The Length of Segment QS is 17 units.
Answer:
ages of the twins are 11 years
Step-by-step explanation:
let the age of the twins each be X
Age of the older sister = X+9
This current year;
(X)(X)(X+9) - (X+X+X+9) = 2378
X³+9X² - 3X-9 = 2378
Solving the polynomial
X = 11
Hence ages of the twins are 11 years
Since both equations are solved for y, use substitution.
y = 2x + 3
y = -x - 5
2x + 3 = -x - 5
3x + 3 = -5
3x = -8
x = -8/3
Now substitute -8/3 in for x in the original first equation, and solve for y.
y = 2x + 3
y = 2(-8/3) + 3
y = -16/3 + 9/3
y = -7/3
Solution: (-8/3, -7/3)
Answer:(3,1.5)
Step-by-step explanation:
When you do rise over run you need to go to either the left or right in this case it’s the right and after you need to go up or down in this case down so to get to where the points meet you need to go 3 units to the right and 1.5 units up which will get you (3,1.5)
