Answer
x=-2 and y=-3
Step-by-step explanation:
Step: Solvey=5x+7for y:
Step: Substitute5x+7 for y in 3x+y=−9:
3x+y=−9
3x+5x+7=−9
8x+7=−9(Simplify both sides of the equation)
8x+7+−7=−9+−7(Add -7 to both sides)
8x=−16
8x/8=−16/8
(Divide both sides by 8)
x=−2
Step: Substitute−2 for x in y=5x+7:
y=5x+7
y=(5)(−2)+7
y=−3(Simplify both sides of the equation)
Answer:
continental shelf
Step-by-step explanation:
The continental shelf extends from the edge of the continent into the sea. The shelf extends from the shoreline into the continental slope.

It subjected to a high tidal change during a single day.
Answer: 7/12
Step-by-step explanation: To add these two fractions together, we start by finding their common denominator.
The common denominator for 3 and 4 will be the least common multiple of 3 and 4 which is 12. So we multiply the top and bottom of our first fraction by 4 and the top and bottom of our second fraction by 3. That gives us 4/12 + 3/12 which simplifies to 7/12.
Therefore, 1/3 + 1/4 = 7/12 which is in lowest terms.
