Y=2x+9 y=6−x what is the solution??

Mathematics
1 answer:
Monica [59]3 years ago
7 0

Step-by-step explanation:

y=2x+9

y=6−x

(y-2x=9)(-1)

y+x=6

-y+2x=-9

y+x=6

3x=-3

x=-3/3=-1

sub x=-1 in eq 1

y-2(-1)=9

y+2=9

y=9-2=5

so (-1;5) is the only solution for this system

(hope it's correct)

What is the surface area of the triangular prism?
stepladder [879]

Answer:

<h2>135 ft²</h2><h2 />

Step-by-step explanation:

surface area = bh + L(s1 + s2 + s3)

where b = 2.5 ft.

           h = 6 ft.

          s1 = 6.5 ft.

          s2 = 6 ft.

         s3 = 2.5 ft.

          L = 8 ft.

<u>plugin values into the formula: </u>

A = 2.5*6 + 8(6.5 + 6 + 2.5)

   = 15 + 8(15)

   = 135 ft²

Which system is equivalent to 3x squared - 4y squared = 25 over -6x squared -2y squared = 11
TEA [102]
So we are given the following system:
3x^2-4y^2=25\\&#10;-6x^2-2y^2=11\\\text{Multiply the second equation by -2:}\\12x^2+4y^2=-22\\\text{Add to the first equation we get:}\\15x^2=3&#10;\text{ therefore }x=\pm \sqrt{ \frac{1}{5} }
Using the first equation again we get:
3x^2-4y^2=25\\&#10;3x^2=4y^2+25\\&#10;x^2= \frac{1}{3}(4y^2+25)\\x^2= \frac{1}{3}(4 \frac{1}{5} +25)\\= \frac{43}{5}\\x=\pm \sqrt{ \frac{43}{5} }
