Add 4 to both sides

-10 + 4 = 2a

Simplify -10 + 4 to -6

-6 = 2a

Divide both sides by 2

-6/2 = a

Simplify 6/2 to 3

-3 = a

Switch sides

Find the value of x. Round your answer to the nearest tenth.

skad [1K]

Answer:

x = 9.7

Step-by-step explanation:

Reference angle (θ) = 68°

Opposite = 24

Adjacent = x

Apply, the trigonometric function, TOA which is:

$tan (/theta) = \frac{Opp}{Adj}$

Plug in the values

$tan 68 = \frac{24}{x}$

Multiply both sides by x

$x*tan 68 = 24$

Divide both sides by tan 68

$x = \frac{24}{tan 68}$

x = 9.69662942

x = 9.7 (nearest tenth)

Which order pair could be removed so that the set of ordered pairs is a function (4,-2) (-3,2) (3,4) (1,1)

Masja [62]

<span> (4,-2) (-3,2) (3,4) (1,1)
In reality, it is already a function, because for every x only one corresponding value of y.
We do not see any repeating values of x, so this set is already function. We do not have to remove anything.</span>
