f(x)= (x+9x2- 9x +15

Answer:

b = 48 °, c = 46°

Step-by-step explanation:

c = 46 ° as between parallel lines, alternate opposite angles are equal.

since opposite angles are equal 94 ° = 46 ° + additional angel

therefore b = 94° - 46 ° = 48 ° , as sum of 2 internal angles of a triangle is equal to opposite exterior angle.

Answer:

8+ 1/2 (12) = x

8+ 6 = x

Answer:

The answer is X = 14

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

Step 2: Flip the equation.

Answer: The solution set of the system of inequalities is the region above the dashed line (y=-2x-2) and below the solid line (y=x+4).

Answer: 5 people

Step-by-step explanation:

For this word problem, we can use the description in the problem to construct an equation. Let's use x for number of people.

3.5x+5.5x+6=51         [combine like terms]

9x+6=51                      [subtract both sides by 6]

9x=45                         [divide both sides by 9]

x=5

There were 5 people that went to the fair.

Answer:

5 1/4

Step-by-step explanation:

Subtracting a negative is the same as adding a positive.

2 3/8 - (-2 7/8) =

= 2 3/8 + 2 7/8

= 4 10/8

= 4 + 8/8 + 2/8

= 4 + 1 + 1/4

= 5 1/4

Answer:

Step-by-step explanation:

5,762 - (-8)

The total difference between the highest point and the lowest point of the country is given as 5, 770 feet.

Given that,
At its highest point, the elevation of a country is 5,762 feet above sea level. At its lowest point, the elevation of the country is 8 feet below sea level.

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,
Highest point = 5,762
The lowest point below the sea level = -8 feet
Total difference in the point = 5762 - (-8) = 5770 feet

Thus, the total difference between the highest point and the lowest point of the country is given as 5, 770 feet.

Answer:

The value of angle P is 119 degrees

Step-by-step explanation:

When two angles are supplementary, it means that they add up to be 180 degrees. For example, if we have two angles only on a straight line, then both angles are supplementary angles.

Now, the information we have from the question is that angle P is three less than twice the measure of Q.

What this mean is that if Q is x, then P is 2x-3

So let’s add both to equal 180 since they are supplementary;

x + 2x -3 = 180

3x -3 = 180

3x = 180 + 3

3x = 183

x = 183/3

x = 61

This is the value of Q;

The value of P which we are asked to look for is 2x -3 = 2(61) -3 = 122 -3 = 119 degrees

Step-by-step explanation:

Parameters:

As square has all equal sides in  his shape.

then length and width will be equal.

parameters will be

LENGTH,LENGTH,WIDTH,WIDTH

Area:

area of square is known as A= a^2

a= parameter of square (as all parameters are equal,you put one parameter to find area of square)

The required perimeter of the square is 4 times side and the area of the square is ( side ) ².

Given that,
To determine the perimeter and the area of the square.

A square is defined as it is a four-sided polygon, having angles of 90° on its vertices, and the length of all four sides is equal.

Perimeter is the measure of the figure on its circumference or it is overall boundary length of the figures.

Here,
The perimeter of the square is given as the sum of all sides,
= side + side + side + side
= 4 x side

The area of the square is multiplied of two adjacent side
= side x side
= ( side )²

Thus, the required perimeter of the square is 4 times side and the area of the square is (side)².

Answer:

B

Step-by-step explanation:

So we have the two functions:

[tex]f(x)=-2x^2-5x+1\text{ and } h(x)=3(x+3)^2-11[/tex]

And we want to find:

[tex]h(f(-1))[/tex]

So, find f(-1) first. Substitute -1 into f(x):

[tex]f(-1)=-2(-1)^2-5(-1)+1[/tex]

Square:

[tex]f(-1)=-2(1)-5(-1)+1[/tex]

Multiply:

[tex]f(-1)=-2+5+1[/tex]

Add:

[tex]f(-1)=4[/tex]

Now, substitute this into h(f(-1)):

[tex]h(f(-1))=h(4)[/tex]

So, substitute 4 into h(x):

[tex]h(4)=3(4+3)^2-11[/tex]

Add:

[tex]h(4)=3(7)^2-11[/tex]

Square:

[tex]h(4)=3(49)-11[/tex]

Multiply:

[tex]h(4)=147-11[/tex]

Subtract:

[tex]h(4)=136[/tex]

So, our answer is B.

Step-by-step explanation:

Shawn's living room is a square, so all four sides are the same length.  Area of a square is A = s², and we know the area is 196 ft².  If substitute this for A:

196 ft² = s²

Take square root of both sides:

s = √(196 ft²)

s = ±14 ft

Since measurements of lengths can't be negative, s must be +14 ft.  So Shawn's living room is 14 ft x 14 ft.

Answer:

14 ft x 14 ft.

Answer:

x < -2

Step-by-step explanation:

1. Original Inequality: 10 – 2(2x + 2) > 14

2. 10-4x-4>14

Distribute the -2 to 2x and 2.

3. Simplify the left side: 6-4x>14

Do 10-4

4. Subtract: -4x>8

Subtract 6 from both sides to get x by itself

5. Divide: x< -[tex]\frac{8}{4}[/tex]

You want to divide by -4 that way you can find what x is. When you divide OR multiply by a negative number in an inequality you are going to need to switch the way the sign is facing.

6. Simplify: x< -2

7. Check:

10-2(2(-3) +2) > 14

10-2(-6 + 2)

10-2(-4)

10+8

18 > 14

Hello! :)

−4x + 6 > 14 Simplify both sides

−4x + 6 − 6 >1 4 − 6 Subtract 6 from both sides

−4x > 8

-4x/-4 > 8/-4 Divide both sides by -4

x < -2 (ANSWER)
