Find the value of X.

Nezavi [6.7K]

Answer:

A. 12

Step-by-step explanation:

TU and CV are two chords of the circle that intersects at point w.

Thus,

$x*3 = 9*4$ (two intersecting chords theorem)

Solve for x

$3x = 36$

Divide both sides by 3

$\frac{3x}{3} = \frac{36}{3}$

$x = 12$

If p(a) = 0.50, p(b) = 0.60, and p(a intersection

bogdanovich [222]

Use the identity P(A ∪ B) = P(A)+P(B)-P(A ∩ B)

P(A)=0.50
P(B)=0.60
P(A ∪ B) = 0.30
=>
P(A ∪ B) = P(A)+P(B)-P(A ∩ B)
=(0.50+0.60)-0.30
=0.80

2x+y=8;y i have no idea what theyre asking. Its solve each equation for the indicated variable

xxTIMURxx [149]

If solving for y:

→ 2x + y = 8
→ Take away 2x from both sides
→ y = 8 - 2x

If solving for x:

→ 2x + y = 8
→ Take away y from both sides
→ 2x = 8 - y
→ Divide both sides by 2
→ x = $\frac{8-y}{2}$
