Answer:
4 sqrt(5)
8.94427191
Step-by-step explanation:
We want to find the length ( or distance) between the two points
d = sqrt( (x2-x1)^2 + (y2-y1)^2)
= sqrt( (8-0)^2 + (1 - -3)^2)
= sqrt( (8)^2 + (4^2)
= sqrt( 64+16)
sqrt( 80)
sqrt(16) sqrt(5)
4 sqrt(5)
8.94427191
Step-by-step explanation:
A. 5x=12x-14
you will simplify the equation to the form, which is simple to understand
5x=12x-14
We move all terms containing x to the left and all other terms to the right.
+5x-12x=-14
We simplify left and right side of the equation.
-7x=-14
We divide both sides of the equation by -7 to get x.
x=2
B. 5B+12=BB=28
you will move all terms to the left:
.5B+12-(BB)=0
you will move all terms containing B to the left, all other terms to the right
.5B-BB=-12
Answer:
x = 1
Step-by-step explanation:
5 - 5 + 3x = 8 - 5
3x = 3
3x/3 = 3/3
x = 1
Answer: C(x) = (8 php)*x + 50 php.
Step-by-step explanation:
In a linear equation:
y = a*x + b
a is the slope.
x is the variable
b is the y-intercept.
In this case, we have
The rent is 50 php fixed, plus 8 php per hour.
Then we will pay the 50php only one time, and it does not depend on the number of hours that we rent, then this is the y-intercept.
then if we rent the bike for x hours, we will pay a plus of x*8 php.
Then the total cost for x hours, C(x), will be
C(x) = (8 php)*x + 50 php.
Then the slope is 8 php, and the y-intercept is 50 php.
