Answer:

x=7

Step-by-step explanation:

okay so you can see that there is a isocales triangke so that means the other base angle has to be 8x

then you know that the dioganels are perpendicular to each other

so then you know that 8x+5x-1+90=180

13x-1=90

Find the real solution(s) of the following equation. n to the power of 3 =64

Answers

Answer:

n = 4

Step-by-step explanation:

To do this you would find the cube root of 64 which is 4.

n =4 will be the only solution of the following equation. n to the power of 3 =64.

What are mathematical operations?

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given an equation n to the power of 3 =64.

This equation can also be represent as:

n³ = 64

taking cube root of the Both sides

n = ∛64

n = 4

Therefore,  the real solution of the following equation. n to the power of 3 =64 is n = 4.

1 - Find the values of x for which the combined function h(x) = f(x)/g(x) is undefined if f(x) = 5x + 1 and g(x) = x^2 - 9.

x = ±3
x = 3
x = -3
x = ±9

2 - Find the function h(x) = f(x) - g(x) if f(x) = 3^x and g(x) = 3^2x - 3^x.

h( x) = 0
h( x) = -3 ^2x
h( x) = 3 ^x(2 - 3 ^x)
h( x) = 2(3 ^2x)

Answers

Answer:

Part 1)

A

Part 2)

C

Step-by-step explanation:

1)

We are given:

[tex]f(x)=5x+1\text{ and } g(x)=x^2-9[/tex]

And that:

[tex]h(x)=f(x)/g(x)[/tex]

And we want to now for which values of x is h(x) undefined.

So, by substitution:

[tex]\displaystyle h(x)=\frac{5x+1}{x^2-9}[/tex]

Remember that for rational functions, the function will be undefined if and only if the denominator is 0.

This is because we cannot divide by 0.

So, to find the values for which the denominator is 0, set the denominator to 0 and solve for x. Therefore:

[tex]x^2-9=0[/tex]

Add 9 to both sides:

[tex]x^2=9[/tex]

Take the square root of both sides. Since we are taking an even-root, we will need plus/minus. Therefore:

[tex]x=\pm 3[/tex]

So, h(x) is undefined for ±3.

Our answer is A.

2)

We are given:

[tex]f(x)=3^x\text{ and } g(x)=3^{2x}-3^x[/tex]

And we want to find:

[tex]h(x)\text{ if } h(x)=f(x)-g(x)[/tex]

So:

[tex]h(x)=3^x-(3^{2x}-3^x)[/tex]

Distribute:

[tex]h(x)=3^x-3^{2x}+3^x[/tex]

Combine like terms:

[tex]h(x)=2(3^x)-3^{2x}[/tex]

Rewrite:

[tex]h(x)=2(3^x)-(3^x)(3^x)[/tex]

Factor out:

[tex]h(x)=3^x(2-3^x)[/tex]

So, our answer is C.

Step-by-step explanation:

4 Inches on short side, this means that the long side is 8 inches because the short side is always 1/2 the length of the long side, The medium side length is 4√3. So you need to take the short side and medium side and multiply them by 1/2, look below for how to do it.

Answer:

x = 9

-1 + 14x = 12x + 17

Answer:

x = 9

Step-by-step explanation:

-1 + 14x = 12x + 17

Rearrange terms.

14x - 1 = 12x + 17

Add 1 to both sides of the equation.

14x - 1 + 1 = 12x + 17 + 1

Simplify.

14x = 12x + 17 + 1

14x = + 12x + 18

Subtract 12x from both sides of the equation.

14x - 12x = + 12x - 12x + 18

Simplify.

2x = + 12x - 12x + 18

2x = 18

18 ÷ 2 = 9

x = 9

5 + x = 3(x - 7) + 6

Answers

Answer:

x=10

Step-by-step explanation:

x+ 5= 3x - 21 +6

x+5 = 3x - 15

20= 2x

X=10
The reason for this is you distribute the 3 giving you 5+x=3x-21+6.
Then add the 6 to make 5+x=3x-15
Add 15 on both sides to make 20+x=3x
Subtract x on both sides to be 20=2x
Divide both sides by 2 to make 10=x

In a shop, the cost of 4 shirts, 4 pairs of trousers and 2 hats are $560. The cost of 9 shirts, 9 pairs of trousers and 6 hats is $1,290. What is the total cost of 1 shirt, 1 pair of trousers and 1 hat?

Answers

Answer: Given:

4 shirts, 4 pairs of trousers , and 2 hats is $560

9 shirts, 9 pairs of trousers , and 6 hats is $1,290

1) Let x be the price of 1 shirt

Let y be the price of 1 pair of trousers

Let z be the price of 1 hat

2) 4x + 4y + 2z = 560

3) 9x + 9y + 6z = 1,290

4) (9x + 9y + 6z) / 3 = 1,290 / 3

3x + 3y + 2z = 430

5)

4x + 4y + 2z = 560

- (3x + 3y + 2z = 430)

x + y = 130

6) 3(x+y) + 2z = 430

3(130) + 2z = 430

390 + 2z = 430

2z = 430 - 390

2z = 40

z = 40/2

z = 20

7) x = price of 1 shirt; y = price of 1 pair of trousers ; z = price of 1hat

x + y = 130 ; z = 20

130 + 20 = 150

The price of 1 shirt, 1 pair of trousers, and 1 hat is $150.

So this is not impossible!
