Im not sure about this one but i think x is 60 since the line Ed basically bisects the angle E which also bisects the line GH in half so that 62=x+2 and then solve for the equation

A line passes through tge points (1,-3) and (4,6) what is the zero of this line ?

Maru [420]

Answer:

Step-by-step explanation:

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

We are given the points (1,-3) and (4,6). Substituting:

$\displaystyle y+3=\frac{6+3}{4-1}(x-1)$

Operating:

$\displaystyle y+3=\frac{9}{3}(x-1)$

$y+3=3(x-1)$

The zero of this line can be found by making y=0 and solving for x:

0+3=3(x-1)

3=3x-3

Adding 3:

6=3x

Solving:

x = 2

The zero of the line is (2,0)

Please help because no one been answering my questions

Answer:

$BC = 8 \sqrt{2}$

Step-by-step explanation:

$\sin(45) = \frac{opposite}{hypotenuse}$

$\sin(45) = \frac{8}{BC}$

$(BC) \sin(45) = \frac{8}{x} (BC)$

$(BC) \sin(45) = 8$

$\frac{(BC) \sin(45) }{ \sin(45) } = \frac{8}{ \sin(45) }$

$BC = \frac{8}{ \sin(45) }$

$BC = 8 \sqrt{2}$

The formula c = 5p + 210 relates c, the total cost in dollars of hosting a birthday party at a skating rink, to

Lesechka [4]

It would be 31 because if they are willing to spend 365 on the party then you’d replace the c with 365 and then subtract 210 from 365 and then divide 5 to get the variable by itself
