Answer:
C
Step-by-step explanation:
A closed circle means inclusive, and -2 is included in values that would make the equation true. Then you just have to test another number greater than and less than -2 to see which way the arrow should point.
-3(-3) + 1 < 7
9 + 1 < 7
10 < 7 FALSE
-3(0) + 1 < 7
1 < 7 TRUE
All values (including -2) will make this equation true
Answer:
11.16 units²
Step-by-step explanation:
Area of community area=4.5×6.2= 27.9 units²
Area of vegetable garden=27.9×0.4=11.16 units²
Answer: 3r + 2b = 24
r + 3b = 16
Step-by-step explanation:
Let the red blocks be represented by r
Let blue blocks be represented by b
Since 3 red blocks and 2 blue blocks weigh 24 ounces. This will be:
3r + 2b = 24
1 red block and 3 blue blocks weigh 16 ounces. This will be:
r + 3b = 16
Therefore, the equation will be:
3r + 2b = 24
r + 3b = 16
Answer:
BC = 2
Step-by-step explanation:
We first need to use triangle BAD to find BD,
BD is the hypotenuse, so use pythagorean theorem...
(√23)² + (√13)² = (BD)²
23 + 13 = (BD)²
36 = (BD)²
6 = BD
Now BD is the hypotenuse of triangle BCD, so use pythagorean theorem agian to find BC
(4√2)² + (BC)² = 6²
32 + (BC)² = 36
(BC)² = 4
BC = 2
