!
Step-by-step explanation:
6.80+0.90x=7.30+0.65x (multiply by 100 on both sides)
680+90x=730+65x
50=25x
x=2
Therefore you need to add 2 toppings to each pizza to make them cost the same.

What interval includes all possible values of x, where –3(6 – 2x) ≥ 4x 12? (–[infinity], –3] [–3, [infinity]) (–[infinity], 15] [15, [infinity])
The minimum of x is 15, and the most is infinity, which is the same thing as [15, ∞).
We have given inequality is
–3(6 – 2x) ≥ 4x + 12
What is the meaning of inequality?
The statement of an order relationship greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.
[tex]-3(6 - 2x) \geq 4x + 12\\-18 + 6x \geq 4x + 12\\6x - 4x \geq 12 + 18\\2x \geq 30\\x \geq 15[/tex]
This means that the minimum of x is 15, and the most is infinity, which is the same thing as [15, ∞).

5, one fifth, negative one fifth or 5, How do i solve this?
Answer:
[tex]k = \frac{4}{5} [/tex]
Step-by-step explanation:
We know from the graph
[tex]g(x) = - \frac{1}{5} [/tex]
and
[tex]f(x) = 1[/tex]
using the given equation we can solve
[tex] - \frac{1}{5} = k - 1 \\ [/tex]
subtract 1 from both sides so that k is isolated

Which graph represents the function
Step-by-step explanation:
Your graph will have a vertical asymptote at x = 1, as the denominator x - 1 cannot equal zero. Therefore, f(1) is not posssible. Then, plugging in test values for the function on the left side of the asymptote...
[tex]f(-1) = \frac{2(-1)-1}{-1-1} = \frac{3}{2}\\f(0) = \frac{2(0)-1}{0-1} = 1\\f(2) = \frac{2(2)-1}{2-1} = 3\\f(3) = \frac{2(3)-1}{3-1} = \frac{5}{2}[/tex]
... you will find that your graph needs to include the following points:
[tex](-1, \frac{3}{2})\\(0, 1)\\(2, 3)\\(3, \frac{5}{2})[/tex]
So therefore, your graph must cross through the above points, and may never cross the vertical line x = 1.

Which function in vertex form is equivalent to f(x) = x2 8 – 16x? f(x) = (x – 8)2 – 56 f(x) = (x – 4)2 0 f(x) = (x 8)2 – 72 f(x) = (x 4)2 – 32
The function in vertex form that is equivalent to the equation f(x) = x^2 + 8 - 16x from the given options is given by: Option A: f(x) = (x-8)^2 -56
What is vertex form of a quadratic equation?If a quadratic equation is written in the form
[tex]y=a(x-h)^2 + k[/tex]
then it is called to be in vertex form. It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)
Since it is specified that the options are in vertex form, so let we convert the given equation to vertex form.
The specified equation is: [tex]f(x) = x^2 + 8 - 16x[/tex]
Converting to vertex form:
[tex]f(x) = x^2 + 8 - 16x\\\\f(x) = x^2 -16x + 8\\[/tex]
(let we make terms such that it becomes (a+b)^2 's formula).
[tex]f(x) = x^2 -16x + 8\\f(x) = x^2 -2\times8x + (-8)^2 -(-8)^2 + 8\\f(x) = (x-8)^2 -64 + 8\\f(x) = (x-8)^2 -56[/tex]
Thus, the function in vertex form that is equivalent to the equation f(x) = x^2 + 8 - 16x from the given options is given by: Option A: f(x) = (x-8)^2 -56
