<span>Z + 1/z = 2
Multiply 1 by both sides
z+z=2
Add z and z together
2z=2
Divide both sides by 2
Final Answer: z= 1</span>
Answer: Okay so do 3x7.5 then 3x11.5 then 7.5x11.5 then add it up and you should get 143.25
7. Subtract 5.7 from both sides to get the variable on one side. (f=2)
8. Subtract 5.52 from both sides to get the variable on one side. (f=5)
9. Add 3.77 to both sides so the variable will be on one side.
10. Add 10.58 to both sides.
11. Divide by 2.2 on both sides. 2.2b/2.2 will leave you with the variable b. 8.8/2.2=4; b=4.
12. Divide by 2.5b on both sides. 2.5b/2.5 leaves b. 10/2.5= 4; b=4.
Answer:
Ray, you need the slope-intercept formula y=mx+b
Step-by-step explanation:
Next you'll need 2 points, any points are fine. Just find two easy ones along the line. I'll just pick Point 1 as P1 = ( 0,4) and point 2 as P2 = (4,0) because they are easy to work with.
next use
point P1 (0,4) in the form (x1,y1)
point P2(4,0) in the form (x2,y2)
slope = m
m = (y2-y1) / (x2-x1)
m = (0-4) / (4-0)
m = -4 / 4
m = -1
now use the point slope with one of the points, to find the slope-intercept form.
y - y1 = m(x -x1)
y - 4 = -1(x-0)
y -4 = -x
y = -x + 4
note:
y = mx +b
y = (-1)x + b is the form. see?
