I'm sorry I'm not home so I can't tell you the answer to this but what I can tell you is put together the xy and then put together the -13-20. Hope this helps.

The equation of the line that goes through the point (1,5) and is parallel to the line 3x+5y=2 can be written in the form y=Mx+b

Llana [10]

Answer:

$y=-\frac{3}{5}x+\frac{28}{5}$

Step-by-step explanation:

step 1

Find the slope of the given line

we have

$3x+5y=2$

isolate the variable y

$5y=-3x+2\\\\y=-\frac{3}{5}x+\frac{2}{5}$

The slope of the given line is

$m=-\frac{3}{5}$

step 2

Find the equation of the line that goes through the point (1,5) and is parallel to the given line

Remember that

If two lines are parallel then their slopes are equal

therefore

we have

$m=-\frac{3}{5}$

$point\ (1,5)$

substitute in the equation of a line in slope intercept form

$y=mx+b$

$5=-\frac{3}{5}(1)+b$

solve for b

$b=5+\frac{3}{5}\\\\b=\frac{28}{5}$

substitute

$y=-\frac{3}{5}x+\frac{28}{5}$

Which expression gives the number of people who got the mail after 3 weeks ?

Fittoniya [83]

The first week is 10 x 1.4.
The second week is that answer x 1.4 etc.

So you are only multiplying the first week by 10.

{ [ 10 x 1.4) x 1.4] x 1.4}. Since multiplication is commutative, we don’t need the grouping symbols...

10 x 1.4 x 1.4 x 1.4

That s answer A
