<span> the answers are B and D
hope this helps out :}</span>
Answer:
b
Step-by-step explanation:
got it right
<span> 5*(4*x-5)-(155)=0
</span><span> 5 • (4x - 5) - 155 = 0
</span> Pull out like factors :
20x - 180 = 20 • (x - 9)<span>
</span> 20 • (x - 9) = 0
Solve : <span> 20 = 0
</span>Solve : x-9 = 0<span>
</span> <span>Add </span> 9 to both sides of the equation :<span>
</span> x = 9<span>
</span>hope that helps!!
To find slope between two given points:
(y2-y1)/(x2-x1)
Find the difference between the first two points
12-9.5/2-1 = 2.5/1 = 2.5
14.5-12/3-2 = 2.5/1 = 2.5
17-14.5/4-3 = 2.5/1 = 2.5
The rate of change between each point is 2.5
