Answer:
y = 2x - 7
Step-by-step explanation:
Looks like we already have the slope of this line: It is 2. Working with the point (1, -5), we have x = 1 and y = -5 and can from this info easily find the y-intercept, b:
y = mx + b becomes
y = 2x + b, which in turn becomes
-5 = 2(1) + b, or
b = -7,
and so the desired equation is y = 2x - 7
We cannot solve for a numerical value of p, but rather set the equation equal to p.
w = 4/(p+2)
(Multiply both sides by the denominator)
w(p+2) = 4
(divide both sides by w)
p+2 = 4/w
(Subtract 2 from both sides) (also 2/1)
p = (4-2)/w
p = 2/w
To get x by itself, you would add 13 to both sides. x=115
I'm going to assume you mean 3 to the power negative 5.
3^-5
Use rule [ x^-y = 1/x^y ]
3^-5 = 1/3^5 = 1/243
Best of Luck!
