Answer:

Domain: (-∞, ∞)

Range: (-∞, ∞)

Step-by-step explanation:

The domain are the x-values included in the function (the horizontal axis).

The range are the y-values included in the function (the vertical axis).

The two arrows on the ends of the line (pointing upwards and downwards respectively) indicate that the function goes in those direction for infinity. Therefore, if there are an infinite amount of y-values, the range is (-∞, ∞).

While the slope is quite steep, there is still a slope and slowly "expands" the line on the horizontal axis. Because there is no limit to the y-values, the domain will also expand infinitely. Therefore, the domain is also (-∞, ∞).

Answer:

Domain: All real numbers (interval notation: $(-$ ∞, ∞ $)$

Range: All real numbers (interval notation: $(-$ ∞, ∞ $)$ .

Step-by-step explanation: The domain of a graph is all the x-values where the line touches or will eventually touch.

The range of a graph is like the domain, but it is all the y-values where the line touches or will touch.

In a linear function in the form y = mx + b or ax + by = c, the domain and range will always be "all real numbers" and the interval will always be (-∞, ∞). This makes sense since a line always goes on forever (unless it's piecewise or an inequality.) So the line will eventually meet every single x and y value on the xy graph.

What is the area of a triangle with vertices at (−4, 1) , (−7, 5) , and (0, 1) ?

Mekhanik [1.2K]

Plot the points on a graph. Connect the dots into a triangle. See that the height of the triangle is from y=5 down to y=1. So the height is 4 units.
Area of a triangle: A = (1/2)BH

You need to find the length of the base. Which is from point (-4,1) to (0,1). You can use the distance formula r just see from the graph that the base is 4 units.

A = (1/2)(4)(4)
A = 8

** Distance formula fyi
d² = (X-x)² + (Y-y)²
with points (X,Y) and (x,y)

The difference between a number divided by 3 and 4 is 20.

Alexxandr [17]

Let, the number be "a"

Now, according to the question,
$\frac{a}{3} - 4=20$

$\frac{a-12}{3} =20$

$a-12 =20*3$

$a-12=60$

$a = 60 + 12$

$a = 72$

So, the number is 72

Piano lessons cost $30 per lesson. Choose the graph that represents the total cost for x number of lessons. ty 150 1501 ofy y 디

Angelina_Jolie [31]

Since we are asked for tge graph that represent the total cost for the x numbers of lesson, it will be helpful to illustrate it first this way

for each lesson it will cost $30 dollars

1 lesson $30

2 lessons $60

3 lessons $90

4 lessons $120

5 lessons $150

So from this set of numbers , it is apparent that the grqph in letter c represents the total costs for x numbers of lessonsseethati

Joey earns $12 an hour. Blake earns $16 per hour. Joey receives a raise of $1.50 every six months, and Blake receives a raise of

tino4ka555 [31]

*12 + 1.5x = 16 + 0.50x*

That's the answer, since I'm late.

This is correct because when setting up this sentence as an equation, you need to look at the numbers and how they're used. There are independents and dependents.

indep.:

12,16

dep.:

1.50,0.50

Furthermore, there are 1 of each on both sides of the equation, match them from the equation by name and you get the answer.
