15x^2+14x-49=0\\\\&#10;Terms:\\&#10;a=15\ \ \ \ b=14\ \ \ \ c=-49\\&#10;Quadratic\ Formula:\\\\&#10;x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\&#10;x=\dfrac{-14\pm\sqrt{196+2,940}}{30}\\\\&#10;x=\dfrac{-14\pm\sqrt{3,136}}{30}\\\\&#10;x=\dfrac{-14\pm56}{30}

Roots:\\\\&#10;x'=\dfrac{-14+56}{30}\\\\&#10;x'=\dfrac{42}{30}\\\\&#10;x'=\dfrac{21}{15}\\\\&#10;\boxed{x'=\dfrac{7}{5}}\\\\\\\\&#10;x''=\dfrac{-14-56}{30}\\\\&#10;x''=\dfrac{-70}{30}\\\\&#10;\boxed{x''=\dfrac{-7}{3}}

Fantom [35]

Answer:

A. the equality means that the two equations should be equal in a certain x value. Solving the x for these equation gives you the x point where the 2 equations intersect.

B. The x value where the funcionts intersect is x = 1

Step-by-step explanation:

You can solve the x value using natural logarithms.

If you make a table for the two functions you will also see the result:

Value             y = 8^x            y = 2^(x+2)

 -3                    0,00195          0,5

 -2                    0,0156             1

 -1                     0,125               2

  0                     1                      4

  1                      8                     8

  2                      64                  16

  3                      512                  32
