Leona [35]3 years ago
7 0

Answer:

1. x + y = 25

2. x - y = 7

3. x = 16, y = 9

Step-by-step explanation:

(x + y = 25) + (x - y = 7)

2x (the y cancels) = 32

32/2 = 16, x = 16

substitute x in either equation

16 + y = 25

y = 9

Find the distance between xequals[Start 2 By 1 Matrix 1st Row 1st Column 8 2nd Row 1st Column negative 5 EndMatrix ]and yequals[
kherson [118]

Answer:

Distance =√(x₁ - y₁)²+ (x₂ - y₂)² = √97 = 9.85

Step-by-step explanation:

The Matrix X and Y could also be referred to as vectors in Rⁿ dimensions.

if Vector X = ( x₁ , x₂)   and  Vector  Y = (y₁ , y₂)

then, Distance (X-Y) = ||X-Y|| = √(x₁ - y₁)²+ (x₂ - y₂)²

where, x₁ = 8, x₂ = -5   and  y₁ = -1 , y₂ = -9

Distance = √(8 - (-1))²+ (-5 - (-9))² = √9² + 4² =√97 = 9.85

Perimeter of a triangle = Sum of all the three sides of a triangle

  • Perimeter = 3a
  • where, a is the length of the each sides of a triangle.

⇒ 32 = 3a

Please help me out!!!!!!!!!!!!
Lesechka [4]

9514 1404 393

Answer:

  see below

Step-by-step explanation:

A number line usually has numbers increasing from the right. If each unit on the number line represents $100, then a gain of $500 would be represented by the point at +5 units (right of 0). The loss would be represented by a point at -5 units, located left of 0.

The points are equidistant from 0 in opposite directions.
