Answer:
x = 2, y = 4
Step-by-step explanation:
x + 
y = 5 ( multiply through by 4 to clear the fraction )
4x + 3y = 20 → (1)
x - 
y = 0 ( multiply through by 2 to clear the fraction )
2x - y = 0 → (2)
Multiplying (2) by 3 and adding to (1) will eliminate y
6x - 3y = 0 → (3)
Add (1) and (3) term by term to eliminate y
10x + 0 = 20
10x = 20 ( divide both sides by 10 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
4(2) + 3y = 20
8 + 3y = 20 ( subtract 8 from both sides )
3y = 12 ( divide both sides by 3 )
y = 4
Solution is x = 2, y = 4
Answer:
g(x) = 1/3 (x - 12) .. vertical compression with factor 1/3 from f(x-4)
Step-by-step explanation:
*f(x) = x - 8 ... horizontal translation right 8 units from parent function f(x)=x
f(x-4) = (x-4) - 8 = x - 12 .... horizontal translation right 4 units from f(x)=x-8
g(x) = 1/3 (x - 12) .. vertical compression with factor 1/3 from f(x-4)
Answer:
A) 6
Step-by-step explanation:
The angle 12x is the same angle as the one below 108 degrees. They are supplementary angles so they add up to 180 degrees. 180-108 = 72, 12x = 72 divide each side by 12, x = 6 :)
The answer would be B, since the other two just have to equal 100.
Answer:
It should be 90
Step-by-step explanation:
Because 270 divided by 3 is 90
