First you have to plug in your information into the formula- y=mx+b
So we know the y is 2, the slope (m) is 1/2, the x is 2 and we don't know the b. Do plug it in the formula and solve... you should get 2=1/2(2)+b you will end up with 1=b and the final answer is y=1/2x+1
The triangles are similar by Angle-Angle
18 mile per hour
Step-by-step explanation:
average speed = total distance covered by total time taken
so, avg. speed = ( 2+ 7 ) / ( 20 + 10 )
= 9 / 30
= 3 / 10
= 0.3 miles per minute
= 18 mile per hour
<span>35.5/13 = 3.50
there ye go</span>
2 + y= -3
subtract 2 from both sides
y= -5
Check:
2 + -5= -3
-3= -3
Hope this helps! :)
