2x+3y=12 and y=x+1.5 in substitution form
1 answer:
Answer:
(1.5, 3)
Step-by-step explanation:
Given the 2 equations
2x + 3y = 12 → (1)
y = x + 1.5 → (2)
Substitute y = x + 1. 5 into (1)
2x + 3(x + 1.5) = 12 ← distribute and simplify left side
2x + 3x + 4.5 = 12
5x + 4.5 = 12 ( subtract 4.5 from both sides )
5x = 7.5 ( divide both sides by 5 )
x = 1.5
Substitute x = 1.5 into (2) for corresponding value of y
y = 1.5 + 1.5 = 3
Solution is (1.5, 3)

Answer: (0,-10) and the transformation should be a reflection
Step-by-step explanation:
$12.6 -- 25% of 12.6 is exactly $3.15
I did this by taking 3.15 / 0.25
11 3/8 would be the simplified version and 91/8 would be the other way.
Answer:
It's line C.
Step-by-step explanation:
the slope of line C is 1/2 so that's the constant of proportionality
No. Because a irrational number has a repeating pattern.
