Answer:
Step-by-step explanation:
Put the values of x and y in the equations and solve the resulting system.
A(2) +(-3) = 5
A(2) +B(-3) = 20
__
The first equation tells the value of A:
2A = 8 . . . . add 3
A = 4 . . . . . .divide by 2
This and the second equation tells the value of B:
(4)(2) -3B = 20
-3B = 12 . . . . . subtract 8
B = -4 . . . . . . . divide by -3
The values of A and B are 4 and -4, respectively.
Answer:
P and 3
Step-by-step explanation:
Answer:
The answer is (b) cscx
Step-by-step explanation:
∵ secx = 1/cosx
∵ tanx = sinx/cosx
∴ secx/tanx = 1/cosx ÷ sinx/cosx
= 1/cosx × cosx/sinx
= cscx
Answer:
-2.7, -10, -14.6
Step-by-step explanation:
Answer:
1/4 is the clope of the line
Step-by-step explanation:
a slope is just a rise ofver run from one dot to anothor so you go up 1 and over 4 and if you dont do the 2 dots that are closest to each other you have to simplify you r exspresion you will always get 1/4 on this graph
