Answer:
20%.
Step-by-step explanation:
That is (60 - 50) / 50

= 20%.
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
x < -1
The solution is the interval ----> (-∞,-1)
All real numbers less than -1
On a number line the solution is the shaded area at the left of x=-1 (open circle)
using a graphing tool
see the attached figure
Hope there are
3(x-4) >= 5x^2 or this 2 from the end what mean ?
3x-12 >=5x^2
0>=5xˇ2 -3x +12
5x^2 -3x +12 =0
D = 9 -240 = -150 so what mean that this equation has not real solutions
Answer:
4
Step-by-step explanation:
25/100 x 80/1 = 20/1
80 - 20 = 60
30/100 x 80/1 = 24/1
80 - 24 = 56
60-56=4
