Find the missing coefficient. -___________ y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0
Answers
Answer:
Missing Coefficient is -8
Step-by-step explanation:
We are given, _y² - [ -5y - y( -7y -9) ] - [ -y(15y + 4) ] = 0
We have to find missing value.
let missing value be a
ay² - [ -5y - y( -7y - 9) ] - [ -y(15y + 4) ] = 0
ay² - [ -5y + 7y² + 9y ] - [ -15y² - 4y ] = 0
ay² - [ 7y² + 4y ] + 15y² + 4y = 0
ay² - 7y² - 4y + 15y² + 4y = 0
ay² - 7y² + 15y² + 4y - 4y = 0
( a - 7 + 15 )y² = 0
RHS can be written as
( a - 7 + 15 )y² = 0.y²
Now comparing coefficient of both sides we get,
a - 7 + 15 = 0
a + 8 = 0
a = -8
Therefore, Missing Coefficient is -8
Hope this helps! (:

Answer:
C. ++ ++ ++ ++
Step-by-step explanation:
Note that the numbers are positive 4 & positive 2 (which explains the + signs).
The answer can be two ways. 4 groups of 2, or 2 groups of 4.
C. ++ ++ ++ ++ is your answer, for it is 4 groups of 2. Note that A is not the answer, for that would be for adding, in which you have one group of 4 and one group of 2.

3 divided by 0.05 is equal to 60.
Given that we need to find the value of 3 divided by 0.05,
To calculate 3 divided by 0.05, you can use the following formula:
3 ÷ 0.05 =
To divide by a decimal number like 0.05, you can multiply both the numerator and denominator by a power of 10 to eliminate the decimal point.
In this case, multiplying by 100 will work:
Now we can perform the division:
Simplifying further:
Finally, performing the division:
300 / 5 = 60
Therefore, 3 divided by 0.05 is equal to 60.
