Answer:

(-4,-8)

Step-by-step explanation:

Answer:

The answers to the blanks are:

The “?” in the table represents the number 38 because the average rate of change on every interval of the function is 1/3.

Step-by-step explanation:

How you can see in the table, after the first values [x=-2, f(x)=5], each time that x add 1, f(x) add 3, (that is the reason why the average rate is 1/3), how you can see below:

2. x = 2 (were added 4 to the first number -2)

   f(x) = 17 (were added 12 to the first number 5)

3. x = 5 (were added 3 to the second number 2)

   f(x) = 26 (were added 9 to the second number 17)

4. x = 9 (were added 4 to the third number 5)

How in the last column were added 4, you must multiply this value by 3 (remember the average rate), so 4*3 = 12, now:

  f(x) = 38 (were added 12 to the third number 26)

Answer:

(2 1/2, 0)

Step-by-step explanation:

In the picture attached, the complete question is shown.

f(x) = 2 1/2 - 3 1/3 * x

or

f(x) = 5/2 - (10/3)*x

f^-1(x) is the inverse of f(x), which is obtained replacing f(x) by x, and x by y, and solving for y, as follows:

x = 5/2 - (10/3)*y

(10/3)*y = 5/2 - x

y = (5/2)*(3/10) - x*(3/10)

y = (3/4) - (3/10)*x

f^-1(x) = (3/4) - (3/10)*x

at x-intercept, f^-1(x) = 0,

(3/4) - (3/10)*x = 0

(3/4) = (3/10)*x

x = (3/4)*(10/3)

x = 5/2 or 2 1/2

Answer:

each coat $15

Step-by-step explanation:

$78-$18 divided by 4 =15

hope this helps :)

Answer:

The answer is that each shirt and pair of pants costs 15$

Step-by-step explanation:

So you have 78$, and you already need to buy a backpack so then you have 60$ dollars because the backpack is 18$, and 2 shirts and 2 pairs of pants is 4 pieces of clothing in all, 60$ divided by 4 pieces of clothing equals 15$ per piece of clothing (78 - 18 = 60 divided by 4 = 15)

Answer:

Step-by-step explanation:

160=25%

25 times 4=100

therefore 160 times 4=100%

Answer:

$9

Step-by-step explanation:

Given  I owe my friend $16 and my mom owes me $25

step 1-->take back money from mom

Mom gives back you $25

Now you have $25

Step 2: return the money you owe to friend

you owe $16

You have $25 and return $16

Thus , money you will have = money you have - money you return

money you have = $25 - $16 = $9

Thus, you will have $9 , after all is settled.

Answer:

18 Boards

Step-by-step explanation:

Convert 6ft into inches,

[tex]6*12=72[/tex] (inches high stack)

Divide the result by four (the height of each board),

[tex]72/4=18[/tex]

Answer:

B

Step-by-step explanation:

A=r²π

d=2r

Plug in the values.

d=12

C=12π

A=36π

Answer:

C = 14pi

Step-by-step explanation:

C = pi d

The radius is 7 so the diameter is

d = 2r

d = 2*7

=14

C = pi *14

C = 14pi

Answer:

Step-by-step explanation:

we know circumference of a circle = [tex]\pi[/tex]d

here radius = 7 mm

diameter = 2*7= 14mm

therfore circumference = [tex]\pi[/tex] * 14

ie C = 14[tex]\pi[/tex]

Answer:

  C(3, −3), D(−2, −3)

Step-by-step explanation:

The given segment is 5 units long. (You can subtract the coordinates or count the grid squares to see this.)

In order for the area to be 30 square units, the product of length and width must be 30.

  30 = 5×width

  30/5 = width = 6

The horizontal line that is 6 units below the one shown is at y = -3. That is, the coordinates of C and D will have y-values of -3. Only one answer choice matches.

Answer:

C(3, −3), D(−2, −3)

Step-by-step explanation:

Steps:

12* 8 = 96 + two side of triangle (32 when combined) is 128.

Since 1 mile = 1.609344 km

We simply have to multiply the number of miles by 1.609344.

Mathematically speaking:

27 x 1.609344 = 43.4522 km

The closest result is option a. 43.443 km.

5s = -15

Divide by 5

5s/5 = -15/5

s = -3

Answer:

-3

Step-by-step explanation:

1) combine like terms:

5s--19=4

5s+19=4

subtract 19 from both sides:

5s=-15

s=-3

Answer: $8,925

Step-by-step explanation:

Convert 15% to decimals. You can do this by dividing by 100.

[tex]\frac{15}{100}=0.15[/tex]

Now, take the total amount of the sales and multiply it by this decimal.

[tex]59,500*0.15=8925[/tex]

Step-by-step explanation:

I think writing the given out helps a bit.

x = small angle

2x+3 = large angle <-- it's 2x since it's twice the small angle and +3 because it's 3 degrees more than the small angle.

small angle + large angle = 180

Now just substitute!

[tex]x+(2x+3)=180\\3x=177\\x=\frac{177}{3} \\x=59[/tex]

Now that you know what x equals (aka the smaller angle) now you can find the larger angle.

[tex]2(59)+3\\118+3\\121[/tex]

Answer:

The smaller angle equals 59°

The larger angle equals 121°

[tex]F = \frac{Gm_{1}m_{2} }{d^{2} }[/tex]

F x [tex]d^{2}[/tex] = G[tex]m_{1}m_{2}[/tex]

[tex]d^{2}[/tex] = [tex]\frac{Gm_{1}m_{2}}{F}[/tex]

d = ±[tex]\sqrt{\frac{Gm_{1}m_{2}}{F} }[/tex]

Since "m1" and "m2" represent different masses, we can change them to different letters. This will make it easier to solve.

m1 = m

m2 = n

F = G*m1*m2/d^2 → F = Gmn/d^2

Steps to solve for d:

F = Gmn/d^2

~Multiply d^2 to both sides

d^2 * F = d^2 * Gmn/d^2

~Simplify

d^2 * F = Gmn

~Divide F to both sides

d^2*F/F= Gmn/F

~Simplify

d^2 = Gmn/F

~Take the square root of both sides

√d^2 = ±√Gmn/F

~Simplify

d = ±√Gmn/F

Since we are done solving for d, we can input "m1" and "m2" to replace "m" and "n".

d = ±√Gmn/F → d = ±√G*m1*m2/F

Therefore, the answer is [ d = ±√G*m1*m2/F ]

Best of Luck!

Answer:

b=15

Step-by-step explanation:

360-90=270

270+60=330

360-330=30/2=15

Answer:

The measure of angle b is 15 degrees,

Step-by-step explanation:

Both triangles are isosceles. The inside one is also a right triangle. Since the big triangle is isosceles and the two angles add up to 120 degrees, they also have to be equal, meaning ∠P≅∠R=60 degrees. The inside triangle is also isosceles, meaning that m∠a=60°-b, which 60°-b representing the measure of the last angle in the smaller triangle. Since ∠a and the third angle are congruent, they each have to equal 45°. 60°-45°=15°. The measure of ∠b=15°.

Answer:

[tex]a_{n}[/tex] = 20n + 12

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 52 - 32 = 72 - 52 = 92 - 72 = 20

This indicates the sequence is arithmetic with explicit formula

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 32 and d = 20, thus

[tex]a_{n}[/tex] = 32 + 20(n - 1) = 32 + 20n - 20 = 20n + 12

Answer:

-2g+3

Step-by-step explanation:

-4g + 8 - 5 + 2g

= (-4g+2g) +(8-5)

= (2-4)g + 3

= -2g +3

This equation is simplified as you can't solve it further

Answer:

-2g + 3

Step-by-step explanation:

Add like terms (-4g and 2g, 8 and -5), like so:

-4g + 2g = -2g

8 - 5 = 3

Put it all together:

-2g + 3

Answer:

A)  -2/3

Step-by-step explanation:

To find the answer look at what it's asking you to do.  (f/g) means to divide f(x) by g(x).

[tex](f/g)(x)=\frac{2x}{x^2+2}[/tex]

Now you need to find (f/g)(-1).  Plug in -1 wherever there is an x and simplify.

[tex](f/g)(-1)=\frac{2*-1}{(-1)^2+2}\\ (f/g)(-1)=\frac{-2}{1+2}\\ (f/g)(-1)=\frac{-2}{3}[/tex]

Your answer is -2/3
