It should be a 10% tip. To simplify the answer, The decimal moves one space (which would be equal to a tenth) so it’s a 10%
Answer:
15, -26
Step-by-step explanation:
The <em>generic solution</em> to a "sum and difference" problem can be found easily. Let "a" and "b" represent the numbers you seek, and let "s" and "d" represent their sum and difference:
a + b = s
a - b = d
Adding these two equations tells you ...
2a = s + d
a = (s + d)/2 . . . . . . divide by the coefficient of a
You can find "b" several different ways. One way is to subtract the second equation from the first:
2b = s - d
b = (s - d)/2 . . . . . . divide by the coefficient of b
So, the second number can be found from any of ...
- b = s - a
- b = a - d
- b = (s - d)/2
____
For the numbers given here, s=-11, d=41, the two numbers are ...
a = (-11 +41)/2 = 15
b = -11 -15 = -26
The two numbers are 15 and -26.
Answer:
Break the shape up where it needed to be, find the area to the shapes, then add the areas together
Step-by-step explanation:
Answer: D. (0, -4)
=========================================================
Explanation:
If you solve for y, you would get 
. The less than or equal to sign shows we shade below the solid boundary line.
Of the four answer choices mentioned, only (0,-4) is in the shaded region. So this is the only solution.
If we plugged the coordinates into the inequality, we get a true statement as shown below
This is a true statement because -16 is to the left of -8 on the number line. So -16 is smaller.
In contrast, if we tried something like (x,y) = (0,-1), then we see...
Which is not true because -4 is actually larger than -8. Use a number line to see this. So (0,-1) is not a solution. The same can be said about (-2,3) and (-4,0) also.
