Evgen [1.6K]

Answer:

$2(y+2)$

Step-by-step explanation:

Let

y --->Mala's age

x---> sister's age

we know that

$x=y+4$ ---> equation A

The sum of ages of the sisters is

$x+y$

substitute equation A in the expression of the sum of ages

$(y+4)+y=2y+4$

simplify

$2(y+2)$

14. Find the slope of a line parallel to 3y - 6x = 9. (Lesson 3-4)

DanielleElmas [232]

$\bf 3y-6x=9\implies 3y=6x+9\implies y=\cfrac{6x+9}{3}\implies y = \cfrac{6x}{3}+\cfrac{9}{3} \\\\\\ y = \stackrel{\stackrel{m}{\downarrow }}{2}x+3\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}$

a parallel line to that one above, will have the same exact slope, since parallel lines have the same slope.

(115) the product of integers x, y, and z is even. is z even?

djyliett [7]

1. X/Y = Z

if x = 6, y = 2, then z = 3, not even

if x = 6, y = 3, then z = 2, even

<span>2. Z=XY </span>

so (z)^2 = 2*k (because x*y*z = 2k, where k is an integer)

<span>Sufficient, as if square of an integer is even ,then the integer is even</span>
