Write the slope-intercept form of the line that passes through (1, -2) and is parallel to the line y = 4x + 2.
Naily [24]

Use

y-y1=m(x-x1)

y-(-2)=4(x-1) Now why 4??Because parallel lines have the exact same slope

y+2=4x-4

y=4x-4-2

y=4x-6

Hope it helps!

abruzzese [7]

Answer:

  the cylinder volume is greater

Step-by-step explanation:

The volume of a cube with x=1 is ...

  V(1) = 1^3 = 1

The graph shows y ≈ 1.5 for x=1. Since 1.5 > 1, the volume of the cylinder is greater.

snow_lady [41]

Answer:

Muscles Gym: 13.33

Energy Gym: 15.00

Step-by-step explanation:

Muscles Gym: You divide "40.00" by "3", which will then give you the answer of "13.33".

Energy Gym: You divide "93.00" by "6", which will then give you the answer of "15.50".

You then add the zero to show the proper number of cents after the decimal point.

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.
