2x + -7 +8 = -x+16
2x + 1 = -x +16
2x +1 -1= -x +16 -1
2x+x = -x +x + 15
3x = 15
3x/3 = 15/3
x= 5
2(5) + -7 +8 = -5+16
10 +-7+8 = 11
11=11
Answer: 8 feet
Step-by-step explanation:
Since, the scale of the drawings is 1 inch to 4 feet.
![\implies 1\text{ inch } = 4\text{ feet}](https://tex.z-dn.net/?f=%5Cimplies%201%5Ctext%7B%20inch%20%7D%20%3D%204%5Ctext%7B%20feet%7D)
By multiplying both sides by 2,
![\implies 2\times 1\text{ inch } = 2\times 4\text{ feet}](https://tex.z-dn.net/?f=%5Cimplies%202%5Ctimes%201%5Ctext%7B%20inch%20%7D%20%3D%202%5Ctimes%204%5Ctext%7B%20feet%7D)
![\implies 2\text{ inches} = 8\text{ feet}](https://tex.z-dn.net/?f=%5Cimplies%202%5Ctext%7B%20inches%7D%20%3D%208%5Ctext%7B%20feet%7D)
Thus, the actual length of the table = 8 feet.
Answer:
Suzie's answers are incorrect.
Step-by-step explanation:
x^2+4x-12=2
+12 +12
x^2+4x=14
(if we put Suzie's answer in for x)-
2^2+4(2)=14
4+8=14
Suzie's first answer is incorrect (4+8=12)
Let's try the next one with Suzie's answer
(-6-2)(-6+6)=2
(-8)(0)=2
This answer is also incorrect. (-8*0=0)
Answer:
Step-by-step explanation:
The vertical asymptotes are where the denominator is zero.
x^2 - 9 = 0
x^2 = 9
x = ±√9 = ±3
The vertical asymptotes are at x=-3 and x=3.
