3x+y=23, 6x-y=50, what is the value of x and y

Mathematics
1 answer:
Mice21 [21]2 years ago
4 0

Answer:

3x+y=23

6x-y=50

2(3x+y)=2(23)

6x+2y=46

(6x-y)-(6x+2y)=50-46

-3y=4

y=-4÷3

=-4/3

x=[23-(-4/3)]÷3

=24/1/3÷3

=73/3÷3

=73/9

Find the equation of the line parallel to the line y = 4x – 2 that passes through the point (1, 5).
Lesechka [4]

Answer:

4x-y+1=0

Step-by-step explanation:

here,given equation of a line id

4x-y-2=0.. eqn(i)

equation of any line parallel to line (i) is

4x-y+k=0...eqn(ii)

since, the line(ii) passes through (1,5)[replacing x=1 and y=5 in eqn(ii), we get]

4*1-5+k=0

or, 4-5+k=0

or,-1+k=0

•°•k=1

substituting the value of k=1 in eqn(ii),

4x-y+1=0 is the required equation of the line.

Find x. Leave answers in simplified radical form. (Step by step)
just olya [345]

Answer:

\sf x  = 4\sqrt{2}

Given:

  • adjacent: 4 cm
  • hypotenuse: x cm
  • angle: 45°

<u>using cosine rule:</u>

\sf cos(x)  = \dfrac{adjacent}{hypotenuse}

\sf cos(45)  = \dfrac{4}{x}

\sf x  = \dfrac{4}{cos(45)}

\sf x  = 4\sqrt{2}
