Answer:
<h2>25</h2>
Step-by-step explanation:
The rate of change of number of tree y on x branches of a tree is expressed as shown;
m = Δy/Δx where;
m is the rate of change
Δy is the change in number of leaves between 3 and 4
Δx is change in number of branches between 3 and 4
m = Δy/Δx = y₂-y₁/x₂-x₁
From table between 3 and 4, y₂ = 100, y₁ = 75, x₂ = 4, x₁ = 3
m = 100-75/4-3
m = 25/1
m = 25
<em>Hence the rate of change between 3 and 4 branches is 25</em>
Answer:
8
Step-by-step explanation:
m2 - 2mn + n2 ,m = -2 and n = 4
= -2( 2 ) - 2( -2 )( 4 ) + ( -2 )2
= -4 + 4( 4 ) - 4
= -4 + 16 - 4
= 8

=(2x−3)(3x+1).
Then, f(x)=0⟹2x−3=0 and 3x+1=0.
Therefore, 2x=3 and 3x−−1.

Answer:
2 liters
Step-by-step explanation:
The applicable proportion can be written ...
amount/percentage = 1260 mL/63% = x/100%
2000 mL = x = 2 liters
The full carton held 2 liters of milk.
