Answer:
y = 4x - 3
Explanation:
4x – y + 6 = 9 Subtract 6 from each side
4x – y = 3 Subtract 4x rom each side
-y = -4x + 3 Multiply each side by -1
y = 4x - 3
As the amount is $100 dollars, you will have to find what 35% of this is. The best way to do this is to divide both 100 and 35 by ten, giving you ten and 3.5. AS 10 is 10% of 100, you should then multiply then, by three and half, therefore, giving you 35- meaning the discount is $35 dollars. Hope this helps
Answer:
20
Step-by-step explanation:
F (-7) = -6x -22
F (-7) = -6 (-7) - 22
F (-7) = 42- 22
F (-7) = 20

Answer:
4 units
Step-by-step explanation:
Create an equation where w is the width of the rectangle
Use the area formula, A = lw.
Since the length is the sum of the width and 1, it can be represented by w + 1
Plug in this and the area into the formula, and solve for w
A = lw
20 = (w + 1)(w)
20 = w² + w
w² + w - 20
(w + 5)(w - 4)
Solve for w:
w + 5 = 0
w = -5
w - 4 = 0
w = 4
Since the width cannot be negative, the answer must be 4.
So, the width of the rectangle is 4 units.
