Answer:
15$+35$+8.25$=58.25
so the total of bill for Jana's new clothes is 58.25
Answer:
100x+150y≤1200
y≤8-2x/3
slope = -2/3
y-intercept = (0,8)
Step-by-step explanation:
I graphed it on my calculator but I'm not really sure how to explain it beyond just sharing a screenshot of the image
I hope that helps
The solution to the given simultaneous equation; x + 2y = -4, 2x + 5y = 1 using substitution method is x = -22 and y = 9
<h3>Simultaneous equation</h3>
x + 2y = -4
2x + 5y = 1
Using Substitution method
From equation (1)
x = -4 - 2y
Substitute x = -4 - 2y into equation (2)
2x + 5y = 1
2(-4 - 2y) + 5y = 1
-8 - 4y + 5y = 1
- 4y + 5y = 1 + 8
y = 9
Substitute y = 9 into
x + 2y = -4
x + 2(9) = -4
x + 18 = -4
x = -4 - 18
x = - 22
Therefore, the solution to the given simultaneous equation; x + 2y = -4, 2x + 5y = 1 using substitution method is x = -22 and y = 9

Answer:
13.0 is the answer
Step-by-step explanation:
Two points are given (-3,9) and (4,-2)
Distance = √[(-3-4)^2 + (9 + 2)^2]
= √(49 + 121)
=√170
= 13.0
