Answer:

20 inches

Step-by-step explanation:

If that's centimeters on the x-axis and inches in the y-axis, then the slope is 2/5 and the y-intercept is 0.

y=\frac{2}{5}x

The slope of 2/5 in this context means 2 inches per 5 centimeters. Then, either by solving the equation or by graphing the line, you can determine that there are about 20 inches in 50 centimeters.

1. If you are asked to use elimination to solve for x", what do you need to multiply the bottom equation by to eliminate "y?
hram777 [196]

Answer:

-5

Step-by-step explanation:

There is different ways to solve methods of elimination but if you wanted to cancel y out you would multiply by the opposite sign....for example

7x + 5y = 19

-5 (2x + y = 19) ---> -10x -5y = 95

this would cancel out your y to solve for x so you can plug it back in and solve! hope this helps!!!

The required number will be 16

the expression will be like :

  • 9 {x}^{2}  + 24x + 16

  • (3x) {}^{2}  + (2 \times 3x \times 4) + (4) {}^{2}

  • (3x + 4) {}^{2}

hope it helps you cap !!

Organize the following polynomial expressions from least to greatest based on their degree: x 2xyz 9x3y2 18x2 5ab − 6y 4x4 3x2 −
Advocard [28]

The order will be IV, III, I, and II.

<h2>Polynomial</h2>

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Given

 I.  x + 2xyz

II.  9x³y²

III.  18x² + 5ab - 6y

IV. 4\rm x^{4} + 3x² - x - 4

<h3>To find </h3>

The polynomial expressions from least to greatest are based on their degree.

<h3>How to organize?</h3>

4\rm x^{4} + 3x² - x - 4 is a biquadratic ploynolmial.

18x² + 5ab - 6y is a cubic polynomial.

x + 2xyz is a quadratic polynomial.

9x³y² is a monomial polynomial.

So the order will be IV, III, I, and II.

More about the polynomial link is given below.
