Answer:

x=7

Step-by-step explanation:

This is a right triangle, we can use sin , cos, and tan

tan theta = opposite side/ adjacent

tan 45 = 7/x

Multiply each side by x

x tan 45 = 7/x *x

x tan 45 =7

Divide each side by 45

x tan 45 / tan 45 = 7/ tan 45

x = 7 / tan 45

x =7

Evaluate the sum or explain why it diverges: Sigma^infinity_k = 3(-3/2)^k
LenaWriter [7]

Answer:

Step-by-step explanation:

Remember that in the geometric serie if | r | < 1 the serie converges and if | r | ≥1 the serie diverges.

I suppose that the serie starts at 0, so using the geometric serie with r = | \frac{-3}{2} | > 1 the serie diverges.

Solve for y.<br><br> 2y - x = <br> 3<br> 4<br> (-y + 1)
Mars2501 [29]

2y-x=3/4(-y+1)first distribute

2y-x=-3/4y+3/4 get the y on one side

2y-x+3/4y=3/4 add 3/4y to both sides

2y+3/4y=3/4+x add x to both sides

11/4y=3/4+x now divide by 11/4 (both sides)

y=3/11+4/11x

y=3+4x/11

choice c is the answer
