Answer:

Step-by-step explanation:

P(-2,-1) and Q(4,3)

average of x-coordinates = (-2+4)/2 = 1

average of y-coordinates = (-1+3)/2 = 1

midpoint of PQ: (1,1)

distance between midpoint and Q = √((4-1)²+(3-1)²) = √13

(x-1)² + (y-1)² = 13

Simplify x^1/3(x^1/2+2x^2)

Marizza181 [45]

Answer:

$x^{5/6 } + 2\cdot x^{7/3}$

Step-by-step explanation:

Let be $x^{1/3}\cdot (x^{1/2} + 2\cdot x^{2})$ , which can be simplified solely by algebraic means. We proceed to describe all the steps needed for simplification:

1) $x^{1/3}\cdot (x^{1/2} + 2\cdot x^{2})$ Given.

2) $x^{1/3}\cdot x^{1/2} + 2\cdot (x^{1/3}\cdot x^{2})$ Distributive and associative properties.

3) $x^{5/6 } + 2\cdot x^{7/3}$ $a^{m}\cdot a^{n} = a^{m+n}$ /Result

7(5x - 13) = 14

vfiekz [6]

Answer:

Part A, one solution

Part B, x=3

Step-by-step explanation:

divide both sides of the equation by 7 (5x-13=2)

move the constant to the right hand side and change its sign (5x=2+13)

add numbers (5x=15)

divide both sides of the equation by 5 (x=3)

hope this helps, have a good day
