Answer:
(6,2)
Step-by-step explanation:
When solving a system of simultaneous equations, we want to see where the graphs intersect.
2x+5y =22 is the red line
x+y = 8 is the green line
They intersect at a point
The point is x=6 y=2

Answer:
No
Step-by-step explanation:
if you see any duplicates or repetitions in the x-values, the relation is not a function.
Answer:
x > 2
Step-by-step explanation:
First simplify the bracket....to give you...x + 2...then
; 4x + x + 2 > 12....
; 5x + 2 > 12
; 5x > 12 - 2.....then gives you...5x > 10...then divide both sides by 5
then gives you....; x > 2
Answer:
N/A
Step-by-step explanation:
Get the Desmos graphing calculator app. it is very helpful when graphing and needing to be able to compare functions
Use the formula sin A/ side a = sin B/side b. sin 12/8=sin B/10. Now cross-multiply, and with your calculator in degree mode, 10 sin 12 = 8 sin B. The left side comes out to 2.079, so you need to divide both sides by 8 to get sin B alone. Now the equation is .2599=sin B. Use the inverse function on your calculator sin^-1(.2599)=15.06
