U(w(x))=-5(5x-3)+5
u(w(x))=-25x+15+5
u(w(x))=-25x+20 so
u(w(5))=-25(5)+20
u(w(5))=-125+20
u(w(5))=-105
Answer:
Definitely A)
Step-by-step explanation:
Answer:
5x + 10y = 90
Step-by-step explanation:
If she hiked a total of 90 miles, we can say that 90 miles equals 10 multiplied by the number of times she hiked the 10 mile trail, plus 5 multiplied by the number of times she hiked the 5 mile trail.
x is the number of times she hiked the 5 mile trail, y is the number of times she hiked the 10 mile trail.
Writing this statement in an algebraic form would give us:
5x + 10y = 90.
There's no cube shown but we can guess the diagonal is the long diagonal.
In a rectangular parallelpiped (aka a box) with dimensions a × b × c the long diagonal x satifies a 3D version of the Pythagorean Theorem,
x² = a² + b² + c²
In a cube a=b=c
x² = 3a²
x = a√3
