Answer:
3=5(-3)+2(9)
Step-by-step explanation:
If x=-3 and y=9 the steps would be:
3=5(-3)+2(9)
3=-15+18
3=3
Hope this helped! xx
(5, 8) has two positive numbers. In case you don't remember
Quadrant I: Both positive
Quadrant II: Negative x value, Positive y value
Quadrant III: Both negative
Quadrant IV: Positive x value, Negative y value
5 and 8 are Both Positive, therefore it is in quadrant I.
Answer:
x^2 - 6x - 55 = 0
using calculator apply mode 5 3 and write nmbrs
1 , -6 , -55
answers must be 11 and -5
Answer:
∠ BOC = 40°
Step-by-step explanation:
∠ AOC = 90° , then
5x + 2x + 20 = 90
7x + 20 = 90 ( subtract 20 from both sides )
7x = 70 ( divide both sides by 7 )
x = 10
Then
∠ BOC = 2x + 20 = 2(10) + 20 = 20 + 20 = 40°
