Write the equation of a line that is perpendicular to the line that passes through (4,−3)and (−7,8).
masha68 [24]

Line perpendicular to a given line is = 1/m

To find m, use m =y2-y1/x2-x1 formula

m = (8-(-3))/(-7-4)

m = 11/-11,

m = -1

Use y= mx+c to find equation of line

Plug in a pair of values,

-3= -1(4)+ c

c= 1

Thus, equation is:

y = -x+1

Equation of line perpendicular to this line is:

y= x+1

Hope it helps :)

There are a total of 84 students in a robotics club in the science club. The science club is 12 more students in the robotics cl
Anna [14]

Answer:


Step-by-step explanation:

Let the Number of students in the Robotics club be x

So , the number of students in the Science club must be x+12

(Because it is given that the science club have 12 more students.)

Total number of students = 84

So ,

x+(x+12)=84

combining the like terms we get

2x+12=84

Subtract 12 from both sides

2x=72

Divide both sides by 2

x=36

So ,


Number of students in the Robotics club = 36

Number of students in the Science club =36+12 = 48

An arithmetic sequence has this recursive formula:
ankoles [38]

Hello!


The recursive rule for an arithmetic sequence: a_{n} = a_{n-1} + d.

The explicit rule for an arithmetic sequence: a_{n}=a_{1} +d(n-1).


a_{n} is the value you are trying to find, or simply the answer. :)

d is the common difference of the sequence.

a_{1} is the first term of the sequence.


Given, a_{1} = 8 and a_{n}=a_{n-1} - 6...

The common difference is -6, and the first term is 8.


Plug these values into the explicit rule for an arithmetic sequence, you get:

a_{n}=8+(-6)(n-1).


Therefore, the answer is A, a_{n}=8+(n-1)(-6).


If you wondered why, a_{n}=8+(-6)(n-1) is equal to a_{n}=8+(n-1)(-6), the Commutative Property of Multiplication states that when two numbers are multiplied together, the answer is the same regardless of the order of the numbers, which makes a_{n}=8+(-6)(n-1) and a_{n}=8+(n-1)(-6) equal to each other.
