<h3>Answer:  the fraction -2/25</h3>

Explanation:

Use the slope formula. We subtract the y values together, and do the same for the x values as well. Subtract in the same order each time. Then you divide the two results. Reduce the fraction if possible.

m = (y2 - y1)/(x2 - x1)

m = (14 - 18)/(30 - (-20))

m = (14 - 18)/(30 + 20)

m = -4/50

m = -2/25

Answer:

-\frac{2}{25}

Step-by-step explanation:

Slope is rise over run.

m=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}

We are given the points (–20, 18) and (30, 14).

m=\frac{14-18}{30+20}=\frac{-4}{50}=-\frac{4}{50}=-\frac{4/2}{5/2}=\boxed{-\frac{2}{25}}

The slope is -2/25.

Answer:

Answer: B, 6/11

Step-by-step explanation:

<em>Well we know that 3+2+1=6+3=9.</em>

<em>So that means we will add the 2 brown crayons to the denominator.</em>

<em>The denominator before we added 2 to it, it was 9 as a common denominator. If we want to get the common numerator we are going to have to add the top and that will become 9 then you will have to subtract that by 3</em>

<em>6/11 is also the smallest number that you can get.</em>

<em>You can turn the fraction into a decimal and have it that way to make it easier.</em>

<em>When you turn a fraction into a decimal the number is always the same but with comparing numbers it is a lot easier to do than comparing fractions</em>

Hope this helps, and if it did I would appreciate it if you marked me as Brainllest. Have a wonderful day!

<h3>What is algebra?</h3>

Algebra is the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

Algebra is divided into different sub-branches such as elementary algebra, advanced algebra, abstract algebra, linear algebra, and commutative algebra.

Elementary algebra: elementary algebra, branch of mathematics that deals with the general properties of numbers and the relations between them. Algebra is fundamental not only to all further mathematics and statistics but to the natural sciences, computer science, economics, and business.

From the given question,

\sqrt[4]{15^7} This expression can also be written in the form of a^\frac{b}{c}

We will convert \sqrt[4]{15^7} to the required form:

(15^\frac{7c}{4b} )\left \{ {{a=15^\frac{7c}{4b} } \atop {b=b} , c = c} \right.

Hence,

From the above equation we get the value of b and c is 4 and 7.

A line passes through the point (-4,6) and has a slope of 5/4
kondaur [170]

Answer:

4y-5x-44=0

Step-by-step explanation:

It passes through one point with the formula being

y-y1=m(x-x1)

y-6=5/4(x-(-4))

y-6=5/4(x+4)

cross multiply

4(y-6)=5(x+4)

4y-24=5x+20

collect like terms

4y-5x=20+24

4y-5x=44

4y-5x-44=0
