1) 6x-5 = 2x + 7

4x=12 and x =3

2) since PQ//SR, Ange S is the supplement of angle P
 31° + P° =180°, and P° = 149°

3) The kite has a symmetric axis that is y-axis and
the coordinate of E(w,0)

4) The midpoint of WX:. Let M be the Midpoint
Formula to find the coordinates of Midpoint, knowing the coordinates
of W(0,4b) and X(2a,0) is:
the x of M = (x₁+x₂)/2 = (0+ 2a)/2 =a
and the y of M =(y₁+y₂)/2 = (4b+0)/2 =2b, so M(a,2b)

The sum of two consecutive integers is at most 3. what is the greatest possible value for the greater integer?
Rudik [331]
2 consecutive integers...x and x + 1

x + x + 1 < = 3
2x + 1 < = 3
2x < = 3 - 1
2x < = 2
x < = 1

x + 1 = 1 + 1 = 2.......the greatest possible value for the greatest integer is 2

Hey Guys!
zaharov [31]
<h3>Answer: D)  -3</h3>

Explanation:

Recall that y = f(x) since both are outputs of a function.

If k = 2, then f(x) = 2 leads to y = 2 being a horizontal line drawn through 2 on the y axis. This horizontal line only crosses the cubic curve at one spot. The same can be said if k = 0 and k = -2. So we can rule out choices A,B,C.

On the other hand, if k = -3, then f(x) = -3 has three different solutions. This is because the horizontal line through -3 on the y axis crosses the cubic at 3 different intersection points.
