erica [24]
To find the amount of votes that the candidate that won received multiply 360 by .8.

360*.8 = 288

This means the winning candidate received 288 votes.

I need help on c and d please
Dennis_Churaev [7]

A

We can't really do this without seeing 28, but I can give you an educated guess. The best way for me to proceed is to solve c.

The conjecture is that x = a + b. You should always find that to be true. C is the clincher.

Here's how you do that.

x + c = 180o That's true because all straight lines have 180o. If two angles make up the straight line that means that they are always equal to 180o So x + c = 180o

Now we move to the next step. All triangles also have 180o. That means that a + b + c = 180o

So we have two conditions that equal 180o. Equalities can be equated to one another.

a + b + c = x + c Subtract c from both sides.

a + b = x.

Study what has happened. Put in mathese, the two remote interior angles equal the exterior angle, which is what you are trying to prove.

Summary

a cannot be solved without 28

b you should say that the two remote angles (a and b) will always total x

c The proof is provided for you.

A straight line has an x intercept -2 and passes through the point (-4,6) Find its equation
Illusion [34]
The x-intercept is the point where the line crosses the x-axis. That point has a y-coordinate of 0. The coordinates of the x-intercept are (-2, 0). You are also given point (-4, 6), so you have two points on the line.

You can use the two-point form of the equation of a line to find its equation.
The two points are (x_1, y_1) and (x_2, y_2)

y - y_1 = \dfrac{y_2 - y_1}{x_2 - x_1}(x - x_1)

y - 0 = \dfrac{6 - 0}{-4 - (-2)}(x - (-2))

y = \dfrac{6}{-2}(x + 2)

y = -3(x + 2)

y = -3x - 6
