5)

add 10 to both sides then divide by 5 to isolate the Z

6a) the actual answer is 4F + 12

you don't add 4 you multiply

6b) That is the answer

You see which number is the greatest common factor (GCF)

Im not sure if anyone knows how to do this but if u do could u pleaseee help me with this!!!

Answer:

y = -2x - 5

Step-by-step explanation:

<u>1) Find the slope of the line.</u>

The slope of the original line is the same as the slope of the parallel line.

Slope formula:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

In this case you can choose any 2 set of points on the table.

m = \frac{4 - 2}{-3 - (-2)} = \frac{4 - 2}{-3 + 2} = \frac{2}{-1} = -2

So the slope of the line is -2

<u>2) Use the point-slope formula to find the equation of the line.</u>

Point-slope formula:

y - y_{1}  = m(x - x_{1})

Now plug in the point (0, -5) and the slope -2 into the equation.

y - (-5) = -2(x - 0)

y + 5 = -2(x - 0)

To solve the equation first apply the distributive property.

y + 5 = -2x + 0

y + 5 = -2x

Next, subtract 5 from sides.

y = -2x - 5

You know have your equation in point-slope form!

1oo divided into ratio 3:7
masha68 [24]
 <span>100 is not divisible by 3 when u divide 100 by 3 u get 33.333333...... not 3.33333..... 
the good explanation of your answer is that 0.999999....is equal to 1 
we can prove it by the following way: 
let x=0.9999.... 
then 10x = 9.999999..... 
subtract we will get 10x - x = 9.9999....- 0.99999...... 
which gives us 9x = 9 and therefore x =1 
i hope this will help u with your confusion.......  :)</span><span>
