Answer:

See the graph of the given linear equation shown below.

Explanation:

Given the linear equation : x+y = -2

We make a table for values of x and y;

x y = -2-x

0 -2

-2 0

1 -3

Now, plot these three points (0, -2) , (-2, 0) and (1, -3) on the coordinate plane.

You can see the graph as shown below.

Find the factored form of 18n+12

Black_prince [1.1K]

Factored: 6(3n+2)

6 is the greatest common factor of 18n and 12 so you change it to distributive property by factoring it to 6(3n+2)
if you distribute 6(3n+2) you get 18n+12

What is the equation of the axis of symmetry for the parabola y = 2/3 (x - 2)^2 - 5?

katovenus [111]

For
y=a(x-h)^2+k

the axis of symmetry is x=h

so
y=2/3(x-2)^2-5
the axis of symmetry is x=2

Q20-23 with steps pls

just olya [345]

20: Let $x$ be the amount of money. If this amount is shared between 8 people, each person will get x/8 dollars. But there actually are 6 people, so everyone is getting x/6 dollars. We know that this difference results in 30 dollars more, so we have

$\dfrac{x}{6}=\dfrac{x}{8}+30 \iff \dfrac{x}{6}-\dfrac{x}{8}=30$

Rearrange the left hand side as

$\dfrac{4x-3x}{24}=30$

And multiply both sides by 24 to get

$x=720$

21: Let $M$ and $J$ be the number of marbles owned by Mike and Judy, respectively. At the beginning, we have

$M=3J+11$

If they both get 9 more marbles, Mike will have $M+9$ marbles, and Judy will have $J+9$ marbles. So, we have

$M+J+18=93 \iff M+J=75 \iff M=75-J$

Plug this value in the first equation and we have

$75-J=3J+11 \iff 4J=64 \iff J=16$

And we deduce

$M=16\cdot 3 + 11=59$

So, the difference is

$M-J=59-16=43$

22: Let $x,y,z$ be the number of $10, $20 and $50 coupon, respectively. We're given:

$\begin{cases}x=2y+3\\z=\frac{1}{2}y\\x+y+z=38\end{cases}
We can write the third equation by substituting the expressions for x and z:
[tex]x+y+z=(2y+3)+y+\left(\dfrac{1}{2}y\right)=38$
