Answer:

$\boxed{\bold{Both \ Sides \ Are \ Equal, \ True \ For \ All \ x}}$

Step By Step Explanation:

Expand $\bold{5\left(-3x-2\right)-\left(x-3\right): \ -16x-7}$

Expand $\bold{-4\left(4x+5\right)+13: \ -16x-7}$

$\bold{-16x-7=-16x-7}$

Add 7 To Both Sides

$\bold{-16x-7+7=-16x-7+7}$

Simplify

$\bold{-16x=-16x}$

Add 16x To Both Sides

$\bold{-16x+16x=-16x+16x}$

Simplify

$\bold{0=0}$

Both Sides Are Equal, True For All x

Choose the correct conic section to fit the equation.

erik [133]

Answer:

Circle

Step-by-step explanation:

The given equation is $x^2+y^2=16$

We know the standard equation of a circle is given by

$(x-h)^2+(y-k)^2=r^2$

Where, (h,k) is the center of the circle and r is the radius.

We can rewrite the given equation in this form

$(x-0)^2+(y-0)^2=4^2$

Hence, the center of the circle is (0,0) and radius is 4.

Thus, the given equation represents a circle.

Where are the Cookies? Mrs. Goodwin left a tray of eookies on the counter early one morning. Dean walked by before lunch and dec

dsp73

24 cookies

dean ate 8 cookies

elise ate 4 cookies

clark ate 6 cookies

Step-by-step explanation:

i am pretty sure this is correct

make a diagram of a circle with twelve spots

change 1/3 to 4/12, so color in 4 spots for dean

multiplie 1/4 times 8/12 ( the remaining spots), color in that number of spots for elise

do the same with 1/2, color in the amount of spots for clark

you will have 3 spots left, meaning each spot is worth 2 cookies

multiplie the number of spots times two to get your answer for each person

What is the distance between A (-4,2) and B (12,4)

My name is Ann [436]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points}
\\\\
A(\stackrel{x_1}{-4}~,~\stackrel{y_1}{2})\qquad
B(\stackrel{x_2}{12}~,~\stackrel{y_2}{4})\qquad \qquad
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
AB=\sqrt{[12-(-14)]^2+[4-2]^2}\implies AB=\sqrt{(12+14)^2+(4-2)^2}
\\\\\\
AB=\sqrt{26^2+2^2}\implies AB=\sqrt{680}$
