The answer is 1000. 172,090 - 171,090 is 1000 so when you do it backwards and add 1000 to 171,090 you get 172,090. Hope this helps, good luck.

Solve the system of equations.<br> y= 3x +5<br> y= 8x +3
Lady bird [3.3K]

Answer:

y=6.2 and x=0.4 or (0.4,6.2)

Step-by-step explanation:

Since both expressions are equal to y, we can set them equal to each other and solve for x:

3x+5=8x+3

5=5x+3

2=5x

2/5=x

0.4=x

Now to solve y:

y=8(2/5)+3

y=16/5+3

y=3.2+3

y=6.2

Check answers:

6.2=3(0.4)+5

6.2=1.2+5

6.2=6.2

6.2=8(0.4)+3

6.2=3.2+3

6.2=6.2

Answers work, so y=6.2 and x=0.4 or (0.4,6.2) as an ordered pair

Find the slope(6,8) and (9,10)
USPshnik [31]

name the points

a=(x1,y1) b=(x2,y2)

a=(6,8) b=(9,10)

use the slope formula

m=\frac{y2-y1}{x2-x1}

replace

\begin{gathered} m=\frac{10-8}{9-6} \\ m=\frac{2}{3} \end{gathered}

answer= The slope is equal to 2/3

a=(9,10) b=(6,8)

using the formula

\begin{gathered} m=\frac{y2-y1}{x2-x1} \\ m=\frac{8-10}{6-9} \\ m=\frac{-2}{-3}=\frac{2}{3} \end{gathered}

slope will also be 2/3
