Answer:
Negative, Positive, Negative, Positive
Step-by-step explanation:
1. 18.75 + (-19)
Adding a negative is the same as subtracting. 18.75 - 19 is -0.25 so the first answer is negative.
2. 
+ 
If you convert the fraction in the second term to one with the same denominator (three and 8 10ths), you can see that since 8 tenths is more than 7 tenths, the equation will result in positive 1/10
3. 9.4 + (-
)
3/5 is the same as 6/10 or .60
9.6 is more than 9.4, so the negative is further from zero than the positive.
4. -7 + 7 + 1/2
-7 + 7 is zero. zero + 1/2 is positive 1/2
Answer:
Step-by-step explanation:
Attached is graphed piecewise function.
Take note, if the inequality is a less than or equal to or (more than or equal to), the dots will be solid, otherwise it will be hollow.
Since this is a piecewise function, here is one question you might want to ask yourself:
Does the limit exist when x approaches 4?
Answer:
x = 6
= 8.485
Step-by-step explanation:
In a 45-45-90 triangle, the hypotenuse is times the length of a leg.
So, if you are given the hypotenuse, then divide its length by
x = 12/ = 12/2 = 6 = 8.485
Answer:
I'm pretty sure its D. 11.5
It's 130, any quadrilateral's angles add up to 360 and those numbers add up to 230, 360-230 = 130
