The slope of -5x + y = 56 is 5
the slope of x + y = -4 is -1
Answer:
3a. yes
3b. y= 75x
3c. 600 mi
3d. 10 inches
Step-by-step explanation:
3a: if you divide the y by the x, you'd get 75 everytime, meaning it's proportional.
3b: y would equal the amount of inches multiplied by 75, so y=75x
3c: you can use the equation and substitute the x for 8, so y=75(8), giving you 600 miles
3d: you can also use the equation in reverse, if the actual miles is 750, then this is your y, so it would look like 750=75x and to solve you'd divide, 750/75, giving you 10 inches

Answer:
0<y<8
Step-by-step explanation:
So, as you can see by the graph, the y axis has a plot as low as 0. soo it would be 0. Then the highest plot is marked as high as 8. Therefore its 0<y<8.
Had a hard time wording it so i hope you understand.
Answer:
d. $19.20
Step-by-step explanation:
Let C = original cost of pizza
24 = .05C + .20C + C
= 1.25C
C = 19.20
