Four friends ordered a pizza.Christopher ate 1/5, Emma ate 0.27, and Jamie ate the rest.what percent did Jamie eat?

DENIUS [597]

Percent means parts out of 100

so
1/5=0.20
chris+em+jam=100%=1
0.20+0.27+jam=1
0.47+jam=1
minus 0.47 both sides
jam=0.53
jam=53/100
jam=53%

How do I find out what f(x) is if the graph defines h(x)

const2013 [10]

Answer:

f(x) = $\frac{-h(x) + 7}{4}$

Step-by-step explanation:

h(x) is defined by the formula,

h(x) = -4f(x) + 7

If the graph attached is of the function 'h' and we have to find the function 'f',

h(x) - 7 = -4f(x)

4.f(x) = -h(x) + 7

f(x) = $\frac{-h(x) + 7}{4}$

Therefore, function 'f' will be defined by,

f(x) = $\frac{-h(x) + 7}{4}$
