Answer:

\boxed{\sf{y=-50 \quad x=3}}

Step-by-step explanation:

Isolate the term of x and y from one side of the equation.

<h3>y=-15x-5 and 11x+y=-17</h3>

First, you have to substitute.

\sf{y=-15x-5=11x-15x-5=-17}

Then, you solve.

\sf{-4x-5=-17}

Add by 5 from both sides.

-4x-5+5=-17+5

Solve.

-17+5=-12

-4x=-12

Divide by -4 from both sides.

-4x/-4=-12/-4

Solve.

-12/-4=3

<u>x=3</u>

y=-15*3-5


Solve.

PEMDAS stands for:

  • Parenthesis
  • Exponents
  • Multiply
  • Divide
  • Add
  • Subtract

15*3=45

Rewrite the problem down.

y=-45-5

Solve.

<u>y=-50</u>

<u>Therefore, the correct answer is y=-50 and x=3.</u>

I hope this helps you! Let me know if my answer is wrong or not.

Find the standard form of the equation of the hyperbola satisfying the given conditions: X intercept +/- 6; foci at (-10,0) and
uysha [10]

Answer:

\frac{x^{2}}{36} - \frac{y^{2}}{64}=1

Step-by-step explanation:

Given an hyperbola with the following conditions:

  • Foci at (-10,0) and (10,0)
  • x-intercept +/- 6;

The following holds:

  • The center is midway between the foci, so the center must be at (h, k) = (0, 0).
  • The foci are 10 units to either side of the center, so c = 10 and c^2 = 100
  • The center lies on the origin, so the two x-intercepts must then also be the hyperbola's vertices.

Since the intercepts are 6 units to either side of the center, then a = 6 and a^2 = 36.

Then, a^2+b^2=c^2\\b^2=100-36=64

Therefore, substituting a^2 = 36. and b^2=64 into the standard form

\frac{x^{2}}{a^2} - \frac{y^{2}}{b^2}=1\\We \: have:\\ \dfrac{x^{2}}{36} - \dfrac{y^{2}}{64}=1
