Complete Question

Yana though of a number she multiplied it by 8 subtracted 4 divided the result by 2, and got 30. What number did Yana think of

Answer:

x=8

Step-by-step explanation:

From the question we are told that:

Thought of Number x

Multiplied it by 8

 x*8=8x

Subtracted 4

 8x-4

Divided the result by 2

 \frac{8x-4}{2}

Generally the equation for x is mathematically given by

 \frac{8x-4}{2}=30

 8x-4=60

 8x=60+4

 x=8

What are the two things do you need to write an equation?
dlinn [17]

Answer:

Slope and y intercept.

Step-by-step explanation:

This is necassary to write the equation of a line in y=mx+b

m is where the slope goes, and b is the y intercept.

Alternatively, you could also write the equation for a line with a point on the line and the slope.

You would then write it in point slope formula:

y-y1=m(x-x1)

This can later be converted into slope intercept form.

If a quadratic equation has a discriminant that equals zero, which of the following statements is always true?
kotegsom [21]

Answer:

d. The equation has one solution and there is not enough information to determine the direction of the parabola.

Step-by-step explanation:

For a general quadratic equation

y = ax² +bx +c

the solution is

x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

The discriminant (D) is the part of the quadratic formula underneath the radical: b² - 4ac.

D tells us whether there are

  • two different real solutions
  • two identical real solutions ("one solution")
  • two complex solutions.

If D= 0,

x = \dfrac{-b}{2a}\pm0 = \mathbf{\dfrac{-b}{2a}}

and there are two identical solutions ("one solution").

The direction of the parabola depends on the sign of a.

That information is not given, so we cannot determine the direction of the parabola.
