Which ordered pairs are solutions to the inequailty 2x + y > -4 Select each correct answer

A) (-1, -1)
B) (5, -12)
C) (-3, 0)
D) (0, 1)
E) (4, -12)

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
