I need some help with this

Answer:

Step-by-step explanation:

The domain, the possible values of x, is only limited in this function when the function is undefined. Specifically division by zero is undefined. In this case x cannot be equal to 9 because that would lead to division by zero. And that is the only restriction. So the domain is all real numbers except 9. In interval notation this is

x=(-oo, 9),(9, +oo)

Answer:

13x-9

Step-by-step explanation:

9×(x - 1)

9x - 9 +4x

collect like terms, 9x+4x=13x

Answer:

If you're asking to simplify it will be 13x-9

Step-by-step explanation:

9(x-1)+4x

=9x-9+4x (since 9*x is 9x and 9*1 is 9)

=13x-9 - By collecting like terms (9x+4x=13x)

Answer:

81

Step-by-step explanation:

thus it said 27 km/hr, she travel 27 km every hour so 27*3=81

Answer:

125

Step-by-step explanation:

86 + 17 + 11 + 11 = 125 so he made 125 snacks.

Answer:

A

Step-by-step explanation:

Option A is the correct answer.

This is true because looking at the two triangles, we discover that they are similar triangles.

As similar triangles,

1. Side TU is corresponding to side WZ and side TV is corresponding to side WY.

∴  TU/WZ = WY/TV

2. ∠T is corresponding to ∠W and ∠U is corresponding to ∠Z.

So, Option A is the statement that is true.

Answer:

P= 14

Step-by-step explanation:

Answer:

14

Step-by-step explanation:

p + 86 = 100

p = 100 - 86

p = 14

Answer:

(6+4x+8)-4-2x-5

6-4+4x-2x+8-5

2+2x+3.

Answer:

radius = 16 in

diameter = 32 in

Step-by-step explanation:

radius = the distance from the center outwards (half of the diameter)

⇒ 32 ÷ 2 = 16 in

diameter = straight across the center, from end to end

⇒ 32 in

Answer:

  vertical asymptotes

Step-by-step explanation:

The tangent function is undefined at odd multiples of pi/2. Its graph has vertical asymptotes there.

Answer:

D

Step-by-step explanation:

Answer: D

The first option is incorrect because 56+angle 3=180 and when you solve it angle 3 equals 124 degrees, not 142 degrees

The second option is incorrect because 56+43+angle 1=180 (because all triangles add up to 180 degrees). When you solve that angle 1 equals 81 degrees, not 99 degrees

The third option is incorrect because angle 1+angle 2=180, and we already know angle 1 equals 81, so when you solve that angle 2 equals 99 degrees, not 137 degrees. So we know the last option is correct.

But if you want to make sure it's correct, you can always solve for angle 4. Angle 4+43=180 degrees, and when you solve it, angle 4 equals 137 degrees, and we know that option is correct.

Hope this helped you!

Answer:

Volume is 144

m=-(5/4)

From left to right, (1,3) is first and then comes (5,-2). Always remember when finding slopes without equations, the rule is RISE over RUN, to the numerator and denominator, respectively.

The y value of the second coordinates becomes negative which is unlike the y value in the first coordinates, which means our slope is downward, meaning it has a negative sign in front.

In every slope, there’s a numerator, being the rise, and a denominator, being the run.

To find the rise, we must look at the y values. Starting at 3 going to -2 has a space of 5 units, making that our numerator.

To find the run, the first x value is 1 and the second is 5, making a space of 4, which is out denominator.

With these two numbers and the negative sign, we get -(5/4) as our slope.

Answer:

[tex]x = 2[/tex]

Step-by-step explanation:

1) Simplify 3/12 to 1/4.

[tex] \frac{x}{8} = \frac{1}{4} [/tex]

2) Multiply both sides by 8.

[tex]x = \frac{1}{4} \times 8[/tex]

3) Simplify 1/4 × 8 to 8/4.

[tex]x = \frac{8}{4} [/tex]

4) Simplify 8/4 to 2.

[tex]x = 2[/tex]

Therefor, the answer is x = 2.

Answer:

here's the solution

4t + 10 < 200

4t < 200 - 10

4t < 190

t < 190/4

t < 47.5

Answer:

28 feet.

Step-by-step explanation:

Area =  l × w

=  2 × 14

=  28 feet^2

Answer:

sin C = 40/41

cos C = 9/41

tan C = 40/9

Step-by-step explanation:

sin C = opp/hyp = c/b = 40/41

cos C = adj/hyp = a/b = 9/41

tan C = opp/adj = c/a = 40/9

Answer:

to be fair, this one is tough  :D

Step-by-step explanation:

So,  we need to figure out what 56 * 8.50 is , it's  476, now subtract that from the total sales.   3136-476=2660 ... the 2660 is the amount of sales when the adults and the kids were at the same amount.... sooo use a common variable like X.... and add up the ticket prices of 10.50+8.50 so that you have an eqution of  

x*19.00=2660.00

x=140    people

nice we have the Adults and kids ... each of 140

now just add 140+56=196 kids went to the movies

196 kids

Step-by-step explanation:

i think you just have to subtract 460-187 equals 273 so he can put 273 or something lower then that
