Paralalell means that is has the same slope
y=mx+b
m=slope
y=-1x-2
slope=-1

the equation of a line that passes through the point (x1,y1) and has a slope of m is y-y1=m(x-x1)
given
(2,-2) and slope is -1
y-(-2)=-1(x-2)
y+2=-x+2

What is the answer for 4y^2=81
Elena L [17]
<span><u><em>Answer:</em></u>
either y = 4.5
or y = -4.5

<u><em>Explanation:</em></u>
To get the solution, we will need to isolate the y on one side of the equation.
<u>This can be done as follows:</u>
4y</span>²<span> = 81

</span>\frac{4y^2}{4} =  \frac{81}{4}
<span>
y</span>²<span> = 20.25

y = +/- </span>√(20.25)<span>
either y = +</span>√<span>(20.25) = 4.5
or y = -</span>√<span>(20.25) = -4.5

Since there are no restrictions on the value of y, therefore, both answers would be accepted

Hope this helps :)</span>

You pick a card at random. Without putting the first card back, you
Inga [223]

First, we need the probability of picking an odd number.

There are 5 cards in total, and 3 odd cards (3, 5, and 7).

That means that the probability that we'll draw an odd card would be \frac{3}{5}.

Then, we have 4 cards left, and 2 even cards (4 and 6), meaning that the probability that we draw an even card will be \frac{2}{4} or \frac{1}{2}.

To find the probability that these would happen in consecutive draws, we just multiply the probabilities together.

\frac{3}{5}*\frac{1}{2}=\frac{3}{10} or 0.3.

To convert this into a percentage, we multiply the decimal by 100.

0.3*100=30.

So the probability of picking an odd number and then picking an even number is 30%.

Hope this helps!

True or False?<br> 2 is a solution to 8m - 6 &lt; 10<br> True<br> False
Nastasia [14]

Answer:

2 is not a solution

False

Step-by-step explanation:

8m - 6 < 10

Add 6 to each side

8m -6+6 < 10+6

8m < 16

Divide by 8

8m/8 <16/8

m < 2

m must be less than 2

2 is not a solution

3/4+5/6 divided by 2/3 in simplest form show work, please!<br> Thanks!
Nuetrik [128]

Answer:

2 \frac{3}{8}

Step-by-step explanation:

3/4 + 5/6  (lowest common denominator = 12)

= 9/12 + 10/12

= 19/12

19/12 ÷ 2/3  (reciprocate 2/3 to replace division sign by multiplication sign)

= 19/12 x 3/2

= 57/24

= 19/8

= 2 \frac{3}{8}

Hope this helps :)
