What is the solution of sqrtx^2+49 = x+5?​

Mathematics
1 answer:
Lady_Fox [76]3 years ago
5 0

Answer:

<h2>x = 12/5</h2>

Step-by-step explanation:

√x² + 49 = x + 5

Square both sides

(√x² + 49)² = ( x + 5)²

x² + 49 = x² + 10x + 25

Simplify

10x = 49 - 25

10x = 24

Divide both sides by 10

<h3>x = 12/5</h3>

Hope this helps you

Answer:

(16/3,-4)

Step-by-step explanation:

  1. y=-3/4x & y=3/2x -12
  2. then solve for x which means -3/4x=3/2x-12
  3. then the value of x=16/3
  4. put the x value in one equation
  5. y=3/4(16/3)
  6. then the value of y=-4

Errors in an experimental transmission channel are found when thetransmission is checked by a certifier that detects missing pul
irina1246 [14]

Answer:

As shown below

Step-by-step explanation:

Given that when X denotes the errors in an experimental transmission channel, when checked by a certifier that detects missing pulses. follows the cumulative density function as given below:

F(x) = 0, 0

(a) P(X \leq  4) =F(4) = 0.9\\(b) P(X > 7)=1-F(8) = 0\\(c) P(X \leq  5)=F(6) = 0.9 \\(d) P(X> 4)=1-F(4)=1-0.9=0.1 \\(e) P(X \leq  2)=F(3) = 0.7

I need help pleaseeee!!!!! I don’t understand
olganol [36]

Answer:

a. x = 5, m∠FGH = 22°

b. m∠HGI = 22°

c.  m∠FGI = 44°

Step-by-step explanation:

Since GH bisects FGI this means it divides the angle in two equal parts.

a. solving for x means equating them:

5x-3 = 6x-8 =>

5x - 6x = 3 - 8 =>

x = 5.

Both m∠FGH and m∠HGI are 5*5-3 = 22°

c. Add both angles: m∠FGH + m∠HGI = 44°

Which expression is equivalent to 5(4f+3)-2f
Ierofanga [76]

Answer:

f = 5/6

Step-by-step explanation:

5(4f + 3) - 2f

= 20f + 15 - 2f

= 18f + 15

18f = 15

f = 15/18

f = 5/6
