9.18 --> 9
21x9 is 189, thus the estimated product is 189.
Let me know if this helps!
Set the 2x - 1 equal to 9 then work backwards. 2x - 1 = 9 Nine minus one is eight divided by two is four. X = 4
Answer:
y = -x + 8
Step-by-step explanation:
The equation can be written as;
y = mx + b
where b is the y-intercept
From the diagram , b= 8
y = mx + 8
To get m, substitute (8,0 ) into the equation
0 = 8x + 8
x = -8/8
x = -1
So the full equation is;
y = -x + 8
