3(y + 4) - (x - 1)
x = 3
y = 2
First plug in the numbers into the variables. Or plug in 3 for "x" and 2 for "y" in the equation.
3(y + 4) - (x - 1)
3(2 + 4) - (3 - 1) Simplify the numbers in the parentheses
3(6) - (2)
18 - 2 = 16
Hello!
All the angles inside a triangle is equal to 180
To find x you can do
180 - 50 - 70 = 60
x = 60
To find y you have to find the other missing angle in the other triangle
180 - 50 - 60 = 70
A line is equal to 180°
To find y you do
180 - 60 - 70 = 50
x = 60 and y = 50
Hope this helps!
Use Moivre Formula to find cube roots of 64(cos219+isin219)
Cubic roots =∛[64(cos219+isin219)] = [64(cos219+isin219)]^(1/3)
= 4[(cos219+isin219)]^(1/3)=4[cos(219)/3+isin219/3)]=
= 1.169 + 3.82 i
Answer: The point (5, 6) would divide the line segment so it is in the ratio of 3:5.
If the ratio of the line segment needs to be 3:5, that means the point will be at the 3/8 distance mark of the line segment. Because there are 8 total parts if the ratio is 3:5 (3 + 5 = 8).
The slope from (2, 9) to (10, 1) is -8/8. So our point would only move 3/8 of that distance. If we multiply -8 and 8 by 3/8, we have -3 and 3.
That means our point must fall 3 and move to the 3 spaces from our starting point of (2, 9). That will put us at (5, 6).
Answer: The correct answer is 5
