Answer:
(x, y, z) = (-1, 0, -3)
Step-by-step explanation:
We notice that the coefficients of z are such that elimination of the z term from the equations is made easy.
Adding equations 1 and 2:
(2x -3y -2z) +(x +3y +2z) = (4) +(-7)
3x = -3
x = -1
Adding equations 2 and 3:
(x +3y +2z) +(-4x -4y -2z) = (-7) +(10)
-3x -y = 3
Substituting for x, we get ...
(-3)(-1) -y = 3
0 = y . . . . . . . . . . . add y-3 to both sides
Then z can be found from any equation. Substituting for x and y in the second equation gives ...
-1 +2z = -7
2z = -6 . . . . . add 1
z = -3 . . . . . .divide by 2
The solution is (x, y, z) = (-1, 0, -3).
Ur answer is : h(d) = 2d + 3
because if u sub in the points in ur table, this equation works....with the number of months being d and the length of the hair being h(d)
Answer:
6 cookies
Step-by-step explanation:
first, find how much money they spent on cupcakes
6 × $2.25 = $13.5
then, take $13.5 and subtract that by $24
$24 - $13.5 = $10.5
so the person spent $10.5 on cookies. divide the amount per cookie by $10.5
$10.5 ÷ $1.75 = 6
so they bought 6 cookies
