Answer:
The answer is B, 6x^2 - 21x + 15
Step-by-step explanation:
= (3x + − 3) (2x + − 5)
= (3x) (2x) + (3x) (− 5) + ( − 3) (2x) + ( − 3) ( − 5)
= 6x^2 − 15x − 6x + 15
= 6x^2 − 21x + 15

Chau and Yoko each opened a savings account today. Chau opened his account with a starting amount of $460, and he is going to put in $60 per month. Yoko opened her account with a starting amount of $530, and she is going to put in $50 per month.
Let x be the number of months after today.
(a) For each account, write an expression for the amount of money in the account after x months.
Amount of money in Chau's account (In dollars) =
Amount of money in Yoko's account (in dollars) =
(b) Write an equation to show when the two accounts would have the same amount of money.
Answers
Answer:
A1-60x+460
A2-50x+530
B-60x7+460
50x7+530
Step-by-step explanation:
A1 and A2-since x is equivalent to number of months we multiply the number of months then add it to the original cost to get how much total you get in the account.
B-you add 50 to 530 and 60 to 460 until they equal the same amount in this case its 7 times.

6x + 2(7x – 4) = 92 I T
Answers
Answer:
x = 5
Step-by-step explanation:
6x + 2(7x – 4) = 92
simplify:
6x + 14x - 8 = 92
20x = 100
x = 5
Answer:
6x+2(7x−4)=92
Step 1: Simplify both sides of the equation.
6x+2(7x−4)=92
6x+(2)(7x)+(2)(−4)=92(Distribute)
6x+14x+−8=92
(6x+14x)+(−8)=92(Combine Like Terms)
20x+−8=92
20x−8=92
Step 2: Add 8 to both sides.
20x−8+8=92+8
20x=100
Step 3: Divide both sides by 20.
100

To find:
The measure of CP.
Solution:
In triangles ABP and CBP,
[tex]\angle PAB\cong \angle PCB[/tex] (Given right angles)
[tex]\angle ABP\cong \angle CBP[/tex] (Given)
[tex]BP=BP[/tex] (Common side)
Now,
[tex]\Delta ABP\cong \Delta CBP[/tex] (By AAS property of congruence)
We know that the corresponding parts of congruent triangles are congruent.

Angles a and b are ertical angles the measure of angle a is 8x+1 and angle b is 21-2x find each angle measure
Answers
Answer:
Angle a = 17°
Angle b = 17°
Step-by-step explanation:
Angles a and b are vertical angles the measure of angle a is 8x+1 and angle b is 21-2x find each angle measure
Vertical angles are angles that are equal to each other
Step 1
We find x
a = b
Hence,
8x+1 = 21-2x
Collect like terms
8x + 2x = 21 - 1
10x = 20
x = 20/10
x = 2
Step 2
We find each angle
Angle a
8x+1
x = 2
Angle a = 8(2) + 1
= 17°
Angle b
21-2x
x = 2
21 - (2 × 2)
= 21 - 4
= 17°
Therefore:
Angle a = 17°
Angle b = 17°

Suppose a car gas tank holds 21 gallons of gas. On a trip it uses 2/3 of a tank of gas on a trip. Then it uses 1/3 of what is left in the tank. How many gallons of gas are left in the tank? If u can could u show the work?
Answers
9514 1404 393
Answer:
2/9 tank
Step-by-step explanation:
After the first trip, 1 -2/3 = 1/3 of the tank remains.
After the second trip, 1 -1/3 = 2/3 of that remains.
After both trips, (1/3 tank)(2/3) = 2/9 tank remains.

Let the function f(x) have the form f(x) = Acos(x-C). To produce a graph that matches the one shown below, what must the value of C be?
Answers
Answer: Option B, C = 3.
Step-by-step explanation:
Here we have the function:
f(x) = A*cos(x - C)
A is the amplitude, and we can easily see that the amplitude is 2.
Then:
f(x) = 2*cos(x - C)
We also can see that when x = 0, f(x) ≈ -2
This means that:
cos(0 - C) ≈ -1
Cos(C) ≈ -1
Now we can just evaluate in the different options and see which one is the correct option.
Cos(1) = 0.54
Cos(2) = -0.42
Cos(3) = -0.99
Cos(4) = -0.65
The closer option to -1 is when C = 3, then the correct option is option B.

B

Answers
Answer:
Number of terms.
A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.
A binomial has two terms. For example: 5x2 -4x
A trinomial has three terms. For example: 3y2+5y-2
Any polynomial with four or more terms is just called a polynomial. For example: 2y5+ 7y3- 5y2+9y-2
Practice classifying these polynomials by the number of terms:
1. 5y
2. 3x2-3x+1
3. 5y-10
4. 8xy
5. 3x4+x2-5x+9
Answers: 1) Monomial 2) Trinomial 3) Binomial 4) Monomial 5) Polynomial
2. Degree. The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).
