Answer:

-6

Step-by-step explanation:

The y-intercept of a line is the point on the y-axis that is contained in the line. It is the point of intersection of the line and the y-axis.

Every point on the y-axis has coordinates (0, y), where y can be any real number. The x-coordinate of all points on the y-axis is 0. Since you are told your line goes through point (0, -6), then you know that that point is the y-intercept.

The y-intercept is -6.

Answer:

x=58, m<DCB=56°

Step-by-step explanation:

Ok the sum of those two angles should equal 180 degrees so,

2x+8+x-2=180

solve the equation

3x+6=180

3x=174

x= 58

M<DCB=x-2--> 58-2=56

Anni [7]

Hello,

1)
$a_{1}=7$
$a_{2}=7*3$
$a_{3}=7*3^2$

$a_{n}=7*3^{n-1}$

$s=a_{1}+a_{2}+a_{3}+a_{4}+a_{5}=7*(1+3^1+3^2+3^3+3^4)$
$=7*\frac{3^{5}-1}{3-1}$
$=7*242/2=847$

2)

Answer:

A. Nicholas will have to pay less using plan A

B. He will pay US$ 4 less than plan B

Step-by-step explanation:

Let's compare how much Nicholas will pay on internet service in Plan A and plan B, after using it 16 hours and 40 minutes.

Plan A

Up to 10 hours = US$ 6

Every subsequent 1/2 hour: $1

10 hours + 14 (1/2 hour)

Nicholas will pay 6 + 14 * 1 = US$ 20

Plan B

Up to 12 hours = US$ 4

Every subsequent 1/2 hour: $2

12 hours + 10 (1/2 hour)

Nicholas will pay 4 + 2 * 10 = 24
