I need help with number 4!
lesya692 [45]

Answer:

x = -8, y = 6

Step-by-step explanation:

x + 2y = 4 ------(1)

x + y = - 2

y = - x - 2 ----------(2)

Substitute y in (1)

x + 2(- x - 2) = 4

x - 2x - 4 = 4

- x = 4 + 4

x = -8

Substitute x in (2)

y = - (- 8) - 2 = 8 - 2 = 6

Liz needs to keep no less than $500 in her checking account to avoid fees. She had $524.75 before writing a check for $65.99. Ho
geniusboy [140]

Answer: $41.24

Step-by-step explanation: In order to figure out how much she is away from 500 we need to first subtract the 65.99.

524.75 - 65.99 = 458.76

Then find the difference from 500 by subtracting again.

500 - 458.76 = 41.24

41.24 is the amount she needs to deposit in order to avoid a fee.

What is PA <br> Enter your answer in the box
SSSSS [86.1K]

Answer:

3

Step-by-step explanation:

P is the in-center

⇒PA=PE=PD because they are in-radius of the in-circle

We know that, tangent segments drawn from a point outside the circle are always equal in length

⇒DK=EK=7.2

In right triangle PKE,

using Pythagoras' Theorem : PK^{2}=PE^{2}+KE^{2}

⇒PE^{2}=PK^{2}-KE^{2}

⇒PE=\sqrt{PK^{2}-KE^{2} }

⇒PE^{2}=\sqrt{7.8^{2}-7.2^{2}} }

⇒PE=3

Therefore, PA=3
