Because RS is perpendicular to ST so the slope of line ST is -
Answer: (5,1)
Step-by-step explanation:
Divide both sides of the equation by 3, Eliminate the x's and you should have 6y=6. After solving y to be 1 plug it into one of the equations to find x
4x³ + 10x² - 6x
Factor.
= 2x ( 2x - 1 ) ( x + 3 )
Answer: 1430
Step-by-step explanation: x + y + z = 2680
x = 2z - 100
y = 3z + 80
x + y = 5z - 20
6z - 20 = 2680
z = 450
y = 1430
Solution:
x = 800, y = 1430, z = 450
Hello!
We can double check by plugging in 26 back into x
And it works out!
