You're meant to make one side of the equation equal 0.
For example, the first problem is

+ 9k = -7
You'd add 7 to both sides, leaving you with

+ 9k +7 =0
And I assume you know how to factor??
Answer:
Step-by-step explanation:
Not sure if you need to show work.
Step-by-step explanation:
Volume =pir^h
V1=pi r1^h
V2=pir2^2h
Now,V1/V2=r1^2/r2^2
v1/v2=r1^2/(1.05)^2 ((r2=r1+5/100r1)
v1/v2=1/1.1025
v1/v2=0.907
(v1/v2-1)=0.0907×100%
(v1-v2)/v2=9.07%
increase in volume is 9.07%
Answer:
12x + y = 16
Step-by-step explanation:
Standard Form: Ax + By = C
Step 1: Write point-slope form
y + 4 = -12(x - 1)
Step 2: Find slope-intercept form
y + 4 = -12x + 12
y = -12x + 16
Step 3: Find standard form
12x + y = 16
