Isolate y
2x + y = 5
y = -2x + 5
The slope of the new line should be -2, since parallel lines have same slope.
Since y-int. is 4:
y = -2x + 4 is the new equation.
13 and 14 squared all round up to 200.
13^2=169 rounded to the nearest hundred is 200
14^2=196 rounded to the nearest hundred is 200
We can't go any lower than 13 because 12^2=144, and 144 rounds to 100. We also can't go any higher than 15 because 15^2=225, and 225 rounds down to 200, not up (Thanks Irspow).

Answer: $1,624
Step-by-step explanation:
The amount after x-years is given as :
9 + 50x + 1000
Since x represents number of years , this means that after 6 years , the amount will be :
9( ) + 50(6) + 1000
⇒9(36) + 300 + 1000
⇒324 + 300 + 1000 =
Therefore, the amount after 6 years will be $1,624
D).
We want x to be greater than or equal to 4.3. The closed circle tells us that it can be equal to 4.3. The ray to the right tells us that we are looking for numbers larger than 4.3.
