Which expression gives the distance between the points (5, 1) and (9, -6)?
Vesna [10]
So the distance formula: d = rad (x2 - x1)^2 + (y2 - y1)^2
it doesn't matter what order you do, you just have to make sure it's a y coordinate for y and an x coordinate for x.
rad (9-5)^2 + ((-6)-1)^2
rad 4^2 + (-7)^2
rad 16 + 49
rad 65

Graph the line with slope <br> 2<br> 5<br><br> and <br> y<br><br> -intercept <br> −<br> 7<br><br> .
tia_tia [17]

Answer:

See attachment

Step-by-step explanation:

We want to graph the line with slope

m =  \frac{2}{5}

and y-intercept ,

b =  - 7

The equation of this line is

y =  \frac{2}{5}x - 7

Starting at -7 on the y-axis, we run 5 units and rise 2 units right.

Then draw a line through the y intercept and the new point

The graph is shown in the attachment.

2(5x+7)=16 <br> what the answer?
Marianna [84]

Answer:

x = 1/5

Step-by-step explanation:

2(5x + 7) = 16

2 * 5x + 2 * 7 = 16

10x + 14 = 16

10x = 16 - 14

10x = 2

x = 2/10

x = 1/5
