Answer:
C) (6,2)
Step-by-step explanation:
Rewrite equations:
y=x−4;x+2y=10
Step: Solve y=x−4for y:
y=x−4
Step: Substitute x − 4 for y in x+2y=10:
x+2y=10
x+2(x−4)=10
3x−8=10(Simplify both sides of the equation)
3x−8+8=10+8(Add 8 to both sides)
3x=18
3x
3
=
18
3
(Divide both sides by 3)
x=6
Step: Substitute6forxiny=x−4:
y=x−4
y=6−4
y=2(Simplify both sides of the equation)
Hope this helps!

5.50 Each
Step-by-step explanation:
Answer: -2x+7y+16
Step-by-step explanation:
1. Distribute 2 through the parentheses
- 4x+6y+3(5-2x)+1+y
- 4x+6y+15-6x+1+y
2. Collect like terms
- -2x+6y+15+1+y
- -2x+7y+15+1
- -2x+7y+16
3. Solution, -2x+7y+16
Answer:
its 10
Step-by-step explanation:
10 times 1 is 10
Answer:
The rule is +2
This is the 194th term
Step-by-step explanation:

2x + 1 = 389
2x = 388
x = 194
194* 2 + 1 = 389
