Drag and drop numbers into the equation to complete the equation of the line in slope-intercept form.

lara31 [8.8K]

Answer:

y = 4x - 15

Step-by-step explanation:

Find slope (m) using of the line that passes through (7, 13) and (4, 1).

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 13}{4 - 7} = \frac{-12}{-3} = 4$

Find y-intercept (b) by substituting x = 4, y = 1, and m = 4 in y = mx + b.

Thus:

1 = (4)(4) + b

1 = 16 + b

Subtract 16 from each side

-15 = b

b = -15

substitute m = 4, and b = -15 in y = mx + b, to get the equation.

The equation of the line would be:

✅ y = 4x + (-15)

y = 4x - 15

How many cubes with the side length of 1/2 unit do you need to form a three unit cube

jeka57 [31]

Answer:

216 cubes.

Step-by-step explanation:

The easiest way to take on this problem is to divide the side of the bigger cube by the smaller one.

$3 \div \frac{1}{2} = 3 \times 2 = 6$

Then, as in with volume, we cube this value to find the number of cubes necessary to fill such a space.

${6}^{3} = 216$

The numbers of home runs that Barry Bonds hit in the first 18 years of his major league baseball career are listed below. Find t

vekshin1

Answer:

Mean = 35.56

Median = 35.5

Step-by-step explanation:

Given the data:

16 25 24 19 33 25 34 46 37

33 42 40 37 34 49 73 46 45

Reordered data :

16, 19, 24, 25, 25, 33, 33, 34, 34, 37, 37, 40, 42, 45, 46, 46, 49, 73

The mean = ΣX / n

n = sample size ; ΣX = sum of values

The mean = 658 / 18

The mean = 36.56

The Median = 1/2(n+1)th term

1/2(18+1)th term = 1/2(19)th term = 9.5 term

Median = (9th + 10th) / 2 = (34 + 37) / 2 = 35.5

The sum of two numbers is 65 and the difference is 13.what are the numbers?

Karolina [17]

Answer: 26 and 39

Step-by-step explanation:

Let the numbers be x and y . Also , let us take x as the larger number.

From the first statement :

x + y = 65 ...................... equation 1

From the second statement :

x - y = 13 ....................... equation 2

Solving the system of linear equation by elimination method. Let us eliminate y first , then we need to add the two equations to eliminate y , the equation then becomes

2x = 78

x =39

substitute x = 39 into equation 1 , that is

39 + y = 65

y = 65 - 39

y = 26

Therefore , the numbers are 26 and 39
