Find the rate of change of y=2x+4
1 answer:
Answer:
<h3>2</h3>Step-by-step explanation:
Since this is a linear function, the rate of change is the same as the slope of the function.
Rate of change is a ratio that compares the difference of two outputs and the difference of two inputs of a function. It is the , the Δy/Δx (the symbol "Δ" is delta, and means change or difference).
In the case of this function, the slope and rate of change are the same because it is linear, but they are not the same in quadratic or exponential functions because the rate of change is not constant.
The general equation for a linear function is y=mx+b, where "m" is the slope and "b" is the y-intercept, or initial value. In the equation y=2x+4, the "m" value is 2, so the rate of change is 2.

Answer:
U₂₁ and U₂₂ fits in the line of upper triangular
Step-by-step explanation:
As explain in the question
An upper triangular matric is square matrix with all zeros below its daignal. A lower triangular matrix is a square matrix with all zeros above its diagonal.
(as shown in the attached image)
(a)for all 3×3 upper triangular matirices U, verify that U2 is also upper triangular
for a matrices U (having a 3*3 matrix), assuming for example, U is given below:
U =
the element in the upper triangular are 1,2,3,5,6,9 (U₁₁, U₁₂, U₁₃; , U₂₂, U₂₃, U₂₂)
while lower triangular are 0,0,0, the element in the lower triangular are (U₂₁, U₃₁,U₃₂)
U₂₁ and U₂₂ fits in the line of upper triangular
