Answer:
6+10+14+18+22+26
Step-by-step explanation:
Let n =1
4(1) +2 = 6
Let n = 2
4(2) +2 = 8+2 = 10
Let n =3
4(3) +2 = 12+2 = 14
Let n= 4
4*4+2 = 16+2=18
Let n=5
4*5+2 = 20+2 =22
Let n=6
4(6)+2=24+2=26
Sum these together
6+10+14+18+22+26
Answer:
option C.
Step-by-step explanation:
we have
System A
---> first equation system A
----> second equation system A
Multiply the second equation by 4 both sides
Adds this equation to the first equation system A
----> first equation system B
----> second equation system B
so
The first equation of System B is obtained by adding the first equation of System A to 4 times the second equation of System A
The second equations are identical
therefore
They will have the same solution
Answer:
x=
1/2
and y=3
Step-by-step explanation:
Let's solve your system by substitution.
y=10x−2;2x+y=4
Step: Solvey=10x−2for y:
y=10x−2
Step: Substitute10x−2foryin2x+y=4:
2x+y=4
2x+10x−2=4
12x−2=4(Simplify both sides of the equation)
12x−2+2=4+2(Add 2 to both sides)
12x=6
12x
12
=
6
12
(Divide both sides by 12)
x=
1
2
Step: Substitute

2
forxiny=10x−2:
y=10x−2
y=10(
1
2
)−2
y=3(Simplify both sides of the equation)
Answer:
x=
