8x + y = 12 (substitute 3 for y)
8x + 3 = 12 
8x = 9 
x = 9/8 

If y = 3 and 8x + y = 12, then x = 9/8.

HOPE THIS HELPS!!

8x + 3 - 3 = 12 - 3 8x = 9 8x/8 = 9/8 x = 1.125

Find the slope Thxxxx

Helga [31]

Answer:

-The slope:

$m = \frac{3}{2}$

Step-by-step explanation:

-To find the slope, you need this trick:

$m= \frac{rise}{run}$

-So, according to the graph, start to the first doted point which is (0,1) to get to the second doted point, which is (2,4) on the graph, by counting how far up and how far across:

Rise: 3

Run: 2

$m= \frac{3}{2}$

So, therefore the slope is $\frac{3}{2}$ .

Answer:

The answer is 140

Step-by-step explanation:

When the total measurements of the six-shaped corners is equal 720

Then x equal to

$x = 720 - (120 + 120 + 120 + 130 + 90) = 140$

If you need any explanation in it or anything on math you can communicate with me on Whats on this number +201557831028 or in email or face or anything

A car starts from an initial velocity of 10m/s and accelerates at 2.5m/s².how long will it take the car to reach a speed of 40m/

PIT_PIT [208]

A=(v-u)/t
We know a=2.5, v=40, u=10, so:
2.5=(40-10)/t
2.5t=40-10
2.5t=30
Divide both sides by 2.5
t=12 It takes 12 seconds for the car to reach 40m/s

To find out how far it went, you do:
d=v+1/2 at^2
d=10+1/2(2.5)(12)^2
d=10+1/2(2.5)(144)
d=10+(1.25)(72)
d=10+90
d=100m

Hope this helps :)
