Answer:

x = 43

Step-by-step explanation:

Since these angles are inside a right angle, we know their sums are complementary (they add up to 90°.)

x + x + 4 = 90

2x + 4 = 90 | Combine x's

2x = 86 | Subtract 4 from both sides

x = 43 | Divide both sides by 2

50.For the direct variation such that when y = 2 then x = 3, find the constant of variation ( k ) and then find the value of y w
tamaranim1 [39]

Step-by-step explanation:

Since it's a direct variation

y = kx

where k is the constant of proportionality

To find the value of y when x = –0.5 we must first find the relationship between the variables

When

x = 3

y = 2

2 = 3k

Divide both sides by 3

k =  \frac{3}{2}

So the formula for the variation is

<h3>y =  \frac{3}{2} x</h3>

When x = - 0.5 or - 1/2

y =  \frac{3}{2} ( -  \frac{1}{2} )

We have the final answer as

<h2>y =  -  \frac{3}{4}</h2>

Hope this helps you
