Answer:
Y= 7.9 lb
X= 10.1 lb
Step-by-step explanation:
The chef orders 2.2 lb more carrots than celery. The two orders weigh 10.8 lb combined.
Let carrot= x
Let celery= y
X+y = 18...... equation one
X= 2.2 +y.... equation two
Substituting the value of x into equation one
2.2 +y +y =18
2y= 18-2.2
2y= 15.8
Y= 7.9 lb
Substituting the value of yinto equation 2
X= 2.2 +y
X= 2.2 + 7.9
X= 10.1 lb
Answer: We can see that it has a parabola for its graph, so we can say that f(x) is a quadratic function. This means that f(x) has a parent function of y = x2.

Answer:
x= -1, -9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/4x2+5/2x+21/4=3
Step 2: Subtract 3 from both sides.
1/4x2+5/2x+21/4−3=3−3
1/4x2+5/2x+9/4=0
For this equation: a=0.25, b=2.5, c=2.25
0.25x2+2.5x+2.25=0
Step 3: Use quadratic formula with a=0.25, b=2.5, c=2.25.
x=−b±√b2−4ac/2a
x=−(2.5)±√(2.5)2−4(0.25)(2.25)/2(0.25)
x=−2.5±√4/0.5
x=−1,−9
