Faith wants to use the formula C(f) = 5/9 (f - 32) to convert degrees Fahrenheit, f, to degrees Celsius, C(f). If Faith calculated C (68), what would her result be?

Her results would be 20ºC.

Step-by-step explanation:

The c(f) transformation means that for a Fahrenheit temperature measure, we can realize the conversion to Celsius using the following formula.

c(f) = \frac{5}{9}*(f-32)c(f)=95∗(f−32)

In which f is the temperature measured in fahrenheit and c is the temperature measured in celsius.

If faith calculated c(68), what would her results be

She wants to realize the conversion of 68 fahrenheit to celsius. So

c(f) = \frac{5}{9}*(f-32)c(f)=95∗(f−32)

c(68) = \frac{5}{9}*(68-32) = 20c(68)=95∗(68−32)=20

Her results would be 20ºC.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
