First of all, we have to draw the line. To draw a line, we only need two points. To sample to points, we choose two arbitrary x values, and compute the correspondent y values.
We may choose x=0 and x=3 to make computation/drawing easier. We have
So, this line passes through the points (0, -6) and (3, -5). Draw these two points and connect them: you have the line
Now, to solve the inequality
recall that smaller values for y means "below" in the coordinate axes. So, every point that lies below the line is a solution to the inequality.
Answer:
Step-by-step explanation:
x = smaller number, y = bigger number
7x + 2y = 635
7y - 2x = 871....rearrange...-2x + 7y = 871
7x + 2y = 635....multiply by 2
-2x + 7y = 871...multiply by 7
----------------------------------
14x + 4y = 1270 (result of multiplying by 2)
-14x + 49y = 6097 (result of multiplying by 7)
--------------------------------add
53y = 7367
y = 7367/53
y = 139
7x + 2y = 635
7x + 2(139) = 635
7x + 278 = 635
7x = 635 - 278
7x = 357
x = 357/7
x = 51
solution : x = 51 and y = 139 or (51,139)
Answer:
I think it is 0 srry if I’m wrong
Step-by-step explanation:
The number of real solution of the system y = 
and y = 3x - 2 is zero
The system of equations are
y =
y = 3x - 2
Then the equation will be
= 3x - 2
Move 3x - 2 to the left hand side of the equation
- 3x + 2 = 0
Find the value of 
- 4ac
Here value of a = 3
The value of b = -3
The value of c = 2
Substitute the values in the expression
= 
- 4×3×2
= 9 - 24
= -15
Here the value of - 4ac is -15
Therefore there is no real valued solution
Hence, the number of real solution of the system y = and y = 3x - 2 is zero

Hello!
To find how much less Marvin pays per liter using his loyalty card, we can subtract the discounted value from the original value.
1.679 - 1.439 = 0.24
Therefore, Melvin pays 0.24 dollars less per liter using his loyalty card.
