Answer:
12a. 45+0.5x+2x+x = 150
12b. the three unknown sides are 30ft, 60ft, and 15ft.
Step-by-step explanation:
12a. the fence is 150ft. so
45+0.5x+2x+x = 150
12.b solve the equation from 12a.
45+0.5x+2x+x = 150
7x/2 = 105
7x = 210
x= 30
0.5(30) = 15ft
2(30)=30ft
x= 30ft
the three unknown sides are 30ft, 60ft, and 15ft.
Answer:
AC = 3x + 3 (answers may vary)
Step-by-step explanation:
AB = 6x + 2
Answers may vary for this question,
Let's say that,
B = 4x + 1
So that means that,
A = 2x + 1
BC = 5x + 3
Since we chose
B = 4x + 1,
we must subtract B from BC to get C,
C = x + 2
Now we add A and C to get AC,
A = 2x + 1
C = x + 2
AC = 3x + 3
The function which can represent the height, y according to the horizontal distance, x is; Choice A; y = –3/4x + 36.
Which function can represent the height, y, according to the horizontal distance x, from the top of the stairs?
According to the task content; The railing will begin at a height of 36 inches and follow the slant of the stairs. On this note, it follows that the y-intercept of the function is 36.
Additionally, since the railings decreases 9 inches for every 12 horizontal inches, it follows that the slope, m = -9/12 = -3/4.
On this note, the required function is; A.y = –3/4x + 36
