Answer:
I think number one is 3w I could be wrong so really sorry if I am
Answer:
1
0.8
0.4
Step-by-step explanation:
y = 5x
Substituting '5':
5 = 5x
x = 5/5
x = 1
Substituting 4:
4 = 5x
x = 4/5
x = 0.8
Substituting 2:
2 = 5x
x = 2/5
x = 0.4
Answer:
false
Step-by-step explanation:
Answer:
y = -4x +7
Step-by-step explanation:
The 2-point form of the equation for a line can be used.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (-5 -11)/(3 -(-1))(x -(-1)) +11 . . . . fill in values
y = (-16/4)(x +1) +11 . . . . . . . . . . . simplify some
y = -4x +7
Let me walk you through this real quick:
-4x + 9 (10x - 1)
-4x + 90x - 9 (open up the brackets)
90x - 4x - 9
= 86x - 9
