What is the slope of a line that is perpendicular to the line y = 1?

O-1

ОО

O 1

O undefined

**Answer: D) Undefined**

Explanation:

The equation y = 1 is the same as y = 0x+1

Match that to the form y = mx+b to see that the slope is m = 0

Any horizontal line has a slope of 0.

Notice that we cannot apply the negative reciprocal to this because 0 = 0/1 leads to 1/0 which is **undefined**

The slope of any vertical line is **undefined **because we have run = 0 and slope = rise/run = 1/0. The rise can be any number you want (it doesn't have to be 1) and we get the same result.

The **slope** of a line that is **perpendicular** to the line y = 1 is undefined.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the **steepness** of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the **y intercept.**

The slope of line passing through two **points** (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The **equation** y = 1 is the same as y = 0x+1

Match that to the form y = mx+b to see that the slope is m = 0

Any horizontal line has a **slope** of 0.

y = 1 is an vertical line.

The slope of any** vertical line** is undefined because we have run = 0 and slope = rise/run = 1/0.

= Undefined

Hence, the **slope** of a line that is **perpendicular** to the line y = 1 is undefined.

**Answer:**

Before the increase it was $136.416.

**Step-by-step explanation:**

16% of $162.40 is 25.984.

We need to do $162.40 - 25.984 which equals to $136.416.

In a company,55% of the workers are men. If 2,250 people work for the company who aren't men, how many. Workers are there in all?

**Step-by-step explanation:**

female workers:2250

% female workers:?

First, find the percentage of workers who aren't men since we are told the number of workers who aren't men

100-55=45

Therefore 45% of workers aren't men

Let the total number of workers =x

Now form an equation for the problem

[tex]x \times \frac{45}{100} = 2250[/tex]

[tex]x = 2250 \div \frac{45}{100} [/tex]

[tex]x = 5000[/tex]

Therefore, there are 5000 workers in total

The line 2x + 3y = 8 meets the curve 2x^2 + 3y^2 =110 at the points A and B. Find the coordinates of A and B.

extra: This is the first time I’ve seen this type of question without a diagram. Pls help!

**Answer:The cordinates of A and B are (-3.8, 5.2) and (7, -2).**

**Step-by-step explanation:From (1), we get x = (8 - 3y) / 2 ––(3)
**

**
**

**Substitute (3) into (2),
**

**
**

**2 [(8 - 3y) / 2]² + 3y² = 110
**

**
**

**(8 - 3y)² + 3y² = 220
**

**
**

**15y² - 48y - 156 = 0
**

**
**

**Therefore y = 5.2, then x = (8 - 3×5.2) / 2 = -3.8
**

**
**

**OR y = -2, then x = [8 - 3×(-2)] / 2 = 7
**

**
**

**Answer:**

The coordinates are** A. (-3.8, 5.2) and B. (7, -2).**

**Step-by-step explanation:**

At A and B the coordinates satisfy both equations so we solve simultaneously using substitution:

2x^2 + 3y^2 = 110

2x + 3y = 8

From the above equation

x = (8 - 3y)/2

So substituting for x in the first equation:

2 [(8-3y)/2]^2 + 3y^2 = 110

(8-3y)^2 / 2 + 3y^2 = 110

Multiply through by 2:

(8 - 3y)^2 + 6y^2 = 220

64 + 9y^2 - 48y + 6y^2 - 220 = 0

15y^2 - 48y - 156 = 0

3(5y^2 - 16y - 52) = 0

(5y - 26)(y + 2) = 0

y = 26/5, 2

**y = 5.2, -2.**

So substituting in 2x + 3y = 8

When** y = -2:**

2x - 6 = 8

2x = 14

**x = 7.**

When** y = 5.2**

2x + 3(5.2) = 8

2x = 8 - 15.6 = -7.6

**x = -3.8.**

PLEASE HELP GIVING 50 POINTS!!

**Answer:**

y = 18

**Step-by-step explanation:**

Direct variation means y will change by the same factor x does. When x changes by a factor of 15/10 = 1.5, the value of y will change by that same factor

x = 10, y = 12

x= 15, y = 1.5×12 = 18

**The new value of y is y = 18**.

_____

Written as a proportion, you have ...

y/15 = 12/10

y = 15×12/10 = 18

__

Written as a direct variation equation, you have ...

y = kx

12 = k·10 ⇒ k = 1.2

y = 1.2·15 = 18 . . . . for x=15

**Answer: A. 20%**

**Step-by-step explanation:**

First, to find the total number of teachers, we can add 25+32+18+5+20=100

Next, we divide the number of teachers in 2014 (20) by the total number of teachers (100) as follows:

20 ÷ 100 = 0.2

Finally, to make 0.2 a percentage, we can multiply 0.2 X 100 = 20

Therefore, the correct answer is A.

Answer:

It represents 3x20 +3x15

Step-by-step explanation:

The expression 3(20+15) represents 20+15 then multiplying it by three.

If you were to solve the expression, the answer would be 105.

20 + 15 = 35

35 x 3 OR 35(3) OR 35 ∙ 3 = 105

17+15+b = 180 so If you do 180-(15+17) =b

Well we know 15+17 is 32 so now you do 180-32 which equals 148 so b=148

Well we know 15+17 is 32 so now you do 180-32 which equals 148 so b=148
