Answer:
D: {0≤x≤20}
R: {0≤y≤200}
Step-by-step explanation:
Domain and range are the possible values of x and y, respectively. For continuous graphs in set notation, inequalities can be used to represent the x and y values. As seen on the graph, the lowest possible x value is 0 and the highest is 20. All of the other values in between are also included. So the inequality 0≤x≤20 expresses all of the values. Additionally, because the circles are closed, the limit values, 0 and 20, are included. Next, the range is found in the same way. The lowest y is 0 and the highest is 200, with the limits included. So, the range inequality is 0≤y≤200.
Answer:
25
Step-by-step explanation:
6(x-5) = 4x+20
6x-30=4x-20
6x25=150-30=120
4x25=100+20=120
Answer:
$834.40
Step-by-step explanation:
Find how many kg Lulu has total by adding 43.50 and 43.50+25 together.
You get 112 kg, and then multiply that by the price per kg, so 112 * 7.45 is 834.40.
Answer:
Last option: Translate each point of the graph of <em>h(x)</em> 3 units left.
Step-by-step explanation:
There are some transformations for a function <em>f(x)</em>. The following is one of these transformations:
If , then the function is shifted "k" units to the left.
Given the function and the function , you can notice that the function <em>m(x)</em> is the function <em>h(x)</em> but shifted left 3 units.
Therefore, you could graph the function m(x) by translating each point of the graph of the function<em> h(x)</em> 3 units left.
This matches with the last option.
