Point J(8,5) was translated as follows: J(8,5) ► J'(2,9). A student wrote the algebraic rule to describe the translation as
(x, y) → (x+6,7+4). Evaluate the student's answer.
A. Incorrect; the student should add 8+ 2 to calculate the x-coordinate and should add 5 + 9 to calculate
the y-coordinate.
B. Incorrect; the student added 4 to the y-coordinate instead of subtracting 4 from the y-coordinate,
C. Incorrect; the student added 6 to the x-coordinate instead of subtracting 6 from the x-coordinate,
D. The student's answer is correct.

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)

hey pal. the answer is b plz mark as brainliest
