Answer:
Step-by-step explanation:
1) 5xy - xy + 2x - 13x + 10xy - 8x =<u> 5xy - xy + 10xy</u> +<u>2x - 13x - 8x</u>
Combine like terms
= (5 -1 +10)xy + (2-13-8)x
= 14xy + (-19x)
= 14xy - 19x
2) -6c - (-6c) - (+6c) = -6c + 6c - 6c
= (- 6 + 6 - 6)c
= -6c
3) 0x - 22x - 4(2x) = 0x - 22x - 8x = -30x
Answer:
t ≥ 0.2c
Step-by-step explanation:
Her tip is at least 20% of the cost of the meal, so her tip is greater than or equal to 20% of the cost of the meal
tip ≥ 20% of the cost of the meal
t ≥ 20% of c
Another way of writing "20% of c" is multiplying the two values, so we have
20% of c = 20% * c
t ≥ 20% * c
To convert from a percentage to a decimal, we can divide the percentage by 100. Here, we have
20% = 0.2
t ≥ 0.2 * c
<u>Statement </u> <u>Reason</u>
1. AB = x + 16 1. Given
BC = 4x + 11
AC = 77
2. AB + BC = AC 2. Segment Addition Postulate
3. x + 16 + 4x + 11 = 77 3. Substitution Property
4. 5x + 27 = 77 4. Simplification <em>(added like terms)</em>
5. 5x = 50 5. Subtraction Property of Equality
6. x = 10 6. Division Property of Equality
7. AB = 10 + 16 7. Substitution Property
8. AB = 26 8. Simplification <em>(added like terms)</em>
Answer:
The average rate of change of g(z) =4x^2_5 between the points( -2,11) and (2,11) is 0.
Step-by-step explanation:
Given a function y, the average rate of change S of 
in an interval 
will be given by the following equation:
In this problem, we have that:
Between the points( -2,11) and (2,11).
So 
So
The average rate of change of g(z) =4x^2_5 between the points( -2,11) and (2,11) is 0.
Find n first.
n+10= 40
Subtract 10.
n= 30
Plug in n.
30-25= 5
The answer is 5.
I hope this helps!
