What is the slope between point A (-9, 4) and B ( 3, -2)

MaRussiya [10]

Slope can be calculated using the formula: m= $\frac{y2 -y1}{x2-x1}$

y1/x1 represents the first number in the bracket

y2/x2 represents the second number in the bracket

Calculation

m = $\frac{y2 -y1}{x2-x1}$

m = $\frac{4 - (-2)}{(-9)-3}$

m= 6/-12

m= -0.5 or -1/2

Therefore, the answer is B.

Help pls

Alenkasestr [34]

Answer:

Jay could be thinking of 11

Step-by-step explanation:

Prime numbers are the numbers that have two factors only, 1 and itself as

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, .................

All prime numbers can divide by 1 and itself only

∵ A number is a prime number

∵ The sum of its digits is 1 more a square number

∴ The sum of its digits = 1 + x, where x is a square number

→ We will start with the first prime number of 2-digits

∵ 11 is a prime number

∵ The sum of its digits = 1 + 1 = 2

→ Substitute it in the equation above to find x

∴ 2 = 1 + x

→ Subtract 1 from both sides

∵ 2 - 1 = 1 - 1 + x

∴ 1 = x

∵ 1 is the square of 1

∴ Jay could be thinking of 11

<em>You can check some of the other prime numbers to find another number</em>

Answer:

Yes, SSS

Step-by-step explanation:

Well they are congruent since well the triangles are from a square which means that the sides will all be equal so therefore it is the SSS rule which stands for "side, side, side" meaning all of the sides are equal.

The cost of a package of ground beef (y) is directly proportional to its weight in ounces (x). A 14-ounce package costs $7. Writ

Sonja [21]

Answer:

$y = \dfrac{1}{2}x$

Step-by-step explanation:

The standard equation of direct variation is

y = kx

where k = constant of variation

We start with

y = kx

Since we are give one ordered pair, we use its coordinates for x and y, and we solve for k. We are told that when x = 14 ounces, y = $7.

7 = k * 14

k = 7/14

k = 1/2

Now that we know k = 1/2, we can write the direct variation equation:

$y = \dfrac{1}{2}x$
