Tell whether the angles are complementary or supplementary. Then find the value of x

Answer:

Complementary, x=60.

Step-by-step explanation:

The angles are complementary because they add up to 90 degrees, opposing supplementary angles, which add up to 180 degrees. To find x, we need to form an equation to represent the problem. We know the two angles add up to 90 degrees, so we can use that to make the equation.

(x-30)+x=90  Simplify.

x-30+x=90

2x-30=90      Add 30 to both sides.

  +30 +30

2x=120          Divide both sides by 2.

x=60

We can also find the value of the angles by plugging in x.

Angle 1: (x-30)

             (60-30)

             30 degrees

Angle 2: x

              60 degrees

(You can also notice that the two angles add up to 90 degrees, which is another way of telling that the angles are complementary.)

Which expression is equivalent to 5x+10y-15

Matilda has been studying exponential functions in her algebra class and has started to notice a pattern.

For some exponential functions, when she plugs in larger and larger numbers, she gets larger and larger numbers. For others, she gets smaller and smaller numbers. And for some, plugging in larger and larger numbers actually gets her closer and closer to one number.

Which of the following exponential functions get closer and closer to one value as you plug-in larger and larger values for x?

Select one:
A. f(x)=(34)^(x)+9
B. f(x)=0.45(1.9)^(x)
C. f(x)=(65)^(x)−6
D. f(x)=−7(2)^(x)
