Answer:
Step-by-step explanation:
The negative sign in y = -2x + 2 tells us immediately that the y intercept of the graph of this function is (0, 2). If we start at (0, 2) and increase x by multiples of 1, y decreases by 2 in each case (the slope of this line is -2). Thus, we begin a table as follows:
x y = -2x + 2
0 2
1 -2(1) + 2 = 0
2 -2(2) + 2 = -4 + 2 = -2
and so on:
x y = -2x + 2
0 2
1 0
2 -2
3 -4
4 -6
Answer:
The dependent variable is the number of plays he carries the ball.
The independent variable is the number of touchdowns he scores.
The dependent variable is the number of yards he gains.
Step-by-step explanation:
Tom's coach keeps track of the number of plays that Tom carries the ball and how many yards he gains. Select all the statements about independent and dependent variables that are true.
The dependent variable is the number of plays he carries the ball.
The independent variable is the number of plays he carries the ball.
The independent variable is the number of touchdowns he scores.
The dependent variable is the number of yards he gains.
The dependent variable is the number of touchdowns he scores.
y = kx
y = dependent variable. it is the variable that is explained by the dependent variable
x = is the variable that explains the dependent variable
Ok I think u have to do subtraction and in a negative way
Answer:
-1
Step-by-step explanation:
Given,
f(x) = -x² + 4x - 1 and x = 0
Putting the value of x we get,
f(0)= 
+ (4 X 0) - 1
= -0+0-1
=-1
∴f(x)= -1
So, the required value is -1
