Answer:

a = 0, b = 6, c = 4

Step-by-step explanation:

Given

f(x) = - x² + x + 6 , then

f(- 2) = - (- 2)² + (- 2) + 6 = - 4 - 2 + 6 = 0 ← a

f(0) = 0 + 0 + 6 = 6 ← b

f(2) = - (2)² + 2 + 6 = - 4 + 2 + 6 = 4 ← c

Answer:

a = 0

b = 6

c = 4

Step-by-step explanation:

f(x) = -x² + x + 6

a = -(-2)² + (-2) + 6 = 0

b = -(0)² + (0) + 6 = 6

c = -(2)² + (2) + 6 = 4

Step-by-step explanation:

According to Boyle's law,

[tex]$ V \propto \frac{1}{P} $[/tex]

or  [tex]$ V = \frac{k}{P} $[/tex]     , where k is the proportionality constant

Given that volume is 360 cubic feet and the pressure is 46 psi.

Therefore, replacing V with 360 cubic feet and P with 46 psi in the above equation gives

[tex]$ 360 = \frac{k}{46} $[/tex]

(360)(46) = k

k = 16560

Answer: The value of x is 20

Step-by-step explanation:

The angles are vertical angles so they have to equal each other in other to solve for x.

(x + 40) = 3x          

x + 40 = 3x     subtract x from both sides

-x            -x

40 = 2x     Divide both side by 2

x= 20

Step-by-step explanation:

Find common denomianators.

1/4 = 5/20

1/10 = 2/20

Add.

5/20 + 2/20 = 7/20

Therefore, the answer is 7/20.

Best of Luck!

Answer:7/20

Step-by-step explanation:first you have to find the common denominator which is twenty. Since 4x5 is 20 you multiply the 1 by five and get 5/20.

Then since 10x2 is 20 you have to muliply

1x2 and you get 2/20. Then you and 5/20 and 2/2o and you get 7/20

Answer:

Rational Number

Step-by-step explanation:

A rational number is, by definition, a number that can be expressed as the quotient or fraction of p/q of two integers, a numerator p and a non-zero denominator q.  33/3 is a fraction of p/q of two integers, a numerator p, or 33, and a non-zero denominator q, or 3.  This makes 33/3 a rational number.

Answer:

23

Step-by-step explanation:

Since it says f(x) that means that when we see f(-6) we are substituting x for -6.

This means that the equation will become

f(-6) = -3(-6) + 5

First multiply -3 and -6 (18)

f(-6) = 18 + 5

Next add 18 and 5 (23)

This means that f(-6) = 23

23

This problem is basically asking you to plug in -6 for x and solve using the order of operations (PEMDAS)

[tex]f( - 6) = - 3( - 6) + 5[/tex]

[tex]f( - 6) = 18 + 5[/tex]

[tex]f( - 6) = 23[/tex]

See Explanation

Step-by-step explanation:

8. (1)

Area of trapezoid = 1/2(sum of || sides) *perpendicular distance

36 =1/2(x+ y) * 6

36 = ((x + y)*3

36/3 = x + y

12 = x + y

x + y = 12.... (1)

8(2)

It is given that:

x = 2y....(2)

From equations (1) & (2)

2y + y = 12

3y = 12

y = 12/3

y = 4

From equation (2)

x = 2y = 2*4

x = 8

Answer:

Emily will contribute $24 and Anna will contribute $96

Step-by-step explanation:

From the given information:

Let Emily's salary be x

and let Anna's salary be 4x since Anna's salary is four times Emily's salary.

They were to share the cost of a $120 gift card.

SO, x+4x = 120

5x = 120

x = 120/5

x = 24

Therefore, Emily will contribute x = $24

and Anna will contribute 4x = 4 × $24  = $96

Problems a through c are asking you what the values would be at those values.

What will the value of [tex]f(x)[/tex] be at [tex]x=0[/tex]? Let's look at the graph.

It seems at [tex]x=0[/tex], [tex]f(x)=0[/tex], meaning that [tex]f(0)=0[/tex]

Let's do the same for the others.

At [tex]x=-3[/tex], [tex]f(-3)=2[/tex]

At [tex]x=2[/tex], [tex]f(2)=-4[/tex]

For the last question, it is giving us the [tex]f(x)[/tex] value and asking us which [tex]x[/tex] values would give us that.

At [tex]f(x)=3[/tex], [tex]x=-2[/tex].

*Note* this function is continuous to the right, meaning that there is another point where [tex]f(x)=3[/tex].

Hope this helps.

Answer:

False

Step-by-step explanation:

Here is a counter example:

● f(x) = x^2

● g(x) = 3x

● (f○g)(x) = (3x)^2 = 9x^2 (1)

● (g○f)(x) = 3(x^2) = 3x^2 (2)

We can see that (1) and (2) aren't equal to each others.

The given statement is False

The following information should be considered:

[tex]f(x) = x^2\\\\g(x) = 3x\\\\(fog)(x) = (3x)^2 = 9x^2 (1)\\\\(gof)(x) = 3(x^2) = 3x^2 (2)[/tex]

based on the above calculations we can see that equation (1) and equation (2) are not equal to each other.
