answer
system : 8L+ 4S = 120
L + S = 20
There are 10 small packs and 10 large packs
step by step answer :
to form the two systems, we have to determine the catagories of the 2 equations : one for money and one for the no of packs
after forming the two equations we simply put the numbers in the same order put above on the calculator ( mode 5:1) and the calaculator will answer it in seconds . 10 small packs and 10 large packs.
To check your answer , substitute the letters with their values and if both equations gave you the same value at the end then your answer is correct!
Answer:
(-3, 0), (0, -9)
Step-by-step explanation:
x-intercept: Let y = 0 and find x: 0 = -3x - 9), or 3x = -9. Then x = -3, and the x-intercept is (-3, 0).
y-intercept. Let x = 0 and find y. y = -3(0) - 9 = -9. The y-intercept is (0, -9).
Answer:
Step-by-step explanation:
Multiplying x+6y=-3 with 2 so its equal to first eqn,
Eliminating,
2x + 3y = 3 (1)
2x +12y = -6 (2) (because subtracting)
------------------
-9y =9
∴y=-1
eq. y in 1
2x -3=3
2x=3+3
x=6/2
=3

Answer:
7a+28b=21
Step-by-step explanation:
7×a=7a
7×-3= -21
7×+4b=+28b
so....
7a-21+28b=0
7a+28b=21
