What is the slope of a line parallel to the line whose equation is 5x+y=-9

Answers

Answer:

slope = - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c (m is the slope and c the y- intercept )

Given

5x + y = - 9 ( subtract 5x from both sides )

y = - 5x - 9 ← in slope- intercept form

with slope m = - 5

Parallel lines have equal slopes, thus

The slope of a parallel line to the given equation is m = - 5

Solve for H: A = L ⋅ W ⋅ H
H = A times W over L
H = W times L over A
H = L times A over W
H = A over quantity L times W

Answers

Answer:

The answer would be

H = A over L times W

Step-by-step explanation:

This is because, when you multiply the L, W, and H you end up getting A. This means that A is the biggest number. We automatically can tell that H is what were looking for so putting those two things together we have this: H = A over ???

The ??? would have to be L times W because those are the only things left and they get multiplied together which in the end leaves us with

H = A over L times w

aka

H=A/LxW

Answer:

first and third quadrants

the answer B

Step-by-step explanation:

on the first quadrant x and y are both positive

in the second one x is negative and y positive so -x/y=-1

on the third quadrant x and y are both negative

so -x/-y=1

on the fourth quadrant x is positive and y negative so

x/-y=-1

here, in all cases x and y are taken the same length that's why we take always 1 or -1

Determine if the sequence is arithmetic or geometric, and find the common difference or ratio.


x 1 2 3 4
f(x) 5 −5 −15 −25
Arithmetic, common difference = −10
Arithmetic, common difference = −1
Geometric, common ratio = −10
Geometric, common ratio = −1

Answers

Answer:

The sequence is arithmetic with a common difference of -10

Step-by-step explanation:

From the question, we want to determine if the sequence is arithmetic or geometric

From the question

f(1) = 5

f(2) = -5

f(3) = -15

Mathematically for the common difference;

f(3) - f(2) = f(2) - f(1)

Since;

-15-(-5) = -5-5

-10 = -10

Since the common difference here is same , then the sequence is arithmetic with a common difference of -10

Find the value of x
(9x-38)+(4x+23)=180

Answers

Answer:

x=15

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

9x−38+4x+23=180

9x+−38+4x+23=180

(9x+4x)+(−38+23)=180(Combine Like Terms)

13x+−15=180

13x−15=180

Step 2: Add 15 to both sides.

13x−15+15=180+15

13x=195

Step 3: Divide both sides by 13.

13x/13=195/13

Answer:

15

Step-by-step explanation:

9x-38+4+23=180

13x-15=180

13x=195

x=15

1 pack of cigarettes contains 20 cigarettes. Each cigarette smoked is said to reduce a person's life expectancy by 11 minutes. If a person smoked one pack per day for 25 years, how much shorter would their life possibly be? In minutes: In days: In hours: In years: bruh, heaLP

Answers

Answer:

Step-by-step explanation:

1 pack per days means 20 cigarettes a days each cigarette reduces life by 11  minutes. which is 220mins per day

25*365*24*60 =13140000mins originally

1) 25 years in minutes will be

 reduction of life due to smoking =  220*365*25= 2007500minutes

2)In days

originally = 9125days

after smoking=220/24*60=0.1527*365*25= 1393days are reduced

3)In hours

originally = 219000hrs

reduced life =3.67*365*25= 33488.75hrs

Maria makes $6.00 an hour plus 5% commission for telephone sales. Yesterday, Maria worked 8 hours and had sales of $600.00. How much did Maria make yesterday? Explain your answer.

Answers

Given:

Maria makes $6.00 an hour plus 5% commission for telephone sales.

Working time = 8 hours

Sales = $600.00.

To find:

The amount that Maria make yesterday.

Solution:

We know that,

1 hour = $6.00

8 hour = 8 × $6.00 = $48.00

Commission = 5% of telephone sales

Sales = $600.00.

[tex]Commission=5\times 6[/tex]

[tex]Commission=30[/tex]

Total amount that Maria make yesterday is the sum of total hourly changes plus commission.

[tex]\$48.00+\$30.00=\$78.00[/tex]

Therefore, the required amount is $78.00.

Answer:

a) Angle XBC = 55⁰ because its correspond to Angle AXY which is equal to 55⁰ and corresponding angles are equal.

b)Angle BXC = 70⁰

Step-by-step explanation:

b) Since XB = XC, triangle BXC is therefore an isosceles triangle.

Angle XBC = Angle XCB

Sum of interior angles of a triangle = 180⁰

55⁰ + 55⁰ + Angle BXC = 180⁰

110⁰ + Angle BXC = 180⁰

Angle BXC = 180⁰- 110⁰

= 70⁰
