Answer:

Step-by-step explanation:

1) 3x + y = 3

          y = -3x + 3

When x = 0  ;   y = 0  +3 = 3                          (0 , 3)

When x = 1   ;    y = -3*1 + 3 = -3 + 3 = 0        (1 , 0)

When  x = 2   ;   y = -3*2 + 3 = -6 +3 = -3      (2 , -3)

Plot the points (0 ,3 ) ; (1 ,0) and (2 , -3) in the graph and join them

2) y = x + 3

When x = 0  ; y = 0 +3 = 3           (0 , 3)

When x = 1   ; y = 1 + 3 = 4          (1 , 4)

When x = -3  ; y = - 3 + 3 = 0      (-3 , 0)

Plot the points (0,3) , (1, 4) and (-3 , 0) in the graph and join them

3) Plug in (4 , y) int he equation

y = x + 5

y = 4 + 5

y = 9

y = 9

5) 2x + y = 3

At x-intercept y = 0

2x + 0 = 3

2x = 3

x = 3/2

Step-by-step explanation:

So, since we aren't given any options, there isn't a limit to what it is.

But, assuming you said fraction benchmark it has to be somewhere between 1/2 2/3 3/4 etc.

Now, we can convert the fractions to their equivalent decimal form

1/2 = 0.5

2/3 = 0.66 repeating.

3/4 = 0.75

Now, we can see that 0.58 is 8 units away from 0.66

We can see that it is also 8 units away from 0.5.

But, seeing to that 2/3 is 0.66 with a ton of sixes, it would in theory be away by 8.66 compared to 8 from 0.5

Therefore, we get the closest benchmark is 1/2 (0.5)

The length of the zipline is found using Pythagoras's theorem, which gives

the length of the hypotenuse side of a right triangle.

Reasons:

Height at which the zipline will be tied to one of the trees = 42 feet

Height at which the zipline will be tied to the other tree = 3 feet

The distance between the trees = 60 feet

Required:

The length of the zipline

Solution:

The length of the zipline is found as follows;

Taking one of the trees to be at the origin, the coordinates of one of the tying point = (0, 42)

The coordinates of the other tying point = (60, 3)

The in the imagined right triangle formed by the zipline and the distance

between the trees, the length of the zipline is given by Pythagoras theorem

as follows;

Length of zipline = [tex]\sqrt{(60 - 0)^2 + (3 - 42)^2} = 3 \cdot \sqrt{569}[/tex] ≈ 71.56

Length of the zipline ≈ 71.56 ft.

Answer:

16.48

Step-by-step explanation:

The round off of 16.4829 to the nearest hundredth is 16.48.

Although the term "rounding" is a general one, we typically use the terms "round up" or "round down" to indicate whether the number has gone up or down after being rounded. The supplied number is said to be rounded up when the rounded number is increased, and it is said to be rounded down when the rounded number is dropped.

Given:

16.4829

You rounded to the nearest hundredths place.

The 8 in the hundredths place rounds down to 8, or stays the same,

because the digit to the right in the thousandths place is 2.

and, When the digit to the right is less than 5 we round toward 0.

So, 16.4829 was rounded down toward zero to 16.48.

About 316,955 people

Step-by-step explanation:

The population of this city can be modeled with the formula [tex]P=I\cdot(1.05^t)[/tex], where P represents the current population, I represents the initial population, and t represents the amount of time in years since the start of the model. Plugging in 145,201 for I and (2037-2021)=16 for t, we get:

[tex]P=145201\cdot(1.05)^{16}\approx145201\cdot2.18\approx 316955[/tex]

Initial population=145,201

Total years=2037-2001=36

[tex]\\ \sf\longmapsto S=P\left(1+\dfrac{r}{100}\right)^t[/tex]

[tex]\\ \sf\longmapsto S=145201\left(1+\dfrac{5}{100}\right)^{36}[/tex]

[tex]\\ \sf\longmapsto S=145201\left(\dfrac{105}{100}\right)^{36}[/tex]

The house is right now 6years old.

" Linear equation is defined as the algebraic expression of one or more variables with highest power equals to one."

According to the question,

'x' represents the present age of house

'y' represents the years left on the mortgage

Given,

y = 24years

As per the condition given linear equation we get,

 x + y = 5x

⇒x + 24 = 5x

⇒5x - x = 24

⇒4x = 24

⇒x = 24 / 4

⇒x= 6years old

Hence, The house is right now 6years old.
