Answer:
no solution
Step-by-step explanation:
2x + 4y = 6......reduces to x + 2y = 3
3x = 12 - 6y....reduces to x = 4 - 2y...rearranged is x + 2y = 4
so now we have :
x + 2y = 3
x + 2y = 4
ok....I dont have to go any farther to know that this has no solution because ur equations have the same slope and different y int, this means ur lines are parallel and have no solution because they never cross each others path.
Answer:
Step-by-step explanation:
EF - base1
HG - base2
J-midpoint of EH
K-midpoint of FG
We are solving it by using formula:
JK=(base1+base2):2
25=(3x+2+7x-2):2
25*2=10x
50=10x
x=50:10
x=5
Good luck!
Answer:
10
Step-by-step explanation:
The ratio of abc/def=1.5
15/1.5=10
if you have insta follow me if you want at riztofu
The coordinates of the midpoint are (-6,3)
Answer:

Step-by-step explanation:
step 1
Find the 
we know that
Applying the trigonometric identity

we have

substitute





Remember that
π≤θ≤3π/2
so
Angle θ belong to the III Quadrant
That means ----> The sin(θ) is negative

step 2
Find the sec(β)
Applying the trigonometric identity

we have

substitute




we know
0≤β≤π/2 ----> II Quadrant
so
sec(β), sin(β) and cos(β) are positive

Remember that

therefore

step 3
Find the sin(β)
we know that

we have


substitute

therefore

step 4
Find sin(θ+β)
we know that

so
In this problem

we have




substitute the given values in the formula
