Answer:
7/2 and 3
Step-by-step explanation:
using quadratic formula
{-(-13) +- √(-13)^2 - 4(2)(21) } /2(2)
-(-13)+1 / 4 = 7/2
-(-13)-1 / 4 = 3
Answer:
The coefficient of variable term y is -1
Step-by-step explanation:
We have an expression given in the question that is:
6 - y + 3
We have to find the coefficient of the variable term.
In mathematics, variable can be defined as any term which is to be measured. For example in the given expression, y is the variable because its value is unknown yet and it has to be measured.
Coefficients are the number the multiply the variable
For example
In 2x, x is the variable and 2 is the coefficient.
Now in the given expression, we have
6 - y + 3
or
6 + (-1)(y) + 3
So considering (-1)(y), the variable is y while its coefficent is -1
Answer:
100
Step-by-step explanation:
25% of 100=25
100+25=125
125-25=100
It goes up 25% then it gets discounted back down to its original price
