find the slope of the line passing through (-4, 5) and (-8,-5)

Answers

[tex](\stackrel{x_1}{-4}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{-8}~,~\stackrel{y_2}{-5}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-5}-\stackrel{y1}{5}}}{\underset{run} {\underset{x_2}{-8}-\underset{x_1}{(-4)}}}\implies \cfrac{-10}{-8+4}\implies \cfrac{-10}{-4}\implies \cfrac{5}{2}[/tex]

Slope = (y2 - y1) / (x2 - x1)

Slope = (-5 - 5) / (-8 - -4)

Slope = -10 / -4

Slope = 10 / 4

The total cost of four pens and six mechanical pencils is $16.20. The cost of each pencil is 70 cents. Using an arithmetic approach, find the cost of a pen.​

Answers

Answer:

300 cents or $3

Step-by-step explanation:

Let p be the cost of one pen and m be the cost of one mechanical pencil. We can use this to set up a system of equations:

4p+6m=1620 (convert $16.20 to cents by multiplying it by 100)

m=70

We can solve this using substitution (substitute 70 for m):

4p+6(70)=1620

4p+420=1620

Subtract 420 from both sides

4p=1200

Divide both sides by 4

p=300 cents or $3

There are 8 boxes of pasta on a shelf. Each serving of pasta is 16 of a box.


How many servings of pasta are there in the boxes on the shelf?

Answers

Answer: 1 1/3 servings of pasta on the shelf.

Step-by-step explanation:

All you need to do is 8*1/6 because if there are 1/6 of a serving of pasta in each box and you have 8 boxes, then you need to multiply to find the number of servings.

8*1/6=1 1/3 or 1.(3)

(3) or any other number in parentheses next to a decimal means it's a repeating decimal, and it never ends.

What is the ratio of a to b if 2a=4c & 6c=5b​

Answers

Answer:

6a:10b

Step-by-step explanation:

Make both C's equal eachother which we could make 12

4x3=12 and 6x2=12

so we will have to do the same for the other numbers so when 4x3=12 then 2x3=6 and then do the same for 5b where 6x2=12 and 5x2=10

this would make the ratio 6a:12c:10b which would then make the ratio 6a:10b

Answers

Answer:

B

Step-by-step explanation:

4x - 3y = 9 → (1)

4x + y = 7 → (2)

Rearranging (1) in terms of x or y will involve using fractions, which we want to avoid if possible.

However, using equation (2) avoids introducing fractions.

In (2) subtract 4x from both sides

y = 7 - 4x → (3)

Then substitute y = 7 - 4x into (1) and proceed

Equivalent expressions are expressions that have equal values

The value of x is 25/6

How to calculate the value of x

From the question, the values of ac and ec are equivalent

So, we have:

8x - 14 = 2x + 11

Collect like terms

8x - 2x = 14 + 11

Evaluate the like terms

6x = 25

Divide both sides by 6

x = 25/6

Hence, the value of x is 25/6
