Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line. When x increases, y increases twice as fast, so we need 2x. When x is 0, y is already 1.
Answer: <em>x</em>∈(5,∞)
Step-by-step explanation:
x-7>-2=(x-7)+7>-2+7=<em>x</em>∈(5,∞)
To solve we need to group all the variables on one side, and all the constants on the other side.
Answer:
f(x) crosses the x-axis, then
f(x)=(x+4)^6(x+7)^5 = 0
=> x+4 =0 or x+7=0
=> x =-4 or x = -7
