Answer:

x is equal to -3

Step-by-step explanation:

If you have a lot of problems with decimal coefficients (I know I do), you can get rid of them first. Just multiply both sides of the equation by 10:

.3x² + 1 = .1

3x² + 10x = x

Then note that each term is also divisible by x. If we factor that out, we get:

3x + 10 = 1

Which we can easily solve for x:

3x = -9

x = -3

Which value, when placed in the box, would result in a system of equations with infinitely many solutions?

Fantom [35]

Answer:

<h2>If we placed the number 10 in the box, we obtain a system of equations with infinitely many solutions.</h2>

Step-by-step explanation:

The given system is

$y=2x-5\\2y-4x=a$

It's important to know that a system with infinitely many solutions, it's a system that has the same equation, that is, both equation represent the same line, or as some textbooks say, one line is on the other one, so they have inifinitely common solutions.

Having said that, the first thing we should do here is reorder the system

$y=2x-5\\2y=4x+a$

This way, you can compare better both equations. If you look closer, observe that the second equation is double, that is, it can be obtained by multiplying a factor of 2 to the first one, that is

$y=2x-5\\2y=4x-10$

So, by multiplying such factor, we obtaine the second equation. Observe that $a$ must be equal to 10, that way the system would have infinitely solutions.

Therefore, the answer is 10.

How do i solve this equation -4p+9=-5

gregori [183]

Answer:

p = 7/2

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

-4p + 9 = -5

Step 2: Solve for p

Subtract 9 on both sides: -4p = -14
Divide -4 on both sides: p = 7/2

Step 3: Check

Plug in p into the original equation to verify it's a solution.

Substitute in p: -4(7/2) + 9 = -5
Multiply: -14 + 9 = -5
Add: -5 = -5

Here we see that -5 does indeed equal -5.

∴ p = 7/2 is the solution to the equation.
