heather has divided $6300 between two invesments, one paying 9%, the other paying 4%. If the return on her investment is $372, h

Ganezh [65]

Assuming that the two investments are X & Y
X + Y = 6300
X = 6300 - Y (1)

9/100X + 4/100 Y = 372 (2)
replacing X from (1) into (2)
9/100(6300-Y) + 4/100 Y = 372
567 - 9/100Y +4/100Y = 372
(-9+4)/100Y = 372 - 567
5/100Y = -195
Y = 100*195/5 = 3900
From (1) we can get X
X = 6300 - 3900 = 2400

Identify the angle relationship, then solve for x*

goblinko [34]

Answer:

14°

Step-by-step explanation:

(7x-1)°+(6x-1)°=180°(sum of angles in a straight line/being linear pair)

or,7x-1°+6x-1°=180°

or,13x-2°=180°

or,13x=182°

or,x=182°/13

or,x=14°

What is the equation of a line that passes through the point (6, 1) and is perpendicular to the line whose equation is y=−2x−6y=

Mandarinka [93]

Lets get the negative reciprocal of the slope so we get
$m = \frac{1}{2}$
Now the equation that is perpendicular is
$y = \frac{1}{2} x + b$
Lets solve for b by plugging in the point (x,y)=(6,1)
$1 = \frac{1}{2} (6) + b \\ 1 = 3 + b \\ 1 - 3 = b \\ b = - 2$
Now plug that into the equation. So the equation of the line that is perpendicular and
passes through the point (6, 1) is
$y = \frac{1}{2} x - 2$
