lidiya [134]2 years ago

Answer:

f(x) = -5x - 2

Step-by-step explanation:

Plug in the first set of values into each possible equation. Whichever equation yields the correct ouputs (y-values) for ALL input (x-values) is the correct answer. For the function f(x) = -5x - 2,  f(-2) = 8, f(-1) = 3 and so on... So f(x) = -5x - 2 is the correct answer!

Hope this helps!

Given: 2x + b &gt; -3. Find the value of b so that x &gt; 3<br>Help a s a p please
masya89 [10]

Answer:

Step-by-step explanation:

To find the value of b, we need to isolate it on one side of the inequality. We can do this by subtracting 2x from both sides, which gives us b > -3 - 2x.

Since we want x to be greater than 3, we can plug in the value 3 for x on the right-hand side of the inequality. This gives us b > -3 - 6, or b > -9.

Therefore, the value of b that makes the inequality true is any value that is greater than -9. For example, b could be -8, -7, -6, or any other value that is greater than -9.

To check if our solution is correct, we can plug in the value of b and the value of x (3) into the original inequality to see if it is true. If we plug in -8 for b and 3 for x, we get the inequality 2x + b > -3, which simplifies to 2 * 3 + (-8) > -3, or 6 - 8 > -3, which is true. Therefore, our solution is correct.

What number between 20 and 25 is a prime number?
Elena-2011 [213]
Prime numbers are numbers that have only one factor pair; 1 and themselves.

Let's start from 21.

21 = 1 x 21, 3  x 7.
This has two factor pairs, this is not prime.

Let's try 22.

22 = 1 x 22, 2 x 11.
This also has two factor pairs, this is not prime.

Let's try 23.

1 x 23.
This is a prime number, as it only has one factor pair; 1 and itself.

23 is your prime number.

I hope this helps!

A construction crew is lengthening a road that originally measured 47 miles. The crew is adding one mile to the road each day. L
Dmitry_Shevchenko [17]

Answer:

78 miles

Step-by-step explanation:

Given that:

Original length, L = 47 miles

Additional length (miles) added per day, = 1 mile

Representing as an equation :

L(D) = original length + additional length per day * number of days

Let, D = number of days

L(D) = 47 + D

Length after 31 days :

L(31) = 47 + 31

= 78 miles

When given a graph, the vertical line test can be used to determine functionality. Describe the vertical line test and explain t
diamong [38]

Answer:

The vertical line test is a way for you to see if a graph represents a function. It allows you to identify if any x values have more than one y value.

A graph would be a function if every input (x) has exactly one output (y). A graph would not be a function if an input (x) has more than one output (y).

Step-by-step explanation:

In a function, every input within the domain of the function must have exactly one output. If the graph has an input that has more than one output, then it is not a function. The vertical line test is what allows you to see if a graph is a function or not.
