ax4 + bx2 + c=0 (a>0) (c>0)
The quadratic equation has two solutions If
1)b2>4ac
2) b2-4ac>0
The quadratic equation has two solutions if b^2 - 4ac > 0
Given the equation ax^4 + bx^2 + c=0
Let P = x^2Substitute into the formula to have:
a(x^2)^2 + bx^2 + c =0The equation becomes aP^2 + bP + c = 0
For us to have a unique solution, the discriminant b^2 - 4ac must be greater than zero. Hence the quadratic equation has two solutions if b^2 - 4ac > 0

Number 3 is 10
Step-by-step explanation:
16+13(10)=146
14(10)+6=146
Answer:
See answer below.
Step-by-step explanation:
# 3 x = number of boxes
$16 + 13x = Tracy cost
$6 + 14x = Brendan cost
The costs are equal.
16 + 13x = 6 + 14x
10 + 13x = 14x
10 = x

14x + 23y = 222 multiply by -21 ⇔ -294x - 483y = -4662
258x = 1548
x = 6
Six people at each tables
24 (6) + 21y = 270
144 + 21y = 270

Function: y=x^2−4x−12
Factored Form: y=(x+_) (x-_)
x -Intercepts: (_,_) and (_,_) Type answers smallest to largest left to right.
Axis of Symmetry: x=
Vertex:
Domain:
Range: y≥
Answer:
Below in bold.
Step-by-step explanation:
y=x^2−4x−12
Factored form: y = (x - 6)(x + 2)
x-intercepts: (-2, 0) and (6, 0).
Axis of symmetry is found by converting to vertex form:
y = x^2−4x−12
y = (x - 2)^2 - 4 - 12
y = (x - 2)^2 - 16.
So axis of symmetry is x = 2.
Vertex is at (2, -16)
Domain is all Real Numbers.
Range is y ≥ -16.

Hello, Can you please take a look at this screenshot I have below, This problem is confusing :/
Answer:
See answers below.
Step-by-step explanation:
m ∠A + m ∠B + m ∠C = 180° The sum of the angles in a triangle = 180
28° + x - 4 + 2x = 180° Substitution
x = 52° Algebra
28° + x - 4 + 2x = 180°
24° + 3x = 180°
3x = 156°
x = 156/3
x = 52°
Check: 28° + 48 + 104° = 180√

if you run 4 1/2 miles in three quarter of an hour, how many miles would you run in two thirds
Answer:4
Step-by-step explanation: each quarter of an hour is 1.5 miles they both can go into 12 so if you multiply 2*4 and 3*4 you get 8/12 and if you multiply 3*3 and 4*3 you get 9/12 then you subtract 9/12 by 8/12 to get so 1/12=1/2 miles so you would subtract 4 1/2 by 1/2 to get 4

a local factory has to add a liquid ingredient to make there product at a rate of 13 quarts every 5 minutes. how many gallons per hour of the ingredient do they need to add
Per hour, they would need to add 147 quarts of the liquid ingredient. When converting to gallons, every 4 quarts is one gallon, so we need to divide 147 by 4.
36.75 Gallons Per Hour
They need to add 39 gallons of ingredients to make the production they desire.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
We know 4 quarts are one gallon.
∴ They would be making (13/4) = 3.35 gallons every 5 minutes Or (3.25/5) = 0.65 gallons per minute.
∴ In an hour or 60 minutes, they would be making (0.65×6) = 39 gallons per hour.

An administrative assistant works from home and originally charged her clients $8.75 per hour for any clerical work plus a set fee of $15, or C(h) = 8.75h + 15. She decided to double her hourly fee but keeps her set fee the same. Which of the following functions represents the new fees, N(h)?
Answer:
N(h) = 17.5h + 15
Step-by-step explanation:
N(h) = 8.75h + 15 | write original equation
N(h) = 8.75(2) + 15 | multiply the original hourly fee by 2
N(h) = 17.5 + 15 | solve
Stay healthy and happy <3.
Hope this helped.
The required function represents the new fees is given as N(h) = 17.5h + 15.
Given that,
An administrative assistant works from home and originally charged her clients $8.75 per hour for any clerical work plus a set fee of $15, or C(h) = 8.75h + 15. She decided to double her hourly fee but keeps her set fee the same.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given function,
C(h) = 8.75h + 15.
Now,
According to the question,
N(h) = 2× 8.75h + 15.
N(h) = 17.5h + 15.
Thus, the required function represents the new fees is given as N(h) = 17.5h + 15.
