4(5)+6(5)-10(5)=0
(5) basically means times 5. So 4 times 5 is 20. 6 times 5 is 30. 20 plus 30 is 50. 10 times 5 is also 50. 50-50 is 0.
Good Luck, hope this helps!

Solve the following system of equations. Enter the x-coordinate of the solution. Round your answer to the nearest tenth.
Sergeu [11.5K]

Answer: <u>3.7</u>

Step-by-step explanation: 3.706, but since you need it rounded to the nearest tenth its 3.7. If you put both equations on a graph, they intercept. We use the x coordinate in this intersection as the answer.

What are the solutions for x when y is equal to 0 in the quadratic function y=x^2-8x
Elena L [17]
I would use the quadratic formula for this:

  x = -b ± √b² - 4ac over 2a
  x = 8 ± √64 - 4(1)(0) over 2(1)
  x = 8 ± √64 over 2
  x = 8 <span>± 8 over 2 [simplify]
  x = 4 </span><span>± 4
     x1 = 4 + 4    x2 = 4 - 4
     x1 = 8          x2 = 0


Thus, the solutions for x would be 0 and 8.</span>

Help please. Having some trouble with this question
xeze [42]

Answer:

The answer to your question is 55 ft

Step-by-step explanation:

Data

Person's height = 5 ft

Person's shadow = 10 ft

Tree's height = ?

Tree's shadow = 110 ft

- Use the Thales' theorem to solve this problem

 Person's height / Person's shadow = Tree's height / Tree's shadow

- Substitution

                     5 / 10 = x / 110

-Solve for x

                     x = 5 (110) / 10

-Simplification

                     x = 550 / 10

-Result

                     x = 55 ft

-Conclusion

The tree is 55 ft height
