Line with a formula of x = a is a vertical line while a line with a formula of y = b is a horizontal line on the other hand. In this case, the graph of x ≤ 4 is the region to the left of the line x = 4 to negative infinity. The graph of y≥ -8 is the region above the line y = -8 <span>to positive infinity.</span>
Answer:
figure 3: 17 cubes.
figure 4: 21 cubes.
figure 5: 25 cubes.
Step-by-step explanation:
Let the nth figure be represented by f(n).
also we are given f(n+1)=f(n)+4.
The number of cubes used in figure 1 i.e. f(1) is 9.
number of cubes used in figure 2 i.e. f(2) is 13
Now we have to find the number of cube used in figure 3, figure 4 and figure 5.
number of cubes in figure 3 i.e. f(3)=f(2)+4=13+4=17.
number of cubes in figure 4 i.e. f(4)=f(3)+4=17+4=21.
number of cubes in figure 5 i.e. f(5)=f(4)+4=21+4=25.
35w + 150 = s
$185, $220, $255, $290, $325
(Add $35 each week for 5 weeks)
The correct answer is 32.5
sorry I can't but maybe if you ask your teacher
