Answer:
25
Step-by-step explanation:
Is means equals and of means multiply
16 = 64% * W
Change to decimal form
16 = .64 * W
Divide each side by .64
16/.64 = .64W/.64
25 = W
Answer: Hope This Helped!!!! (:
Step-by-step explanation:
<span>Simplifying
x4 + -2x3 + 6x2 + -2x = 5
Reorder the terms:
-2x + 6x2 + -2x3 + x4 = 5
Solving
-2x + 6x2 + -2x3 + x4 = 5
Solving for variable 'x'.
Reorder the terms:
-5 + -2x + 6x2 + -2x3 + x4 = 5 + -5
Combine like terms:
5 + -5 = 0
-5 + -2x + 6x2 + -2x3 + x4 = </span>0
<span>The solution to this equation could not be determined</span>
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:

Answer: y = 3x+18</h3>
Slope = 3
Y intercept = 18
==================================================
Work Shown:
m = slope
m = (y2-y1)/(x2-x1)
m = (0-(-9))/(-6-(-9))
m = (0+9)/(-6+9)
m = 9/3
m = 3 ... is the slope
-------
y = mx+b
y = 3x+b .... plug in the slope
-9 = 3(-9)+b ... plug in the point (x,y) = (-9,-9)
-9 = -27+b
-9+27 = -27+b+27 .... adding 27 to both sides
18 = b
b = 18 ... is the y intercept
---------
We found that m = 3 is the slope and b = 18 is the y intercept
y = mx+b turns into y = 3x+18
