Step-by-step explanation:
answer:
turkey sandwich = $6.50
salad = $5.50
explanation:
first, write equations to represent the problem.
4t+2s=37
t-s=1
then, you can use elimination, then algebra.
2t-2s=2
6t=39
3t=13
Step-by-step explanation:
5(3x+2)-2(4x-1)
15x+10-8x+2
7x+12
It could have took a day or a million. there isn't enough info
Answer:
b. (0,-3) (1,-5) (-1,-1)
Step-by-step explanation:
we only have to replace the first part of the parenthesis by x and the second part by y, and see if equality is met
y = -2x - 3
a.
(0,-3) (-1,-4) (-1,-5)
y = -2x - 3
-3 = -2(0) -3
-3 = -3
-4 = -2(-1) - 3
-4 = 2 -3
-4 = -1
WRONG OPTION
b.
(0,-3) (1,-5) (-1,-1)
y = -2x - 3
-3 = -2(0) -3
-3 = -3
-5 = -2(1) - 3
-5 = -2 -3
-5 = -5
-1 = -2(-1) -3
-1 = 2 -3
-1 = -1
CORRECT OPTION
c.
(0,-3) (1,4) (-1,-5)
y = -2x - 3
-3 = -2(0) -3
-3 = -3
4 = -2(1) -3
4 = -2 -3
4 = -5
WRONG OPTION
d.
(0,-3) (1,-4) (-1,-5)
y = -2x - 3
-3 = -2(0) -3
-3 = -3
-4 = -2(1) -3
-4 = -2 -3
-4 = -2
WRONG OPTION
