Slope = $\frac{Y2 - Y1}{X2 - X1}$

$\frac{8 - (-5)}{6 - (-4)}$

Your final answer is: $\frac{13}{10}$

How to solve - 10+5x=7x-4

Triss [41]

10+5x=7x-4
1. simplify 7x - 5x
10=2x-4

2. add four to both sides
10+4=2x
+ 4 4
14=2x

3. divide 14 to both sides
14=2x

Answer:

y=2x+7

Step-by-step explanation:

The slope of the new line is 2 because that is the opposite of -1/2

To find the equation of the line, plug the points (-2,3) into point-slope form:

y-y1=m(x-x1).

y-3=2(x+2)

Multiply (x+2) by 2 and simplify to get the final answer.

y-3=2x+4

y=2x+7

Fill in the blanks:

ser-zykov [4K]

Answer:

$8943=8\times 1000+9\times 100+4\times 10+3\times 1=8\times 10^3+9\times 10^2+4\times 10^1+3\times 1$

So in blanks there will be 8, 9, 4, 3

Step-by-step explanation:

We have given that $8943=.....\times 1000+....\times 100+....10+....1=....10^3+....10^2+....10^1+....1$

We have to fill the blanks

We know that $8\times 1000=8000$

$9\times 100$

$4\times 10$

$3\times 1$

When we add all then

$8000+900+40+3=8943$

So in the blanks there will be 8 , 9, 4 , 3

We also know that $8000=8\times 10^3$

$900=9\times 10^2$

$40=4\times 10^1$

$3\times 1=3$

So $8943=8\times 1000+9\times 100+4\times 10+3\times 1=8\times 10^3+9\times 10^2+4\times 10^1+3\times 1$
