Answer:
5x+10
Step-by-step explanation:
let f(x)=(x-10)/5=y
now write 'x' in term of y
i.e, x-10=5y
i.e, x=5y+10
now replace y with x to get required inverse of f(x)
=5x+10

Answer:
Step-by-step explanation:
To find which one is prime, let's try to factor them all. We can use the factoring by grouping method.
and
and
So this one is not prime, since you can still factor it.
and
and
So this one is not prime, since you can still factor it.
and
and
So this one is not prime, since you can still factor it.
and
and -x+2 cannot be further factored.
Therefore, is a prime.
Answer:
below
Step-by-step explanation:
You've been asked to use specific x-values. Simply replace the x in the equation for each of your x-values then graph.
first equation!!
(x,y)
y=-2x+5
x-value: -2
y=-2(-2)+5
y=4+5
y=9
(-2, 9)
x-value: -1
y=-2(-1)+5
y=2+5
y=7
(-1, 7)
x-value: 0
y=-2(0)+5
y=0+5
(0, 5)
x-value: 1
y=-2(1)+5
y=-2+5
y=3
(1, 3)
x-value: 2
y=-2(2)+5
y=-4+5
y=1
(2, 1)
second equation :)
(x,y)
y=x^2 +2
x-value: -2
y=-2^2 +2
y=4+2
y=6
(-2, 6)
x-value: -1
y=-1^2 +2
y=1+2
y=3
(-1, 3)
x-value: 0
y=0^2 +2
y=0+2
(0, 2)
x-value: 1
y=1^2 +2
y=1+2
y=3
(1, 3)
x-value: 2
y=2^2 +2
y=4+2
y=6
(2, 6)
third equation
(x,y)
y=√2 x+1
x-value: 1
y=√2 1+1
y=1+1
y=2
(1, 2)
x-value: 4
y=√2 4+1
y=2+1
y=3
(4, 3)
x-value: 9
y=√2 9+1
y=3+1
y=4
(9, 4)
x-value: 16
y=√2 16+1
y=4+1
y=5
(16, 5)
x-value: 25
y=√2 25+1
y=5+1
y=6
(25, 6)
fourth (last) equation :-)
(x,y)
y=4/x
x-value: -4
y=4/-4
y=-1
(-4, -1)
x-value: -2
y=4/-2
y=-2
(-2, -2)
x-value: -1
y=4/-1
y=-4
(-1, -4)
x-value: 0
y=4/0
y=0
(0, 0)
x-value: 1
y=4/1
y=4
(1, 4)
x-value: 2
y=4/2
y=2
(2, 2)
x-value: 4
y=4/4
y=1
(4, 1)
