Step-by-step explanation:
-3+6k+11k-10-9y+5x-y-13x
-13+17k-10y-8x
-5x+6x-9x+5xy
-8x+5xy
3x^2 - 7x + 12 = 0 ....subtract 12 from both sides
3x^2 - 7x = -12 ....divide both sides by 3 to get x^2 by itself
x^2 - 7/3x = -4
His work is not accurate because he divided the second term by 4 instead of 3.
Your answer is gonna be 98. multiply all of the numbers
Answer:
y=5 when x=20
Step-by-step explanation:
Using the format for inverse proportions: y=k/x
To find k, substitute 25 in for y and 4 for x to find:
25=k/4 ⇒ k=100
Using this we can substitute k and x in for 100 and 20 to find:
y=100/20 ⇒ y=5
Answer:
choice 2, y=1/4x
