X = 7
5 + x can also be written as 5 + 7
5 + 7 = 12
multiply 40 by 30% to find the discount then subtract
40 * 0.30 = 12
40-12 = 28
they would cost $28
Answer:
Step-by-step explanation:
hello :
f(x)=4^x so : f(-2)=4^(-2) = 1/4^2 = 1/16
In the figure we have three parallel lines cut by two transversals
The theorem stares:
If two or more parallel lines are cut by two transversals, then they divide the transversals proportionally.
Applying this theorem we have:

To solve for x we cross multiply
6x=20
Dividing both sides by 6 we have:

The second option x=
is the right answer
Answer:
Step-by-step explanation:
There are 3 possibilities for the graph as shown in the figure.
(a) having zero intersection
(b) having one intersection point (touching point)
(c) having two intersection points.
So, the greatest possible number of intersections for these graphs is 2 as shown in figure (c).
