So all you really need to do is to substitute the value of x into the equation so like the 1st one will look like this: $f(-3) = 2(-3) + 4 = -2 \\ f(-1) = 2(-1) + 4 = 2 \\ f(0) = 2(0) + 4 = 4 \\ f(2) = 2(2) + 4 = 8 \\ f(4) = 2(4) + 4 = 12$ Those would be the right column for the f(x) values
Now do the same for g(x) $g(-3) = (-3)^2+1 = 10 \\ g(-1) = (-1)^2 + 1 = 2 \\ g(0) = 0^2 + 1 = 1 \\ g(2) = 2^2 + 1 = 5 \\ g(4) = 4^2 + 1 = 17$
You will notice that when x = -1, g(x) = f(x)

Answer:

500 boxes

Step-by-step explanation:

<em>hey there,</em>

<em />

< Since "p" stands for profits, change "p" to 0 (since the question says 0 profits).

Here is how your equation would look like:

$0 = -n^2 + 300n + 100000$

Pretend like "n" is "x" since that is the variable we are trying to find here.

Solve for "n". Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

"n" actually ends up equaling 500, -200.

Obviously, negative can't be the answer because you can't have a negative amount of boxes. So 500 boxes would be your answer. 200 CAN'T be your answer <em>either </em>because it is a negative!! >

What is the probability that a two-digit number selected at random has a tens digit less than its units digit

Reika [66]

The probability that a two-digit number selected at random has a tens digit less than its units digit is 0.2667 (4/15).

$A=24B=90\\\\P=A/B\\\\P=24/90\\p=4/15$

There are 90 two-digit numbers (99-9). Of these, six numbers are divisible by 15 (15, 30, 45, 60, 75, 90). This is also divisible by 5. Therefore, the preferred case is 30-6 = 24. Therefore, the required probability is 24/90 = 4/15.

The probability of an event can be calculated by simply dividing the number of favorable results by the total number of possible results using a probabilistic expression. Whenever you are uncertain about the outcome of an event, you can talk about the probability of a particular outcome, that is, its potential.

A group of 50 people were asked their gender and if they liked cats. The data from the survey are shown in the Venn diagram. Det

Alja [10]

Answer:

a = 13,

b = 28,

c = 6,

d = 22,

e = 31

Step-by-step explanation:

E = 15 +16 = 31

6 males like cats ( the middle section) so C = 6

d = 6 +16 = 22

a = 19-6 = 13

b = 50-22 = 28

so in order: a = 13, b = 28, c = 6, d = 22, e = 31

Create a system of equations that can be used to determine the rental cost of each truck for the 1-day move. Be sure to specify

bogdanovich [222]

The equation are y = 0.59x + 29.95 for company A and y = 0.79x + 19.95 for company B.

<h3>Linear equation</h3>

Linear equation is in the form:

y = mx + b

where y,x are variables, m is the rate of change and b is the initial value of y.

Let y represent the total cost of rental for each truck in x hours.

From the table, for company A:

y = 0.59x + 29.95

For company B:

y = 0.79x + 19.95

The equation are y = 0.59x + 29.95 for company A and y = 0.79x + 19.95 for company B.
