The graph of the function f(x) = (x − 3)(x + 1) is shown.

1 answer:

3 0

The expression that describes all of the values for which the graph is positive and decreasing is all real values of x where x < -1

<h3>Which describes all of the values for which the graph is positive and decreasing?</h3>

The equation of the function is given as:

f(x) = (x - 3)(x + 1)

When the value of the graph is positive, we have:

f(x) > 0

So, the function becomes

(x - 3)(x + 1) > 0

Split the above inequality

x - 3 > 0 and x + 1 > 0

Solve for x in the inequalities

x > 3 and x > -1

Hence, the expression that describes all of the values for which the graph is positive and decreasing is all real values of x where x < -1

A football team won 10 matches out of the total number of matches they played if their win percentage was 40 then how many match

KiRa [710]

Answer:the football team played 25 games in all

Step-by-step explanation:

Let x represent the total number of matches that the football team played.

The football team won 10 matches out of the total number of matches they played. if their win percentage was 40, it means that

10/x × 100 = 40

1000 = 40x

x = 1000/40 = 25

Are these Equivalent expressions 4(2 + 3) and 4(2) + 4(3)

slava [35]

Answer:

Yes, they are equivalent.

Step-by-step explanation:

To see if they're equivalent, you have to solve them. Start with the first one. Steps are below.
Apply the distributed property: 8 + 12
8 + 12 = 20

For second expression:

4(2) = 4 × 2 = 8
4(3) = 4 × 3 = 12
Put them together: 8 + 12
8 + 12 = 20

Making a conclusion:

Because they both have the same answer, they are equivalent expressions.

I hope this helps!

How to calulate the area of a square with a perimeter of 60 inches

olasank [31]

Answer:

Step-by-step explanation:

The formula of an area of a square:

$A=s^2$

The formula of a perimeter of a square:

$P=4s$

<em />

We have a perimeter

$P=60\ in$

Substitute:

$4s=60$ <em>divide both sides by 4</em>

$\dfrac{4s}{4}=\dfrac{60}{4}\\\\s=15\ in$

Put it to the formula of an area of a square:

$A=15^2=225\ in^2$
