Check the picture below.
so, if we add all the arcs provided, we have a total of 153° + 60° + 53°, which gives us 270°.
keeping in mind that a circle has a total of 360°, the shaded region has to be a sum of 360° - 270°, or 90°.
now, notice the tickmarks on those angles in the graph above, meaning those two angles are twins, and 90°/2 is 45°, so each of those twins is 45°.
arcYW = 60° + 45°.
The distance formula is the radical (x2-x1)2 + (y2-y1)^2. So for the x value, you subtract (-1) from 8. But be careful. It’s not 8-1. IT’S 8-(-1). Which x value, 9 should be squared. Which it is 81. The y value, you subtract 0 from 6. Which you should have 6 as your y value. Then, again you have to squared it. So, 6^2 is 36. Now that you have both of your x and y value, you have to subtract them again. In order to subtract, you subtract the y value from the x value. In other words, 81-36. The answer should be 45. But 45 is irrational. Because it can’t be rational under the radical form. So to simplified it, you have to find a number that is rational enough to get out from the inside of the radical form. The only number that would work is 9 and 5. So rad 9 is rational because it could escape from the inside. Which it’s 3 once it’s out. But, 5 is irrational and can’t go out. As a result, the answer is 3 rad 5. Or the 3 is outside of the radical form and 5 is the inside.
3n/2-n/4=7n+4/12
12 (3n/2-n/4=7n+4/12) factored in 12 to both sides to get rid of fractions
12 (3n/2)-12 (n/4)=12 (7n)+12 (4/12) distributive power
36/2n-12/4n=84n+48/12
18n-3n=84n+4 simplified
15n=84n+4
15n-84n=84n-84n+4 addition property
-69n=4
-69/-69n=-4/69 division property
n=-4/69
Solution : n=-4/69
Answer:
x = 12, y = 1
Step-by-step explanation:
y - x = -13
-4x + 3y = -51
Find y.
y = -13 + x
Plug y into 2nd equation
-4x + 3y = -51
-4x + 3(-13 + x) = -51
-4x + -39 + 3x = -51
-x = -12
x = 12
y = -13 + 12
y = -1
