Answer:
30% discount
Step-by-step explanation:
5*0.3=1.5
5-1.5=3.5
0.3 = 30%
Let x, x + 2 and x + 4 be three consecutive even integers;
Then x + x + 2 + x + 4 = - 396;
3x + 6 = -96;
3x = - 102;
x = ( -102 )÷3 ;
x = - 34;
The numbers are - 34 ; -32 ; - 30;
The largest of the three integers is - 30.
Answer:
(14.1, 14.1)
Step-by-step explanation:
If the point (x,y) is on the line y=x, then it has coordinates (x,x).
Find the distances from this point to points (-6,2) and (10,-9):
- distance from (x,x) to (-6,2):
- distance from point (x,x) to (10,-9):
Equate these distances:
Square this equation:
So, the coordinates are (14.1, 14.1)
Solve for x by cross multiplying x=3
<span>f(x) = 4x + 3
g(x) = -2x + 5
(f o g) (5) means the function of g when g is a function of 5
(the function of the function concept)
so we need to get g(5) firstly
</span>
<span>g(x) = -2x + 5
g(5)= -2(5) + 5 = -5
After that, f(g(5)) = f(-5) = 4(-5) + 3 = -20 + 3 = -17
I hope that helps
