Given:

The equation of line is

[tex]y=-\dfrac{1}{2}(x-18)[/tex]

The perpendicular line intersect the y-axis at (0,-1).

To find:

Equation of perpendicular line.

Solution:

Point slope form of a line is [tex]y-y_1=m(x-x_1)[/tex], where m is slope.

We have,

[tex]y=-\dfrac{1}{2}(x-18)[/tex]

Thus, the slope of this line is [tex]m_1=-\dfrac{1}{2}[/tex].

Product of slopes of two perpendicular lines is -1.

Let the slope of perpendicular line is [tex]m_2[/tex]. Then,

[tex]m_1\times m_2=-1[/tex]

[tex]-\dfrac{1}{2}\times m_2=-1[/tex]

[tex]m_2=2[/tex]

Slope of perpendicular line is 2 and it passes through (0,-1). So, the equation of perpendicular line is

[tex]y-(-1)=2(x-0)[/tex]

[tex]y+1=2x[/tex]

[tex]y=2x-1[/tex]

Therefore, equation of perpendicular line is [tex]y=2x-1[/tex].

Answer:

The answer is one pair of socks = $10

Step-by-step explanation:

I subtracted 42 by 12 and got 30. I then divided 30 and 3 and got 10.

42-12=30

30/3=10

Or you can subtract 12 from both sides to get the variable on one side. Then you divide the variable by the coefficient (3) and divide 30 by 3 to get 10.

The cheetah can run 2.42 km in 90 seconds

From the question, we are to determine how fast the cheetah could run in 90 seconds

First, we will convert the speed to meter/seconds

The given speed = 97 km/hour

97 km/ hour  = (97 × 1000 /3600) m/s

97 km/hours =  26.9444 m/s

Now, using the formula,

Distance = Speed × Time

From the given information,

Time = 90 seconds

∴ Distance = 26.9444 × 90

Distance = 2424.996 m

Distance = 2.424996 km

Distance ≅ 2.42 km

Hence, the cheetah can run 2.42 km in 90 seconds

Step-by-step explanation:

5.50+0.85x=

The function rule to find the cost to ship a package that weighs [x] ounces is c[x] = 0.85x + 5.5.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is the cost of shipping a package overnight from San Antonio to Dallas, which is $5.50 plus $0.85 per ounce.

We can write -

Fixed cost of shipping overnight = $5.50

Cost per ounce for shipping = $0.85

The function rule that could be used to find the cost to ship a package that weighs [x] ounces will be -

c[x] = 0.85x + 5.5

Therefore, the function rule to find the cost to ship a package that weighs [x] ounces is c[x] = 0.85x + 5.5.

Answer:

Step-by-step explanation:

The set of ordered pairs {(1 , 7) , (−1 , 7) , (8 , −6) , (−3 , 2)} is a function

The set of ordered pairs {(4 , 7) , (−1 , 2) , (4 , −6) , (−3 , −2)} is not a

function

The set of ordered pairs {(3 , 7) , (−1 , 2) , (−4 , −2) , (−3 , −2)} is a function

The set of ordered pairs {(−3 , 7) , (1 , 2) , (4 ,−2) , (12,−4)} is a function

An ordered pair represents a relationship between two values

The first value is the input the second value is the output

1. A relation is a set of inputs and outputs

2. A function is a relation with one output for each input

3. All functions are relations

{(1 , 7) , (−1 , 7) , (8 , −6) , (−3 , 2)}

∵ Each x-coordinate in each ordered pair has only one y-coordinate

∴ The relation above is a function
