So if x is equal to 1/3, then our equation would be 5/(1/3). When dividing by a fraction, you can multiply by the reciprocal to find the answer, meaning that if you divide by 1/3, you can multiply by 3/1. So your answer would be 15.
5/(1/3)=x
5*3=x
15=x

52 is 12.5 of what number

Ksenya-84 [330]

Well, 12.5 is 25/2.

$\frac { 25 }{ 2 } \times n=52\\ \\ \frac { 2 }{ 25 } \times \frac { 25 }{ 2 } \times n=52\times \frac { 2 }{ 25 } \\ \\ \therefore \quad n=\frac { 104 }{ 25 } =\frac { 100 }{ 25 } +\frac { 4 }{ 25 } =4+\frac { 4 }{ 25 } \\ \\ \therefore \quad n=4.00+0.16=4.16$

State the domain and range for the function f(x) = 2x2 – 7. Show all steps, please.

polet [3.4K]

2x^2 - 7

we can plug any values of x into this The domain is All Real x.

The graph will be a parabola opening upwards with a minimum value when x = 0 and f(x) will be = -7

so the range is f(x) <= -7 or (-∞, -7]
