change the equation from standard from to slope-intercept from by solving for y
11x - 8y - 48
bob's work:
-8y = -59x
y = 7.375
bill's work:
-8y = -11x - 48
y = 11/8x + 6
Bud's work:
-8y = -11x - 48
y= -11x + 6
who solved y correctly?
A. none of them are correct
B.bill
C.bud
D.bob
The correct answer is C. Bud.
are you sure?
Apologies for the confusion. It seems like there might have been an error in Bud's work.
Let's solve the equation properly to find the correct answer:
Given equation: 11x - 8y = 48
Bob's work:
-8y = -11x + 48
y = (11/8)x - 6
Bill's work:
-8y = -11x + 48
y = (11/8)x - 6
Bud's work:
-8y = -11x + 48
y = (11/8)x - 6
All three answers are the same, so the correct answer is A. None of them are correct.
D. Bob solved for y correctly.
To solve the given equation for y and change it from standard form to slope-intercept form, we need to isolate y on one side of the equation.
Let's analyze each solution:
Bob's work:
Bob divides both sides of the equation by -8, which is correct. However, there is a mistake in his solution. It should be y = (-59/8)x, not y = 7.375. Therefore, Bob's work is incorrect.
Bill's work:
Bill also divides both sides of the equation by -8, which is correct. However, there is another mistake in his solution. It should be y = (-11/8)x - 6, not y = (11/8)x + 6. Therefore, Bill's work is incorrect.
Bud's work:
Bud divides both sides of the equation by -8, which is correct. Additionally, his solution is correctly simplified, and the final equation in slope-intercept form is y = -11x + 6. Therefore, Bud's work is correct.
Based on the analysis above, the correct solution for y in slope-intercept form is given by Bud. Hence, the correct answer is option C. Bud.
