D. y = 9 because it has a complete zero slope while the y-intercept of the equation is 9, so the equation is y = 9.
5. terms are separated by + and - signs
For this case, the first thing you should do is define a variable.
We have then:
t: temperature (degree Fahrenheit).
We write then the inequation that adapts to the problem:
t> = 451
Answer:
an inequality that is true only for temperatures at which books spontaneously catch on fire is:
t> = 451
178+63+37=278 So if we were ESTIMATING it would be around 280.
I hope that this helps!
Parallel lines have the same slope.
So I plug in the -5 and -4
-4 = 1/2(-5) + b
-4 = -2.5 + b
b = -1.5
So I get y = 1/2x - 3/2
