Perpendicular means the slope is the opposite inverse
Lets re-organize the equation so its more friendly
4x-2y=9
-2y=-4x-9
y=2x+9/2
The slope of this is 2, so the opposite inverse would be -1/2
So far our new equation looks like y=-1/2x+b
To find B we will input the coordinates (4,6) for their respective x,y values
6=-1/2(4)+b
6=-2+b
b=8
y=-1/2x+8
The answer is B

Under which condition does a country with a small GDP have a large per capita income? if it has a large population if it has a s
ratelena [41]
Per capita means per head or per person.

now, if a country has a small GDP hmmm say for the sake of example, $1000, and it has 1000 residents, then the per capita is $1000/1000 or a buck each.

now, $1000 is a really tiny GDP, but, if the population is say hmm 20 folks only, then the per capita amount is $1000/20, or $50 per person, now, that's a large "per capita" figure, more so than $1 per person, even though the GDP never changed, it was all along $1000.

so, if the population is comparitively small, the per capita is large, I think a good example of that is Switzerland.

sidenote:

bear in mind that per capita figures are very misleading, since you could have a tiny portion of the population making huge amounts and others making little, like in the US, and the per capita is very inaccurate to reflect the economy wealth distribution.

Katarina [22]

Answer:

35 times StartFraction 5 Over 7 EndFraction

Step-by-step explanation:

Alejandro has gone to school (5/7) of the last 35 days.

We need to find the expression that can be used to determine the number of days Alejandro has gone to school.

x=\dfrac{5}{7}\times 35\\\\=5\times 5\\\\=25

So, the correct option is (b) "35 times StartFraction 5 Over 7 EndFraction".
