Given: x + 2y = -6.

Solve for y.

Answers

Answer 1

Answer: $x + 2y =-6$

Subtract x on both sides

$x + 2y-x =-6-x$

$2y =-6-x$

Divide by 2 on both sides

$(2y)/(2) =(-x-6)/(2)\n\ny =(-x-6)/(2)\n\n \boxed{\bf{y=-(1)/(2)x -3}}$

c) $187.68
d) $88.95

If it's not too much to ask, could you thoroughly explain it with exact steps so I can do it myself. Thank you plenty.

Answers

163 cost $144.99
211 cost ????

211 * 144.99 / 163
= 30,592.89/163
=187.68

Answer is c) $187.68

Answer:

$187.68

A circle is centered at the point (-3, 2) and passes through the point (1, 5). The radius of the circle is ______ units. The point (-7, ______) lies on this circle.How would I do this?

Answers

circle formula
(x-h)^2+(y-k)^2=r^2 where (h,k) is the center
and r=radius

to find the radius
we are given one of the points and the center
distnace from them is the radius
distance formula
D= $\sqrt{(x2-x1)^(2)+(y2-y1)^(2)}$
points (-3,2) and (1,5)
D= $\sqrt{(1-(-3))^(2)+(5-2)^(2)}$
D= $\sqrt{(4)^(2)+(3)^(2)}$
D= $√(16+9)$
D= $√(25)$
D=5

center is -3,2
r=5
input
(x-(-3))^2+(y-2)^2=5^2
(x+3)^2+(y-2)^2=25 is equation
radius =5
input -7 for x and solve for y
(-7+3)^2+(y-2)^2=25
(-4)^2+(y-2)^2=25
16+(y-2)^2=25
minus 16
(y-2)^2=9
sqqrt
y-2=+/-3
add 2
y=2+/-3
y=5 or -1

the point (-7,5) and (7,-1) lie on this circle

radius=5 units
the points (-7,5) and (-7,1) lie on this circle

How do you solve this two step equation 6=a/4+2

Answers

First you need to subtract the 2 over to the left side:
4=a/4
Then, multiply both sides by 4 in order to get the 4 on the right to cancel out of the denominator:
16=a

Subtract 2 from both sides then multiply both sides by 4

Data are drawn from a symmetric and bell shaped distribution with a mean of 120 and a standard deviation of 5. There are 900 observations in the data set. What percentage of observations are less than 130? How many observations are less than 130? This is suppose to be two different questions but they seem the same to me. Please please please help me.

Answers

How many requests an actual number, not a percent. To get the number from the percentage, assume you've got p% observations (which is 97.5%). The actual number of observations is p*900/100, that is 9 times the 97.5% or 877.5 observations (I know, odd thing you get a non-integer). I guess I got the wrong percentage (I don't do statistics just yet at school ;) )
