Answer:
solution :
x = 4
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
5*(x-10)-(30-15*x)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
5 • (x - 10) - (30 - 15x) = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
20x - 80 = 20 • (x - 4)
Equation at the end of step 3 :
20 • (x - 4) = 0
Step 4 :
Equations which are never true :
4.1 Solve : 20 = 0
Step-by-step explanation:
Answer: cannot be true because cot∅ is less than zero in quadrant 2.

Apex trigonometry answer
Answer:1, 4, 6
Step-by-step explanation:
Because there are different slopes and it is a linear system there must be 2 separate lines with 1 solution. Also if x=3 both of their y’s are 0 too
Answer:
a
Step-by-step explanation:
a. x=4, y=2
plug it in:
4+20=6 true
b. x=3, y=3
3+3=6
3=3+2
3=5 not equal
c. x=2,y=4
2+4=6
2=4+2
2=6 not true
d. x=6, y=4
6+4=6 not true
6=4+2
