We evaluate Separately.

Let x = 5

f(5) = 2(5) + 3

f(5) = 10 + 3

f(5) = 13

Now let x = -3.

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

f(-3) = -6 + 3

f(-3) = -3

Answer:

C. f(5) = 13 and f(-3) = -3

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

f(x) = 2x + 3

x = 5

x = -3

Step 2: Evaluate

x = 5

Substitute: f(5) = 2(5) + 3
Multiply: f(5) = 10 + 3
Add: f(5) = 13

x = -3

Substitute: f(-3) = 2(-3) + 3
Multiply: f(-3) = -6 + 3
Add: f(-3) = -3

What are the zeros of the function below? F(x)= (x-1)(x+1)/6(x-4)(x+7)

Lisa [10]

Answer:

+1 and -1

Step-by-step explanation:

The function in this problem is:

$f(x)=\frac{(x-1)(x+1)}{6(x-4)(x+7)}$

First of all, we have to define the domain of the function, which is the set of values of x for which the function is defined.

In order to find the domain, we have to require that the denominator is different from zero, so

$6(x-4)(x+7)\neq 0$

which means:

$x\neq 4\\x\neq -7$

So the domain is all values of x, except from 4 and -7.

Now we can solve the problem and find the zeros of the function. The zeros can be found by requiring that the numerator is equal to zero, so:

$(x-1)(x+1)=0$

This is verified if either one of the two factors is equal to zero, therefore:

$x-1=0\\\rightarrow x=+1$

and

$x+1 = 0\\\rightarrow x=-1$

We see that both values are part of the domain, so they are acceptable values: so the zeros of the function are +1 and -1.

Rus_ich [418]

Answer:

$t=\frac{370.4-300}{\frac{300.1}{\sqrt{30}}}=1.285$

$p_v =P(z>1.285)=0.104$

Step-by-step explanation:

Data given and notation

$\bar X=370.4$ represent the sample mean

$s=300.1$ represent the sample standard deviation for the sample

$n=30$ sample size

$\mu_o =300$ represent the value that we want to test

$\alpha$ represent the significance level for the hypothesis test.

z would represent the statistic (variable of interest)

$p_v$ represent the p value for the test (variable of interest)

State the null and alternative hypotheses.

We need to conduct a hypothesis in order to check if the mean is more than 300, the system of hypothesis would be:

Null hypothesis: $\mu \leq 300$

Alternative hypothesis: $\mu > 300$

Since we don't know the population deviation, is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$ (1)

t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".

Calculate the statistic

We can replace in formula (1) the info given like this:

$t=\frac{370.4-300}{\frac{300.1}{\sqrt{30}}}=1.285$

P-value

The degrees of freedom are given by:

$df = n-1=30-1=29$

Since is a right tailed test the p value would be:

$p_v =P(t_{29}>1.285)=0.104$
