Some friends plotted the locations of their house on a map. brianna's house is at (1,6), Jordan's house is at (5,3). What is one

Rufina [12.5K]

Let
A (1,6)------> location <span>brianna's house on a map
B </span>(5,3)------> location Jordan's house on a map

we know that
One possible path from brianna's house to jordan's house it's a straight line ( <span>the shortest distance)</span>

using a graph tool
see the attached figure

find the distance points AB
d=√[(y2-y1)²+(x2-x1)²]-----> d=√[(3-6)²+(5-1)²]----> d=√[3²+4²]
d=√25----> d=25 units

the distance from brianna's house to jordan's house is 25 units

riley makes a mistake in step 2 while doing her homework. What was her mistake? StartFraction x Over x squared minus 5 x + 6 End

exis [7]

The mathematical mistake that Riley made is that: "She used the wrong common denominator." (Option A)

<h3>What is a Common Denominator?</h3>

A common denominator is a factor that is similar to all the fractions in the sequence of equations.

Hence the correct answer is:

(2(2x² - 6x + 9))/((x-3) (x-2) (x+3))

See the correct sequence of steps below:

Step One - the Expression is given as:

(x/(x-3)(x-2)) + (3/(x+3))

Step 2 - Find the common denominator and rewrite the expression so that the numerators are above the common denominators.

Hence we have: (x (x+3) + 3(x-3) (x-2))/(x-3)(x-2)(x+3)

Step 3 Apply the Law of Multiplicative Distribution:

Hence we have (x² +3x+3x²-9x-6x+16)/(x-3)(x-2)(x+3)

Step 4 - Collect Like Items

This gives us: (x²+3x²)+(3x-9x-6x)+18/(x-3)(x-2)(x+3)

Step 5 Sort for like coefficients

This gives us: ((1+3)x² +(3-9-6) * x + 18)/(x-3)(x-2)(x+3)

Step 6 - check for the sum or difference

This gives us: (4x²+(3-9-6) * x+ 18)/(x-3)(x-2)(x+3)

We simplify and factor the expression to get

(2(2x²-6x+6)/(x-3)(x-2)(x+3).

A mother wants to invest $5,000.00 for her son's future education. She invests a portion of the money in a bank certificate of d

Lostsunrise [7]

Let us say, the CD amount she invested is "c"
and the amount she invested in the savings bond is "s"

she invested a total of 5,000
so, whatever "c" is and "s" is, c + s = 5,000

now, the CD account earned 4% in interest
4% in decimal form is 4/100 or 0.04

she also earns 7% from the saving bonds,
7/100 is 0.07

the interest earned after one year are 300
that is, the 4% per year and the 7% per year add up to 300 bucks
so, one can say that

0.04c + 0.07s = 300

$\begin{cases}
c+s=5,000\to s=\boxed{5,000-c}
\\ \quad \\
0.04c+0.07s=300\to 0.04c+0.07(\boxed{5,000-c})=300
\end{cases}
\\ \quad \\
\textit{solve for "c", or CD amount}$
