2.3283064
Step-by-step explanation:
Answer:

Step-by-step explanation:
The given line is defined by:
, where we see that the slope is 5 and the y-intercept 1.
In order to find a line perpendicular to the given one, we need it to have a slope that is the "opposite of the reciprocal" of the given slope.
"Opposite" means it would have its sign inverted (in our case from positive to negative); and "reciprocal means that instead of 5, it would be its reciprocal:
.
We can write this new line with such slope, and try to find its y-intercept (b) by using the given condition that requires it to go through the point (-5,-4) on he plane:

we require then that when
, the value of
.
Therefore: 
Then our final answer is that the new line should have the form: 
Answer:
V = 6 or V = -6
Step-by-step explanation:
Solve for V over the real numbers:
V^2 = 12^2 - 6 2 9
12^2 + 2 (-6) 9 = 36:
V^2 = 36
Take the square root of both sides:
Answer: V = 6 or V = -6
m = 4b+3 mikes age
m +b <138 mike +brother less than 138
4b+3+b<138
5b +3< 138
