Answer:
3
Step-by-step explanation:
Since 4/25 = 1/4 that means ?/12 = 1/4 so in this case it would be 3 since 12 is divided by 3 to get to 4 for the denominator.
Answer:
x = 4.5 AND x = -4
Step-by-step explanation:
for the first answer
add 9 to 0 and divide by 2
for the second answer
subtract 4
Answer:
9
Step-by-step explanation:
jerry-3 = molly
molly = 6
jerry - 3 = 6
jerry = 9
Answer:
Option B 3,-3,-6 is correct.
Step-by-step explanation:
We need to find real zeroes of
Solving
Taking x^2 common from first 2 terms and -9 from last two terms we get
Taking (x+6) common
x^2-9 can be solved using formula a^2-b^2 = (a+b)(a-b)
Putting it equal to zero,
So, Option B 3,-3,-6 is correct.
ANSWER
EXPLANATION
The given line passes through the origin, hence it has equation of the form,
Therefore y varies directly as x.
The line passes through the point (3,1)
This implies that,
Hence the constant of variation is
The equation is
