Answer:

The expression given in the question i.e 6x + 6 + 5x - 8 in the simplified form is 11x -2 .

Step-by-step explanation:

As given the expression in the question be as follow .

= 6x + 6 +5x -8

Simplify the above expression and it can be written as .

= 6x + 5x + 6 - 8

= 11x -2

Therefore the expression given in the question i.e 6x + 6 + 5x - 8 in the simplified form is 11x -2 .

11x-2; SInce you have to add 6x and 5x because they are 'like terms' meaning they share the same variable. You also add the 6 and the -8, which is basically doing 6-8, which equals -2. So, you put these two numbers together to get an expression of 11x-2.

Answer:

  • a = 5

Step-by-step explanation:

<u>Simplify:</u>

  • √5(√8 + √18) =
  • √5*8 + √5*18 =
  • √40 + √90 =
  • √4*10 + √9*10 =
  • 2√10 + 3√10 =
  • (2 + 3)√10 =
  • 5√10

<u>The value of a:</u>

  • a√10 = 5√10

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
