Answer:

x = 13

Step-by-step explanation:

Step 1: Define

f(x) = (x - 1)/2

f(x) = 6

Step 2: Substitute and solve for x

6 = (x - 1)/2

12 = x - 1

x = 13

Answer:

108.8 yd²

Step-by-step explanation:

The area (A) of the triangle can be calculated as

A = [tex]\frac{1}{2}[/tex] absinC

where a, b are 2 sides and C the angle between them

Here a = 23, b = 9.5 and C = 85° , thus

A = 0.5 × 23 × 9.5 × sin85° ≈ 108.8 yd² ( to the nearest tenth )

Answer:

Terms: 7, 8p, -27

Coefficients: 8

Step-by-step explanation:

1. A term is a constant, a variable, or a product of a constant and variable. Therefore, 7, 8p, and -27 are terms.

2. A coefficient is a number that is in front of a variable like 8 in front of p.

Answer:

60

Step-by-step explanation:

The angle measures in a triangle always add up 180 degrees. 180-80-40=60

X-6y<-12 in slope intercept form is y > 1/6X + 2

Length of Wire = 176 cm

It's bent into a square.

Side of square = 176/4 = 44 cm

Area of square = Side × Side = 44 × 44 = 1,936 sq.cm

Then it's bent into a circle.

Circumference of the circle = 2πr = 176 cm

Circumference = r = 176/2 × 7/22 = 28 cm

Area of circle = πr^2

Area = 22/7 × 28 × 28

Area = 2,464 sq.cm

The Circle will have more area than the square.

Answer: 0

Step-by-step explanation:

No matter how you go at it, x is inevtably going to equal 0. To get x by itself, you have to subtract 3 from the right and left side, which leaves 0=x-5x. That leaves you with -4x=0, and when divided, that equals zero.

Answer:

x = 0

Step-by-step explanation:

Given

3 = x + 3 - 5x , that is

3 = - 4x + 3 ( subtract 3 from both sides )

0 = - 4x , thus

x = 0

Answer:2, -2, 6 or -6

Step-by-step explanation:

Given,

The location of Ann's house in the number line = 0,

∵ Ben lives 4 blocks from Ann.

So, the possible location of Ben's house =  4 ( right of ann's house ) or - 4 ( left of ann's house )

Now, Carl lives 2 blocks from Ben,

So, the possible location of Carl's house

Case 1 : If Ben's house location is 4 = 2 ( left of ben's house ) or 6 ( right of ben's house )

Case 2 : If Ben's house location is -4 = -2 ( right of ben's house ) or -6 ( left of ben's house )

Answer:

ok but thx for the points

Step-by-step explanation:

The remainder when the polynomial x² + 3x + 7 is divided by x + 2 is 5.

A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.

The remainder theorem states that for a polynomial, f(x) divided by a linear polynomial , x - a, the remainder is equal to f(a).

Given the polynomial; f(x) = x² + 3x + 7, since it is divided by x + 2, hence:

x + 2 = 0

x = -2

f(-2) = (-2)² + 3(-2) + 7 = 5

Hence the remainder when the polynomial x² + 3x + 7 is divided by x + 2 is 5.

Answer:

Option A

Step-by-step explanation:

If the length is twice as long as the width (14 ft), that makes it 28 ft. (14 x 2=28)

14 ft x 28 ft = 392 square feet

Therefore, the area of the solar cover is [tex]392[/tex] square feet. i.e., option (A) is the correct answer.

What is the simplification?

Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

Here given that,

Mrs. King is buying a solar cover for her rectangular swimming pool. The cover will float on the surface of the pool and has the same dimensions as the pool.

The pool is twice as long as it is wide. Its width is 14 feet.

If the length is twice as long as the width [tex]14ft[/tex], that makes it [tex]28 ft[/tex].

Then the [tex](14 (2)=28)[/tex].

So,

[tex]14[/tex] ft x [tex]28[/tex] ft = [tex]392[/tex] square feet

Hence, the area of the solar cover is [tex]392[/tex] square feet. i.e., option (A) is the correct answer.

The midpoint of a line segment means a point that lies in the mid of the given line segment. The coordinates of point B are (7, -4).

Midpoint, as the word suggests, means the point which lies in the middle of something. The midpoint of a line segment means a point that lies in the mid of the given line segment. Suppose we've two endpoints of a line segment:

A(p,q), and B(m,n)

Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:

[tex]x = \dfrac{p+m}{2}[/tex]

and

[tex]y = \dfrac{q+n}{2}[/tex]

Given that the midpoint of AB is M whose coordinates can be written as,

The x-coordinate of point B,

[tex]x_m = \dfrac{(x_A + x_B)}{2}[/tex]

[tex]5 = \dfrac{(3 + x_B)}{2}[/tex]

10 = 3 + x

x = 10 - 3

x = 7

The y-coordinate of point B,

[tex]y_m = \dfrac{(y_A + y_B)}{2}[/tex]

[tex]1 = \dfrac{(6 + y_B)}{2}[/tex]

2 = 6 + y

y = 2 - 6

y = -4

Hence, the coordinates of point B are (7, -4).

Hey there! I'm happy to help!

To solve by substitution, rearrange one of the equations for one of the variables.

3x+2y=11

Subtract 2y from both sides.

3x=11-2y

Divide both sides by 3.

x=11/3-2/3y

Now we plug this value of x into the second equation to solve for y.

2(11/3-2/3y)-2y=14

We use distributive property to undo the parentheses.

22/3-4/3y-2y=14

We combine like terms.

22/3-10/3y=14

We subtract 22/3 from both sides.

-10/3y=20/3

Divide both sides by -10/3.

y=-2

We plug this value into one of the equations to solve for x.

3x+2(-2)=11

3x-4=11

Add 4 to both sides.

3x=15

Divide both sides by 3.

x=5

So, the solution is x=5 and y=-2 or (5,-2).

Answer:

C

Step-by-step explanation:

First, notice that this is a cubic function.

The standard form for a cubic function is:

[tex]f(x)=a(x-b)^3+c[/tex]

Where a is the vertical stretch, b is the horizontal shift, and c is the vertical shift.

From our graph, we can see that unlike the parent function, x³, this cubic is 3 units to the right and 1 unit up from the standard position.

Therefore, our b is +3 and c is +1. Let's substitute these values. Also, let's assume a is 1. So:

[tex]f(x)=(x-3)^3+1[/tex]

Therefore, our answer is C.

And we're done!
