the answer is x=−1 and y=1
Step-by-step explanation:
hoped I helped:)
the answer is b
X is a bigger number and the difference between x and y is 7, so x-y=7. And it says that the sum of two numbers is 31 so x+y=31
159.2 or 159 1/5 If you need it as a fraction
Answer:
b, since the others have the input and output on the wrong sides
Answer:
f(x)=5x^3-2x^2-90x-36=0
=x^2(5x-2)-18(5x-2)=(x^2-18)(5x-2)=0
x^2-18=0/5x-2=0
x^2=18=x=9√2
5x-2=0
x=2/5
zeros are 9√2,2/5
