Phone card = $20
You need to minus 17.92 from 20 = $2.08
$2.08 / 0.13 = how many minutes
= 16
<span>We say a function is undefined when the value gotten isn't present in the domain of the function, like division by a 0 denominator or 0 to the power of 0. That said, we would like to find out whether at each point in the domain, the two points x = 3 and x = 4 exist i.e we don't end up with the indeterminate form. Okay at x =3, we have f(3) = (3-6) (3+3) (3+4)/(3+6) (3-3) (3-4) = (-3) (6) (7) / 0 which is undefined. We don't have to show for x =4 since "4" is negative in the denominator. We would also end up with an undefined function. So, yes, Angie is right.</span>
Answer:
<u>The last step in solving this equation was D. Divide both sides of the equation by 3</u>
Step-by-step explanation:
For finding the solution, let's solve the equation:
7/8 = 3x - 5/11
-3x = - 5/11 - 7/8
-3x = (-40 - 77)/88 (Subtracting at the right side of the equation)
-3x = -117/88
3x = 117/88 (Multiplying by - 1 at both sides of the equation)
x = (117/88)/3 (Dividing by 3 at both sides of the equation)
<u>x = 117/264</u>
<u>The last step in solving this equation was D. Divide both sides of the equation by 3</u>
Answer:
1:2
Step-by-step explanation:
1:n to 6:12
Take the second term 6:12
Divide each term by 6 to get to 1
6/6 =1
Divide all terms by 6
6/6 : 12/6
1:2
n=2
