Answer:
After 167 miles the Budget rental deal would be better than the U-haul deal
Step-by-step explanation:
Let <em>x</em> be the number of miles.
Considering the U-haul plan the cost can be expressed as:
Consider the Budget rental plan the cost can be expressed as:
For the Budget rental plan to be better than the U-haul plan the relation between the two cost equation will be:
Substitute the equations of <em>u</em> and <em>b</em> and solve for <em>x</em>:
So after 167 miles the Budget rental deal would be better than the U-haul deal.
Answer:
9/36
Step-by-step explanation:
1/4=9/36
4×9=36, so 1×9=9
Answer:
Factor this polynomial:
F(x)=x^3-x^2-4x+4
Try to find the rational roots. If p/q is a root (p and q having no factors in common), then p must divide 4 and q must divide 1 (the coefficient of x^3).
The rational roots can thuis be +/1, +/2 and +/4. If you insert these values you find that the roots are at
x = 1, x = 2 and x = -2. This means that
x^3-x^2-4x+4 = A(x - 1)(x - 2)(x + 2)
A = 1, as you can see from equation the coefficient of x^3 on both sides.
Typo:
The rational roots can be
+/-1, +/-2 and +/-4
Step-by-step explanation:
Answer:
x = 16
Step-by-step explanation:
Alternate exerior angles are congruent when the lines are parallel
So, 8x - 14 = 5x + 34
3x = 48
x = 16
