Can someone please help me with these ?

Mathematics
1 answer:
Pavel [41]3 years ago
7 0

Answer:

Step-by-step explanation:

11)  \sqrt{8x+33} =3\\8x+33=9\\8x=-24\\x=-3

Subtract 4 from both sides.  Square each side.  Subtract 33 from both sides.  Divide each side by 8.  Your answer is -3.

12)  7x-17=x^2-2x+1\\0=x^2-9x+18\\0=(x-6)(x-3)\\x=6,    x=3

Square both sides.  Put all numbers on one side of the equation so that you can be equal to zero.  Factor out and solve for x.

What is not a description of slope?
Gelneren [198K]

Answer:

Option (d) is wrong.

Step-by-step explanation:

Slope is:

  • rise over run
  • The rate of change of a line
  • Change in y over the change in x
  • <em><u>The ratio of vertical change  to the horizontal change. </u></em>

It can be given by mathematically as follows :

m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{and}\\\\m=\dfrac{dy}{dx}

Hence, the option which is not a description of slope is (d) "the ratio of horizontal change compared to vertical change"
