20/ 7
7 goes into 20, 2 times oh whatever the answer is
2 and 6/7
Answer:
x=14
Step-by-step explanation:
create an equation out of it. 4x+2x-6=90. Or 6x=84
Answer:
(-1,2)
Step-by-step explanation:
y = -2x ______(1)
7x - 8y = -23 ________(2)
Substituting the value of y in eqn.(1) into eqn (2);
7x - 8(-2x) = -23
7x + 16x = -23
23x = -23
x = -1
y = -2(-1) = 2.
A polynomial function of least degree with integral coefficients that has the
given zeros 
Given
Given zeros are 3i, -1 and 0
complex zeros occurs in pairs. 3i is one of the zero
-3i is the other zero
So zeros are 3i, -3i, 0 and -1
Now we write the zeros in factor form
If 'a' is a zero then (x-a) is a factor
the factor form of given zeros

Now we multiply it to get the polynomial
