Slope = 5
y = mx + b
2 =5(4) + b
b = 2 - 20
b = -18
<span>point-slope equation
y - 2 = 5(x -4)
</span><span>slope-intercept equation
y = 5x - 18
standard form
5x - y = 18</span>
18/12=21/Y | :3
6/12=7/Y
Y= 7*12/6
Y=7*12/6=14
18/12=X/10 | :2
X= 18*10/12
X=3*10/2
X=15
Subtract 4 from both sides
3x= 31-4
3x= 27
Divide both sides by 3 so x will be by itself. 27 divided by 3 is 9 so x=9
Answer:
145.2
Step-by-step explanation:
its pretty simple actually all you have to do is length times width times height
Rate of change= (y2-y1)/(x2-x1)=(306-360)/(16-10)= - 54/6= - 9
