1 answer:
Answer:
The initial value of the function is 25 and the rate of change is - 5.
Step-by-step explanation:
The table gives the ordered pairs of linear relation and they are (1,20) and (3,10).
Now, the equation of the linear relation that includes those ordered pairs will be
⇒ y - 10 = - 5(x - 3)
⇒ y - 10 = - 5x + 15
⇒ y = - 5x + 25
Therefore, the initial value of the function is 25 and the rate of change is - 5. (Answer)

Answer:
Given : JKLM is a rectangle.
Prove: JL ≅ MK
Since, by the definition of rectangle all angles of rectangles are right angle.
Thus, In rectangle JKLM,
∠ JML and ∠KLM are right angles.
⇒ ∠ JML ≅ ∠KLM
Since, JM ≅ KL (Opposite sides of rectangles are congruent)
ML ≅ ML ( Reflexive )
Thus, By SAS congruence postulate,
Δ JML ≅ Δ KLM
⇒ JL ≅ MK ( because corresponding parts of congruent triangles are congruent)
Hence proved.
Answer:
<h2>(55/27, 32/9)</h2>Step-by-step explanation:
The system of equations is
The first step is to arrange like terms in colums, which is already done.
Then, we need to multiply a number by one equation in such way where we get opposite like terms. Notice that we need to multiply the first equation by -1
Then, we sum equations to obtain the value of one variable.
Now, we use this value to find the second variable
Therefore, the solution is (55/27, 32/9).
