Match each expression to its equivalent expression.

Galina-37 [17]

Answer:

white 1: black 3

white 2: black 1

white 3: black 2

Step-by-step explanation:

white 1: the denominator for the x values so it becomes 1-2=-1 which becomes -1/3x +1/4

White 2: same case as the first so we add 1+2=3 3/3=1 so that makes it x+1/4

white 3: there is only one x values that has 4 as the denominator therefore that makes the answer 3/4x+1/3

Find the measure of the missing angles in the triangle below round your answer to the nearest degree

navik [9.2K]

Answer:

a. 40°

b. 21°

Step-by-step explanation:

a. Reference angle = θ

Opposite = 5

Adjacent = 6

Apply TOA:

$Tan (\theta) = \frac{Opp}{Adj}$

$Tan (\theta) = \frac{5}{6}$

$\theta = Tan^{-1}(\frac{5}{6})$

$\theta = 40$ (nearest degree)

b. Reference angle = x

Opposite = 5

Hypotenuse = 14

Apply SOH:

$Sin (x) = \frac{Opp}{Hyp}$

$Sin (x) = \frac{5}{14}$

$x = Sin^{-1}(\frac{5}{14})$

$x = 21$ (nearest degree)

Find the number of pairs (a,b) of integers such that<br> a+2/a+5=b/3

Viktor [21]

Answer:

Step-by-step explanation:

The expression can be rearranged to ...

b = 3 -9/(a+5)

In order for b to be an integer, (a+5) must be an integer divisor of 9. There are exactly 6 of those: ±1, ±3, ±9.

The attached table shows the values (a, b) = (x₁, f(x₁)).
