4 0

Answer:

  (1, 4)

Step-by-step explanation:

It can work well to try the solutions to see which works:

  • (1, 4) -- 4 > 1/2·1 +2 . . . true
  • (-1, 1) -- 1 > 1/2(-1) +2 . . . false; 1 < 3/2
  • (2, 3) -- 3 > 1/2·2 +2 . . . false; a number is not greater than itself
  • (0, 2) -- 2 > 1/2·0 +2 . . . false; a number is not greater than itself

Carla is saving money for a trip. She already has some money in her savings account and will add the same amount to her account
Bingel [31]

Answer:

280=8x + 130

Step-by-step explanation:

Im pretty sure this is correct it has been a while since I did this but y is the total amount so y is 280. M is the slope so it would be how often the amount changes so m is 8. x is unknown and what needs to be solved for. b is the y intercept which is just the initial amount of 130.

A bowl has the shape of a hemisphere whose diameter is 14 centimeters. If this bowl is filled with water, how many cubic centime
ASHA 777 [7]

Answer:

The cubic centimeters of water it will take to fill the bowl is 718.67 cm³

Step-by-step explanation:

Given;

diameter of the hemisphere, d = 14 cm

radius of the hemisphere, r = d/2 = 14/2  = 7 cm

The volume of the hemisphere is calculated as;

V = \frac{2}{3} \pi r^3\\\\V = \frac{2}{3} \times \frac{22}{7}   \times (7 \ cm)^3\\\\V = 718.67 \ cm^3

The cubic centimeters of water it will take to fill the bowl is 718.67 cm³

The sum of two numbers is 10. twice the first number is 4 more than twice the second. what are the two numbers?
Ludmilka [50]
X+ y = 10
2x = 2y+4

2x/2 = 2/2y+4/2
x = y + 2

x+y = 10
y+2+y=10
2y + 2 = 10
2y +2-2 =10-2
2y = 8
2y/2 =8/2
y = 4

x + y =10
x + 4 =10
x +4-4 =10-4
x = 6

Check
2x = 2y +4
2(6) = 2(4) +4
12 = 8+4
12= 12
