Answer:
(1,4)
Step-by-step explanation:
Let y (upper eq) = y (lower eq)
x+3 = 3x+1
(transposing similar numbers)
3x-x = 3-1
2x = 2
then x = 1
substituting x in any of the equation, say
y = x+3
y = 1 +3
y = 4
therefore (1,4)
check again the lower equation
y = 3x + 1
y = 3(1) + 1
y = 4
therefore (1,4)
Answer:
i have no idea but if i had to guess it would be around -3.00k or -4.00k
Step-by-step explanation:
13)
-4-7/ -6 - -4
-11/ -2
5.5 is the slope of this one
14) 16-8/ 9-20
8/-11
-1.375 is your slope
Hopes you out

Answer:
No, because there isn't a pattern in the numbers. For the y you are adding one but for the x there isn't a shown pattern. Also when graphing the table, it doesn't make a straight line.
Step-by-step explanation:
For example, look at the table shown. On the x you are adding 1 and for the y you are adding 2. This makes it a function and creates a straight line
1) 2 * (10 * 7 + 7 * 1,25 + 10 * 1,25) = 2 * (70 + 8,75 + 12,5) = 2 * 91,25 = 182,5 square inches - a surface area
2) 182,5 * 0,012 = <span>$</span>2,19 - answer.
