Find the equation of the graph given below. Notice that the cosine function is used in the answer template, representing a cosine function that is shifted and/or reflected. Use the variable x in your equation rather than the multiplication × symbol.

y= __COS(__)+(__)

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

i think the answer is c sorry if it's wrong

hi there!

1. define: accuracy

a) how close a measured value is to the actual (true) value.

hope this : )
