Write an equation for the nth term of the arithmetic sequence. Then find a 10

1 answer:

7 0

An=a1+d(n-1)
a1=first term
an=nth term
d=common dffernce

given
first term is -5
it increases by 1

an=-5+1(n-1)
a10
a10=-5+1(10-1)
a10=-5+1(9)
a10=-5+9
a10=4

10th term or a10 is 4

Find the slope of the line that passes through points (2, 8) and (1, 3)

Paha777 [63]

Answer:

Your slope would be 5

Step-by-step explanation:

Since we know 2 points we'd use the formula

$M=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$

$X_{1} = 2$

$X_{2}=1$

$y_{1}=8$

$Y_{2}=3$

So your equation would be

$M=\frac{3-8}{1-2}$

Than you would subtract each of them leaving you with this:

$M=\frac{-5}{-1}$

When you divide the two negative numbers that would leave you with your slope, which is 5.

-5 ÷ -1 = 5

I hope this help.

Answer:

x = 6 y = -9

Step-by-step explanation:

8x +2y = 30

-7x + 2y =24

x= 6

8(6)

48 + 2y =30

-48. -48

2y = -18

÷2. ÷2

y = -9

Find the slope of the line whose equation is 6x - 3y = 12.

kirill115 [55]

You can find the slope by making the equation into slope-intercept form, in other words, solving it for y.

6x - 3y = 12 Subtract 6x from both sides
-3y = -6x + 12 Divide both sides by -3
y = 2x - 4

Slope Intercept form is y = mx + b, where m represents slope. M in your equation is 2, so the slope of the line is 2.
