Answer:

Step-by-step explanation:

Dilating with a scale factor of 3 centered at the origin means we multiply all the coordinates by 3.

(0,2) maps onto (0,6).
(0,4) maps onto (0,12).
(3,2) maps onto (9,6).
(3,4) maps onto (9,12).

Therefore, the answers are the second option and the sixth option.

Sarah bought 48 pencils and 80 erasers to make gift bags for her friends. each bag will have pencils anf erasers. each bag will

STatiana [176]

Answer:

C. 3 Pencils Per Bag

Step-by-step explanation:

The Greatest Common Factor is 16, meaning Sarah has 16 friends.

She needs to distribute the pencils and erasers evenly.

16 friends x 3 pencils per bag = 48 pencils in total.

16 friends x 5 erasers per bag = 80 erasers in total.

I need help with number 4

Nadusha1986 [10]

$\bf \begin{cases}
\quad3x+2y=-9\\
-10x+5y=-5
\end{cases}$

so hmm the idea behind the elimination, is to make the value atop or below, of either variable, the same but with a negative sign

so hmmm say... we'll eliminate "y"

so... let's see, we have 2y and 5y, both positive
what do we multiply 2y to get a negative -5y, that way, -5y +5y = 0 and poof it goes

well let's see, let's try "k" $\bf 2yk=-5y\implies k=-\cfrac{5y}{2y}\implies k=-\cfrac{5}{2}$

so.. if we multiply 2y by -5/2, we'll end up with -5y

well, let's multiply that first equation then by -5/2

$\bf \begin{array}{rllll}
3x+2y=-9&\qquad\times -\frac{5}{2}\implies &-\frac{15}{2}x-5y=\frac{45}{2}\\\\
-10x+5y=-5&\implies &-10x+5y=-5\\
&&---------\\
&&\frac{-35}{2}x+0\quad=\frac{35}{2}
\end{array}\\\\
-----------------------------\\\\
\cfrac{-35}{2}x=\cfrac{-35}{2}\implies \cfrac{-35x}{2}=\cfrac{-35}{2}\implies x=\cfrac{2}{-35}\cdot \cfrac{-35}{2}
\\\\\\
\boxed{x=1}$

so.. now we know x = 1.... so let's plug that in say hmmm 2nd equation

$\bf -10(1)+5y=-5\implies -10+5y=-5\implies 5y=5\implies\boxed{ y=1}$
