Is this a multiple choice question? If so...what are the options?
Slope = (5+7)/(1-4) = 12/-3 = -4
slope = -4
y = mx + b
-7 = -4(4) + b
-7 = -16 + b
b = 9
equation
y = -4x + 9
Multiply 4 by 1/3.
4 × 1/3 ⇒
×
4/3 = 1.3333333...
1.33333 ⇒ 1 1/3
The robots will be doing 1 1/3 of the work.
The best and most correct answer provided from your question about the solution of a logarithmic equation is the fourth option which is x = 4. The solution to the equation is as follows:
We can transform the expression to:
(3x-7)^2 = 25
Solving for x using your algebra:
x = 4
I hope it has come to your help.
3/4(5)+3y=12
15/4+3y=12
3y=12-15/4
3y=33/4
y=33/4 /3
y=11/4
