The page numbers of book are 203 and 204.

Step-by-step explanation:

Let,

the two consecutive integers are;

x, x+1

Sum of integers = 407

x+(x+1)=407\\x+x+1=407\\2x=407-1\\2x=406\\

Dividing both sides by 2

\frac{2x}{2}=\frac{406}{2}\\x=203

Therefore,

the two integers are;

x = 203

x+1 = 203+1 = 204

The page numbers of book are 203 and 204.

Find the coordinates of point P on →AB that partitions the segment into the given ratio AP to PB .
marysya [2.9K]

The line segment AB is divided at point P, which has coordinates P(0,-7.5)

A line segment is a section of a line that connects two locations to create a straight line or we can say that is connects two distinct points together to form a single line. It is extendable to either side.

Given are,

A line segment AB with coordinates of A(0,0 ) and B(-15,0) respectively

Two minor line segments, AP and PB, are created from the line segment AB by the provided point P

We must determine the dividing point's coordinates, or P.

We'll apply the formula provided,

The coordinates of the point P are given by  = (\frac{x1+x2}{2},\frac{y1+y2}{2} )

Now, x1 = 0, x2 = 0, y1 = -15, y2 = 0

Putting values in the formula, we get

(\frac{0+0}{2}, \frac{0-15}{2})

(0,-7.5)

Hence, the point P which partitions the line segment AB have coordinates as P(0,-7.5)

-1/2y=1/2x+5 and y=2x+2
Anettt [7]

I assume this is the intersection of two lines, i.e. -1/2y is (-1/2)y.  Please tell me if it's really -1/(2y).

(-1/2)y=(1/2)x+5

Multiplying both sides by -2

y = - x - 10

The other equation is

y = 2x + 2

We can equate them to find the meet

y = - x - 10 = 2x + 2

-3x = 12

x = -4

y = 2x + 2 = -6

Check:  (-1/2)y=3, (1/2)x+5=3, equal, good

2x+2=2(-4)+2=-6=y, good

Answer: x=-4, y=-6
