Indicate all possible values for the variable in each of the expressions: sqrt(2x+2)+sqrt(6-4x)
IrinaK [193]

Answer:

<u>Given expression:</u>

  • \sqrt{2x+2}+\sqrt{6-4x}

<u>The first root is valid when:</u>

  • 2x + 2 ≥ 0 ⇒ 2x ≥ - 2 ⇒ x ≥ - 1

<u>The second root is valid when:</u>

  • 6 - 4x ≥ 0 ⇒ 4x ≤ 6 ⇒ x ≤ 1.5

<u>So the variable x can get values within interval:</u>

  • -1 ≤ x ≤ 1.5 or
  • x = [-1, 1.5]

What is the equation of the line passing through the point (-2,-1) and perpendicular to the line y = 1/2x+5?
uranmaximum [27]

Step-by-step explanation:

the slope of a line is always the factor of x.

here : 1/2

it is the ratio y/x indicating how many units y changes, when x changes a certain angina amount of units when going from one point to another.

a perpendicular slope puts x and y upside-down and flips the sign.

here : -2/1 = -2

so, the equation looks like

y = -2x + b

b is the y-intercept, and we get this by putting the x and y coordinates of the given point into this equation and solve for b :

-1 = -2×-2 + b

-1 = 4 + b

b = -5

the full equation is therefore

y = -2x - 5

If angle 1 is 110°, what would the other angle measures have to be in order for m || n and
ra1l [238]

Answer:

Angle 2: 110 degrees, 1 and 2 would have to be the same for the lines to be parallel

Angle 3: 70 degrees angle 3 would have to be the complement to angle 1, so 1+3=180 and 70*3=180, so 3=70 degrees

Angle 4: 70 degrees, 3 and 4 have to be the same opposite angles for the lines to be parallel
