Hey there!

The answer to your question is $45\frac{9}{10}$

We can find this by simply plugging in the "r" value into the given equation.

46 + $\frac{1}{5}$ ( $\frac{-1}{2}$ )

Now we evaluate the equation:

46 + $\frac{1}{5}$ ( $\frac{-1}{2}$ )

46 + $\frac{-1}{10}$

$45\frac{9}{10}$

Hope this helps and have an amazing day!

Answer:

$45\frac{9}{10}$ or $45.9$

Step-by-step explanation:

All we have to do here is substitute the given value of $r$ into the given expression. Therefore, after substituting $r=-\frac{1}{2}$ into $46+\frac{1}{5}r$ , we get:

$46+\frac{1}{5}r$

$= 46+\frac{1}{5}*(-\frac{1}{2} )$ (Substitute $r=-\frac{1}{2}$ into $46+\frac{1}{5}r$ )

$=46-\frac{1}{10}$ (Multiply)

$=45\frac{9}{10}$ or $45.9$ (Simplify)

Hope this helps!

Parallelogram JKLM has vertices J(-1, 6), K(0, 9), L(6, −3), and M(3, −3). What is the coordinates of the image if the parallelo

Digiron [165]

Answer: $(\dfrac13,-2),\ (0,-3),\ (-2,1),\ (-1,1) .$

Step-by-step explanation:

Transformation rule for dilation:

$(x,y)\to(kx,ky)$ , where k = scale factor

Given : Scale factor = $-\dfrac13$

Parallelogram JKLM has vertices J(-1, 6), K(0, 9), L(6, −3), and M(3, −3)

Vertices after dilation:

$(-1,6)\to(-1\times\dfrac{-1}{3},6\times\dfrac{-1}{3})=(\dfrac13,-2)$

$(0,9)\times(0\times-\dfrac13,9\times-\dfrac13)=(0,-3)$

$(6,-3)\to(6\times-\dfrac13,\ -3\times-\dfrac13)=(-2,1)$

$(3,-3)\to (3\times-\dfrac13,\ -3\times-\dfrac13)=(-1,1)$

Hence, the coordinates of the image if the parallelogram = $(\dfrac13,-2),\ (0,-3),\ (-2,1),\ (-1,1) .$

Please help! I'll also give you a brainlist.

Range: (-infinity, 4]
the ] signifies that the four is included in the range, rather than ) which means reaching but never approaching. this is why we use ( ) for - and + infinity, cause it can never be reached.

minimum: (-infinity, infinity)
keep it in same format as you have for the maximum

increasing
the interval -infinity

Effectus [21]

Answer:

When the scale factor between two circles is “x” the scale factor between the radius is also “x” and the scale factor of the area is “x^2"

this is only one possible answer. For example, instead of radius, you could have put diameter or circumference.

Simplify. 7/8+(−2/3) divided by 5/6

Sedaia [141]

7/8+(−2/3) divided by 5/6

(7/8 - 2/3)/(5/6)
=(21/24 - 16/24) / (5/6)
= (5/24) / (5/6)
= 5/24 * 6/5
= 6/24
= 1/4
