No, one is a X which is the left to right line, and one is Y which is the up and down line, they are to different letters, not the same sign hopefully that helps

The X coordinates are the bottom part of a graph and Y coordinates are at the up & down part of a graph. Hopefully that answers your question.

A drone has an effective range represented by a circle on a coordinate plane. The points (–12, 3) and (–6, –5) are endpoints of
Mrac [35]

Answer:

(x+9)^2 + (y+1)^2 = 100

Step-by-step explanation:

Since the question says diameter, we know the boundary in a circle. Therefore, we just need to find the center and radius.

The center is the midpoint of the two endpoints on a diameter.

Here, it is (-9, -1).

Therefore, the left part of the equation is (x- -9)^2 + (y - -1)^2 = (x+9)^2 + (y+1)^2.

The radius: sqrt(8^2 + 6^2) = 10

So the equation is (x+9)^2 + (y+1)^2 = 100

What is the gradient of a line with an equation of 3x-2y-6=0​
Genrish500 [490]

Answer:

Slope <em>m</em> = 3/2

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define Equation</u>

3x - 2y - 6 = 0

<u>Step 2: Rewrite</u>

<em>Find slope-intercept form</em>

  1. Subtract 3x on both sides:                    -2y - 6 = -3x
  2. Add 6 on both sides:                             -2y = -3x + 6
  3. Divide -2 on both sides:                         y = 3/2x - 3

<u>Step 3: Break Function</u>

<em>Identify Parts.</em>

Slope <em>m</em> = 3/2

y-intercept <em>b</em> = -3

The tank at a gas station contained 400 gallons of gas. A tanker truck that contained 8,100 gallons of gas filled the station's
spin [16.1K]

Answer:

1300

Step-by-step explanation:

Let the amount put in the station's tank = x

4(400 + x) = 8100 - x                           Remove the brackets

1600 + 4x = 8100 - x                            Subtract 1600 from both sides

1600 - 1600 + 4x = 8100 - 1600 - x     Do the subtraction

4x = 6500 - x                                        Add x to both sides

4x + x = 6500 - x + x        

5x = 6500                                            Divide by 5

5x/5 = 6500/5                                      

x = 1300

1300 gallons were added to the station's tank.

3. Evaluate a + b for a = -46 and b= 34.<br> A:-12<br> B:80<br> C:-80<br> D:12
blsea [12.9K]

Answer:

<h2>A: -12</h2>

Step-by-step explanation:

Put the values of a = -46 and b = 34 to the expression a + b:

-46 + 34        <em>use the commutative property a + b = b + a</em>

= 34 + (-46) = 34 - 46 = -12
