Answer: 5
Step-by-step explanation: itswhere the 2 lines meet at the X
Answer:
-2x+3y =1.......(1)
y=3x-9........(2)
Now,
putting the value of y in equation (1),
-2x+3(3x-9)=1
or,-2x+9x-27=1
or,7x-27=1
or,7x=28
x= 4
Now putting the value of X in equation (2),
y=3×4-9
= 12-9
=3
(x,y)=(4,3)
22.90*1.05=24.045
sales tax is 5% added to 100% of the original cost making the actaul cost including tax $24.045
5 : - 1/6 = 0.167 out of 10 = 1.67 out of 100 = 16.7
even number 0.33 out of 10:- 3.3 out of 100:- 33
a prime number 0.5 out of 10: 5 and out of 100:- 50
multipl of 3:- 0/33 out of 10:- 3.3 and out of 100: 33
I will get you started.
Let sin x = u
Then 7sin^2x -14sinx+2=-5 become
7u^2 - 14u = - 5
7u^2 - 14u + 5 = 0
Steps:
1. Solve for u.
2. Back- substitute for u.
3. Take the arcsin on both sides to find the angle(s).
You finish.
