Answer:

Part a)133.3%

Part b)112.5%

Step-by-step explanation:

Part a) We want to express 2 years as a percentage of 18 months.

Make sure both quantities are of the same units.

1 year =12 months

This means

2 years =24 months.

We want to express 24 months as a percentage of 18 months.

The number that comes after of will be in the denominator.

\frac{24}{18}  \times 100\% = 1.333 \times 100\% = 133.3\%

Part 2)

We want to express 225mm as a percentage of 20cm.

10mm= 1 cm

This means

200mm= 20cm

We want to express 225mm as a percentage of 200mm

=  \frac{225}{200}  \times 100\% = 112.5\%

Given: f(-x) = x - 7 and h(x) = 2x + 3
Nitella [24]

Answer:

if given f(-x)=x-7,  then f(h(x))=-2x-10

or  if given f(x)=x-7, then f(h(x))=2x-4

Step-by-step explanation:

if given f(-x)=x-7

f(-x)=x-7 => f(-(-x))=(-x)-7  =>f(x)= -x-7

f(h(x))=f(2x+3)= -(2x+3)-7 = -2x-3-7 = -2x-10

if given f(x)=x-7

f(h(x))=f(2x+3)=2x+3-7=2x-4
