Answer:
800 miles
Step-by-step explanation:
Let the number of miles be represented by x
Company A for $110 a day plus $0.80 per mile.
$110 + $0.80 × x
110 + 0.80x
Company B charges $30 a day plus $0.90 per mile to rent the same truck.
$30 + $0.90 × x
30 + 0.90x
110 + 0.80x = 30 + 0.90x
110 - 30 = 0.90x - 0.80x
80 = 0.1x
x = 80/0.1
x = 800 miles
800 miles driven per day makes the rental cost for Company A a better deal than Company B's
12(2)+12(3)= (3+2) (12)= 5(12)=60
The answer would be:
3q x (2q + 1) x (q^2 - 4)
Hope this helped :)
An equation expresses the relation between variables. A relation between y and x can be drawn as a graph in the xy plane.
In order to do that, you want to "plug in" a value for x, and then get the result as a value for y. With an equation that expresses y in terms of x, you can do just that. For example, plug in the value x=3 in the equation y=2x+4 easily gives you y=10. You plot the point (3,10) and repeat for different x.
If y is not clearly expressed in terms of x, you get equations like: 2x + 4y + x/y = 0. You cannot plug in an x and calculate a y in an easy way.
Most of the time you'll be able to rewrite the equation in the right "pluggable" form. In fact, when you have an equation in this form, it maps one to one to a function f(x). y=2x+4 and f(x)=2x+4 is kind of the same thing. "f is a function of x" and "y is expressed in terms of x" are similar statements.
Answer:
(18,2)
Step-by-step explanation:
Let's start by determining the transformation of Rectangle J′K′L′M′
We can look at L.
In the original rectangle, L is at (-4,-2)
In the transformation, L' is at (9,-5)
|-4-9|=|-13|=13
|-2-(-5)|=|-2+5|=3
So the transformation is 13 units right and 3 units down.
In trapezoid STUV, the coordinates of T are are (5,5)
We need to move it 13 units left and 3 units down.
This means we add 13 to the x coordinate and subtract 3 from the y coordinate.
5+13=18
5-3=2
The location of T' will be (18,2)
