1 answer:

WARRIOR [948]3 years ago

6 0

Answer:

Step-by-step explanation:

Let the number of the birds apart from the newcomer, be x.

x/2 + 1 = 100

which means,

x/2 = 100 - 1,

this gives us a 99.

x/2 = 99.

To get the actual number and kill the fraction we multiply by 2.

x = 2 x 99

...

x= 198...

Therefore,

The total birds flying were 198.

PROOF:

198/2 = 99.

99+ 1 = 100.

That one added to the 99 is the newcomer bird.

From what you are describing you should just simply plug in the x and y coordinates.

-2(-2)+4(1)=8

-2(0)+4(2)=8

Write an expression for “5 more pounds than joe”

LenKa [72]

Answer:

x+5

Step-by-step explanation:

Since you don't know how much Joe weighs, you can express his weight as x. Then, you add on 5 because you have 5 more lbs than joe (which is x).

A vertex of square is at(1,1) and its two parallel sides are y=x and y=x+1. find the equation of the remaining sides.Show your w

belka [17]

Answer:

$\displaystyle y = - x + 2$

$y = - x +1$

Step-by-step explanation:

we are given a vertex of a square i.e (1,1)

and the equations of the two parallel sides

notice that, the given vertex coordinates satisfy one of the parallel side i.e y=x which means that (1,1) points lie on one of Parallel sides

remember that,

every angles of a square is 90°

therefore,

we need to figure out the remaining Perpendicular line of the given Parallel sides so

let's figure out the perpendicular line of y=x line

recall that,

Parallel lines have the same slope thus

$\displaystyle m_{ \rm perpedicular} = - 1$

since we are given a vertex the equation of the perpendicular line should be

$\displaystyle y - 1 = - 1(x - 1)$

distribute:

$\displaystyle y - 1 = - x + 1$

add 1 to both sides:

$\displaystyle y = - x + 2$

to figure out the second perpendicular line we can consider the coordinates (0.5,0.5) of y=x equation

so the slope of the perpendicular line is -1

and the equation:

$y - 0.5 = - 1(x - 0.5)$

distribute:

$y - 0.5 = - x +0 .5$

add 0.5 to both sides:

$y = - x +1$

and we are done!
