How many solutions does the system have? {y=−2x+2y=x2−3x Enter your answer in the box.
1 answer:
ANSWER
The system has two solutions.
EXPLANATION
The given equations are
and
We equate both equations to obtain;
This implies that,
where a=1, b=-1,c=-2.
We find the discriminant, D=b²-4ac of this equation to be;
Since the discriminant is greater than zero, it means the two functions intersected at two distinct points.
Hence the system has two solutions.

Answer:
Cherry Pink has not been made ()
Step-by-step explanation:
Given that she already has 60litres of Rose Pink paint, we use the ratios to determine the volumes of red/white used:
#Add these proportions to the additional red and white paints to determine if Cherry Pink has been made:
We equate this proportion to the Cherry Pink proportion to verify if Cherry pink has been made:
Hence, Cherry pink has not been made.
Answer:
we can do it by simplifying 8 to to make both powers base two, and subtracting the exponents.
Step-by-step explanation:
We have been given the expression
8 can be rewritten as
Hence, the given expression becomes
After subtracting the exponents on left hand side of the equation we get:
we can do it by simplifying 8 to to make both powers base two, and subtracting the exponents.
