Step-by-step explanation:
For this composition function,
, we should substitute
anytime we see an
variable in
:
![x^{2} + 1](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B%201)
![[g(x)]^{2} + 1](https://tex.z-dn.net/?f=%5Bg%28x%29%5D%5E%7B2%7D%20%2B%201)
![(3x)^{2} + 1](https://tex.z-dn.net/?f=%283x%29%5E%7B2%7D%20%2B%201)
![9x^{2} + 1](https://tex.z-dn.net/?f=9x%5E%7B2%7D%20%2B%201)
Okay, 5 can be equal 5/1, 10/2, 15/3, 20/4, etc. In other words, it means that some number over or divided the different number like some examples that shown above must equal 5. Hope it help!
Answer:
0.72
Step-by-step explanation:
1000ml in a litre. 12 x 60 ( minutes in an hour) = 720.
720/1000=0.72
Step-by-step explanation:
(a/b) + (c/d)
Find the common denominator. In this case, bd. So multiply the first fraction by d/d, and the second fraction by b/b.
(ad)/(bd) + (bc)/(bd)
Add the fractions.
(ad + bc) / (bd)
First let us find the slope:
Points (x , y) = (-2 , 1) and (5 , 8)
Slope m = (y₂ - y₁)/(x₂ - x₁) = (8 - 1) / (5 - -2) = 7/(5 + 2) = 7/7 = 1
Slope m = 1.
Equation of a line by point slope form y - y₁ = m(x - x₁)
Using the point (5, 8) x₁ = 5, y₁ = 8, m = 1
y - y₁ = m(x - x₁)
y - 8 = 1(x - 5)
y - 8 = 1*(x - 5) Point slope form of equation
But let's just simplify further
y = x - 5 +8
y = x + 3
<span>Equation is also y = x + 3
