Answer:
the price for one pretzel was $1.75
Step-by-step explanation:
d for drinks
p for pretzel
3d + 3p = 9
3d = 9 -3p
d = 3 - p
replace d = 3 - 9 into 4d + 2p = 8.5
4d + 2p = 8.5
4(3 - p) + 2p = 8.5
12 - 4p + 2p = 8.5
-2p = 8.5 - 12
-2p = -3.5
p = 1.75
Answer:
The slope-intercept form of the given equation is,

Step-by-step explanation:
The given equation of the line is,
- 4<em>x</em> + 7<em>y</em> = - 14
Adding '4<em>x</em>' on both sides of the above equation, we get
- 4<em>x</em> + 7<em>y</em> + 4<em>x</em> = - 14 + 4<em>x</em>
⇒ 7<em>y</em> = 4<em>x</em> - 14
Now, dividing both sides of the above equation by '7', we get
7<em>y</em> ÷ 7 = (4<em>x</em> - 14) ÷ 7


This is the required equation of the line in slope-intercept form.
I think it's 11.66 if you use the pythagorean theorem

Option ( C ) is the correct answer.
