What is the slope represented in the table ?

Natasha_Volkova [10]

Answer:

slope:2

Step-by-step explanation:

Slope is rise/run, or change in y/change in x.

With that being said, we only need two points to solve this.

Let's take the points (0,7) and (1,9)

The formula for finding the slope from two points is m=(y2-y1)/(x2-x1).

M is the slope.

y2 would be the y-value of the second point,9. y1 would be the y-value of the first point, 7.

x2 would be the x-value of the second point, 1. x1 would be the x-value of the first point, 0.

Plugging those values in to the formula, we get m=(9-7)/(1-0)

Simplifying, we get m=2/1, which is m=2.

An experienced cashier at a grocery store takes 2 seconds to scan each item and 40 seconds to process the customer's payment. 1)

Liono4ka [1.6K]

The right answer is Option D: 43 items

Step-by-step explanation:

Time taken to scan each item = 2 seconds

Time taken to process the payment = 40 seconds

Let,

x be the number of items bought

y be the total time

y = 2x+40 Eqn 1

Now

Total time = 2 minutes and 6 seconds

1 minute = 60 seconds

2 minutes = 2*60 = 120 seconds

Total time = 120+6 = 126 seconds

Putting y=126 in Eqn 1

$126=2x+40\\126-40=2x\\86=2x\\2x=86$

Dividing both sides by 2

$\frac{2x}{2}=\frac{86}{2}\\x=43$

43 items are being purchased.

The right answer is Option D: 43 items

What is the sum of 2 3/4 and −2 3/4 ?

makvit [3.9K]

Answer:

2 $\frac{3}{4}$ + -2 $\frac{3}{4}$ = 0

Step-by-step explanation:

1st step convert into improper fraction:

===> 2 $\frac{3}{4}$ + -2 $\frac{3}{4}$

===> $\frac{16}{4}$ + $-\frac{16}{4}$

2nd step now adding the numbers:

( Plus sign and minus sign multiplies and hence the plus sign changes to minus)

===> $\frac{16-16}{4}$

Therefore the sum of 2 $\frac{3}{4}$ + -2 $\frac{3}{4}$ = 0
