  A.  opens downward; vertex (3, 11)

Step-by-step explanation:

The leading coefficient is negative (-1), so we know the parabola opens downward.

The vertex in the form ...

  A(x) = a(x -h)² +k

is (h, k). Comparing to the given equation, we find (h, k) = (3, 11).

The vertex is (3, 11).

Answer:x=8 or x=-2

Step-by-step explanation:

log4(x-6) + log4(x)=2

log4(x(x-6))=2

4^2=x(x-6)

4x4=x(x-6)

16=x^2-6x

Arrange the quadratic equation

x^2-6x-16=0

x^2+2x-8x-16=0

x(x+2)-8(x+2)=0

(x-8)(x+2)=0

x-8=0. x+2=0

x=8. x=-2

Answer:

A

Step-by-step explanation:

Correct systems of linear equations which represent the two lines are,

a. x=3, y=6

e. y= x + 3, y= 2x

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

There are two lines are graphed on the same coordinate plane.

And, the lines only intersect at the point (3,6).

Now, We know that;

When Point (3, 6) is lies on line then it satisfy the equation of lines.

Hence, By options;

a. x=3, y=6

Clearly, Point (3, 6) is lies on line.

e. y= x + 3, y= 2x

y = x + 3

y = 3 + 3

y = 6

Hence, Point (3, 6) is lies on line.

Thus, Correct systems of linear equations which represent the two lines are,

a. x=3, y=6

e. y= x + 3, y= 2x

Answer and Step-by-step explanation:

We want to verify that (1 + cos(2θ)) / 2cos(θ) = cos(θ).

Let's focus on the left side. Look at cos(2θ). This is an identity, so remember that cos(2θ) = cos²θ - sin²θ. Also, look at the 1. Remember that sin²θ + cos²θ = 1, so plug both of these expressions into our equation:

(1 + cos(2θ)) / 2cos(θ) =? cos(θ)

((sin²θ + cos²θ) + (cos²θ - sin²θ)) / 2cos(θ) =? cos(θ)

2cos²θ / 2cosθ =? cosθ

cosθ = cosθ

Thus, we have proved this is an identity.

Answer:

(1 + cos(2theta))/2cos(theta)

cos(2theta) = 2cos²(theta) - 1

(1 + 2cos²(theta) - 1)/2cos(thetal

2cos²(theta)/2cos(theta)

cos(theta)

Answer: (2y+3)(3x+y-1)

Step-by-step explanation:

First regroup the terms.

6xy+9x+2y^2+y-3

Second factor 3x out of 6xy+9x

3x(2y)+9x+2y^2+y-3

3x(2y)+3x(3)+2y^2+y-3

And you get

3x(2y+3)+2y^2+y-3

Third factor by grouping

Answer:

Step-by-step explanation:

Incase the figure is not clear

here, it is

⇒ 30 = 15 + 20 + 9 - 12 - 6 - 5 + 3 + h

⇒ h = 30 - 44 - 3 + 23

⇒ h = 53 - 47

h = 6

Hence, Totally 6 people hate potatoes

Answer: 6 students hate potatoes.

Step-by-step explanation:

The Venn diagram representing the situation is shown in the attached photo.

Set M represents the set of students that like mashed potatoes.

Set F represents the set of students that like French fried potatoes.

Set T represents the set of students that like Twice-baked potatoes.

H represents the number of students that hate potatoes.

3 liked all three styles

The number of students that like mashed and twice baked potatoes only is 6 - 3 = 3

The number of students that like mashed and French fried potatoes only is 12 - 3 = 9

The number of students that like twice baked and French fried potatoes only is 5 - 3 = 2

The number of students that like mashed potatoes only is 15 - (9 + 3 + 3) = 0

The number of students that like French fried potatoes only is 20 - (9 + 3 + 2) = 6

The number of students that like twice baked potatoes only is 9 - (3 + 3 + 2) = 1

Since the total number of students is 30, it means that

0 + 6 + 1 + 3 + 9 + 2 + 3 + H = 30

24 + H = 30

H = 30 - 24

H = 6

Answer:

a market's condition

Step-by-step explanation:

edge 2021

Market conditions best determine whether a borrower’s interest rate on an adjustable rate loan goes up or down.

It is the cost of borrowing money.

Interest rate levels depend on the supply and demand of the money.

Supply and demand are a part of market conditions.

We see that,

An increase in demand for money will increase the interest rate.

A decrease in demand for money will decrease the interest rate.

Conversely,

An increase in the supply of money will decrease the interest rate.

A decrease in the supply of money will increase the interest rate.

Demand and supply are market conditions

Thus market conditions best determine whether a borrower’s interest rate on an adjustable rate loan goes up or down.

Answer:

Confederate

Step-by-step explanation:

During the time that led up to the conflict known as the Civil War of America, the major cause of tension was slavery. Southern plantation owners and farmers fiercely advocated slavery because they helped with the harvest of crops and the overall southern economy. The northerners, however, resisted slavery, saying it was immorally and inhumanely wrong.

At the culmination of this tension, many southern states, led by Jefferson Davis (who later became the "president" of the Confederate states), decided to secede from the Union (break away) and establish their own entity, which they called the "Confederate States of America".

The unknown angle = 126°

Step-by-step explanation:

From angles in a triangle.

The total sum of angles in a triangle = 180°

Let the unknown angle be x
