  slope = -1/2

Step-by-step explanation:

For the rise of -1 and the run of 2, the slope is ...

  m = rise/run = -1/2 . . . . slope in simplest form

Additional comments

It usually works best if you can identify points on the graph where the line crosses grid intersections. Then the number of squares in each direction can be counted easily. If you work with two grid intersections that are closest together, then the ratio of rise to run will already be in reduced form.

On this graph, there are other grid crossing points that are 4, 6, 8 units to the right or left of the one where we started. You need to remember that "run" is positive in the "right" direction, and "rise" is positive in the "up" direction.

We have shown the "rise" and "run" lines above the graphed line. They can also be shown below the graphed line.

Here, the grid squares are 1 unit in each direction. You need to pay attention to the scale, because some graphs have different numbering vertically than horizontally. The values for "rise" and "run" need to be figured using the appropriate scale.

Answer:

c

Step-by-step explanation:

I just did it on A.P.E.X.

Answer:

A==−x+3y=9

Step 1: Add -3y to both sides.

−x+3y+−3y=9+−3y

−x=−3y+9

Step 2: Divide both sides by -1.

−x

−1

=

−3y+9

−1

x=3y−9

Answer:

x=3y−9

Answer:

  No

Step-by-step explanation:

If all 30 coins were nickels and dimes, there would be 10 dimes and 20 nickels, for a total value of $2.00. Trading a dime and 2 nickels for an equal number of quarters raises the value to $2.00 -0.10 -2(0.05) +3(0.25) = $2.55.

That is, each such trade adds $0.55 in value to the total amount. Since the original difference of $3.00 -$2.00 = $1.00 is not evenly divisible by $0.55, there cannot be twice as many nickels as dimes.

__

For 30 coins, possible numbers of {nickels, dimes, quarters} are ...

{21,2,7}, {18,6,6}, {15,10,5}, {12,14,4}, {9,18,3}, {6,22,2}, {3,26,1}, {30 dimes}

Note that we can have 1.5, 3, or 10.5 times as many nickels as dimes, but not 2 times as many.

Step-by-step explanation:

I had this question on khan academy

have a good day and stay safe!

The value of expression at x = 3 is,

⇒ 30

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 6² + x - x²

Now, We can simplify as;

⇒ 6² + x - x²

⇒ 36 + x - x²

Put x = 3;

⇒ 36 + 3 - 3²

⇒ 36 + 3 - 9

⇒ 36 - 6

⇒ 30

Thus, The value of expression at x = 3 is,

⇒ 30

Answer:

what is the question

Step-by-step explanation:

Answer:

3x+4y=18 and 5x+2y=16

x=the cost of the sodas

y=the cost of the iced teas

then you do

3x+4y=18, and 10x+4y=32 (the equation is still equivalent to 5x+2y=16, you just doubled it)

next,

10x+4y=32

-3x-4y=-18 (once the y's match, make one negative and one positive)

which leaves you with:

7x=14

which means

x=2

Plug the x value back into the equation, for this I chose to plug it back into 3x+4y=18

3(2)+4y=18

6+4y=18

4y=12

y=3

so the final answer is x=2, and y=3

Answer:

slope = 12/7

Step-by-step explanation:

y2 - y1 / x2 - x1 = slope

slope = 4-(-8)/0-(-7)

slope = 12/7

Answer:

According to an advertisement for Colgate toothpaste, 4 out of 20 Dentist prefer Colgate. There are 150 Dentist in a certain city.

Let the number of dentists prefer Colgate in the city be x

[tex] \frac{4}{20} = \frac{x}{150} \\ x = \frac{4 \times 150}{20} \\ \boxed{x = 30}[/tex]

Answer:

There are 45 pepperoni on 3 large pizzas

Step-by-step explanation:

Here, we want to use proportional relationship to solve this;

75 pepperoni to 5 large pizzas

x pepperoni to 3 large pizzas

75 * 3 = x * 5

x = (75 * 3)/5

x = 15 * 3 = 45

Answer:

Equation: y=$3(x)+$30

Total cost $42

Step-by-step explanation:

Calculation to Find the total cost of 4 hours at the aquarium using this formula

y=mx+b

Where,

y intercept=Total cost

m=$3 per hour

b=$30 Tickets

x=4 hours

Let plug in the formula

First step is to form the equation

y=$3(x)+$30

Second step is to substitute 4 hours for m and b

y=$3(4)+$30

Hence:

y=$12+$30

y=$42

Therefore the equation will be y=$3(x)+$30 while the total cost of 4 hours at the aquarium will be $42

Answer: twenty one decreased by eighteen or the difference of twenty one and eighteen

Answer:

y = 3/8 x - 2

Step-by-step explanation:

Put 8y on the other side to get

8y + 16 = 3x

8y = 3x - 16 and thus

y = 3/8 x - 2

Answer:

35.79 minus 3 b

Step-by-step explanation:

Mariah purchases three hair barrettes by using a gift card, which starts with a balance of $35.79.

Let the number of barrettes be represented by b

She purchases 3 barrettes

Hence = 3 × b = 3b

Hence, the expression that models her purchase is given as:

$35.79 - 3b

Answer:

35.79-3b

Step-by-step explanation:

The value of the gift card 35.75 minus the cost of 3 barrettes (3b).

so 3b stands for 3 barrettes.

The simplest form of 42/18 is 7/3 or 2 1/3

Step-by-step explanation:

Answer:

7/3 or 2 and 1/3

Step-by-step explanation:

So first you have to find what is GCF of 42 and 18, which is 6 so divide 42 and 18 by 6 and you get 7/3 which is your simplified fraction but you can make this into a mixed number which would be 2 and 1/3

Answer: Hi, sorry if I’m late to answering but the answer is 19

Step-by-step explanation:

You divide each number in the equation by 5. So, 5x divided by 5 = 1. We cannot use 5 divided by 5 because it will equal 1 so we ignore that and go to 95 divided by 5 = 19. Therefore, 19 is your answer!!! (Hope this helped)

Answer: 6.5%

Step-by-step explanation:

In 6 years the interest earned is:

= 2,780 - 2,000

= $780

The account earns simple interest which means that it increased by the same rate yearly. Yearly increase is:

= 780/6

= $130

Simple interest rate = Interest payment/ Deposit

= 130/2,000

= 6.5%
