Answer:

There is not enough information to find a solution. The work to find it if more variable are filled is below. You can also solve the problem by inputting these equations as solutions.

Step-by-step explanation:

(x^(2)+a)(x^(2)-b)=0

You can find x by taking the square root of both sides

√(-a), -√(-a), √b, -√b

You can find a by -x^(2)

You can find b by x^(2)

Does anyone know how to do thesubstitution method?

Hi!

<h3>How do we use the substitution method?</h3>

To solve using the substitution method, we first want to isolate any of the variables from one of two equations, and then you take the value of that and plug it into the other equation.

<h3>Given:</h3><h3> $y=4x-10$ </h3>

$y=-3x+4$

Normally, our step one would be to pick a variable and isolate it, but it looks like we already have the y-value in both equations isolated! So our step one is already done!

Plug the isolated variable into the other equation.

We will use the value of y in the first one, and plug it into the second.

The value of y is "4x - 10", so we will change "y" in the second equation to "4x - 10", like so:

$4x-10=-3x+4$

<h3>Step Three:</h3>

Algebra!

You should be familiar with how to solve equations.

So:

$4x-10=-3x+4$

Add 10 to both sides:

$4x=-3x+14$

Add 3x to both sides:

$7x=14$

Divide both sides by 7:

$x=2$

Now, take the x value and plug it into one of the other equations and solve for y.

$y=4(2)-10$

$y=8-10$

$y=-2$

Therefore, our answer is (2, -2).

The coordinate plane below represents a city.

Answer:

Part A) The system of inequalities is

$x\geq2$ and $y\geq2$

Part B) In the procedure

Part C) The schools that Natalie is allowed to attend are A,B and D

Step-by-step explanation:

Part A: Using the graph above, create a system of inequalities that only contain points C and F in the overlapping shaded regions

we have

Points C(2,2), F(3,4)

The system of inequalities could be

$x\geq2$ -----> inequality A

The solution of the inequality A is the shaded area at the right of the solid line x=2

$y\geq2$ -----> inequality B

The solution of the inequality B is the shaded area above of the solid line y=2

see the attached figure N 1

Part B: Explain how to verify that the points C and F are solutions to the system of inequalities created in Part A

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities

Verify point C

C(2,2)

<em>Inequality A</em>

$x\geq2$ -----> $2\geq2$ ----> is true

<em>Inequality B</em>

$y\geq2$ ------> $2\geq2$ ----> is true

therefore

Point C is a solution of the system of inequalities

Verify point D

F(3,4)

Inequality A

$x\geq2$ -----> $3\geq2$ ----> is true

Inequality B

$y\geq2$ ------> $4\geq2$ ----> is true

therefore

Point D is a solution of the system of inequalities

Part C: Natalie can only attend a school in her designated zone. Natalie's zone is defined by y < −2x + 2. Explain how you can identify the schools that Natalie is allowed to attend.

we have

$y < -2x+2$

The solution of the inequality is the shaded area below the dotted line $y=-2x+2$

The y-intercept of the dotted line is the point (0,2)

The x-intercept of the dotted line is the point (1,0)

To graph the inequality, plot the intercepts and shade the area below the dotted line

see the attached figure N 2

therefore

The schools that Natalie is allowed to attend are A,B and D

Is number 3 is correct and please help with number 4

adoni [48]

No, you forgot to multiply by 5 ml.

250/250 * 5 = 5 ml by mouth three times a day

#4 has to be in correct units. you cannot divide grams by milligrams.

I would change dose to milligrams 0.1g * 1000 = 100 mg dose. Quantity is 1 capsule

100/100 * 1 = 1 pill by mouth twice daily
