Answer:
About 6 chairs
Step-by-step explanation:
75x=22.50+420
75x=442.5
x=5.9
So about 6 chairs
In scientific notation it would just be 3.06 x 0, it is the same thing as the regular notation.
Answer: y > 2x + 1
Step-by-step explanation:
In the graph first, we can see two things:
The line is not solid (so the values in the line are not included), and the shaded part is above, so we will be using the symbol:
y > f(x)
Now, in the line we can see that when x = 0, y = 1.
So the linear equation must be something like:
f(x) = a*x + 1
The only one that has an y-intercept equal to 1 is y > 2x + 1
The answers is the picture I posted. I did in khan academy and it was right.
