Y > -x + 4
Because your variable cannot be negative
These two angles are supplementary, meaning that there sum is 180 degrees. To solve this make a formula:
97 + x = 180
Subtract 97 to both sides to isolate x
97 - 97 + x = 180 - 97
x = 83

Answer:
12 = 5 + x
Step-by-step explanation:
Total fish in the aquarium = 12
Number of guppies fish = 5
Number of other fishes = x
Total fish in the aquarium = Number of guppies fish + Number of other fishes
12 = 5 + x
Subtract 5 from both sides
12 - 5 = 5 + x - 5
7 = x
x = 7
Number of other fishes = x = 7
Answer:
(x + 2)²(x - 3)² = 0
Step-by-step explanation:
Since we have a degree of 2 and double of the same roots, we know that each root would have a multiplicity of 2. Therefore, our answer is(x + 2)²(x - 3)² = 0
Answer:
27.76 grams will be present in 500 years
Step-by-step explanation:
The given formula is 
, where A is the value of the substance in t years, and 
is the initial value
∵ The half-life is a substance is 375 years
- Substitute A by 
and t by 375 to find the value of k
∴ 
- Divide both sides by
∴ 
- Insert ㏑ in both sides
∴ ㏑( 
) = ㏑ ( 
)
- Remember ㏑ ( 
) = n
∵ ㏑ ( ) = 375 k
∴ ㏑( ) = 375 k
- Divide both sides by 375
∴ k ≈ -0.00185
∴ 
∵ 70 grams is present now
- That means the initial value is 70 grams
∴ = 70
∵ The time is 500 years
∴ t = 500
- Substitute the values of and t in the formula
∵ 
∴ A = 27.76
∴ 27.76 grams will be present in 500 years
