Distribute first
25-2z-10z=-12z-24-1
combine like terms
25-12z=-12z-25
add 12z to both sides
25=-25
no solution because the right side has a negative
Answer:
Part 1)
Part 2)
Step-by-step explanation:
<u><em>Analize two problems</em></u>
Part 1) If y varies directly with x, and If y=-8 and x= -3 what’s x when y= 6
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
step 1
Find the value of the constant of proportionality k
For x=-3, y=-8
substitute the given values
step 2
Find the linear equation
step 3
Find the value of x when y=6
substitute the value of y in the linear equation
solve for x
simplify
Part 2) If y varies inversely with x, and If y=-8 and x= -3 what’s x when y= 6
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form or
step 1
Find the value of the constant of proportionality k
For x=-3, y=-8
substitute the given values
step 2
Find the equation
step 3
Find the value of x when y=6
substitute the value of y in the equation
solve for x
42 times
first, you do 2 1/3 times 3, which is 7. That means 7 miles in one week. then, you do the number of miles times the number of weeks. So, that is 7x6 which is 42.
The answer is B but make sure u hit the right button
