I believe the answer would be x20. Between the two parentheses there's a multiplication symbol. So you would just pretend that the parentheses aren't there cause the variable(s) (x) is/are like terms. So you would just multiply 10 times 2 and put out the x back in front of it
Let's start with the x coordinates.
-8 is on the left, and -4 to the right, so that will help organize this.
the line goes from -8,-9 to -4,-8. it moved 4 over the x axis and rose 1 over the y axis.
rise/run so 1/4 is the slope.
y=(1/4)x - 7
Answer =37.5 rows of two
Explanation= you can do 75 divid by 2 to get rows of two each of 75.
Divide -20 by 5 to get -4.
Multiply -4 and -3 to get 12.
Multiply 4 and -2 to get -8.
Multiply -8 and -1 to get 8.
Add 12 and 8 to get 20.
Calculate 4 to the power of 2 and get 16.
Subtract 16 from 20 to get 4.
Answer:
The function graphed is f(x) = 3x + 1
See that the y=intercept is at (0,1). That's where the +1 comes from.
Note that the graph goes up 3 spaces every time it goes 1 to the right. 3/1 = 3 is the slope.
The answer to 12 is C.
The answer to 13 is B. Neither is a function. For a function of x to exist, for every x, there must be only one y. In both tables, there's a number for x that gives two different y's.
