Step 1.)
7x + 7 * 4.
We need to expand this term by multiplying a term and an expression.
The following product distributive property will be used:
A(B+C) = AB + AC
Numerical factors in this term have been multiplied.
In our example, the resulting expression will consist of 2 terms:
the first term is a product of 7 and x
the second term is a product of 7 and 4.
7x + (7 * 4)
Numerical factors in this term have been multiplied.
Which equals:
7x + 28
Hope you understand this and it helps. Have a great evening!
Answer:
y = -2x + 1
Step-by-step explanation:
The y-intercept is given by the point that is on the y-axis. (1)
This means that the answer contains a +1
Then you must find if the slope is positive or negative
In this case the slope is negative because the line goes "downhill" from left to right
Since the slope is negative it means that there will be a negative sign in the beginning of the equation
Next, to find the slope you need to find the rise over run
Since it is a negative slope the rise will be negative and the run will be positive.
To find the slope find two clear points on the graph such as (0,1) and (2,0)
To find the slope, use the slope formula
This would look like: (0-2)/(1-0)
Your slope will be -2x
Piece it all together and you get a final answer of y= -2x+1
Part B. f(x) = 90 + 0.11x
f(300) = 90 + 0.11(300) = 90 + 33 = $123
f(300) represents the total cost, in dollars, for renting a car for a week and driving it for 300 miles.
