Answer:
(-♾, ♾)
Step-by-step explanation:
A quadratic can accept any real x value. So the domain is All Real Numbers. This in interval notation is
(-♾, ♾)
This is read as negative infinity to positive infinity
To change a fraction to a decimal, simply divide the numerator by the denominator. The numerator is the top part of the fraction, while the denominator is the bottom part of the fraction.
4 ÷ 5 = 0.8
Thus,
<span>as a decimal would be 0.8</span>
You can find the slope of a line by having two points. In this case we have 5 different point so we pick two.
so for the first one I will pick (2,17) and (7,37)
we use (y2-y1) / (x2-x1) this is rise over run
plug and chug to get slope.
(37-17)/(7-2)= 4
now use point slope using one of the point that we used to find the slope
y−b=m(x−a<span>) or y-y1 = m (x-x1)
plug and chug again
m=4 ............ point (2,17)
y- 17 = 4 (x- 2)
y= 4x +10
hope this helps

$9 per hour
the answer is 9h because if you tried to find out how much she earns after 10 hours you would do 9*10=90 not the other one
