Simplify the question so it uses x's and y's or any two letters instead of egg/juice (not necessary)
egg = x
juice = y
x + 2y = 2.30
2x + y = 3.40
Make x the subject
x = 2.30 - 2y
Add pervious step to 2x + y = 3.40 then solve for y
2(2.30 - 2y) + y = 3.40
4.60 - 4y + y = 3.40
4.60 - 3y = 3.40
-3y = -1.20
3y = 1.20
y = 0.40
Now solve for x
x + 2y = 2.30
x + 2(0.40) = 2.30
x + 0.80 = 2.30
x = 1.50
One egg costs $1.50
One juice costs $0.40
Therefore, one egg plus one juice costs $1.90

Step-by-step explanation:
no explination
Your answer is D because rhombus because you can look at examples that are rhombus like the trapezoid and the diamond
Answer:
Undefined
Step-by-step explanation:
☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.
Slope of the line
Thus, the slope of the line is undefined.
(Since 2 cannot be divided by zero)
Notice that the two coordinates have the same y- coordinate of -4. This means that the line is a vertical line. Vertical lines have undefined slopes.
