Answer: ![x=-\frac{4}{3}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B4%7D%7B3%7D)
Step-by-step explanation:
![2(x)+2(2)=2(\frac{x}{2})-2(x)](https://tex.z-dn.net/?f=2%28x%29%2B2%282%29%3D2%28%5Cfrac%7Bx%7D%7B2%7D%29-2%28x%29)
Remove all those parentheses by multiplying. Note: 2 and 2 cancel out.
![2x+4=x-2x](https://tex.z-dn.net/?f=2x%2B4%3Dx-2x)
Subtract 2x
![4=x-2x-2x](https://tex.z-dn.net/?f=4%3Dx-2x-2x)
Combine like terms;
![4=-3x](https://tex.z-dn.net/?f=4%3D-3x)
Divide by -3
![\frac{4}{-3}=x](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B-3%7D%3Dx)
Rewriting it;
![x=-\frac{4}{3}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B4%7D%7B3%7D)
Answer:
4.95m
Step-by-step explanation:
Let the length of longer and shorter pipe be x and y respectively..
given,
x/y=9/2...(i)
x-1.65=3y ...(ii)
in eqn ii..
x-1.65=3y
or, x/y - 1.65/y = 3
or, 9/2-1.65/y =3
or, 4.5-3 = 1.65/y
or, y=1.65/1.5
•°• y = 1.1m
now,
x/y = 9/2
or, x/1.1 = 4.5
x= 4.5×1.1
•°• x= 4.95m
thus, the length of the longer pipe is 4.95m

Answer:
A. Between 3.0 and 3.5 and between 4.0 and 4.5
Step-by-step explanation:
The zeroes of a function occur whenever a value of x returns zero. To predict where the zeroes lie, determine the interval(s) where the function crosses the x-axis. This occurs when either
goes from a negative value to a positive value or vice versa.
From
and
, the y-values go from 4.0 (positive) to -0.2 (negative), respectively. Therefore, there must be a zero in this interval.
From
and
, the y-values go from -0.8 (negative) to 0.1 (positive), respectively. Therefore, there must also be a zero in this interval.
Thus, the zeros of this function occur between 3.0 and 3.5 and between 4.0 and 4.5, leading to answer choice A.
Answer:
Step-by-step explanation:
In parallelogram, diagonals bisect each other
DP = IP
7x - 8 = 3x
7x = 3x + 8
7x - 3x = 8
4x = 8
x = 8/4
x = 2
NP = YP
3y = 7x - 2
3y = 7*2 - 2
3y = 14 - 2
3y = 12
y = 12/3
y = 4
