F (x) = 5x + 3 What is the value of x when f(x) = 6?

Mathematics

lapo4ka [179]3 years ago
6 0

Answer:

The value of x when f(x) equals 6 is 3/5.

Step-by-step explanation:

In order to solve this problem, we shall start by inputting what we know.

Since the problem provides you with the value of f(x), we will input the value in the given equation.

Original Equation: f(x) = 5x + 3

New Equation: 6 = 5x + 3

Now that all known values of variables have been added to the equation, we will begin to solve.

Start by subtracting both sides of the equation by 3. This step is necessary to isolate x in order to find it's value.

6 = 5x + 3

6 - 3 = 5x + 3 - 3

3 = 5x

Next, we shall divide both side of the equation by 5. This step will allow us to isolate x and finally solve its value.

3 = 5x

3/5 = 5x/5

3/5 = x

Thus, the value of x in f(x) = 5x + 3 is 3/5.

---

To be sure your answer is correct, insert the values of both f(x) and x into the equation provided and solve like so...

f(x) = 5x + 3

6 = 5(3/5) + 3

6 = 3 + 3

6 = 6 ✅

A triangle has one leg that is 8, one leg that is 15 and a hypotenuse that is 20. Is it a right triangle?
gregori [183]

Answer:

No

Step-by-step explanation:

A^2+b^2=c^2

8^2+15^2=20^2

64+225=400

289=400

289 does not equal 400 so it is not a right triangle

You are driving 2760 miles across the country. During the first 3 days of your trip, you drive 1380 miles. If you continue to dr
prohojiy [21]

The entire trip will take 6 days.

(Encircle this answer, as said on the directions)

Step-by-step explanation:

We know that the first three days of the trip, we traveled 1380 miles.

Find the UNIT RATE of MILES PER day:

1380/3 = 460

Unit rate = 460 miles per day

If we were to drive at this (460 mi per day) rate EACH day and the whole journey takes 2760 miles across the country.

FInd the NUMBER of DAYS of the ENTIRE TRIP:

2760/460 = 6

It will take us 6 days to drive to the destination.

Suppose you have 60 red marbles and 40 blue marbles in a
andrew-mc [135]

Answer:  The required probability is 0.26.

Step-by-step explanation: Given that there are 60 red marbles and 40 blue marbles in a  box 10 marbles are picked without replacement.

We are to find the probability of selecting 6 red marbles.

Since the marbles are picked up without replacement, so it is a situation of combination.

Let S denote the sample space of the experiment of drawing 10 marbles and E denote the event that 6 marbles are red.

So,

n(S)=^{100}C_{10}=\dfrac{100!}{10!(100-10)!}=\dfrac{100!}{10!90!}=17310309456440,\\\\\\n(E)=^{60}C_6\times^{40}C_4=\dfrac{60!}{6!54!}\times\dfrac{40!}{4!36!}=50063860\times91390.

Therefore, the probability of event E is given by

P(E)=\dfrac{n(E)}{n(S)}=\dfrac{50063860\times91390}{17310309456440}=0.26.

Thus, the required probability is 0.26.

Which value is a solution of the equation 3 - 2x=-5?<br> 02<br> 04<br> 0-2<br> 01/5
Vikki [24]
Answer: 04
Explanation: We are given 3-2x=-5. We would subtract 3 from both sides. The equation would then look like this after subtraction from both sides: -2x=-8. We would then divide -2 by both sides so we can isolate the variable. The equation would look like this x=4.
3-2x=-5
-2x=-8
x=4

Wouldn’t it be 8 1/6....I think. Because if the product is a whole number you would just add the product to the remaining whatever. So it would all together be 8 1/6 - 1/6 = 8
