Let's solve your equation step-by-step.

9x+60=10x−2

Step 1: Subtract 10x from both sides.

9x+60−10x=10x−2−10x

−x+60=−2

Step 2: Subtract 60 from both sides.

−x+60−60=−2−60

−x=−62

Step 3: Divide both sides by -1.

−x /−1 = −62 /−1

x=62

When a breeding group of animals is introduced into a restricted area such as a wildlife reserve, the population can be expected

jasenka [17]

Answer:

A. Initially, there were 12 deer.

B. N(10) corresponds to the amount of deer after 10 years since the herd was introducted on the reserve.

C. After 15 years, there will be 410 deer.

D. The deer population incresed by 30 specimens.

Step-by-step explanation:

$N=\frac{12.36}{0.03+0.55^t}$

The amount of deer that were initally in the reserve corresponds to the value of N when t=0

$N=\frac{12.36}{0.33+0.55^0}$

$N=\frac{12.36}{0.03+1} =\frac{12.36}{1.03} = 12$

A. Initially, there were 12 deer.

B. $N(10)=\frac{12.36}{0.03 + 0.55^t} =\frac{12.36}{0.03 + 0.0025}=\frac{12.36}{y}=380$

B. N(10) corresponds to the amount of deer after 10 years since the herd was introducted on the reserve.

C. $N(15)=\frac{12.36}{0.03+0.55^15}=\frac{12.36}{0.03 + 0.00013}=\frac{12.36}{0.03013}= 410$

C. After 15 years, there will be 410 deer.

D. The variation on the amount of deer from the 10th year to the 15th year is given by the next expression:

ΔN=N(15)-N(10)

ΔN=410 deer - 380 deer

ΔN= 30 deer.

D. The deer population incresed by 30 specimens.

Which of the equations below could be the equation of this parabola?

Vilka [71]

Answer:

Step-by-step explanation:

Parabola that is opening upward has the form $y=ax^2$
Parabola opening downward has the form $y=-ax^2$
Parabola opening leftward has the form $x=-ay^2$
Parabola opening rightward has the form $x=ay^2$

Where a is a constant

Now, looking at the graph given, it takes the form $x=-ay^2$

Where a is 3 (matching the answer).

Hence, B is the correct answer choice.
