Answer:

A.

C.

Step-by-step explanation:

A. When adding a negative number to a positive, you subtract. 2.3 - 2.3 will equal 0.

B. When adding two negative numbers, you get an even smaller negative number. (-3.7) + (-4.1) = -7.8

C. When subtracting a negative number, the two negative signs become a positive. -12/4 is equal to 3. -2.6 + 3 is 0.4, which is positive.

D. 5/2 is the same as 2.5. If you subtract 2.5 from 2.5, you will get 0, which is not negative.

E. Two negative signs make a positive, so 72 + 100 is positive, not negative.

What is the slope of the line that passes through the points (7,26) and (12, -39)?​
Elena-2011 [213]
The slope (m) = -13.

We can use the slope formula:

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

Let (x1, y1) = (7, 26)
(x2, y2) = (12, -39)

Plug in the values into the formula:

m = (y2 - y1) / (x2 - x1)
m = (-39 - 26) / (12 - 7)

m = -65/5

m = -13

Y=x+5 y = x + 5 Find four points contained in the inverse. Express your values as an integer or simplified fraction.
Karolina [17]

Answer: (0,-5), (5, 0), (10, 5) and (15,10).

Step-by-step explanation:

Given equation: y = x + 5

To find its inverse we will find the value of x .

Subtract 5 from both sides

x=y-5

Switch y to x, we get

y= x-5, which is the inverse function.

At x=0,

y=-5

At x= 5,

y=0

At x= 10 ,

y=5

At x= 15,

y= 10

Hence, the four points contained in the inverse: (0,-5), (5, 0), (10, 5) and (15,10).

PSYCHO15rus [73]

Ralph (r): a + 5

Alphonse (a): a

Ralph + Alphonse = Total

(a + 5) + (a) = 73

2a + 5 = 73

2a = 68

a = 34

Ralph: a + 5 = 34 + 5 = 39

Answer: Ralph has 39 marbles, Alphonse has 34 marbles
