5x+12y=-34
2x+4y=-12

Answers

Answer 1

Answer:

x = -2 y= -2

Step-by-step explanation:

5x+12y= -34

2x+ 4y = -12

2x= -4y -12

x= -2y -6

plug back in

5(-2y -6) +12y = -34

-10y -30 +12y = -34

2y = -4

y= -2

2x+4y=-12

4y= -2x -12

y= -.5x -3

plug back in

5x+ 12(-.5x-3)=-34

5x -6x -36 = -34

-x = 2

x= -2

Answer 2

Answer:

Step-by-step explanation:

5x + 12y = -34

-6x - 12y = 36

-x = 2

x = -2

5(-2) + 12y = -34

-10 + 12y = -34

12y = -24

y = -2

First, let's let's evaluate the numerator and denominator separately.

The numerator: (-2)^2(3)(4) - (-1) = 48 + 1 = 49

The denominator: (-2)^2 = 4

Now that the numerator and denominator are simplified, let's take the square root of 49/4

sqrt(49/4) = 3.5

A triangle with the coordinates X(3, 2), Y(5, -1), and Z(-2, 3) is reflected across both the x- and y-axes. The coordinates after both reflections are what

Answers

Answer:

The coordinates of the reflected triangle are [tex]X'(x,y) = (-3,-2)[/tex], [tex]Y' (x,y) = (-5,1)[/tex] and [tex]Z'(x,y) = (2,-3)[/tex].

Step-by-step explanation:

Let be a point [tex](a,b)\in\mathbb{R}^{2}[/tex], reflections across x- and y-axes are represented by the following operations:

x-Axis reflection:

[tex]d = d'[/tex]

[tex]b - 0 = 0 - b'[/tex]

[tex]b' = -b[/tex]

y-Axis reflection:

[tex]d = d'[/tex]

[tex]a - 0 = 0 - a'[/tex]

[tex]a' = -a[/tex]

If we know that [tex]X (x,y) = (3,2)[/tex], [tex]Y(x,y) = (5,-1)[/tex] and [tex]Z (x,y) = (-2, 3)[/tex], the coordinates after both reflections are, respectively:

[tex]X'(x,y) = (-3,-2)[/tex]

[tex]Y' (x,y) = (-5,1)[/tex]

[tex]Z'(x,y) = (2,-3)[/tex]

The coordinates of the reflected triangle are [tex]X'(x,y) = (-3,-2)[/tex], [tex]Y' (x,y) = (-5,1)[/tex] and [tex]Z'(x,y) = (2,-3)[/tex].

Find the distance between the points (2,9) and (8,2)

Answers

So the distance between two points formula is :
c= the square root of (x1-x2)^2 + (y1-y2)^2

Therefore ...
(8-2)^2 + (2-9)^2
6^2 + (-7)^2
36+49= 85
Square root of 85= 9.22 approx.
Hence, the distance between the two points is 9.22

if someone weighs five times as much as someone else and the total weight of the two people is 132 pounds how much does each person weight

Answers

Answer:

The heavier person weighs 110 pounds, and the lighter person weighs 22 pounds.

Step-by-step explanation:

Let the weight of the lighter person be 1 unit.

The weight of the heavier person will be [tex]1\times 5=5u[/tex]

Total weight: [tex]1u+5u=6u[/tex]

6 units = 132

Divide 6:

[tex]1u=\frac{132}{6}[/tex]

[tex]1u=22[/tex]

The weight of the lighter person is 22 pounds.

Weight of the heavier person [tex]= 5\times 22=110[/tex]

The weight of the heavier person is 110 pounds.

Step-by-step explanation:

someone= 5x

someone + x= 132

5x + x = 132

6X=132

x=22

One person ("someone") weighs x× 5 = 110.

the other person ("x) weighs x = 22
