(-2,4) on cordinate plane

1 answer:

8 0

The coordinate -2, 4 implies -2 is the value on the x or horizontal axis and 4 is the value on the y or vertical axis.

<h3>What is a coordinate plane?</h3>

This a plane used for graphs or points that is based on a vertical axis (y) and a horizontal axis (x).

<h3>How does -2,4 look on a coordinate plate?</h3>

The first number, -2 indicates the value in x or the horizontal axis, while the second number 4 indicates the position on y or the vertical axis. You can see this in the imaged attached (red dot).

Answer:

12.25 (or -18.75)

Step-by-step explanation:

If you pay attention to the square of a binomial, ...

(x -a)² = x² -2ax +a²

You see that the constant (a²) is the square of half the x-coefficient. That is, the x-coefficient is -2a, half that is -a, and the square of that is (-a)² = a².

In your equation, the x-coefficient is -7, half that is -3.5, and the square of that is 3.5² = 12.25.

So, you can think of this ambiguous question in a couple of ways.

<u>Concern is only with the x-terms</u>:

x² -7x +31 = (x² -7x +12.25) +31 = 12.25 . . . . . . add 12.25 to both sides

(x -3.5)² +31 = 12.25 . . . . write the x-terms as a square

<u>Concern with the equation overall</u>:

You want the end result to have the x-terms in the form of the square ...

(x -3.5)² = x -7x +12.25

The left side of the equation can be put in that form by adding -18.75 to both sides;

x² -7x +31 -18.75 = -18.75 . . . . . . add -18.75 to both sides

x² -7x +12.25 = -18.75 . . . . . . . . . simplify

(x -3.5)² = -18.75 . . . . . . write the left side as a square

The short of it is that we're not sure what the question is asking for exactly. The "help video" would probably clarify the intent. Most likely, you're concerned with adding the square of half the x-coefficient, 12.25.

Answer:

9 1/4

Step-by-step explanation:

1/2 = 2/4

11 1/2 = 11 2/4

11 2/4 - 2 1/4

11 - 2 = 9

2/4 - 1/4 = 1/4

A patient weighs 93 pounds (lb). Meperidine hydrochloride is ordered for pain at a dosage of 6 milligrams (mg) per kilogram of b

Ymorist [56]

Convert the dose into mg / lb

1 lb = .45 Kg

so the does = 6 * .45 = 2.7 mg/lb

so the daily dose of the patient is 93 * 2.7 = 251.1 mg

injections are available in 50mg per mL

to calculate the daily dose in mL 251.1 / 50 = 5 mL

murzikaleks [220]

Step-by-step explanation:

1. if to evaluate the given experssion, then

7⁶(7²-7+1)=7⁶*43.

2. if to divide this evaluated expression by 43, then

7⁶*43/43=7⁶.
