The expression
means "all the numbers stricktly greater than -4"
Since the number line is oriented with positive direction going to the right, a number is greater than another if its sits to its right.
So, we want all the numbers to the right of -4, excluded -4 itself.
So, the answer is D.
x = 15°
The angle of a straight line is 180°.
37 + 9x + 8 = 180
9x + 45 = 180
9x = 135
x = 15°
If

is conservative, then there is a scalar function

such that

Setting the first components equal to one another, we can integrate both sides to find

Differentiating both sides with respect to

gives



so that

By the fundamental theorem of calculus, we have that
Answer:
f(7) = 16
Step-by-step explanation:
substitute x = 7 into f(x) , that is
f(7) = 3(7) - 5 = 21 - 5 = 16
