Answer:
Step-by-step explanation:
y - 3x = 18
To find the y- intercept let x = 0 in the equation and solve for y
y - 3(0) = 18
y - 0 = 18
y = 18 ⇒ (0,18 ) ← y - intercept
To find the x- intercept let y = 0 in the equation and solve for x
0 - 3x = 18
- 3x = 18 ( divide both sides by - 3 )
x = - 6 ⇒ (- 6, 0 ) ← x- intercept
Answer:
- A. Since 11 ≠ 9, there is no solution
Step-by-step explanation:
<u>Given system:</u>
- 1.75x + 1.25y = 2.75
- 7x + 5y = 9
<u>Multiply the first equation by 4:</u>
- 4(1.75)x + 4(1.25)y = 4(2.75)
- 7x + 5y = 11
We get same equation as the second one with the difference that the right side equals to 11.
Since left sides are same and right sides are different, the system has no solution.
