Answer:
The first one
Step-by-step explanation:
You You need to make it 5 lb of crawfish so 6$ for 4 pounds is 12$
1 pound is 3$
4 pounds + 1 pound is 15$
Shop a and b is 15$
Answer:
y=3/5X+5/6
Step-by-step explanation:
Y=ax+b
(-4;-3) (6:3)
-3=-4a+b
3=6a+b
3-6a=-3+4a
6=10a
a=6/10=3/5
b=5/6
Answer:
<h2><u>
Graph A</u></h2>
Step-by-step explanation:
We know it must be graph A because when finding the most popularly bought item, the percentages only can go to 100%
So graphs C and D are eliminated.
Also since it never said any flavors were unknown, all the percents have to add up to 100%
So graph B is eliminated.
Only graph A follows the requirements
Solutions
To solve the equation we have to isolate 12y
Answer:
Solution (-2, 7)
Step-by-step explanation:
2x + 3y = 17 (1)
5x + 6y = 32 (2)
Using elimination method
Multiply (-2) to the equation (1)
-4x - 6y = -34
Now you have 2 new equations
-4x - 6y = -34
5x + 6y = 32
----------------------------Add
x = -2
Substitute x = -2 into 2x + 3y = 17
2(-2) + 3y = 17
- 4 + 3y = 17
3y = 21
y = 7
Solution (-2, 7)
