Your problem did not have an operator between the x and 1 so I did it as subtraction and addition. There was no answer choice -3 so D x=-9 is the answer
What's the answer to the question I really need help

Answer:
The prices for a calzone and for soda as an ordered pair (c,s) is (5,1)
Step-by-step explanation:
Let c be the prize of calazone
Let s be the prize of soda
She buys two calzones and three sodas she pays $13
So, 2c+3s=13
She buys three calzones and two sodas she pays $17
So, 3c+2s=17
Plot the equations on graph
2c+3s=13 --- Green
3c+2s=17 --- Blue
Intersection point will give the intersection point
So,(c,s)=(5,1)
So, Option c is correct
The prices for a calzone and for soda as an ordered pair (c,s) is (5,1)
Answer:
Question 4: Which equation is parallel to the above equation and passes through the point (35, 30)
is the correct answer, I found this by inputting the x and y value of the coordinate (35, 30) onto the equation and solving for y-intercept since the slope of all equations is the same (since it's traveling parallel)
so the equation would be
Question 5: Which equation is perpendicular to the above equation and passes through the point (35, 30)
is the correct answer, I found this using the same method as before, input coordinate values into the equation and solve for the y-intercept (The only thing changed from the last answer is the opposite reciprocal slope).
so the equation would be
