PLEASE HELP 4. The Buff City Soaps in Arlington is counting how many soaps and bath bombs they sell in a given day. In total, they sold 33 bath products. The number of soaps they sold was one more than three times the number of bath bombs. WRITE THE SYSTEM OF EQUATIONS.​

Answers

Answer:

33 = x + (3x + 1)

x = bath bombs

So 3x is three times as many bath bombs, then the plus one makes it so that the soaps sold is more than three times the amount of bath bombs sold

Find the equation of a line through the coordinate (3,−2) and parallel to the line represented by y=12x−2.

Answers

Answer:

Step-by-step explanation:

y + 2 = 12(x - 3)

y + 2 = 12x - 36

y =12x - 38

The required equation of the line passing through (3, -2) and parallel to the line represented by y = 12x - 2 is y = 12x - 38.

What is Slope?

Slope is usually denoted by m.

Slope is defined as the change in the value of the y coordinates with respect to the change in the value of x coordinates.

Equation of a line in slope intercept form is y = mx + c where m is the slope and c is the y-intercept.

y-intercept is the y coordinate when x coordinate equals zero.

It is given that the required line is parallel to y = 12x - 2.

Comparing with the slope intercept form of the line, the slope of  y = 12x - 2 is 12.

Slope of two parallel lines are equal.

So the slope of the required line = 12

It is also given that required line passes through the point (x, y) = (3, -2).

Substituting these values,

-2 = (12 × 3) + c

-2 = 36 + c

c = -2 - 36

c = -38

So the required equation is found by substituting m = 12 and c = -38.

y = 12x - 38

Hence the equation of the line passing through (3, -2) and parallel to the line y = 12x - 2 is y = 12x - 38.

Casey is making a flower arrangement with roses r and carnations c the cost of each rose is $0.50 and the cost of each carnation is $0.10 . the arrangement has a total $20. how many of each flower did Casey put in his arrangement

Answers

Answer:

r+c=80

.50r+.10c=20

Step-by-step explanation:

each rose costs $0.50

each carnation costs $0.10

The number of roses is r, and the number of carnations is c.

the arrangement has a total of 80 flowers, so we have that:

r + c = 80

the cost is $20, so we have:

r*0.5 + c*0.1 = 20

so our system of equations is:

r + c = 80

r*0.5 + c*0.1 = 20

and we can also solve it; for this isolate one of the variables in the first equation:

r = 80 - c

now let'r replace this in the second equation:

(80 - c)*0.5 +c*0.1 = 20

40  - c*0.4 = 20

c = 20/0.4 = 50

this means that we have 50 carnations, and the other 30 are roses.

for m(x)=-2x+7, find the value of x for which m(x)=13

Answers

Answer:

x = -3

Step-by-step explanation:

m(x) = -2x + 7

13  = -2x + 7

6 = -2x

x = -3

The answer is x= -3




The explanation if you need it is since m(x)=13 we get the equation 13=-2x+7. Then we use the equation to find x.


13= -2x+7
-7 -7
6= -2x
— —
-2 -2

-3=x

You then want to check your answer by substituting -3 for x

13= -2(-3) +7
13= 6+7
13=13

the temperature in an experiment is increased at a constant rate over a period of time until the temperature reaches 0 degrees celsius. the equation y=5/2x-70 gives the temperature y in degrees celsius x hours after the experiment begins. Find and interpret the x- and y- intercepts.

Answers

Answer:

x = 28 (So it takes 28 hours for the temperature to reach 0°C.)

y = -70 (So the temperature when the experiment begins is −70°C.)

Step-by-step explanation:

To find the the x value, you remove the y value or replace it with 0.

0 = 5/2x - 70

Next you move the variable.

70 (2/5) = x           (multiply 70 by 2 to get 140 and divide that by 5)

And now you simplify to get:

28

To find the y value, you remove the x value or replace it with 0.

y =  0 - 70

And now you simplify to get:

-70

x = 28

y = -70

x = 28 (So it takes 28 hours for the temperature to reach 0°C.)

y = -70 (So the temperature when the experiment begins is −70°C.)

Both chemical and physical changes affect the state of matter. Physical changes are those that do not change the make-up or identity of the matter. For example, clay will bend or flatten if squeezed, but it will still be clay. Changing the shape of clay is a physical change, and does not change the matters identity. Chemical changes turn the matter into a new kind of matter with different properties. For example, when paper is burnt, it becomes ash and will never be paper again. The difference between them is that physical changes are temporary or only last for a little while, and chemical changes are permanent, which means they last forever. Physical and chemical changes both affect the state of matter.Passage #2 The Best PB & J EverWhen I got home from school after a long boring day, I took out the peanut butter, jelly, and bread.

Passage #3 Bobby FischerRobert James Fischer was born in Chicago but unlocked the secrets of chess in a Brooklyn apartment right above a candy store. At the age of six he taught himself to play by following the instruction booklet that came with his chess board. After spending much of his childhood in chess clubs, Fischer said that, One day, I just got good. That may be a bit of an understatement. At the age of 13 he won the U.S. Junior Chess Championship, becoming the youngest Junior Champion ever. At the age of 14 he won the U.S. Championship and became the youngest U.S. Champion in history. Fischer would go on to become the World Champion of chess, but he would also grow to become his own worst enemy. Instead of defending the title, he forfeited it to the next challenger without even making a move, and the rise of a chess superstar ended with a fizzle.Passage #4 Save the TigersDr. Miller doesnt want the tigers to vanish.

Our donations will help to support and empower those who are fighting the hardest to preserve the tigers. We owe it to our grandchildren to do something.Passage #5 The Great RecessionMany people are confused about why our economy went to shambles in 2008. The crisis was actually the result of a combination of many complex factors. First, easy credit conditions allowed people who were high-risk or unworthy of credit to borrow, and even people who had no income were eligible for large loans. Second, banks would bundle these toxic loans and sell them as packages on the financial market. Third, large insurance firms backed these packages, misrepresenting these high-risk loans as safe investments. Fourth, because of the ease of acquiring credit and the rapid growth in the housing market, people were buying two or three houses, intending to sell them for more than they paid. All of these factors created bubbles of speculation. These bubbles burst, sending the whole market into a downward spiral, causing employers to lose capital and lay off employees. Consumer spending then plummeted and most businesses suffered. The economy is like a big boat, and once it gets moving quickly in the wrong direction, its hard to turn it around.
