Answer:
6x+15
Step-by-step explanation:
3x - 4y = 18 ⇒ 3x - 4y = 18
2x + y = 1 ⇒ 8x + 4y = 4
11x = 22
11 11
x = 2
2x + y = 1
2(2) + y = 1
4 + y = 1
- 4 - 4
y = -3
(x, y) = (2, 3)
Convert the fraction to a decimal by dividing the numerator by the denominator to approximate the decimal result.
Answer=0.6666666666666
Answer:
1) a
2) b
3) a
Step-by-step explanation:
The student is wrong in not putting a parenthesis between 1/3 and x. An equation of a line has a general equation of y = mx + b where m is the slope and b is the y-intercept. In this case, most likely 1/3 is the slope and 0 is the y-intercept. However, writing the equation like that seems like the x variable is a denominator and if that is the case the equation will not represent a line already.
