From the table of values you can see the each y value is 3 times the x value.
This would be the slope of the line of graphed.
The equation is y = 3x
Answer:
concave polygones
Step-by-step explanation:
Answer:
C. The product of 12 and √17
Step-by-step explanation:
Because it gives a number that isn't a repeating or terminating decimal.
Answer:
<em>y = -2x - 4</em>
Step-by-step explanation:
<em>y + 1 = -2x - 3</em>
<em>Subtract 1 from both sides to get the y by itself</em>
<em>y = -2x - 3 - 1</em>
<em>Simplify (Combine Like terms)</em>
<em>y = -2x - 4</em>
Answer:
- 40 popcorns and 90 pretzels sold.
============
Let the number of popcorns is x and pretzels is y.
Set up equations:
- x + y = 130
- 2.5x + 2y = 280
Solve by elimination, multiply the first equation by 2 and subtract from the second equation:
- 2.5x + 2y - 2x - 2y = 280 - 2*130
- 0.5x = 280 - 260
- 0.5x = 20
- x = 20/0.5
- x = 40
Find y:
- 40 + y = 130
- y = 130 - 40
- y = 90
