Y^2-2y+1=x+5<br><br> Make y the theme of the formula in the equation

Tanzania [10]

Answer: y = 1 +/- $\sqrt{x+5}$

<u>Step-by-step explanation:</u>

y² - 2y + 1 = x + 5

(y - 1)² = x + 5

$\sqrt{(y-1)^{2}} = \sqrt{x+5}$

y - 1 = +/- $\sqrt{x+5}$

y = 1 +/- $\sqrt{x+5}$

A number is 5 more than 3 times another number. The sum of the two numbers is 33. As an equation, this is written x + 3x + 5 = 3

Cloud [144]

Answer:

x=7, so the smaller number is 7 and the larger number is 21.

Step-by-step explanation:

x=3x+5=33

Let x=3:

(3)+3(3)+5=3+9+5=17, not 33, so x is not 3

Let x=5:

(5)+3(5)+5=5+15+5=25, not 33, so x is not 5

Let x=7:

(7)+3(7)+5=7+21+5=33, so x=7

Let x=9:

(9)+3(9)+5=9+27+5=41, not 33, so x is not 9

Therefore x=7. Because x represents the smaller number, and the larger number is 3 times the smaller number, the smaller number is 7 and the larger number is 3(7)=21.
