Whatis the slope of the line whose equation is 2x - 4y=10?

Mathematics

Degger [83]3 years ago

The slope of the line is 1/2.
Add '4y' to both sides of the equation, then subtract '10' both sides.
then you get 4y = 2x - 10
divide the equation by 4
you get: y = 1/2 x - 2.5
the equation for a straight line is y = mx + c where m is the slope

The ratio of Isabella's money to Shane's money is 3:11. If Isabella has $33, how much money do Shane and Isabella have together?
Sergio039 [100]
The ratio of Isabella’s money to Shane’s money is 3:11

Isabella has $33.   

We can make a proportion to solve for how much money Shane has.   
A proportion is two ratios that are set equal to each other.  

Let’s call Shane’s money ‘S’   

We get this proportion:   3/11 = 33/x   

If we cross multiply we get:   
(33) * (11) = (3) * (x)   

Simplifying it, we get:
363 = (3) * (x)   

Divide both sides by 3, we get:
x = 121   

However, the question asks how much money they have together. 

Isabella + Shane = Total
33 + 121 = $154   

<span>They have $154 together.</span>

How to divide fractions
Anna [14]

First leave the first fraction alone.

Then turn the division sign into a multiplication sign.

Flip the second fraction over ( find its reciprocal ).

Multiply the numerators of the two fractions together. This result will be the numerator ( the top part ) of your answer.

Multiply the denominators of the two fractions together. The result will be the denominator ( the bottom part ) of your answer.

Then simplify your fraction by reducing it to the simplest terms.

Which of the following best describes the graph of the polynomial function below?
WARRIOR [948]

Answer:

A. The graph has two zeroes.

Step-by-step explanation:

A <em>zero of a polynomial</em> is a value of x that makes the polynomial equal to zero.

In other words, it is <em>an x-intercept</em>.

The graph crosses the x-axis twice, so there are two zeroes.

The equation of the line with slope = 3, going through point (2, 4) is:
Marina86 [1]

(\stackrel{x_1}{2}~,~\stackrel{y_1}{4})\hspace{10em} \stackrel{slope}{m} ~=~ -3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{4}=\stackrel{m}{-3}(x-\stackrel{x_1}{2}) \\\\\\ y-4=-3x+6\implies y=-3x+10
