How do you solve a radical equation? What are the steps in doing so?
solniwko [45]

Radical Equation:

1. Isolate the radical expression.

2. Square both sides of the equation: If x = y then x2 = y2.

3. Once the radical is removed, solve for the unknown.

4. Check all answers.

Another way of saying it:

1. Isolate the radical expression involving the variable. ...

2. Raise both sides of the equation to the index of the radical.

3. If there is still a radical equation, repeat steps 1 and 2; otherwise, solve the resulting equation and check the answer in the original equation.

Helene invested a total of $1,000 in two simple-interest bank accounts. One account paid 8% annual interest; the other paid 9% a
Lelu [443]

Answer: -600 and 1600 were invested into the two accounts.

Step-by-step explanation:

x = amount invested in the first account.

y = amount invested in the second account.

You start off with this equation

x + y = 1000

0.08x + 0.09y=86

Subtract both sides by y.

x=1000-y

Subsitude 1000 - x for x for the second equation.

0.08(1000-y)+0.09y=$86

Use the distributive property to solve for y.

80-0.08y+0.09y=86

80-0.01y=86

6=-0.01y

=-600

Subsitude -600 for y in the first equation and solve for x.

x-600=1000

x=1600

-600 and 1600 were invested into the two accounts.

Hmmmm, it's either B or C, but I think B is closer related to a genre, so I think the answer is C, it has to do with the story's settings! :)

Fingers crossed that I helped!

If the line passing through the points (a, 1) and (−2, 6) is parallel to the line passing through the points (−12, 9) and (a + 2
iren2701 [21]

\frac{6 - 1}{ - 2 - a}  =  \frac{9 - 1}{ - 12 - a - 2}  \\  \frac{5}{ - 2 - a}  =  \frac{8}{ - 14 - a}  \\ 16 + 8a = 70 + 5a \\ 3a = 54 >  > a = 18

The sum of 2 numbers is 44 the smaller number is 16 less than the larger number what are the numbers
Anon25 [30]
X=27 and y=11
if you let each number equal x and y we know the sum is 38 so x+y=38
and the smaller is 16 less than the larger
. so if we say the smaller number is 7 then x-16=y
these can be solved as a simultaneous equation. x+(x-16)=38
2x-16=38
2x=54
x=27
(27)-16=y
y=11
so the answer is x=27 y=11
