Step-by-step explanation:
x=y+7
3x+2y=6
so wherever you see X you but y+7
3(y+7)+2y=6
3y+21+2y=6
group like terms
3y+2y=6-21
5y=-15
divide by 5
y=-3
to find x sub the y value in the equation
x=y+7
x=-3+7
x=4
(9,13) would be another point that the line passes through.
Answer:
1742 inches squared
Step-by-step explanation:
Surface Area = 2×(20×21 + 20×11 + 21×11) = 1742 inches2
The range is 8 and if you needed help finding the median it is 2 I think
Btw remember that median means middle, range means the difference between the highest and lowest number, the mode means what number have the most, and the mean is the total of all the values and then divide by the number of values :)
