What is Algebra?

A branch of mathematics known as **algebra** deals with **symbols** and the mathematical **operations **performed on them.

Variables are the name given to these symbols because they lack set values.

In order to **determine **the **values**, these **symbols **are also **subjected **to various addition, subtraction, multiplication, and division arithmetic **operations**.

Given:

let p the number of **pennies**, d be the number of **dimes**, n be the number of **nickels **and q be number of **quarters**.

So, the **expressions **are

p = 3d

n = d+1

= 5(d+1)

d = 10d

and, q = 2d

= 25 (2d)

and, the **total **is = $209

= 209

Then,

3d + 5(d+ 1) + 10d +25 ( 2d) = 209

68d + 5 = 209

d = 3

Thus, the **number** of **quarters **= 2d = 6 quarters.

(x^2+3x^2-kx-24)÷(x+3) what's the value of k??

### Answers

**Answer:**

-4

**Step-by-step explanation:**

since x+3 is a factor of the polynomial (x^2+3x^2-kx-24), then;

x+3 = 0

x = -3

Substitute x = -3 into the polynomial

x^2+3x^2-kx-24 = 0

(-3)^2+3(-3)^2-(-3)k-24 = 0

9 + 27 + 3k - 24 = 0

36-24 + 3k = 0

12 = -3k

k = -12/3

k = -4

**Hence the value of k is -4**

A room has a perimeter of 40 feet. The length is 4 less than 2 times the width. What are the dimensions of the room?

### Answers

**Answer:**

First, develop an equation for this scenario. The formula to find the perimeter of a quadrilateral is 2l+2w. Because the length is 4 less than twice the width, this would be translated to (2w-4). Plug this into the variable for the length to get 2(2w-4)+2w=40. Distribute the 2 to get 4w-8+2w=40. Add the like terms to get 6w-8=40. Add 8 to both sides and get 6w=48. Divide 6 to result with w=8.

Now that we know w, we can substitute 8 into the variable to solve for the length. 2l+2(8)=40. Multiply 8 and 2 to get 2l+16=40. Subtract 16 to both sides to get 2l=24. Divide 2 to both sides to result with l=12.

Length = 12 feet

Width = 8 feet

Does the point (6, 0) satisfy the equation y = x + 6?

yes or no

### Answers

**Answer:**

No.

**Step-by-step explanation:**

You have to replace the (6,0) with the equation at hand. So, since 6 is in the X spot and 0 is in the Y spot, the equation would then look like 0=6+6. The equation is false as you can see.

**No**, this point does **not lie** on the line **y = x + 6**.

What is the general equation of a Straight line?

The **general equation** of a straight line is -

**y = mx + c****[m]** → is **slope **of line which tells the** unit rate** of change of [y] with respect to [x].**[c]** → is the **y - intercept** i.e. the point where the graph cuts the [y] axis.

Other **possible equations **of lines are -

**(y - y₁) = m(x - x₁) ** {Point - slope form}**(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) ** {Two point - slope form}**x/a + y/b = 1 ** {intercept form}**x cos(β) + y sin(β) = L ** {Normal form}

We have the **equation **of line as -

**y = x + 6**

For point (6, 0), we can write -

0 = 6 + 6

**0 ≠ 12**

Therefore, **no**, this point does **not lie** on the line -

**y = x + 6**

the sum of two numbers is 84 and one of them is 12 more than the other what are the two numbers

### Answers

The first number is x

The second number is y

So according to the given condition the sum of these two numbers is 84, so we can write

x+y=84 ————-(1)

Again one of them is more than 12 than the other that's why we can write,

x+12=y -------------(2)

Now putting the values of y in equation (1) we get,

x+x+12=84

=>2x+12=84

=>2x+12–12=84–12

=>2x=72

=>2x/2=72/2

=>x=36

Taking the value of x in equation(2) we get,

36+12=y

=>y=48

The two numbers are 48 and 36.

Check:

48+36=84

=>84=84

Also 48 =36+12; which is more than 12 of 36.

The angle of elevation from the

standing to the top of the pole

is 62°. Find the height of the

telephone pole. Round to

the nearest tenth.

### Answers

**Answer:**

Approximately 15.05 ft

**Step-by-step explanation:**

You need to use tangent for this question.

Since tan θ = [tex]\frac{Opposite}{Adjacent}[/tex]

to find the Opposite, we need to rearrange the equation to:

Adjacent × tan θ = Opposite.

So if you insert 62 for θ and 8 feet for Adjacent, you will get:

8 × tan(62) = Opposite.

and you will get approximately 15.05 feet for your Opposite side
