Answer:
1. y=ax^2+bx+c, where a,b, and c are real numbers and a doesn't equal zero
2. Parabola
3. Opens upward
4. Opens downward
5. Vertex
6. Axis of Symmetry
7. Zeros, roots, or x-intercepts
8. You are already given the function so
Step 1: FInd Axis of Symmetry
Equation for Axis of Symmetry: x= - b/2a
Step 2: Find Vertex
- The vertex will be on the Axis of Symmetry, so plug in x then find y.
Equation for Vertex: Ex. The vertex is (-5) which is x now we find y by plugging in -5 whenever we see an X. f(x) = -(-5)^2 - 10(-5)-25=0 our vertex would be (-5,0)
Step 3: Draw your coordinates plane and "dash in" the axis of symmetry. Then plot your vertex
Step 4: Plot your y-intercept and the point symmetrical to it. The y-intercept is "c"
Step 5: Find at least other point on the parabola and draw the curve.

How many gallons each of 0.5% milk and 3% milk should a dairy farmer combine to
get 7 gallons of 2% milk?
Answers
Answer:
2.8 gallons 0.5% milk
4.2 gallons 3% milk
Step-by-step explanation:
let 'x' = .5% milk
let 'y' = 3% milk
System of Equations:
x + y = 7
.005x + .03y = 7(.02)
I used the substitution method and solved the first equation for y: y = 7 - x
.005x + .03(7 - x) = .14
.005x + 0.21 - .03x = 0.14
-0.025x + 0.21 = 0.14
-0.025x = -0.07
x = 2.8
7 - 2.8 = 4.2
y = 4.2

The school band is selling t-shirts for a fundraiser. The initial cost for a steamer to apply the decals is $100. It is predicted that the cost of material for each shirt is $12. The function that shows the band's average cost per t-shirt after x t-shirts are sold is:
Answers
Answer: Vertical asymptotes is x = 0 and the horizontal asymptotes is y = 12.
The average cost approaches to 12 when the number of shirts increases.
Step-by-step explanation:
Since we have given that
Initial cost for a steamer to apply the declas = $100
Cost of material for each shirt = $12
Function representing the band's average cost per t-shirt after x t-shirt are sold is given by:
We need to find the vertical asymptotes , horizontal asymptotes and the average cost to make a t-shirt approaches as the number of t-shirts increases,
For vertical asymptotes , we will make denominator equal to zero.
So, it will be
Thus, vertical asymptotes is x= 0.
Similarly,
For horizontal asymptotes, we first check the degree of both numerator and denominator.
Since we can see that both have the same degree i.e. 1.
So,
So, the horizontal asymptotes is y = 12.
When the number of shirts increases ,The average cost to make a T-shirt approaches is given by
Hence, the average cost approaches to 12 when the number of shirts increases.
Answer:
The vertical asymptote is x = 0
The horizontal asymptote is y = 12
The average cost to make a t-shirt approaches $12 as the number of t-shirts made increases.
Step-by-step explanation:
Angela's aunt is two more than three times her age. The total of their ages is 54. How old is Angela and how old is her aunt?
Answers
Answer:
Angela is 13 years old and Angela's aunt is 41 years old.
Step-by-step explanation:
With the information provided you know that Angela's aunt is two more than three times her age, which could be expressed as:
x=3y+2, where:
x is Angela's aunt age
y is Angela's age
Also, you know that the total of their ages is 54, which is:
x+y=54
Now, you can replace x=3y+2 in x+y=54 and solve for y:
3y+2+y=54
4y=54-2
4y=52
y=52/4
y=13
Finally, you can replace the value of y in x=3y+2 to find x:
x=3(13)+2
x=39+2
x=41
According to this, the answer is that Angela is 13 years old and Angela's aunt is 41 years old.

Answer:
x = 9
Step-by-step explanation:
Corresponding sides are in proportion. That means that [tex]\frac{x - 1}{6} = \frac{16}{12}[/tex]
12x - 12 = 96
12x = 108
x = 9
By the way, the scale factor is 16/12 = 4/3
The value of x of a polygon is :
x= 9.
