-\left(\dfrac{1}{2}y+\dfrac{1}{4}\right)=-\dfrac{1}{2}y-\dfrac{1}{4}=-\dfrac{1\cdot2}{2\cdot2}y-\dfrac{1}{4}=\dfrac{-2y}{4}-\dfrac{1}{4}=\dfrac{-2y-1}{4}\\\\=-\dfrac{2y+1}{4}

He unit circle has a radius of 1 unit and is centered at the origin. It is dilated so that it passes through the point (4, 0).
Advocard [28]
We know that

if the dilated circle <span>passes through the point (4, 0)
so
the new radius is the distance from the origin to point (4,0)
d=</span>√[(4-0)²+0²]-----> d=√16------> d=4 units

the new radius  is 4 units
original radius is 1 units

[new radius]=[scale]*[original radius]
scale=new radius/original radius-----> scale=4/1-----> 4

the answer is
<span>the scale factor of dilation is 4</span>

If x=-2 and y=6 is a solution of equation 3ax+2by=6, then find the value of b
lana66690 [7]

\text{Substitute the values of x and y to the equation}\\\\x=-2,\ y=6,\ 3ax+2by=6\\\\3a(-2)+2b(6)=6\\\\-6a+12b=6\qquad|\text{add 6a to both sides}\\\\12b=6a+6\qquad|\text{divide both sides by 12}\\\\b=\dfrac{6a}{12}+\dfrac{6}{12}\\\\\boxed{b=\dfrac{1}{2}a+\dfrac{1}{2}}

True or false help me
katrin2010 [14]

Answer:

A. 4/12, C. 1/3

Step-by-step explanation:

2/6 can be divided by 3. Therefore, the fraction is 1/3.

A. 4/12 can be divided by 4. This means the fraction will be 1/3. Because 1/3 is equal to 1/3, this option is correct.

B. 1/2 cannot be simplified. Because 1/3 is not equal to 1/2, this option is not correct.

C. 1/3 cannot be simplified. Because 1/3 is equal to 1/3, this option is correct.

D. 3/8 cannot be simplified. Because 3/8 is not equal to 1/3, this option is not correct.

Determine whether the graph is the graph of a function. A coordinate axis is drawn with an ellipse centered at minus 3, 1.
borishaifa [10]

An ellipse isn't a function -- there will be two y values for some x values. The requirement for a function is that there be exactly one y value for each x value in the domain (and by definition zero y values for xs not in the domain).

Answer: False
