[2(7)^2 - 5(7) + 4] Plugging the value of x, 7 into expression.
There are parentheses, so that means we have to work in them.
There are exponents, so we have to do those first.
[2(49) - 5(7) +4] Exponents.
There is multiplication, that we can do, so we do that left to right.
[98 - 35 + 4] Multiplication.
There is no division.
There is addition and subtraction, so we do those left to right.
[63 + 4] Subtraction.
67 Addition.
Final Answer: 67
Answer/Step-by-step explanation:
An equation that describes the relationship can be written as 
.
Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:
Substitute m = 70 into
The equation would be:
This equation can be interpreted as follows:
