Answer:
y = 0.6x
Step-by-step explanation:
Look what happens as we move from point (4, 2) to point (8, 4). The x coordinate increases by 4 and the y coordinate by 2. Thus, the slope of the line representing Relationship A is m = rise / run = 2/4, or 0.5.
The only one of the four possible answers that could be correct is y = 0.6x, which has a greater rate (slope) than does the given line (m = 0.5).
Hello there!
To solve for this problem, you need to solve for x. To do that, you must isolate the variable (x) on one side of the equation.
We have the following equation:
-9 = x - 14
To isolate x, we need to get rid of -14.
So, to get rid of -14, we need to cancel it out by implementing a number of equal but opposite value. The opposite of -14 and is of equal value is 14.
Add 14 to both sides.
-9 + 14 = 5
-14 + 14 = 0
We are now left with the following solution:
x = 5
I hope this helps!
Answer:
I don’t see a graph
Step-by-step explanation:
Answer:
150
Step-by-step explanation:
First a diagram which looks like a 12 sided figure where all the sides are equal.
Now draw 2 consecutive radii.
There are 12 such triangles in a 12 sided polygon.
These triangles have an apex angle of 360 / 12 = 30 degrees.
The other two angles making up the triangle are both equal. Therefore x + x + 30 = 180
2x = 150
x = 75
But 75 is 1/2 of the interior angle. There are 2 such angles making up the interior angle 75 + 75 = 150

Step-by-step explanation:
Since Point A is included in the altitude, we must have an equation that has to make Point A a solution set in the equation.
Pluging in and chugging Point A into each equation should tell us what the equation should be.
<u>Option 1</u>
x - y = 1
-3 - 2 = 1
-5 ≠ 1
We see here that -5 does not equal to 1. Therefore option 1 is incorrect.
<u>Option 2</u>
x + y = -1
-3 + 2 = -1
-1 = -1
We see here that -1 does equal to -1. Therefore option 2 is correct.
<u>Option 3</u>
x + y = 1
-3 + 2 = 1
-1 ≠ 1
We see here that -1 does not equal to 1. Therefore option 3 is incorrect.
<u>Option 4</u>
x - y = -1
-3 - 2 = -1
-5 ≠ -1
We see here that -5 does not equal to 1. Therefore option 4 is incorrect.
We can also graph the points and eyeball it. Doing so, we should see that our y-intercept is around -1 and our slope is also negative. Option 2 would be the best fit.
