20 points for first person to answer

Mathematics
1 answer:
lys-0071 [83]2 years ago
8 0

Answer:

3, 4 and 5

Step-by-step explanation:

The total number of marbles Janae, Jerome and Gwen have is m + m + 4(m + 2).

m + m + 4(m + 2)

= 2m + 4m + 8

= 6m + 8

The problem says that the total number of marbles Janae, Jerome and Gwen have is less than the number of marbles John has, so that means 6m + 8 is less than 8m + 4

6m + 8 < 8m + 4.

(6m + 8) - 4 < (8m + 4) - 4

6m + 4 < 8m

4 < 8m - 6m

4 < 2m

1 and 2 aren't valid so the answer is 3, 4 and 5.

The given table values represents a liner equation. What is the slope?
Arada [10]

Answer:

A. 2

Step-by-step explanation:

slope (m) = \frac{y_2 - y_1}{x_2 - x_1}

Use any two points given in the table of values. Let's use (1, 5), (3, 9)

Let,

(1, 5) = (x_1, y_1)

(3, 9) = (x_2, y_2)

Plug these values into the slope formula:

slope (m) = \frac{9 - 5}{3 - 1}

slope (m) = \frac{4}{2}

slope (m) = 2

Which point does not lie on the circle centered at (3, 2) with radius 5? A) (0, 6) B) (3, -3) C) (-2, 2) D) (3, 0)
vladimir1956 [14]

Answer:

D

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (3, 2) and r = 5, hence

(x - 3)² + (y - 2)² = 25 ← equation of circle

If an ordered pair lies on the circle then it satisfies the equation, if not then it does not lie on the circle.

Substitute the coordinates of the points into the left side of the equation of the circle and check validity.

A

(0 , 6) : (0 - 3)² + (6 - 2)² = 9 + 16 = 25 ← lies on circle

B

(3, - 3) : (3 - 3)² + (- 3 - 2)² = 0 + 25 = 25 ← lies on circle

C

(- 2, 2) : (- 2 - 3)² + (2 - 2)² = 25 + 0 = 25 ← lies on circle

D

(3, 0) : (3 - 3)² + (0 - 2)² = 0 + 4 = 4 ≠ 25 ← not on circle
