Answer:
The value of a is 9 and b is -8
Step-by-step explanation:
We need to find two numbers that add up or subtract off to 1.
Then we also use the same two numbers that multiply and get -72.
Let's see:-
- 9 and -8 seem like correct values.
Because 9+(-8) is 9-8 = 1
And 9(-8) is -72.
Therefore:
The value of a is 9 and the value of b is -8 according to form of (x+a)(x+b)
If the function is y = 4.5x. Then the rate of change of the function expressed as a unit rate will be 4.5.
<h3>What is the linear system?</h3>A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
A bike rental company charges a fee per hour.
The charge, in dollars, is the same each hour.
The ordered pairs (3, 13.50) and (5, 22.50) represent the corresponding hours, x, and cost, y.
Then the linear equation is given as
Then the rate of change of the function expressed as a unit rate will be
