Answer:
Simplify the expression.
7x2+14x−3
Step-by-step explanation:
The required simplification can be given as 7x²+ 14x - 3
What is simplification?
The operation in mathematics to process and interpret the relation to make function simple or more simple is called simplify and the phenomenon is called simplification.
We have,
= (5x² + 8x - 3) + (2x² - 7x + 13x)
= 5x²+ 2x²+ 8x - 7x + 13x - 3
= 7x²+ 14x - 3
Thus, the required simplification can be given as 7x²+ 14x - 3

The cost of a cab ride is $10 for the first mile or part of a mile. It costs $3 for each additional mile or part of a mile and all cab rides are less than six miles. The cost is modeled by the function C(m), where "m" is the number of miles. The driver's pay "P" is a function of the cost "C" and is modeled by P(C) = 0.60C. What is the domain of P(C)?
Answer: {10, 13, 16, 19, 22, 25}
Step-by-step explanation:
Cab ride cost for first mile = $10
Additional mile cost = $3
Therefore, the following cab cost for different miles are analysed:
Cab ride cost for first mile = $10
Cab ride cost for second mile = $10 + $3 = $13
Cab ride cost for third mile = $10 + $3 + $3 = $16
Cab ride cost for fourth mile = $10 + $3 + $3 + $3 = $19
Cab ride cost for fifth mile = $10 + $3 + $3 + $3 + $3 = $22
Cab ride cost for sixth mile = $10 + $3 + $3 + $3 + $3 + $3= $25
Therefore, th domain of P(C) will be equal to {10, 13, 16, 19, 22, 25}
Answer: B) {10, 13, 16, 19, 22, 25}

Factor the following expression completely:
75y-- 5y3 - 10y2 =
Answer:
5 y (y^2 - 2 y + 15)
Step-by-step explanation:
Factor the following:
-(-5) y^3 - 10 y^2 + 75 y
Hint: | Multiply -1 and -5 together.
-(-5) = 5:
5 y^3 - 10 y^2 + 75 y
Hint: | Factor common terms out of 5 y^3 - 10 y^2 + 75 y.
Factor 5 y out of 5 y^3 - 10 y^2 + 75 y:
Answer: 5 y (y^2 - 2 y + 15)
verbally explain how to obtain the graph of the quadratic function f(x)=-2(x+3)^2-4 from the graph of y=x^2.
Answer:
The graph f(x)=[tex]-2(x+3)^2-4[/tex] is a reflection over the x-axis, vertical stretch by a factor of 2, a horizontal translation left 3 units and a vertical translation 4 units down of the graph y=[tex]x^2[/tex].
Step-by-step explanation:
The graph f(x) is reflected over the x-axis because the negative is outside of the parenthesis.
it's a vertical stretch by a factor of 2 because 2 is outside of the parenthesis and is greater than 1.
(x+3) is a horizontal translation left 3 units because it is inside the parenthesis.
-4 is vertical translation 4 units down because it is outside of the parenthesis.

Answer:
B. [tex]\frac{-3}{4}[/tex]±[tex]\frac{\sqrt{41} }{4}[/tex]
Step-by-step explanation:
First, substitute the equation into the quadratic formula.
[tex]x=\frac{b+-\sqrt{(b^{2} )-4(a)(c)} }{2a}[/tex]
x=[tex]\frac{-3+-\sqrt{(3)^2-4(-2)(4)} }{4}[/tex]
Solve for x.
x= [tex]\frac{-3+-\sqrt{9+32} }{4}[/tex]
x=[tex]\frac{-3+-\sqrt{41} }{4}[/tex]
The answer is x= [tex]-\frac{3}{4}[/tex]±[tex]\frac{\sqrt{41} }{4}[/tex]
The Learning Center charges a one-time fee of $26 plus $10 per piano lesson. Guitar lessons have a one-time fee of $36 plus $8 for each lesson. After how many lessons will the cost of learning to play piano be the same or more than learning to play guitar
Given :
The Learning Center charges a one-time fee of $26 plus $10 per piano lesson.
Guitar lessons have a one-time fee of $36 plus $8 for each lesson.
To Find :
After how many lessons will the cost of learning to play piano be the same or more than learning to play guitar.
Solution :
Mathematical expression of piano lesson :
[tex]P_1=26+10x[/tex]
Mathematical expression of guitar lesson :
[tex]P_2=36+8y[/tex]
( Here, x and y are number of lessons )
Let, after t hours cost of learning to play piano be the same or more than learning to play guitar.
Now, given constraint :
[tex]P_1 \geq P_2\\\\26+10t \geq 36+8t\\\\2t \geq 10\\\\t\geq 5[/tex]
Hence, this is the required solution.

(x - 6)(x² + 2x - 4)
Step 2: Distribute each term
x³ + 2x² - 4x
-6x² - 12x + 24
Step 3: Combine
x³ + 2x² - 4x - 6x² - 12x + 24
Step 4: Combine like terms

9) Carla's credit card statement showed that she owed $350. She
Thade a payment of $200, then she charged $23 for gasoline She
returned a sweater she had charged earlier for a refund of $35
Then she charged $15 at the bookstore. What is her new balance?
35
Answer:
the answer is -153
Step-by-step explanation:
350-200(she paid off 200$)=150
150+23(she charged her account 23$)=173
173-35(she paid off 35$)=138
138+15(she charged her account 15$)=135
her new balance is -153$ because that is how much she has left to pay off before she reaches 0 then she can gain credit.

Answer:
Step-by-step explanation:
a number is no more than 26 inequalities
Answer:
n is less than or equal to 26
Step-by-step explanation:
I'm guessing you're asking for the inequality, and since a number (n) cannot be more than 26, it has to be less.
The question never said that n can't be 26, and it only said it can't be MORE than 26, so it's less than or equal to 26, so that's what I'm thinking

12x + k = c solve for x Explain how to do it please
Answer: x=(c-k)/12
Step-by-step explanation:
So you're trying to find x, and in order to do that, you need x by itself. First, move k to the right side by subtracting k from both sides to get 12x=c-k. After that, you divide 12 for both sides to get x=(c-k)/12. It looks like this: [tex]\frac{c-k}{12}[/tex]
What times 4 equals -384
Answer:
-96
Step-by-step explanation:
-384 divided by 4 = -96
hope this helped!!
Answer:
-96
Step-by-step explanation:
If we use the "classic math" and do this like -394/4
we would get -96.
Or we can use a calculator and type -384 / 4 and get the same answer -96 (or unless you did your math incorrect)

What is the property that allows you to solve a polynomial by setting each 5p factor equal to zero? *
Example:
x^2 + 5x + 6 = 0
(x+3)(x+2) = 0 .... factor
x+3 = 0 or x+2 = 0 ... zero product property used here
x = -3 or x = -2 .... solve each equation for x
------
In general, the zero product property is that if A*B = 0, then either A = 0 or B = 0.
how do you solve 2(3-p)-17=41
Answer:
The answer is p = − 26
