An odd number multiplied by an odd number is an odd number. Therefore an odd number squared is also always an odd number.

The point (-2,3) is the solution to a system of two linear equations. Which of the following can be one of the

Fynjy0 [20]

Answer:

We conclude that The point (-2, 3) satisfies the equation y = -x+1.

Hence, option B i.e. y = -x+1 is one of the equations of a system of two linear equations.

Step-by-step explanation:

Given

The point (-2, 3)

<u>Checking option A</u>

Given the equation

y = 3x-2

substitute x = -2 and y = 3

3 = 3(-2) - 2

3 = -6 - 2

3 = -8

FALSE!

L.H.S ≠ R.H.S

Thus,

The point (-2, 3) does not satisfy the equation y = 3x-2.

<u>Checking option B</u>

Given the equation

y = -x+1

substitute x = -2 and y = 3

3 = -(-2)+1

3 = 2+1

3 = 3

TRUE!

L.H.S = R.H.S

Thus,

The point (-2, 3) satisfies the equation y = -x+1.

<u>Checking option C</u>

Given the equation

y=x-1

substitute x = -2 and y = 3

3 = -2-1

3 = -3

FALSE!

L.H.S ≠ R.H.S

Thus,

The point (-2, 3) does not satisfy the equation y=x-1.

<u>Checking option D</u>

Given the equation

y=2x+3

substitute x = -2 and y = 3

3 = 2(-2)+3

3 = -4+3

3 = -1

FALSE!

L.H.S ≠ R.H.S

Thus,

The point (-2, 3) does not satisfy the equation y=2x+3.

Conclusion:

Thus, we conclude that The point (-2, 3) satisfies the equation y = -x+1.

Hence, option B i.e. y = -x+1 is one of the equations of a system of two linear equations.

9.4 × 10-4 =<br><br> 0.00094<br> 0.0094<br> 94,000<br> 940,000

Alexus [3.1K]

Answer:

0.00094

Step-by-step explanation:

Scientific Notation is a shortened form of writing a number using exponents. It has the following rules:

Use a positive exponent for large numbers greater than 1.
Use a negative exponent for small numbers less than 1.
Always write the first number as a value between 0 and 9.

9.4 x 10^-4 has a negative exponent and will be a number smaller than 1. This means 0.00094 and 0.0094 are options. Now count from the decimal in each to the space between 9 and 4. In the first it is 4. In the second it is 3. Since the exponent is -4, this means 0.00094 is the solution.

Write the following inequality in slope intercept form<br> -6x+3y>-45

QveST [7]

Slope intercept form is y = mx + c.

<em>(where m is the slope, and c is the intercept - hence slope intercept form)</em>

So all you have to do is rearrange the inequality to have y by itself.

-6x + 3y > - 45 <em>(add 6x to both sides)</em>

3y > - 45 + 6x <em>(divide both sides by 3)</em>

y > - 15 + 2x <em>(put the 2x infront of the - 15) </em>

y > 2x - 15

- - - - - - - - - - - - - - - - - - - - - - -

Answer:

y > 2x - 15

- - - - - - - - - - - - - - - - - - - - - - -
