I am looking on the answers, and there is only one case, when a or b or c or d pass: 3|x-3| + 2 = 14. So I assume, that before two is plus. Then:
3|x-3|+2=14 |minus 2
3|x-3|=12 |divide 3
|x-3|=4
From absolute value definition you've got two ways:
x-3=4 or x-3=-4
x=7 or x=-1
And answer d) passes
Answer:
Number of children = 386
Number of adults = 287
Step-by-step explanation:
Let
x = number of children
y = number of adults
x + y = 673 (1)
1.75x + 2y = 1249.50 (2)
From (1)
x = 673 - y
Substitute x = 673 - y into (2)
1.75x + 2y = 1249.50
1.75(673 - y) + 2y = 1249.50
1177.75 - 1.75y + 2y = 1249.50
- 1.75y + 2y = 1249.50 - 1177.75
0.25y = 71.75
y = 71.75/0.25
y = 287
Substitute y = 287 into (1)
x + y = 673
x + 287 = 673
x = 673 - 287
x = 386
Number of children = 386
Number of adults = 287

Answer:
1. zeros of polynomials -- x-values for which the value of the polynomial is zero
2. quartic polynomial -- fourth degree (polynomial)
3. irreducible -- cannot be factored
4. leading coefficient -- coefficient of the term with the highest power
5. end behavior -- the direction of a graph for very large positive and negative values of x
6. leading term -- the term in a polynomial with the highest power
7. cubic polynomial -- third degree (polynomial)
Step-by-step explanation:
These are definitions. They need no explanation.
