How do you write (10, -6) and (-2, -6) as an equation

Mathematics
1 answer:
Paraphin [41]3 years ago
4 0

Answer:

y=-6

Step-by-step explanation:

Method 1:

Both the y coordinates of the points are the same and the x coordinates are distinct.

Therefore the straight line passing through the point is parallel to X-axis.

The common y coordinate is -6, therefore the line equation is y=-6.

Method 2:

We will solve it using general line equation

(y-y1)=(\frac{y2-y1}{x2-x1})(x-x1)

where (x1,y1) and (x2,y2) are the 2 points.

  • (y+6)=(\frac{-6+6}{10+2})(x+2)
  • (y+6)=0
  • y=-6

The area of a storage shed floor is 20 ft2. The length is 3 more than twice the width. Find the dimensions of the storage shed f
vladimir1956 [14]

Answer:

  • 2.5 ft wide
  • 8 ft long

Step-by-step explanation:

The given relation between length and width can be used to write an expression for area. The equation setting that equal to the given area can be solved to find the shed dimensions.

__

<h3>Given relation</h3>

Let x represent the width of the shed. Then the length is (2x+3), and the area is ...

  A = LW

  20 = (2x+3)(x) . . . . . area of the shed

__

<h3>Solution</h3>

Completing the square gives ...

  2x² +3x +1.125 = 21.125 . . . . . . add 2(9/16) to both sides

  2(x +0.75)² = 21.125 . . . . . . . write as a square

  x +0.75 = √10.5625 . . . . . divide by 2, take the square root

  x = -0.75 +3.25 = 2.50 . . . . . subtract 0.75, keep the positive solution

The width of the shed is 2.5 feet; the length is 2(2.5)+3 = 8 feet.

Write the expression in WORDS!<br><br> 5x + 3
Svet_ta [14]
The expression 5x+3 would be three more than five times a number! More than in this case would be addition - so if you get the same problem with subtraction you just change more to less!
Basically what it's tell you is that if x stood for 2 in this case 5*2 = 10 since it's 3 MORE than 5 times a number (x is in place of a number), you're adding 3 to 10 and that gives you 13!
I hope I simplified it a little more and you understand!
Good luck, rockstar! c: I hope this helped!
