Choose an equation in slope-intercept form for the line that passes through (-8,1) and is perpendicular to the y=2x-17.

Slope of perpendicular lines = opposite reciprocal
the slope of y = 2x - 17 is 2 or 2/1. 

we using opposite reciprocal
opposite reciprocal a/b is -b/a

2/1 would change into -(1/2)
now, input the value x and y, 
and the answer is c. y = -(1/2)x -3 

hope this help

a_sh-v [17]
First, find the z-score:

z = (value - mean) / sdev
  = (275 - 280) / 15
  = - 0.33

In order to use a standard normal table, we need a positive z-score:
P(z < -0.33) = 1 - P(z < 0.33)

Looking at the table, we find P(z < 0.33) = 0.6293

Therefore:
P(z < -0.33) = 1 - 0.6293 = 0.3707

Hence, you have a probability of about 37% <span>that a randomly selected pregnancy lasts less than 275 days.</span>

40 POINTSSS PLEASE HELPP!!
Katarina [22]
A) The inverse of the statement is the opposite. The statement stated that if two lines do not intersect, they are parallel. So, the opposite would be if two lines intercept, they are parallel. This inverse statement is false because, that is not true. Parallel lines mean they never intercept, not if they intercept its parallel.

b) Converse means to engage or explain, I think…so, the converse of the statement would be that yes, it is true that when two lines do not intercept then they are parallel. Because parallel lines never cross or meet, meaning they will NEVER ever have a crossing point.

c) the contrapositive of the statement would be: if two lines do not cross then they are parallel. If they do intercept, then they are not parallel. As simple as that. I think contrapositive means that…I looked what contrapositive means…so I think I’m right.

I hope this helps!! Or some at least. :)

Good luck!

Solve the system of linear equations below.
Mrac [35]

Answer:

I am not sure which one it is due to what you put in. I think it would be A.

x = 0

y = 2/3

Step-by-step explanation:

Step: Solve x + 6y= 4 for x:

x + 6y + −6y = 4 + −6y

x= −6y + 4

Step: Substitute −6y + 4 for x in 2x + 3y = 2:

2x + 3y = 2

2 (−6y + 4) + 3y = 2

−9y + 8 = 2

−9y + 8 + −8 = 2 + −8

−9y = −6

-9y/-9 = -6/-9

y = 2/3

Step: Substitute 2/3  for y in x = −6y + 4:

x = −6y + 4

x = -6 (2/3) + 4

x = 0

Sorry if it is long and confusing. But I hope this helps!

Solve the quadratic equation.<br> (a + 5)2 +36 = 9
Andrej [43]

Answer:

No solution unless you want to solve for an imaginary number which in that case a=27i-5

Step-by-step explanation:

(a+5)^{2} +36=9

(a+5)^2=-27

a+5=\sqrt{-27}

Here you can stop and say "no solution" since you cannot square root a negative number, but if you want you can still solve for an imaginary number:

a+5=\sqrt{-1} \sqrt{27}

a+5=27i

a=27i-5
