Answer:
It tell the direction and the steepness of the line. Which means how much they rise or how much they fall, horizontal or vertical. It represent by the letter m
Step-by-step explanation:
m= y/x
more detail
m= y₂ - y₁ / x₂ - x₁
Answer:
The perfect -square trinomial
(9y+7)²
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given polynomial equation
81 y² + 126 y +49
⇒ 9² y² + 2(9)(7)y + 7²
⇒ (9y)² + 2(9)(7)y +7²
we will use formula
(a+b)² = a² + 2ab +b²
⇒ (9y+7)²
<u><em>Final answer:-</em></u>
The perfect -square trinomial
(9y+7)²
Here is the table of values:
Minutes Total cost
0 $3
1 $3.80
2 $4.60
3 $5.40
The equation representing the total cost is C = $3 + $0.80tt
<h3>What is the total cost?</h3>
The total cost of using a computer is a function of the initial charge, cost per minute and total number of minutes the computer was used.
Total cost = initial charge + (cost per minute x number of minutes)
C = $3 + ($0.80 x tt)
C = $3 + $0.80tt
Total cost when the computer is used for one minute: C = $3 +( $0.80 x 1) = $3.80
Total cost when the computer is used for two minutes: C = $3 +( $0.80 x 2) = $4.60
Total cost when the computer is used for three minutes: C = $3 +( $0.80 x 3) = $5.40
