The function f is defined by f(x)=7x−5. Use this formula to find the following values of f. <br>f(3)
Korvikt [17]

Answer:

f(3) = 16

Step-by-step explanation:

f(x)= 7x-5

We want to find the value when x=3

f(3) = 7*3 -5

f(3) = 21-5

f(3) = 16

Please Answer Quick 70 Points !
Kipish [7]

Answer:

The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true

The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false

Step-by-step explanation:

we have

2x-y=-5 -----> First equation

x+3y=22 -----> Second equation

Solve the system of equations by graphing

Remember that the solution of the system is the intersection point both graphs

The solution is the point (1,7)

The ordered pair (7,19) lie on the first line, so is a solution of the first equation

see the attached figure

<u><em>Verify each statement</em></u>

case 1) The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true

The statement is true

case 2) The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true

The statement is false, because the ordered pair (7,19) not lie on the second line

case 3) The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false

The statement is true

case 4) The ordered pair (7, 19) is a solution to the system because it makes both equations true

The statement is false,because it makes only the first equation true

Answer:

22.9 feet

Step-by-step explanation:

You are using Tangent because you have the opposite and adjacent sides

Tan 5 = 2/x

x Tan 5= 2

x= 2/Tan5

= 22.860

Please halp. i am not smart

Let's start with 22-C!

To figure out the problem, let's establish what it's asking. It wants to know the one time fee of using the trash dumpster. Your teacher may have taught you a better way to do this, but I'll show you how to solve it via logic.

We first need to set up a basic equation. X will be the unknown fee, 195 will act as the total, and 9(15) will represent the remaining cash (you get this from 15$ an hour for 9 hours).

The equation should look something like this:

x + 9(15) = 195 OR (simplified) x + 135 = 195.

At this point we can solve it like a regular equation. Subtract 135 on both sides:

x = 60. Therefore, the fee for using the dumpster is 60$.

Now we can move on to 23-A & B!

First, let's go over 2 basics: point slope formula and slope intercept.

Point slope formula: <em>y - yy-y_{1} = m(x - x_{1} )</em>

Slope intercept: <em>y = mx + b</em>

We know that .5 is the slope because it's dependent on an amount of time (or dependent in general). 64 can be used as y1 and 48 as x1.

The formula would be: y - 64 = .5(x - 48).

As for part B, we plug in the same numbers! We've previously found that .5 is the slope (m) and it appears you already know that the y-intercept (b) is 40. Plug it in like so:

y = .5x + 40

All of the answers are bolded, I hope this helped!
