As function is = 4x
so
4x=-x+5
5x=5
x=1
Answer:
The height of the triangle is 3.2 cm.
Step-by-step explanation:
The area of the triangle = 
Base of the triangle = 10 cm
Height of the triangle = h cm
Area of the triangle = 
h = 3.2 cm
The height of the triangle is 3.2 cm.
A function is defined as a set of points for every x-value, there is only one y-value.
So, you can't have two y-values for every x-value.
Thus, (B) would be a relation, because x = 7 has two y-values, and as such, doesn't satisfy the condition of a function.
Answer:
$76.80
Step-by-step explanation:
120/80 equals how many times the next route is larger than the first one. Which is 1.5 times larger.
Take the first earning of 51.20 and multiply by 1.5 to get 76.80
120/80=1.5
51.20*1.5=76.8
On the next route the truck driver earns $76.80.
