-12.3f= -73.8
F multiplied by -12.3, you just put both thing down together and the equal sign and -73.8 the multiplication sign isn’t really necessary.
Answer:
x=52, y=137
Step-by-step explanation:
Answer:

Step-by-step explanation:
Given
See attachment for graph
Required
The domain of the graph
To do this, we simply write out the range of value of the x-coordinate.
From the attached graph, the x values are:
i.e. from 0 to 40 (both inclusive)
So, the domain is:

TTese are all parabolas whose axis of symmetry is the y axis. The negative coefficient means they open downwards and the positive mean they open upwards. The higher the absolute value of the coefficient is the greater the slope, so 2x^2 will be steeper than x^2 and -4x^2 will be steeper than - 2x^2.
So h(x) and j(x) are the answers.
95/100 = 0.95 <== if she missed 5 out of 95, then she got 95 out of 100
