if f(x)=6x+9 and g (x) =-x-6 , what is (f+g)(x) ?

Answer:

40 percent of 55 is 22

I hope this helps you!

Answer:

Step-by-step explanation:

The 40% goes with the 55. The equation looks like

Answer: 40/100 * 55

Answer: 22

Answer:

y = -1/4x - 5/2.

Step-by-step explanation:

I am assuming you mean y = -1/4x + 5.

This has slope of -1/4 so the required equation has the same slope ( as they are parallel).

Using the point-slope form of the equation of a line:

y - (-3) = -1/4(x - 2)

y + 3 = -1/4(x - 2)

y = -1/4x + 1/2 - 3

y = -1/4x - 5/2

Answer:

x = 6

Step-by-step explanation:

Area of a rectangle = length * width

24 = (x+2) (2x-9)

24 = 2x^2-5x-18

0 = 2x^2-5x-42

0 = (2x+7) (x-6)

0 = (2x+7) or 0 = (x-6)

-7 = 2x or 6 = x

-7/2 = x

Because (-7/2)+2 = -3/2 and a side can not be equal to a negative measurement, x cannot be equal to -7/2.

24 = ((6)+2) (2(6)-9)

24 =24

so x = 6

Hello there!

The slope is -2/3x.

Why? Keep the following formula in mind:

y=mx+b

m is the slope (-2/3x in this case)

b is the y-intercept (-5 in this case)

Hope this helps!

Answer:

A. 9.49

Step-by-step explanation:

Use Pythagorean theorem to find the distance and make a right triangle.

So then..

a² + b² = c²

3² + 9² = c²

c² = 9 + 81

c² = 90

c² = [tex]\sqrt{90}[/tex]

c = 9.49

Answer:

I think it is B

Step-by-step explanation:

Angle AMB is not more than 90 and less than 180 degrees, and neither is angle BMC. Therefore, neither angle is obtuse.

In [tex]\angle[/tex] A, [tex]\angle[/tex] BMC is an obtuse angle.

In [tex]\angle[/tex] B, [tex]\angle[/tex] AMB is an obtuse angle.

In [tex]\angle[/tex] D, [tex]\angle[/tex] AMB is an obtuse angle.

But, in C there are two right angles

Therefore, two right angles exist supplementary.

When the sum of the measures of two angles is 180°, such angles are called supplementary angles and each of them is called a supplement of the other.

Two angles exist named supplementary when their measures count up to 180 degrees. By the explanation of obtuse angles, the angles that estimate more significant than 90° exist as obtuse. If we add two obtuse angles, the sum will be more significant than 180°. It will not help the results of the supplementary angles when we add obtuse angles.

In [tex]\angle[/tex] A, [tex]\angle[/tex] BMC is an obtuse angle.

In [tex]\angle[/tex] B, [tex]\angle[/tex] AMB is an obtuse angle.

In [tex]\angle[/tex] D, [tex]\angle[/tex] AMB is an obtuse angle.

But, in C there are two right angles

The two right angles exist supplementary.

Therefore, the correct answer is option B.

Assuming 4(2) is meant to be f(2).

Step-by-step explanation:

I'm not sure what 4(2) means.  I'll assume f(2) was intended in this answer.

We have a function, f(x)=3x+5, where the value of the function depends on the value of x.  f(2) means x=2, so we would write:

f(2)=3x+5

f(2)=3*(2)+5

f(2)=6+5

f(2)=11

Step-by-step explanation:

the number of bottles per minute would equal the rate of change, or 'slope'

the slope formula is 'the difference of the two y-values / difference of the two x-values'

Step-by-step explanation:

10.63 + 9(6x - 5) = 6(5x + 8) - 6x

10. 63 + 54x - 45 = 30x + 48 - 6x

-34.37 + 54x = 24x + 48
