Answer:
y=-5x+5
Step-by-step explanation:
y=mx+b
m = slope which is 5 going down, so -5
b = y intercept which is 5
$19.20 would be the total amount
An "obtuse" angle is an angle that's bigger than 90 degrees.
So two obtuse angles would add up to more than 180 degrees.
But the three angles inside a triangle always add up to exactly 180 degrees.
So two of them can't be obtuse.
Assume the price of one pizza is x and the price of one soda is y.
1) x+2y=15.95
2) 3x+5y=45.90
multiply equation (1) by -3 and add the result to equation (2).
y=$1.95 (one soda)
Replace y in the first equation: x=$12.05
