Finding Slope On a coordinate plane, a line goes through points (0, 1) and (4, 2). What is the slope of the line? m =
ivolga24 [154]

Answer:

slope = \frac{1}{4}

Step-by-step explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (4, 2)

m = \frac{2-1}{4-0} = \frac{1}{4}

Find the first 5 terms in the sequence an = 2n - 1
JulsSmile [24]

Answer:

1, 3, 5, 7, 9

Step-by-step explanation:

a_n = 2n - 1

n = 1:

a_1 = 2(1) - 1 = 2 - 1 = 1

n = 2:

a_2 = 2(2) - 1 = 4 - 1 = 3

n = 3:

a_3 = 2(3) - 1 = 6 - 1 = 5

n = 4:

a_4 = 2(4) - 1 = 8 - 1 = 7

n = 5:

a_5 = 2(5) - 1 = 10 - 1 = 9

Answer: 1, 3, 5, 7, 9

masha68 [24]

Answer:

21+12i i hope this will help you

Step-by-step explanation:

(3-4i)(1+5i)-(2-i)

=[3(1+5i)-4i(1+5i)]-(2-i)

=[3+15i-4i-20i²]-(2-i)

=(3+11i-20i²)-(2-i)

opening brackeys

=3+11i-20i²-2+i

=3+11i+1i-20i²-2

as we know that i²=-1

=3-20(-1)-2+12i

=3+20-2+12i

=21+12i
