Answer:
125=12x+40
Step-by-step explanation:
Let the number of hours be x
And the total amount be =$125
We already have $40
Hence the expression is
125=12x+40
If we solve for x, the answer gotten is the number of hours
Answer:
<h2>(-1, 17)</h2>
Step-by-step explanation:
The vertex form of a quadratic equation:
<em>(h, k)</em> - vertex
<em>use (a + b)² = a² + 2ab + b² </em><em>(*)</em>
<em>h = -1, k = 17</em>
Step-by-step explanation:
a) The rule is <em><u>multiply the previous term by 6 then add 13</u></em>. So if the 1st term is n0 = -2, then the next term n1 is
n1 = 6n0 + 13
= 6(-2) + 13
= 1
n2 = 6n1 + 13
= 6(1) + 13
= 19
So the sequence goes like
-2, 1, 19
b) Now the sequence is reversed so let's write the terms as follows:
19, 1, -2
The new rule now is <em><u>subtract</u></em><em><u> </u></em><em><u>1</u></em><em><u>3</u></em><em><u> </u></em><em><u>then</u></em><em><u> </u></em><em><u>divide</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>6</u></em><em><u>.</u></em> You can check this as follows:
n0 = 19
n1 = (n0 - 13)/6
= (19 - 13)/6
= 1
n2 = (n1 - 13)/6
= (1 - 13)/6
= -2
Answer is 1290.67. I rounded to the nearest tenth but it goes on.
