Hi, there.

  ______

Start off by noting that 2x+5 can be either positive or negative.

First off let's solve for x, where 2x+5 is a positive.

Thus,

2x+5 < 4\\2x < -1\\x < -\dfrac{1}{2}

Now let's solve for x, where 2x+5 is a negative. But first we need to distribute -1. -2x-5.

Now solve.

-2x-5 < 4\\-2x < 9\\x < -\dfrac{9}{2}

Hope the answer - and explanation - made sense,

happy studying.

-9 < 2x < -1

-4.5 < x < -0.5

Allushta [10]

P = 300 $; r = 0.06; t = 20; n = 1

A = P ( 1 + r/n)^n*t

= 300 ( 1 + 0.06) ²⁰

= 300 ( 1.06) ²⁰

= 962.14

Mike is playing cards with his sister when he draws a card from a pack of 35 cards numbered from 1 to 35 what is the probability

1/5 because there are 7 numbers divisible by 5 from 1 to 35. 5,10, 15, 20,25,30,35, and out of those there are 35 cards, 7 out of 35 or 7/5 can be simplified to 1/5.

If log(x + y) = log 3 + ½log x + ½log y, prove that x² + y² = 7xy​
Free_Kalibri [48]

Answer:

See Explanation

Step-by-step explanation:

log(x + y) = log3 +  \frac{1}{2} logx+  \frac{1}{2} logy \\  \\ log(x + y) = log3 +    logx ^{\frac{1}{2}} +   logy ^{\frac{1}{2}}\\  \\  log(x + y) = log3 +    log(xy) ^{\frac{1}{2}} \\  \\ log(x + y) =  log[3(xy) ^{\frac{1}{2}}] \\  \\ x + y = 3(xy) ^{\frac{1}{2}} \\  \\ squaring \: both \: sides \\  {(x + y)}^{2}  =  \bigg(3(xy) ^{\frac{1}{2}} \bigg)^{2}  \\  \\  {x}^{2}  +  {y}^{2}  + 2xy = 9xy \\  \\  {x}^{2}  +  {y}^{2}  = 9xy - 2xy \\  \\   \purple{ \bold{{x}^{2}  +  {y}^{2}  = 7xy}} \\ thus \: proved
