Answer:

x= 20

Step-by-step explanation:

The sum of the angles of a triangle are 180 degrees

x+5  + 7x-5   + x  =180

Combine like terms

9x = 180

Divide by 9

9x/9 = 180/9

x = 20

Answer:

Below.

Step-by-step explanation:

A. 75, 250 and 50.

B.  75+250+50 = 375.

C. -50 and -150.

D.  -50 + -150 = -200.

E.  375 - 200 = 175.

Answer:

This sign ≤ means greater than or equal to

but, this sign < means the number which is in the side is only greater

That why the sign ≤ is used

My this answer might be wrong , because in b ≤ 45 , I am confused from where the letter " b " came from .

Answer:

D. 8.053 x 10^4

Step-by-step explanation:

Given :

7.17 x 10^4 and 8.17 10^5

The number in between the two Given numbers should be greater Than 7.17*10^4 but less than 8.17*10^5

A. 6.92 x 10^4 - this is less than 7.17 * 10^4 ; hence doesn't fit in

B. 7.2 x10^9 - this is greater than both values, hence, doesn't fit in

C. 7.57 x 10^3 - this is less than 7.17*10^4 ; hence does not fit in

D. 8.053 x 10^4 - this fits in as it is greater than 7.17*10^4 and less than 8.17*10^5 ; hence, it is the correct answer.

Answer:

C

Step-by-step explanation:

convert option a to the lowest term

10 : 35 = 2: 7 (divide both ratios by 5)

8 : 28 = 2 : 7 (divide both ratios by 7)

convert option b to the lowest term

4 : 10 = 2 : 5  (divide both ratios by 2)

10 : 25 = 2 : 5  (divide both ratios by 5)

option c

divide 40km/h by 60 to convert to km / min

40/60 = 0.7 not equivalent

option d

Answer:

Step-by-step explanation:

Average rate of change of a function between interval x = a and x = b is given by,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

Average rate of change of the function in the interval [-4, -2]

= [tex]\frac{f(-2)-f(-4)}{-2-(-4)}[/tex]

= [tex]\frac{0-(-12)}{-2+4}[/tex]

= 6

Average rate of change in the interval [-2, 1]                                                                            

= [tex]\frac{f(1)-f(-2)}{1-(-2)}[/tex]

= [tex]\frac{3-0}{1-(-2)}[/tex]

= 1

Average rate of change in the interval [-3, 1]

= [tex]\frac{f(1)-f(-3)}{1-(-3)}[/tex]

= [tex]\frac{3-(-5)}{1+3}[/tex]

= 2

Average rate of change in the interval [-4, 0]

= [tex]\frac{f(0)-f(-4)}{0-(-4)}[/tex]

= [tex]\frac{4-(-12)}{0-(-4)}[/tex]

= 4

Answer:

-16

Step-by-step explanation:

When adding a negative and a positive number, you need to keep in mind that your are essentially adding.

so if I have a number line

-24, -23, -22, -21, -20, -19, -18, -17, -16, -15, -14,,,,

you will start at -24 and will go up the number line (to the right) 8 times and that should get you your answer.

Answer:

16

Step-by-step explanation:

4 option: Pork, chicken, beef, or veggie burritos.

and for each of the 4 options: rice, beans, hot or mild salsa.

4x4=16

Example:

Pork with rice

Pork with beans

pork with hot salsa

pork with mild salsa

etc.

Pork: 4 possibility

Chicken: 4 possibility

Beef: 4 possibility

Veggie burritos: 4 possibility

4+4+4+4=16

Hope this answer help you.

Answer:

D

Step-by-step explanation:

The equation is going to by

y = (x - 2)(x - 3)         Multiply to remove the brackets.

y = x^2 - 2x - 3x + 6

y = x^2 - 5x + 6       Now what you are going to do is complete the square.

y = (x^2 - 5x  +  __ ) +6

Take - 5

Divide it by 2 = -5 / 2

and square it = (-5 / 2)^2 = 25/4

Put this result inside the brackets.

y = (x^2 - 5x + 25/4 ) + 6               Now subtract 25/4 after the 6

y = (x^2 - 5x + 25/4) + 6 - 25/4

y = (x - 5/2)^2 - 1/4

The x coordinate of the vertex  is 5/2

You could also do this by using x = -b/2a = - -5/2*1 = 5/2

Step-by-step explanation:

I'm so sorry if it is wrong!!

Option D is correct, the equation represented by the function g(x) is  ∛x - 1.5.

The graph of g(x) is a translation of y =∛x

We have to find the equation which represents the g(x).

if x=9 then the value of y is 3 in the f(x).

For the translation of the graph y = ∛x would be in the form g(x) = ∛(x - h) + k, where (h, k) represents the horizontal and vertical shifts of the graph, respectively.

There is a vertical shifts in the translation.

As we observe the function when x is 9 the y value is decreased by 1.5.

So the function g(x) would be ∛x - 1.5.

Hence, the equation represented by the function g(x) is  ∛x - 1.5.

Instead of using the quotient rule, you can first expand y :

y = (4x - 1)^2 / x ^2 = (16x ^2 - 8x + 1) / x ^2 = 16 - 8/x + 1/x ^2

Then the derivative is

dy/dx = -8/x ^2 - 2/x ^3

The tangent to the curve at (-1, 25) then has a slope or gradient of

dy/dx = -8/(-1)^2 - 2/(-1)^3 = -6

Answers:

RS = 13

ST = 8

==================================================

Explanation:

S is between R and T. I'm assuming also that S is on line RT.

If that's the case, then by the segment addition postulate, we can say  RS+ST = RT.

In other words, the longest segment RT is broken into two smaller pieces RS and ST (not necessarily equal but they may be). Gluing the pieces back together should get us the original longest segment.

---------------

Apply substitution and solve for x.

RS+ST = RT

(2x+5)+(3x-4) = 21

(2x+3x)+(5-4) = 21

5x+1 = 21

5x = 21-1

5x = 20

x = 20/5

x = 4

--------------------

If x = 4, then,

Then notice how RS+ST = 13+8 = 21, which is is the length of RT

This confirms that RS+ST = RT is true and it confirms our answers.
