Answer:
$1125
Step-by-step explanation:
To find percentage of something, we always take the percentage, convert it to decimal by dividing by 100, and then multiply that decimal with the number given.
Here, we want to find 250% of $450. First, lets convert 250% to decimal:
250/100 = 2.5
So, 250% = 2.5
Now we multiply this with $450 to find rent in Manhattan:
2.5 * 450 = $1125
That's a whooping price of $1125 in Manhattan!!
Answer:
b
Step-by-step explanation:
In y=mx+b form, the b is the y-intercept, therefore where the line crosses the y-axis on the graph. In this graph, the line crosses the y-axis at 100. This means that the "b" value is 100. So far, our equation is y=mx+100.
Next, to find m, you go to any other point on the graph and see how much units (rise over run) you went to get there. I picked the point (2,150), You can see that it took me 1 unit up and 2 units to the right to get to that point, leading us to believe the slope is 1/2.
Finally, put everything together and you get the answer of y=1/2x+100 (the letters do not matter) :)
This equation is written in slope intercept form (y=mx+b where m is slope and b in the y intercept).
The m value here is -5 so that is the slope.
The b value here is 0 so the y intercept is at 0.
You can also find this by plugging 0 for the value of x.
y= -5(0)
y= 0
Answer:
3
Step-by-step explanation:
There are a significant number of minus signs here. We can simplify it a bit by factoring out -x:
= -x(x +4)
When we substitute x = -3, we get ...
= -(-3)(-3 +4)
= 3(1)
= 3
