Easy,
write the coordinates out in pairs:
x= hours
y= earnings
(1,10)
(2,20)
(3,30)
(4,40)
(5,50)
Now it makes it much easier to see the increase,
After 1 hour of working she has made $10
After 2 hours of working she has made $20
<span>After 3 hours of working she has made $30
</span>
And so on,
that being said it's easily seen that she is getting paid $10
Thus the unit rate is $10.
She should have subtracted 12 instead of adding.
x+12=31
-12=-12
x=19
Answer: -1-1.6n
Step-by-step explanation:
To simplify this expression, we combine the number terms, 5 and -6, to get -1. Then we combine the terms with n, to get -1.6n.
Our final answer is -1-1.6n
Answer:
D. Min (3, -4)
Step-by-step explanation:
This curve is a parabola, the graph of a quadratic function. It has a kind of u-ish, v-ish shape. Right there at the bottom, where the curve appears to be making a u-turn, is the vertex. That point is at (3,-4).
Also, it is a low point of the curve, which makes it a minimum of this upward opening parabola. Sometimes this curve can be flipped upside down, in which case it would have maximum.
But this one has a minimum at (3,-4)
