what is the equation of the line in point slope form that goes through (-2,-1) and is perpendicular to y=5x+3?

Point slope form is $y-y1=m(x-x1)$

Since we have to write the equation of a perpendicular line we will have to use the slope that is opposite and reciprocal.

$y - (-1) = - \frac{1}{5} (x - (-2))$
$y + 1 = - \frac{1}{5} (x + 2)$

Hope this helps :)

The first term of an arithmetic sequence is -5, and the tenth term is 13.

Nitella [24]

Answer:

The common difference is 2

Step-by-step explanation:

The formula for an arithmetic sequence is

an = a1+d(n-1)

a1 = -5

a10 = 13

Substituting n=10 a10=13 and a1 =-5

13 = -5 +d (10-1)

13 = -5 +9d

Add 5 to each side

13+5 = -5+5 +9d

18 = 9d

Divide each side by 9

18/9 = 9d/9

2 =d

What is a sequence of transformations?

MrMuchimi

Answer:

B, Two or more translations, reflections, or rotations that map a pre-image to its image

Step-by-step explanation:

A sequence is an order of events. So we want to look for an answer that includes an order of events. This already knocks out C and D.

Now we are left with A and B. It is not A because the sequence does not require all three rigid transformations.

It is B because we need at least two transformations to have an order of events and these order of events need to map the image to its pre-image. But also because the other ones were wrong. Hope this helps!

X=9y<br> 5x+3y= -48<br> What does x equal?<br> What does y equal?

Anon25 [30]

you can plug the x value (9y) into the second equation

5(9y) + 3y = -48

45y + 3y = -48

48y = -48

y = -1

x = 9(-1)

x = -9
