Step-by-step explanation:
A question is asked with options for answers, but in reality, there is only one question stating that it is correct.
<em>x = 0</em>
<em>Hi there ! </em>
<em>9x + 2y = 10</em>
<em>replace y = 5</em>
<em>9x + 2×5 = 10</em>
<em>9x + 10 = 10</em>
<em>9x = 10 - 10</em>
<em>9x = 0</em>
<em>x = 0 </em>
<em>Good luck !</em>
Answer:
{(a, 1), (b, 1), (c, 1)}, {(1, a), (2, a), (3, a)}, and {(a, a), (b, b), (c, c)}
**All functions are relations, but not ll relations are functions**
In a function, the x values CAN NOT repeat, only y-values can.
56 gray chairs
24 blue chairs
ratio of gray to blue chairs in each row
Gray : blue = 7 : 3
Gray chairs = 7
Blue chairs = 3
Total ratio = 7 + 3
= 10
how many gray chairs and blue chairs will julio use if he sets up a total of 80 chairs
Number of gray chairs = 7/10 × 80
= 0.07 × 80
= 56 gray chairs
Number of blue chairs = 3/10 × 80
= 0.03 × 80
= 24 blue chairs
should be 15...
