What point is on both lines y=12x+3 and y=x+1 <br><br> (no graph)

Mkey [24]

Step-by-step explanation:

by having two equations that have the same point, you can set the two equations equal to each other

y = 12x + 3, y = x + 1

12x + 3 = x + 1

11x = -2

x = -2/11

when you find the the x value, plug it back into either one of the equations

y = x + 1

y = (-2/11) + 1

y = 11/11 - 2/11

y = 9/11

the point (solution):

(-2/11, 9/11)

: A new bear population that begins with 150 bears in 2000 decreases at a rate of 20% per year.

d1i1m1o1n [39]

Answer:

2 bears in 2020.

Step-by-step explanation:

We have been given that a new bear population that begins with 150 bears in 2000 decreases at a rate of 20% per year.

We will use exponential decay formula to solve our given problem as:

$y=a\cdot (1-r)^x$ , where,

y = Final quantity,

a = Initial value,

r = Decay rate in decimal form,

x = Time

$20\%=\frac{20}{100}=0.20$

Upon substituting our given values in above formula, we will get:

$y=150(1-0.20)^x$

$y=150(0.80)^x$ , where x corresponds to year 2000.

To find the population in 2020, we will substitute $x=20$ in our equation as:

$y=150(0.80)^{20}$

$y=150(0.011529215046)$

$y=1.7293822569$

$y\approx 2$

Therefore, 2 bears are there predicted to be in 2020.

Since population is decreasing so population is best described as exponential decay.

The composite figure is made up of a parallelogram and a rectangle. Find the area.

MAXImum [283]

Answer: A. 76 sq. units

Step-by-step explanation:

1. You can use the following formula for calcualte the area of the parallelogram:

$A_p=b_p*h_p$

Where $b_p$ is the base and $h_p$ is the height of the parallelogram

$b_p=14units-3units-3units=8units$ and $h_p=6units$

2. The formula for calculate the area of a rectangle is:

$A_r=b_r*h_r$

Where $b_r$ is the base and $h_r$ is the height of the rectanngle.

$b_r=14units$ and $h_r=2units$

3. Then, the area of the figure is the sum of the area of the parallelogram and the area of the rectangle:

$A_f=(8units*6units)+(14units*2units)=76units^{2}$
