Any one Know the Answer To This Algebra 1

Mathematics
1 answer:
alexdok [17]3 years ago
3 0

Answer:

The correct answer is B. -3.

Step-by-step explanation:

To solve this problem, we need to plug in -3 for all of the values of x in the equation.  If we do this, we get:

f(x) = 2x + 3

f(-3) = 2(-3) + 3

Now, we can just simplify the expression found on the right side of the equation using PEMDAS.  First, we should perform the multiplication.

f(-3) = -6 + 3

Next, we should add our final two terms together.

f(-3) = -3

Therefore, the correct answer is -3.

Hope this helps!

Christine performed the following experiment 20 times using a book that contains 462 pages.
wel

Using the probability concept, it is found that there is a 0.3 = 30% experimental probability that Christine will randomly choose a page that is divisible by 3.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In an experimental probability, these number of outcomes are taken from previous trials.

In this problem:

  • The experiment was made 20 times.
  • Of those, in 6 experiments(81, 105, 171, 159, 297, 387) she choose a page that was divisible by 3.

Then:

p = \frac{6}{20} = 0.3

0.3 = 30% experimental probability that Christine will randomly choose a page that is divisible by 3.

Linear or non linear
Alja [10]

<u>Answer</u>:

Linear equation.

<u>Explanation</u>:

It is linear as y increases 11 grids with every increase in x grid.

OR,

I will make a linear equation from two coordinates: (1,11),(2,22)

slope: \frac{y2-y1}{x2-x1} → \frac{22-11}{2-1} → 11 is the slope

the find equation using:

y - y1 = m(x - x1) → y - 11 = 11(x-1) → y = 11x ....this is linear equation.

Therefore it's linear.

OR,

Then check if 3rd and 4th coordinate matches the equation.

y = 11x                                                      y = 11x

y = 11(3)                                                    y = 11(4)

y = 33 ...therefore matches                    y = 44...therefore matches

So, its a linear equation.
