Answer:

A) ∠BEC is one-half of ∠BAC

B) ∠BEC = 60°

C) ∠BDC = 120°

Step-by-step explanation:

C) arc BDC = 120°

arc BEC = 360° - 120° = 240°

∠BDC = 1/2(240°) = 120°

What do you know about the slopes of lines that are parallel? Explain
Rudiy27

Parallel lines have to have the same slope.  The must stay the same distance apart at all times to be parallel and the only way to do that is to change in exactly the same manner as they move so slope is the change in x over the change in y.  it must be the same

X + y = 3, 4y = -4x - 4<br> System of Equations
alexdok [17]

Answer:

no solutions

Step-by-step explanation:

Hi there!

We're given this system of equations:

x+y=3

4y=-4x-4

and we need to solve it (find the point where the lines intersect, as these are linear equations)

let's solve this system by substitution, where we will set one variable equal to an expression containing the other variable, substitute that expression to solve for the variable the expression contains, and then use the value of the solved variable to find the value of the first variable

we'll use the second equation (4y=-4x-4), as there is already only one variable on one side of the equation. Every number is multiplied by 4, so we'll divide both sides by 4

y=-x-1

now we have y set as an expression containing x

substitute -x-1 as y in x+y=3 to solve for x

x+-x-1=3

combine like terms

-1=3

This statement is untrue, meaning that the lines x+y=3 and 4y=-4x-4 won't intersect.

Therefore the answer is no solutions

Hope this helps! :)

The graph below shows the two equations graphed; they are parallel, which means they will never intersect. If they don't intersect, there's no common solution
