The answer is A because you would do 79 x 0.05 which equals 3.95 . So you subtract 3.95 from 79 which is 75.05 minus 50 equal to 25.05

Answer:

The answer is A

Step-by-step explanation:

100% = $79

1% = $0.79

100% - 5% = 95% (total amount need to pay)

95% = $75.05

$75.05 - $50 = $25.05 (remaining amount need to be paid)

Find a linear second-order differential equation f(x, y, y', y'') = 0 for which y = c1x + c2x3 is a two-parameter family of solu

Alisiya [41]

Let $y=C_1x+C_2x^3=C_1y_1+C_2y_2$ . Then $y_1$ and $y_2$ are two fundamental, linearly independent solution that satisfy

$f(x,y_1,{y_1}',{y_1}'')=0$
$f(x,y_2,{y_2}',{y_2}'')=0$

Note that ${y_1}'=1$ , so that $x{y_1}'-y_1=0$ . Adding $y''$ doesn't change this, since ${y_1}''=0$ .

So if we suppose

$f(x,y,y',y'')=y''+xy'-y=0$

then substituting $y=y_2$ would give

$6x+x(3x^2)-x^3=6x+2x^3\neq0$

To make sure everything cancels out, multiply the second degree term by $-\dfrac{x^2}3$ , so that

$f(x,y,y',y'')=-\dfrac{x^2}3y''+xy'-y$

Then if $y=y_1+y_2$ , we get

$-\dfrac{x^2}3(0+6x)+x(1+3x^2)-(x+x^3)=-2x^3+x+3x^3-x-x^3=0$

as desired. So one possible ODE would be

$-\dfrac{x^2}3y''+xy'-y=0\iff x^2y''-3xy'+3y=0$

(See "Euler-Cauchy equation" for more info)

the area is 41.6cm which is 1foot 4 3/8 inches.

So 6in + 6in + 6in = 1ft 6in, which will be enough to cover the floor.

When I think of a number, double it, then add 7, I get 25. What number did I think of? ( Hint: Let the number be x)o

vivado [14]

Hey there!

The answer is $9$

We will start by forming an equation to solve this.

So we are starting with a number, $x$ , then doubling it and adding $7$ , which gives us 25.

So:

$2x+7=25$

Now we solve this equation:

$2x+7=25$

$2x=18$

$x=9$

Have a super awesome day!

Five times the sum of a number and 7 equals 3

miv72 [106K]

The answer or number that you are looking for is -6.4. You can get this by dividing 3 by 5 which is equal to 0.6. Next you would subtract 7 to reverse the act of having added it. This will give you -6.4 which is what you are looking for.
