Answer:
Step-by-step explanation:
Solving by elimination and substitution:
x
+
y
=
7
x
−
y
=
−
3
on adding the two equations
y gets cancelled
x
+
y
=
7
x
−
y
=
−
3
2
x
=
4
x
=
4
2
=
2
substituting this value of x
in equation 1:
x
+y
=
7

+
y
=
7
y
=

y
=
5
the solution for the system of equations are :
x
=
2
y
=

Hope it helps pls mark as brainliest
Yes, for every value of x, there is only one value of y. This means that y is a function of x.
Answer:
15-44+32= 3
Step-by-step explanation:
Answer:
jacket 80
shoes 32 and 16
shirt 9 , 8.04, 4.08
Step-by-step explanation:
you need to multiply the original cost by the percentage off and then subtract from the original
example
Jacket is originally priced at $120 it is on sale for 1/3 off which means that if you divide 120 by 3 you will get 40. but you would have to subtract the 40 from 120 giving you 80
Answer:
Step-by-step explanation:
Correct option is
D
[1,(1+π)
2
]
f(x)=(1+sec
−1
(x))(1+cos
−1
(x))
Here the limiting component is cos
−1
(x), since the domain of cos
−1
(x) is [−1,1].
Therefore,
f(1)=(1+0)(1+0)
=1
f(−1)=(1+π)(1+π)
=(1+π)
2
Hence range of f(x)=[1,(1+π)

]
