The domain and the range of a function are the set of input and output values of the function
The domain of the function is [0,200], and the range of the function is [-50,950]
<h3>How to determine the domain and the range</h3>
The function is given as:
f(x) = 5x - 50
Set f(x) to 0, to calculate the domain
When x = 0, we have:
f(0) = 5 * 0 -50
f(0) = -50
When x =200, we have:
f(200) = 5 * 200 - 50
f(200) = 950
This means that, the domain of the function is [0,200], and the range of the function is [-50,950]

Total portions are
5+4+3
12
One portion,
4860 / 12
405 So
5 : 4 : 3
5*405 : 4*405 : 3:405
2025 : 1620 : 1215
If you divide them you get 0.1
HAHAHAHAH your bad
Step-by-step explanation:
Answer:
132 cm²
Step-by-step explanation:
Consider the shape as a trapezoid with a rectangle added on top.
The area of the trapezoid is (7+19)/2 × 8 =104
The area of the rectangle is 7×4 = 28
Add the two areas: 104+28= 132
OR consider the shape as a tall rectangle with the two triangles added to the sides.
The area of the rectangle is 7(4+8) = 84
The area of the triangles is 8(19-7)/2= 48
[Each triangle is 24 cm²]
Add those areas
84+48=132
Same result: 132 cm²
