Y=x-3
(It goes down by 1x and 0 is -3)

AlekseyPX3 years ago

Answer:

y=x-3

Step-by-step explanation:

Everytime the x value increases the y value increases by 1

therefore the slope is 1

to solve for the y intercept, or b, plug in a point

(1,-2) for example,

-2= 1*1+b

-2= 1+b

b= -3

therefore y=x-3

Marcos purchased a sail boat for $56,900. He anticipates each year the boat will decrease in value by 8.1% from the previous yea

Varvara68 [4.7K]

Answer: $56,900\left( 0.919\right)^x$

Step-by-step explanation:

Given

Marcos purchased a sailboat for $\$56,900$

Each year the boat will decrease in value by $8.1\%$

After 1 year it is

$\Rightarrow 56,900-56,900\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\\$

after another year it becomes

$\Rightarrow 56,900\left( 1-0.081\right)-56,900\left( 1-0.081\right)\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\cdot \left( 1-0.081\right)\\\Rightarrow 56,900\left( 1-0.081\right)^2$

After $x$ years it is

$\Rightarrow 56,900\left( 1-0.081\right)^x$

$\Rightarrow 56,900\left( 0.919\right)^x$

–2z − 7 need this done now

Debora [2.8K]

Answer:

the value of the z is -3.5

Step-by-step explanation:

According to the question, the following information is given

-2z - 7

Based on the above information

We assume that we have to determine the z value

-2z - 7 = 0

-2z = 7

z = 7 ÷ -2

= -3.5

Hence, the value of the z is -3.5

The same is to be considered and relevant too

Find the exponential function that satisfies the given conditions: Initial value = 37, increasing at a rate of 5% per year

beks73 [17]

The required function is:

Option 3: $f(t) = 37. (1.05)^t$

Step-by-step explanation:

The initial value and rate is used to write exponential function

Here

Given

Initial value = 37

Rate = r = 5%

When the rate is 5%, the next year the quantity will be 1+0.05 = 1.05 time of the current quantity.

So,

The function can be written as:

$f(t) = 37. (1.05)^t$

For initial value, put t=0

$f(t) = 37. (1.05)^0\\f(t) = 37 * 1\\f(t) = 37$

Hence,

The required function is:

Option 3: $f(t) = 37. (1.05)^t$

D) 54

Step-by-step explanation:

input f(4) into x

f(x) = x² + 8x + 6

f(4) = (4)² + 8(4) + 6

f(4) = 16 + 32 + 6

f(4) = 54
