If f(x) = 2x-1 what is f(4)

1 answer:

8 0

F(7) is your answer because you plug in 4 to the x so 2•4-1 you times 2 and 4, get 8 then 8-1 is 7, have a good day/night!!!

700+a=3944-b=c-80=3000

velikii [3]

Answer:

A = 3244

B = 864

C = 3080

Step-by-step explanation:

700 + a = 3944

-700 -700

a = 3244

3944 - b = c - 80 = 3000

c - 80 = 3000

+80 +80

c = 3080

3944 - b = c ---> 3944 - b = 3080

-3944 -3944

-b = -864 ---> $\frac{-b}{-1} = \frac{-864}{-1}$

Question

Gnoma [55]

Given parameters:

y varies directly as w;

This interpreted implies that as y increases, we increases by a certain factor or amount;

So, y ∝ w

y = kw

where k is the constant of proportionality

Now, given that y = 8 and w = 2

Input in the equation to solve for k;

8 = k x 2

Solving k gives, k = 4

Now to the second part,

if v is directly proportional to w;

v = k w

So v = 4w

The equation that relates v to w is v = 4w

Which products result in a difference of squares or a perfect square trinomial? check all that apply. (5x 3)(5x – 3) (7x 4)(7x 4

Scilla [17]

(7x + 4)(7x + 4) and (x – 9)(x – 9) are Perfect square trinomial. (5x + 3)(5x – 3) and (–3x – 6)(–3x + 6) shows the Difference of squares.

<h3>What is a perfect square?</h3>

A perfect square is a number system that can be expressed as the

square of a given number from the same system.

The following are the answers

(5x + 3)(5x – 3) Difference of squares

(7x + 4)(7x + 4) is a Perfect square trinomial

(2x + 1)(x + 2) has Neither a difference of squares nor a perfect square trinomial.

(4x – 6)(x + 8) has Neither a difference of squares nor a perfect square trinomial.

(x – 9)(x – 9) is Perfect square trinomial

(–3x – 6)(–3x + 6) = $(-3x)^2- ( -6)^2$ Difference of squares.
